Smart means ‘efficient’

Keeping pace with the rapid socio-economic development, most cities across the globe are becoming ‘smart’. Apart from considering the lifestyles of the citizens, the smart cities are built in way to be efficient. As energy efficiency plays a critical role in creating sustainable infrastructure, deploying energy-efficient solutions is the key in making a city truly ‘smart’.

And the process should start from the conceptualisation of a building. Incorporating energy efficiency measures at design stage increases the potential of energy savings. Designing a building in a climate responsive way is considered to be the most cost-effective way to reduce the energy consumption. Experts observe that incorporating appropriate strategies in the design stage, the energy savings potential would be about 40-50 per cent.

Also, achieving energy efficiency in the process of construction is vital. During the construction stage, the impact on air and water quality, surrounding developments and microclimate should be reduced. Use of energy-efficient machines and eco-friendly building materials also play its role in achieving efficiency.

Speaking at the event M Venkaiah Naidu said “India is on the brink of urban revolution. 32 per cent of the country’s population is living in urban areas but contributing 60 per cent GDP of the country. Today urban areas are at the heart of many great challenges, opportunities and promise. Since long time development of cities was ignored even as the urban population increased. It has resulted in the haphazard expansion of cities and rapid growth of slums. To overcome these challenges we all have to work together. Transparency and accountability has to be the basic principle of Governance.”

P

lanet 3 Studios, founded by Kalhan Mattoo and Santha Gour Mattoo, has evolved as a multidisciplinary practice with a rapidly growing eclectic portfolio of projects. The essence of their design principle is to address the fundamentals through intense programming. In an exclusive interview with ACE Update, Ar. Kalhan Mattoo shares his architectural journey and vision Journey in architecture Architect Kalhan Mattoo and Santha Gour Mattoo had an opportunity to independently work on a 40-acre residential project while interning before graduation. The experience of working with a team and taking responsibility for delivering a full set of presentation material was an invaluable experience to kick-start their career aspirations. The very next assignment couldn’t have been more different. RPG Group gave them a challenge to design and build a 600-sq.-foot office in 20 days to accommodate 42 people. The budget was a measly 1.5 lakh and this was an impossible challenge on all possible levels. They delivered in 18 days and with a profit worth a smile. This taught them to question notions, to learn from constructors, to get hands dirty, and to take singular responsibility for outcome. From night clubs to places of worship, hotels to hospitals, landscape to facades, master plans to product design, cities to small bus stops, they have approached the all with a beginners mind and offered ideas that become agents of positive change. Never bogged down by dictates of style or ideology, they have freely explored within the opportunities presented. They are asked often what they ‘specialise’ in, and their response remains ‘nothing’ in particular. Domain expertise in a specific typology is not what they seek; they are more interested in learning from varied base of experiences and applying that outside perspective to solve particular design challenges. Their evolution as a design studio has happened with big creative ideas and that hopefully will remain the essence of their way.

Challenges faced Ideas that challenge entrenched notions invariably face headwinds when pushed forward. Beyond that, the very nature of architecture profession that makes design dependant on external patronage naturally introduces an element of risk in the dynamic.

Architect Kalhan and Santha Gour Mattoo have had their share of disappointments with good projects stalled, shelved or killed for reasons beyond their control. The current scale of compensation in their industry leaves a lot desired, and they struggle to resource their project teams to the extent required. Quality of available projects is another challenge. Some of the best projects in the country go to Twin Towers, Silver Springs, Indore

Interview II The Big Architect foreign practices or established local firms and very little opportunity to younger architects to showcase talent.

We lack the culture of competitive design bidding that does not discriminate against newer practices. There is precious little the government is doing as prime patron of arts, and the few opportunities are pushed out of reach with stringent pre-qualification requirements designed to maintain status quo. Beyond this, regressive and design unfriendly regulations, low level of awareness of design and art, meagre construction budgets, skill deficit in construction industry, and poor project planning and management challenge them on regular basis.

Achievements Architect Kalhan Mattoo and Santha Gour Mattoo have always celebrated any success, especially if it’s something that they have done differently in a fundamental way.

Their very first architectural project was a college that was designed on a radically different programme and on principles that challenged prevalent thinking. Its success and recognition encouraged them to stay the path. Similarly, their first product design, a workstation that could be shut, stacked and moved about received acclaim for innovation and an international design award.

The first resort they designed made it to popular lists of top upcoming resorts worldwide for its dramatic form as well as in its success in combining the best of dispersed format and monolithic hotel typologies. Currently, they are enthused about a 60-acre community master plan that they are on-site with and the mandate extends up to interior design of individual units as well. At the heart of the development, there is a 1-km green walk that runs through orchards, organic farms and other communal landscape spaces. They hope to have similar acceptance for the idea that communities can be held together by shared activities and fortunately the developer shares that view.

Future outlook These are exciting times to be in! Planet 3 Studios is exploring parametric and computational design tools that fundamentally change the manner in which Mattoo duo create design. They literally created the design of a whole campus in a North Indian town using scripts that define usage parameters instead of drawing out the design intent. They have just completed the construction of an auditorium in central Mumbai that was designed by simulating the sound waves emerging from stage and modelling the space to respond to that key parameter.

This kind of methodology offers the opportunity to check and vet key performance criteria and allow them to do a more informed design based in intelligence rather than aesthetic whim.

They are working across the country on projects that range from concepts for new cities, master plans and right down to design of individual buildings and even interiors. It may

seem like a lot on plate for a mid-sized studio, but they are fully involved in what they take on. The quality of their team and engagement makes it possible to maintain a high degree of design integrity. They are looking forward to bigger and worse challenges still.

Five worst architectural designs in India Planet 3 Studios would desist from judging others work but the worst would be the ones that have zero design ambition and not necessarily ones that tried something and failed. The government is a big patron of generic architecture, and one only needs to look around to see what could easily have been done better. n

Energy Efficiency II Cover Story

Energy-efficient buildings WHY & HOW?

Achieving the common goal of sustainability and awareness for energy-efficient structures isn’t difficult anymore

E

nergy efficiency is the first big step towards achieving sustainable buildings. Energy efficiency helps control rising energy costs, reduce environmental footprints, and increase the value and competitiveness of buildings. No wonder the demand for energy efficiency is accelerating rapidly. There are several examples where the existing buildings are retrofit with new energy-efficient solutions as well as adopting solar power. Even the green building movement has further given a boost to these initiatives.

performance of the building. All such areas that need energy optimisation are detailed out through studies that also focus on the need for technology upgrade and automation.”

Criteria of an energy-efficient building Energy Performance Index (EPI) is the first parameter to assess the energy performance of a building. The lower the EPI, the more efficient the building is. According to Saurabh Kumar, Managing Director, Energy Efficiency Services Ltd., “The buildings’ EPI assessment coupled with a quick assessment of the equipment in use, done through a walk through to ascertain possible areas of higher energy consumption or energy wastages, together leads to assessment on the energy

Rumi also adds, “Equipment level as well as system level energy efficiency need to be worked out and compare with the design efficiency which will help determining the energy-efficiency performance of the building.”

Even Rumi P Engineer, Head - Green Building Consultancy Services and Energy Conservation, Godrej & Boyce Mfg. Co. Ltd., thinks the same.

He says, “In order to judge whether a building is energy efficient or not, one needs to have sub-system level energy data, map the trend, and work out the Energy Performance Index (EPI) as per the BEE norms.”

consumption usually occur during the design process. “Design of an energy-efficient building needs to be done from the point of view of optimal life cycle costs, not the first cost,” says Saurabh Kumar, Managing Director, Energy Efficiency Services Ltd. “Many aspects of a building’s performance depend

Rumi P Engineer, Head - Green Building Consultancy Services and Energy Conservation, Godrej & Boyce Mfg. Co. Ltd.

Equipment level as well as system level energy efficiency need to be worked out and compare with the design efficiency.

Cover Story II Energy Efficiency on design stage interventions. Space cooling requirements can be reduced to nearly half through judicious orientation of the building, ensuring maximum natural ventilation, use of shades, insulation and high U-value glass for windows and doors. Use of artificial lighting can also be mitigated through use of natural lighting through high U-value windows, glazed films and sun roofs.”

According to Rohit Mahajan, Head of Design, Emaar MGF Land Ltd., “A most cost-effective energy efficient solution can be achieved if it is made an integral part of the design basis starting from the project. Appropriate passive architecture techniques, sun path analysis, orientation, and climatic responsive envelope design are measures which can contribute to a great extent if applied at the right stage.”

However, Rumi thinks there is nothing as perfect design for energy efficiency. “It is contextual,” he remarks. “One has to understand the end-use application of the building and appropriate design needs to be worked out. Design stage is the very crucial to build in energy efficiency in the project.

It is an integrated approach, wherein all the stakeholders (client, architect, MEP design consultant, PMC) play important roles in aligning the design inputs.”

‘Energy harvest’ vs ‘energy conservation’ Energy conservation is reduction in end-use energy, whereas energy harvesting is making use of natural resource for end use energy.

“Energy conservation and energy harvest both goes hand-in-hand,” remarks M. Anand,

Saurabh Kumar, Managing Director, Energy Efficiency Services Ltd.

Design of an energy-efficient building needs to be done from the point of view of optimal life cycle costs, not the first cost.

Principal Counsellor, CII-IGBC. “Energy conservation is about consuming or utilising energy in an efficient way and energy harvest is about generating renewable energy.”

According to Mahajan, both have their own significance. He says, “Energy conservation is foremost with the aim being to reduce the per capita energy consumption. Energy conservation can be achieved by using it with care and efficient technologies. Energy harvest is the only solution to meet the future energy needs.”

Passive solar buildings There has been a tremendous change in the energy consumption pattern of buildings across the world. Since the 1980s, passive solar building design and passive house have demonstrated heating energy consumption reductions of 70-90 per cent in many locations.

Not only a robust building envelope design can go a long way in curtailing the heat gain in the building, it also substantially reduces energy demand of air-conditioning system — be it commercial or residential project.

However, passive solar building isn’t a new concept in India. “The design of passive solar building is deep rooted in our history,” shares Mahajan. “Our ancestors were mastered in the art of passive solar architecture. We are adopting our old-age techniques for designing modern buildings with an amalgamation of new innovations in technologies.”

Even Anand confirms that the concepts of passive solar building design were practiced since long back, even before the advent of mechanical heating and cooling. He shares, “It remained as a traditional part of vernacular architecture. In third century BC, during Indus Valley Civilisation, a lot of evidences demonstrate that they have considered factors such as solar orientation, thermal mass and ventilation while designing the residences.”

Challenges to develop energy-efficient buildings Achieving energy efficiency in building poses several challenges. “The major challenge in building a highly energy-efficient building is the reluctance of client to spend the additional set-up cost,” says Architect Surinder Bahga.

“Another challenge is the bye-laws and nonavailability of proper trained and aware workmanship.”

M. Anand, Principal Counsellor, CII-IGBC

Energy conservation is about consuming or utilising energy in an efficient way and energy harvest is about generating renewable energy.

According to Kumar, “There are broadly two reasons for the slow adoption of energy efficiency in our country: technical and financial. In a scenario where multiple functions compete with one another for financial allocation, the financial resources available with building managers to undertake energy-efficient projects are rather limited mostly due to the fact that such investments often payback in a time frame not commensurate with the financial planning.

IGBC, BEE and EESL are all working to turn around these impediments. With Green Building Rating System, IGBC is helping buildings sustain energy-efficient practices over the life of a building. BEE is working towards incorporation of energy-efficiency parameters in the building bye-laws and building stakeholders’ capacity by training architects on ECBC, certifications and other relevant trainings, whereas EESL has been doing projects on ESCO mode that circumvent the need for first cost to finance energy-efficient projects that payback using the accrued energy cost savings.

Sustainability and energy efficiency are the 21st century buzzword. We only need to educate the market about the benefits of energy-efficient buildings. Once the technology and material are locally available and pricing become competitive, energy-efficient buildings will be widely accepted. n

Systemic approach towards energy conservation “We have been able to help our clients in managing their investment at various stages in the project, advising right from the conceptual design stage till the hand over of the project stage,” remarks Rumi P Engineer, Head – Green Building Consultancy Services and Energy Conservation, Godrej & Boyce Mfg.

In an exclusive interview with ACE Update, Rumi P Engineer — who has been involved in more than 400 green building projects — talks about his passion on energy-efficient buildings.

Judging energy-efficiency performance In order to judge whether a building is energy efficient or not, one needs to have sub-system level energy data, map the trend, and work out the Energy Performance Index (EPI) as per the BEE norms. Equipment level as well as system level energy efficiency need to be worked out and compare with the design efficiency which will help determining the energy-efficiency performance of the building.

is reduction in end-use energy. ‘Energy harvesting’ is making use of natural resource for end use energy, e.g. daylight harvesting, solar photo voltaic energy harvesting, converting waste to biogas, among others.

Energy harvesting has remained challenging which requires technical intervention as well as investment. Comparatively energy conservation is simple to implement wherein low cost/no cost energy saving potentials can be identified in the operations and maintenance practice in the building. There are plenty of opportunities available to implement energy conservation.

Passive solar buildings A robust building envelope design can go a long way in curtailing the heat gain in the building, resulting in substantial reduction in energy demand of air-conditioning system — be it commercial or residential project. In recent past, most of the projects have experienced positive result and understood the merits of the same, hence energy simulation at the design stage helps architects and MEP design professionals understand the energy end use which leads to informative decision making process in selection of material like glass, insulation, and energy efficient chillers, and pumps.

Challenges to build energy efficient buildings Challenges are plenty but at the same time manageable. Energy-efficient build environment commences from the conceptual

design stage where in passive architecture, building envelope, selection of material exhibiting good thermal properties, highefficiency chillers, fans, blowers, pumps, and integration with building management system needs to be integrated.

One also needs to understand the building end use and then select appropriate technology and equipment to suit the requirement.

Godrej & Boyce and energy-efficient buildings Godrej & Boyce is assisting its clients in green design, energy simulation, lighting simulation, BIM, testing adjusting and balancing of system at the commissioning stage and energy end-use assessment post occupancy. The organisation also undertakes retro-commissioning assignments.

Godrej & Boyce selects the best equipment and technology for a project, though selection alone does not ensure energy efficiency in the project because a lot of equipment forms a ‘system’. Hence it requires a ‘systemic approach’ for integrating all the equipment to ensure the performance and have positive results towards energy conservation.

enhanced productivity, thereby leading to substantial national benefits.

Further, Green Building Rating System brings together a host of sustainable practices and solutions to reduce the environmental impacts. Green building design provides an integrated approach considering life-cycle impacts of the resources used.

IGBC Green Building Rating Systems for India, which were launched in 2007, received overwhelming response from the construction industry. These have become National by choice and Global in performance and are widely accepted by all the stakeholders.

All the rating systems of IGBC are voluntary, consensus based, and market-driven building programmes and based on the five elements of the nature (panchabhutas) — a perfect blend of ancient architectural practices and modern technological innovations.

IGBC Rating Systems has been developed based on the contemporary materials and technologies and evaluates certain credit

Interview II Energy Efficiency points, using a prescriptive approach and other credits on a performance-based approach. The rating system is evolved as to be comprehensive as well as user-friendly.

Today, IGBC is on its own and has fully indigenised all its green building rating systems. The council is well poised to shape Indian construction the green way and develop world-class green building standards and practices.

What are the criteria on which one should judge whether a building is green or not?

The concept of ‘green building’ is primarily based on principle of sustainability. A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building.

It stimulates sustainable practices in design stage, construction stage, followed by operations and maintenance stage. Various imperative aspects associated with green building are sustainable site planning, climate responsive building design, indoor air quality, water efficiency, energy efficiency, eco-friendly commuting practices, managing construction waste, waste segregation at source and effective use of natural resources.

A green building yields significant tangible and intangible benefits which enhances the overall building performance and increases productivity of its occupants.

consumption reductions of 70-90 per cent in many locations. Where does India stand in designing passive solar buildings?

In India, the availability of sun is abundant.

Thus, the concepts of passive solar building design were practiced since long back, even before the advent of mechanical heating and cooling. It remained as a traditional part of vernacular architecture. In third century BC, during Indus Valley Civilisation, a lot of evidences demonstrate that they have considered factors such as solar orientation, thermal mass and ventilation while designing the residences.

The modern green buildings are continuing to use the solar passive building traditions through the use of solar passive interventions such as light/sun pipes, wind towers, solar air conditioning, radiant cooling, and phase change materials, among others.

Some of the contemporary projects that have extensively used these concepts are Avani Residence in Hyderabad, Suzlon One Earth in Pune, Turbo Energy Ltd. in Chennai, Eicher Corporate Office in Gurgaon, and Gujarat Pollution Control Board in Gandhinagar, to

Benefits of IGBC Green Building Rating System • Energy savings to the tune of 4050% • Water savings to the tune of 20-30% • Intangible benefits like enhanced ventilation and better views and day lighting which significantly improves the productivity of the occupants/ residents • Enables health and well-being • Promotes native species • Enhances biodiversity • Effective waste management

name a few.

What’s your opinion on the “energy harvest” versus “energy conservation” debate?

Energy conservation and energy harvest both goes hand-in-hand. Energy conservation is about ‘consuming or utilising energy in an efficient way’ and energy harvest is about ‘generating renewable energy’.

The designers should first focus on utilising

Avani Residence, Hyderabad

Most cost-effective steps towards a reduction in a building’s energy consumption usually occur during the design process. What should be the perfect design of an energy-efficient building?

The most cost-effective way to reduce the energy consumption is to design a building in a climate responsive way. Basic elements of climate responsive building are orientation of the spaces based on the functionality, size and placement of openings based on the function and climate, appropriate selection of energy-efficient materials and equipment.

Incorporating appropriate strategies in the design stage, the energy savings potential would be about 40-50 per cent.

Energy Efficiency II Interview structures. IGBC endeavours to take onboard all the stakeholders, including the young minds and professionals. We have taken several measures to promote or develop green buildings in India.

IGBC is developing Green Building Rating Systems to suit various types of buildings.

Till date, IGBC has launched rating system for schools, mass rapid transit system, new buildings, existing buildings, homes, commercial buildings, landscape, SEZs, townships and factory buildings. All types of buildings across the country are going the green way.

the available energy in an efficient way through use of energy-efficient lighting fixtures, HVAC systems, and appliances, then explore the possibility of using renewable energy systems such as solar, wind or hybrid systems to further reduce the energy demand for the green building.

What are the challenges to build of a highly energy-efficient building, and how can we overcome them?

Achieving energy efficiency in building poses number of challenges but at the same time presents a host of opportunities.

First is awareness and training.

Incorporating energy efficiency measures at design stage requires knowledge of green building concepts. There is now a need for skilled, knowledgeable professionals who have deep understanding of architecture and energy systems. Energy simulation programmes are excellent tools to design energy-efficient buildings. IGBC with the support of all the stakeholders is facilitating training of professionals on these tools.

Second is availability of materials, equipment and technologies.

The availability and affordability of materials/ equipment which contribute to energy efficiency is another major challenge.

Tremendous potential exists for materials and equipment like heat resistive paints, fly ash blocks, insulation materials, highefficiency chillers, variable frequency drives, high-efficiency cooling towers, building management systems, lighting controls, BIPV (Building-Integrated Photovoltaics), and micro wind turbines, to name a few.

24

november 2014

In order to facilitate the spread of these products, IGBC has several platforms, including Green Building Congress, IGBC online directory on building materials, Green Technology Centre in CII-Godrej GBC and IGBC local chapter meetings.

With over 2 billion sq. feet of green building footprint, India is the second largest country with the green building footprint.

The projects spread across the five climatic zones of the country. IGBC aspires to cross 10 billion sq. feet by 2022.

Third is national codes and standards. The Government of India has launched the ‘Energy Conservation Building Code (ECBC)’, which is voluntary and applicable to buildings or building complexes that have a minimum connected load of 100 kW or a contract demand of 120 kVA, whichever is greater. This code addresses the minimum performance standards for energy efficiency in a building, covering building envelope, HVAC systems, service hot water and pumping, lighting systems, electrical power and motors. This is an excellent initiative which will enable design of high-performance buildings.

IGBC has 16 local chapters, which reach out green building concepts at the state and regional levels. To meet the local aspirations, we have launched local chapters in different parts of the country.

Finally, a building can have the best of materials, equipment and systems in place at the design stage. However, the building can sustain the savings only if it is monitored on a continuous basis. Proper measurement and verification of savings will help the building owner to fine-tune the base line and achieve high level of savings.

Applying rating programmes like IGBC EB O&M (IGBC rating for existing buildings) can help buildings to sustain energy-efficient practices over the life of a building.

How is IGBC playing its role in promoting or developing green buildings in India?

Then we have more than 40 students chapters, which instil a sense of commitment towards planet earth and encourage the student members to adopt the greener way.

IGBC also forges vibrant partnerships with various national and international organisations in exploring new areas of cooperation and business opportunities. Our recent MoUs include MoU with NHB, CREDAI, Energy Efficiency Services Ltd., European Solar Shading Organisation, University of Salford, IAPMO, ASHRAE India, ISHRAE and IPA. IGBC also regularly organises “paint our earth- drawing competition for school children” aiming to generate awareness amongst school children, on the need and importance of environmental protection.

With the support and cooperation of all stakeholders, IGBC regularly organises various outreach programmes includes Green Building Congress, green building missions, training/awareness programmes and exhibitions. IGBC has trained over 20,000 professionals on green building rating systems, concepts and technologies. n

Energy saving achieved through compromising indoor thermal comfort is not counted as we are saving energy at the cost of occupants’ discomfort.

Reducing building’s energy consumption It is always better to focus on energy efficiency at design stage to make it more economical. Certain steps to be followed are: • Perform energy modelling, sun path analysis, shading analysis, daylight analysis to select building materials and MEP equipment based on the life cycles costing or total owning cost • Place building in north-south orientation to minimise heat gain • More glazing on the north façade to cool the day light • Keep window to wall ratio in the range of 20-30 per cent • Shading to minimise heat ingress and

‘Energy harvest’ vs ‘energy conservation’ Energy harvesting is the best way to minimise energy consumption for the building and make the power available free of cost for the entire life of the building.

At present, the payback period is more than 7 years for any renewable energy sources, which are the best way to overcome current power crisis in the country as well as help building occupants not to depend of the grid power for at least critical loads to perform their task. This is focus area for current government to overcome current power shortage issues. This field is expected to grow with the government support to make renewable sources economically viable for clients to adopt in the near future. At present, companies are focusing more on energy conservation when compared to harvesting energy due to less attractive payback and also space constraints in the urban buildings.

India and passive solar buildings In 1980s IT revolutions were just begun to hit our country, and small predominantly buildings are mostly non AC type. Hence more focus was given for passive design and optimised energy resources through minimum heat gain and with maximum natural lighting. Now developments are in huge scale and mostly with AC system as we occupy multi-storey buildings in a tight

site and dense surroundings. Nowadays, AC systems are mandatory to occupy and operate tight buildings. In modern buildings, passive features are also part of the design and not feasible to reach 70-80 per cent savings as our active component are predominant in the building from heating, cooling, lighting, data centres, equipment, computers, white goods, kitchen equipment, among others. These equipment increases energy load and hence reaching 30-40 per cent energy savings are recognised as outstanding results with adoption of modern technologies.

Overcoming challenges Challenges are multifold. Here is a list with few of the critical challenges and broad strategies to overcome: • Green should be part of design • Design consultant should give equal importance to building performance besides aesthetics • Need to have more and more energyefficient equipment manufacturing here in India, rather than depending on imports. This will certainly reduces project cost • Focus should be given for life-cycle cost • Need to have proper mandatory energy performance standards and legislation to prevent in building in-efficient building in this country • Design consultants fee should be performance-based fee from current scenario of fixed fee.

Promoting energy-efficient buildings LEAD Consultancy is playing pioneering role in the country by training professionals to design energy-efficient buildings, performing design and simulations to develop energy-efficient buildings for major corporate and builders. LEAD is also working with several technology providers to improve equipment efficiency through continuous interaction. The firm has completed more than 80 green certified building ranging from 10 per cent energy savings to as high as 50 per cent savings.

The firm is also working with more than 100 buildings across the country for making energy-efficient buildings. All these buildings designed with high-end energy technologies and deployed technologies is based on the life-cycle analysis. n

lass helps in reducing the need for artificial lighting, minimising the energy consumption. Green buildings admittedly cost more to build but the operational cost is substantially reduced.

In an interview with ACE Update, Vikram Khanna shares why glass is an effective green building material.

What role do glass products play in energy efficiency of a building?

Glass has become an integral part of modern day architecture. It not only gives the designers the choice of finish and a manifestation to their design aspirations but also a wonderful chance to participate with the outside world.

Glass ensures that the building gets ample natural light, making interiors look brighter and livelier reducing the need for artificial lighting and saving energy, or in other words, reducing the electricity bill.

These energy-efficient glasses provide the benefit of reducing the heat gain in buildings due to its excellent energy-saving properties without compromising on the natural light coming inside the building or the brilliant aesthetics that add value to the façade. And in winter, they ensure heat is not lost. Using energy-efficient glass also helps in ensuring that the interiors and the occupants of the home feel more comfortable. Performance parameters of glasses like visual light transmission, solar factor, U-value and internal reflection make buildings more efficient and ecologically viable.

Energy-efficient glasses, when used properly can reduce the total energy consumption

28

november 2014

by anywhere between 8-10 per cent of the total energy consumed, hence the accrued benefits of using these glasses keep growing over the years.

Is the awareness about energy-efficiency gaining traction among the end-users in India?

In recent times, the idea of green buildings has gained momentum. Builders, developers and architects are increasingly looking to make use of green materials like glass to add a new dimension to their buildings.

Awareness of environmental impact of increased construction activity has recently been on the agenda of governmental entities and environment ministry. It is widely expected that building code changes are in pipeline in order to adhere to these concerns. Construction houses are striving to obtain sustainability certifications, ensure a better quality of life for residents, and help conserve the environment.

How is the current demand for glass products in this segment?

Considering the characteristics of glass, it is being extensively used in today’s buildings.

Glass helps in reducing the need for artificial lighting and thereby minimising the energy consumption. Green buildings admittedly cost more to build but the operational cost is substantially reduced. This makes the cost of ownership of green buildings substantially less than conventional spaces. Various types of glazing solutions – both internal as well as external – have not only made our spaces more efficient but also unlocked new possibilities in design and aesthetics.

that are essential to design and build an energy-efficient building? What make them the ‘essential’ products for energy efficient buildings?

AIS has been at the forefront of this move towards an eco-friendly future. It has pioneered innovations in glass processing technology to develop products that feature the best ‘green’ parameters. AIS manufactures both single-glazed and doubleglazed products, allowing architects greater choice and the ability to explore newer possibilities. These solutions enhance the aesthetics and efficiency of commercial and residential spaces, and present builders with viable, attractive and economical alternative to traditional building materials.

Energy-efficient glass ranges from AIS, under the brand name of Ecosense, provides the benefit of reducing the heat gain in buildings due to its excellent energy-saving properties without compromising on the natural light coming inside the building or the brilliant aesthetics that add value to the façade. And in winter, they ensure solar gain. No matter what the season, people inside stay comfortable at all times. Using energy-efficient glass also helps in ensuring that the interiors and the occupants of the home feel more comfortable.

Ecosense comes in three ranges: Enhance (solar control), Exceed (solar control low-E) and Essence (low-E) high-performance glasses. Ecosense, ideal for solar and thermal insulating parameters, combines aesthetics with environmental sensibility and conforms to all international and national green standards, making it the natural choice as a green building solution. n

ontrolling increasing energy costs without compromising business performance is always a challenge.

In a conversation with ACE Update, Thanik B shares how Schneider Electric helps in striking the critical balance between active energy efficiency and smart facilities for customers.

Why is using ‘integrated energy management solution’ critical for the sustainability of a building?

Putting in place a robust integrated energy management and information system is the first step in any energy management program. It helps sets a baseline for KPIs at different levels within the organization and helps track them effectively which is the key for sustainable buildings. Such a system also provides a ready-to-use framework for the implementation of global energy management standards like ISO 50001 and facilitates the pursuit of green building labels such as like LEED and GRIHA. It also highlights the importance of putting a submetering infrastructure for load segregation as the starting point for best practices in energy management and effective interventions.

Is the awareness about energy efficiency gaining traction among the end-users in India?

Yes, definitely. The demand for energy efficiency is accelerating rapidly. These include regulatory pressures, shareholder and public demands for socially sustainable business practices, and increasing demand for energy and rising energy prices. Green directives like net-zero energy regulations in Europe, CRC Energy Efficiency Scheme in the

30

UK, and GRIHA rating system in India are driving major change.

New buildings standards and certifications like ISO 50001 and the shift of LEED and BREEAM (Building Research Establishment Environmental Assessment Methodology) to include certifications for operational performance of existing buildings are also having a significant impact on the built environment.

What makes your solutions the ‘essential’ solutions for energy efficient buildings?

Our response to today’s energy challenge is EcoStruxure, an active energy management architecture from Power Plant to Plug.

EcoStruxure is not a product but an approach that creates intelligent energy management systems. EcoStruxure system architecture allows one to see, measure, and manage energy use across data centres, industrial plants, buildings, and energy and infrastructure with guaranteed compatibility among critical energy domains.

In a conversation with ACE Update, Rohit Mahajan shares how Emaar MGF is working towards a sustainable, eco-friendly realty.

Judging energy-efficient building Energy efficiency in a building should be judged both at the operational and construction stage of the project. During the construction stage, the impact on air and water quality, neighbouring developments and microclimate should be minimum. The construction waste should be appropriately recycled and embodied energy of the materials used should be minimum. During the operational phase, the energy consumption in cooling and heating of the building and lighting load should be optimised. The use of potable water should be less for irrigation, and AC water makeup and innovative waste water technologies should be adopted. The heat island effect and light pollution should be minimised. A measurement and verification strategy should be in place, and the building energy consumption should be monitored against the predicted performance.

Perfect design of energy-efficient buildings A most cost-effective energy efficient solution can be achieved if it is made an integral part of the design basis starting from the project.

Appropriate passive architecture techniques, sun path analysis, orientation, and climatic

responsive envelope design are measures which can contribute to a great extent if applied at the right stage. However, all these measures may not be feasible for all type of projects with varied business needs.

At the other end, we can integrate energyefficient MEP systems and automation which has higher capital investment but eventually pay off during the operational stage.

‘Energy harvest’ vs ‘energy conservation’ Both have their own significance. Energy conservation is foremost with the aim being to reduce the per capita energy consumption. Energy conservation can be achieved by using it with care and efficient technologies. It requires coherent efforts from all stakeholders – end users, developers, manufacturers and government.

Energy harvest is the only solution to meet the future energy needs. However, more research and initiative are required from the government to make solar, wind, and tidal energy a reality which at present doesn’t seem feasible for individual projects because of geographical constraints, expensive real state, technical challenges and high cost.

Passive solar buildings The design of passive solar building is deep rooted in our history. Our ancestors were mastered in the art of passive solar architecture. We are adopting our old-age techniques for designing modern buildings with an amalgamation of new innovations in technologies.

Sustainable India is possible

“Vision of smart cities in India by Prime Minister Narendra Modi can be achieved through energy efficient and green building developments,” believes Mala Singh, CMD, PEC Greening India Group

P

EC Greening India Group plays a huge contributory role in achieving energy efficiency in buildings. The group also spreads awareness regarding energy efficient and green buildings through builder orientation programs, PMC and labour workshops, conferences, seminars and also through mass media publications to reach out to the common man. In a conversation with ACE Update, Mala Singh shares why the dream of sustainable India can come true.

Energy-efficient criteria For a building to be energy efficient, it needs to achieve its proficiency in the many ways. The focus is the systems and technologies used in the building which uses ample amount of electricity. To reduce energy consumption, adoption of energyefficient, sustainable technologies helps save electricity cost. The systems responsible for overall energy consumption are airconditioning system, heating and cooling system, lighting system, building envelope design, and other miscellaneous equipment used for various purposes.

HVAC system accounts for a major portion in the building’s energy consumption as it regulates the indoor environmental

34

november 2014

factors such as temperature, humidity, and air quality. The influence of HVAC system upon energy consumption may vary for buildings depending upon the nature and typology of the building. For instance, in centrally air-conditioned buildings which are often energy guzzlers, an intelligent HVAC system with zone wise controls will help reducing the overall energy consumption, especially a system which is designed with world-class standards or nationally applicable standards. In buildings with unitary air-conditioning systems, star-rated air conditioners assure energy efficiency.

An energy-efficient lighting design is highly beneficial for any building. Maximum use of daylight integrated with an efficient artificial lighting layout and energy-efficient lighting fixtures like LED and CFL are highly beneficial to achieve energy efficiency at a larger level. Incorporation of lighting controls like occupancy sensors and daylight sensors help increase the proficiency of the lighting system to save the overall energy cost.

An optimised building envelope or in other words, a smart and intelligent/climate responsive design can help determine the amount of lighting, heating, and cooling a

building will require. Energy-efficient roof and wall construction with proper thermal insulation, optimum window wall ratio, intelligent use of glass, and well-designed shading devices in building façade help maintain the desired heat gain/loss thereby reducing the overall energy requirement.

Passive strategies like proper building orientation, shading devices, courtyards, buffer spaces, evaporative cooling, and sun spaces also contribute to maintain comfort within building, thus reducing energy consumption. Use of star-rated energy efficient equipment and appliances also save huge amount of energy and electricity costs.

Incorporating solar water heating system, solar lighting for exterior, wind mills, and geothermal energy help in reducing the overall load upon conventional energy sources which finally helps a project save a huge amount of energy and electricity costs.

Perfect design of an energy efficient building For an energy-efficient building, incorporating climate responsive building design strategies in design stage itself is vital. By incorporating efficient measures in the design, the targeted building energy consumption can be lesser than the

Interview II Energy Efficiency standard energy requirements. A perfect design for an energy-efficient building begins with the analysis of the macro and micro-climatic conditions, including solar, wind, vegetation, soil, and water. Further on optimum active and passive strategies should be incorporated into the building design for harnessing the same at the site.

Passive strategies as per climate and site conditions like the building orientation, building envelope, shading devices, window wall ratio, natural ventilation, daylight, evaporative cooling, earth tube cooling, and sun spaces are cost-effective steps to reduce the building energy demand and consumption.

Active systems like HVAC system, lighting systems, and equipment should be designed based on the reduced energy demand arising from passive strategies. Efficient HVAC systems based on their COP, lighting fixtures to achieve reduced LPD, and starrated equipment should be proposed in the project.

Incorporation of renewable energy systems, DG sets for power backup, building maintenance and automation systems to monitor the performance of energy systems help reduce overall energy consumption. The capital cost involved in these systems can be recovered through direct savings achieved.

‘Energy harvest’ vs ‘energy conservation’ There has been a long standing debate between energy harvest and energy conservation. While energy harvest focuses on harvesting renewable energy like solar, wind, thermal energy and storing into wireless autonomous devices, energy conservation moreover deals with strategies aimed at reducing the overall energy demand. There does not arise a need to choose one entity over the other as both energy harvesting and energy conservation measures if properly integrated in building will yield energy-efficient green buildings.

In a green building, various strategies like use of efficient HVAC system, use of efficient lighting, provision of user controls and optimum behaviour approach help in assuring energy conservation.

However, there may be shortcomings in the behavioural approach of building users which

can counteract by building automation and intelligent building systems. In such cases, controls like occupancy sensors and daylight sensors become useful, which help in assuring minimal energy wastage and optimal use. Such controls, if integrated with energy harvesting through renewable energy resources, will create intelligent control devices like sensor network systems.

This will definitely result in the creation of smart and intelligent green buildings.

Designing passive solar buildings Passive solar building design incorporates natural energy sources and sinks, e.g. solar radiation, outside air, wet surfaces, and landscape, depending on the climate.

Indian architectural carries a rich heritage of passive solar buildings like forts, palaces, museums, government buildings, commercial buildings and residences based on the diverse climatic conditions. In the modern times, India has seen many developments in the green building sector like government policies, Energy Conservation Building Code, and IGBC and GRIHA rating systems. These are being effectively incorporated by many responsible stakeholders of the construction industry. There should be optimisation of human behaviour approach along with effective operation and maintenance systems in buildings to achieve and monitor the data bank of energy consumption reduction in the building, thereby helping reduce carbon footprints.

Challenges to develop energy efficient buildings Absence of green build mandate policy by the Government of India, lack of commitment towards green development by the developer (few developers have shown their passion till so far towards Green development), misconceptions about the additional cost of green buildings and its benefits, non-integration of green design strategies in planning by the project team, lack of awareness about green products and technologies and behavioural anomalies to adopt green, lack of skilled labour, and lack of adequate incentives for energy-efficient buildings are some of the challenges to build energy-efficient buildings.

PEC Greening and energy-efficient buildings PEC Greening India Group plays a huge

contributory role in achieving energy efficiency in buildings. The group has made energy efficiency one of its main aims when transforming its projects into green and responsible developments from the design stage itself by involving all the project consultants and developers.

It also spread awareness regarding energy efficient and green buildings through builder orientation programs, PMC and labour workshops, conferences, seminars and also through mass media publications to reach out to the common man.

Its New Paryavaran Bhavan in Gandhinagar is LEED Gold certified building. This building has incorporated courtyard architecture with proper fenestration design and recessed windows in design which is a key feature resulting in reduced energy consumption. But the highlight of this sustainable building is the provision of an 80kW grid connected solar power plant system on the terrace which helps make the building energy positive. This solar power system is directly connected online to the grid such that the generated power is used by the building with the surplus going to the grid which in turn gives monetary benefits to the owners.

In addition to that, the group is involved in transforming more than 91 million sq. feet of building footprint into green across the country, covering various categories of projects like residential, office buildings, schools, universities, hotels, malls, and ports. Its strong connectivity and inspiration process to all kind of stakeholders of the country including government organisations, private developers, various institutions and societies will not only help them in transforming India but also will set an example of making India a responsible country towards green at global level.

Mala Singh also sums up that Prime Minister Narendra Modi’s vision towards existing cities’ retrofitting and smart cities’ development can be only achieved if energy efficient and green buildings will be considered as a mandate for all kind of developments by the government.

Hence, the dream of sustainable India can come true. n

EESL facilitating energy-efficient projects “EESL is the only Energy Services Company (ESCO) in the country to implement energy-efficiency projects on investment sharing model,” says Saurabh Kumar, Managing Director, Energy Efficiency Services Ltd.

T

he concept of performance contracting implemented by Energy Service Companies (ESCOs) helps overcome some of the barriers hindering and discouraging the large-scale implementation of energy efficiency projects. In order to develop a viable ESCO industry, the Ministry of Power has set up Energy Efficiency Services Ltd. (EESL). In an exclusive interview with ACE Update, Saurabh Kumar talks about the importance of energy efficiency and how EESL is working to facilitate implementation of energy-efficient projects.

EESL is the first government ESCO in Asia.

What kind of services EESL is providing in the field of energy efficiency?

Energy Efficiency Services Ltd. (EESL) was set up through initiative of the Government of India through equal equity participation of four central public sector units under the Ministry of Power: NTPC, POWERGRID, PFC and REC. EESL — the implementing arm for energy efficiency in the country — has been working with central and state governments in various sectors to implement an institutional mechanism for implementation of energyefficiency projects. It is also leading the market related actions of the National Mission for Enhanced Energy Efficiency, one of the thrust areas under the eight missions envisioned under the prime minister’s National Action Plan for Climate Change (NAPCC).

What are the criteria on which one should judge whether a building is energy efficient or not?

Measuring the energy performance index (kWh consumed annually per sq. metres) is the first parameter which can be used to assess the energy performance. The lower the EPI, the more efficient the building is.

The buildings’ EPI assessment coupled with a quick assessment of the equipment in use, done through a walk through to ascertain possible areas of higher energy consumption or energy wastages, together leads to assessment on the energy performance of the building. All such areas that need energy optimisation are detailed out through studies that also focus on the need for technology upgrade and automation.

Most cost-effective steps toward a reduction in a building’s energy consumption usually occur during the design process. What should be the perfect design of an energy efficient building?

Design of an energy-efficient building needs to be done from the point of view of optimal life cycle costs, not the first cost.

Many aspects of a building’s performance depend on design stage interventions.

Space cooling requirements can be reduced to nearly half through judicious orientation of the building, ensuring maximum natural ventilation, use of shades, insulation and high U-value glass for windows and doors. Use of artificial lighting can also be mitigated through use of natural lighting through high U-value windows, glazed films and sun roofs. Use of star-rated appliances and automation through energy monitoring and control (EMC), sensors (stand alone or integrated) can further lead to greater cost

economics in designing an energy efficient building over the life cycle.

What are the challenges to build of a highly energy-efficient building, and how can we overcome them?

There are broadly two reasons for the slow adoption of energy efficiency in our country: technical and financial. There is a general incompetence amongst most building O&M managers to comprehend the technical advantage of investing in energy efficiency. In a competitive market where product technologies and their technical specifications tend to change rather frequently, the building managers have been found to be constrained in comprehending the apt solution and unsuccessful in demonstrating the business driver advantages for energy-efficient projects. Energy-efficient projects often fail due to lack of financing too. In a scenario where multiple functions compete with one another for financial allocation, the financial resources available with building managers to undertake energyefficient projects are rather limited mostly due to the fact that such investments often payback in a time frame not commensurate with the financial planning.

The BEE and EESL are committed in working together to turn around these impediments.

While BEE is working towards incorporation of energy efficiency parameters in the building bye-laws and building stakeholders’ capacity by training architects on ECBC, certifications and other relevant trainings, EESL has been doing projects on ESCO mode that circumvent the need for first cost to finance energyefficient projects that payback using the accrued energy cost savings. n

ith sustainability as its global focus, Grundfos ensures that all of its products are intelligent as well as energy efficient. Through its highefficiency pump and motor technology, Grundfos can reduce the average pump’s energy consumption by up to 60 per cent.

In an exclusive interview with ACE Update, Gangaprasad G shares what makes Grundfos standing tall in the competition.

Pumping products in energy efficiency buildings Pumps play a major role in the energy efficiency of a building. Buildings consume approximately 40 per cent of energy in which pumps consume about 12 per cent energy.

Nearly 30 per cent of energy consumption by pumps can be saved by installing energyefficient pumps. Grundfos provides the most energy-efficient pumping solutions with the lowest life cycle cost to its users. Its main products include circulator pumps for heating and air-conditioning as well as other centrifugal pumps for the industry, water supply, sewage and dosing.

Awareness about energy efficiency in India There is an increased awareness about energy efficiency at the end-user level, and it is gaining momentum. There are several examples where the existing buildings are retrofit with new energy-efficient solutions as well as adopting solar power. The Indian consumers are now more open to using energy-efficient products which not only help conserve energy but also lead to

38

significant savings. Both corporates and the consumers are slowly but steadily realizing the benefits of reviewing the life-cycle costs of eco-friendly products. The green building movement has further given a boost to these initiatives. People are increasingly adopting energy-efficient methods and solutions in their buildings and localities which is a positive sign.

Energy-efficient Grundfos products The demand for pumping solutions for commercial and domestic buildings is on the rise. Energy-efficient pumps are preferred at the time of purchase. In a typical building, pumps consume about 15 per cent of the energy in air-conditioned system. Hence energy-efficiency feature will be an added advantage for the pumps. Secondly, with space coming at a premium in most of the buildings, compact with higher specifications equipment are preferred by the customers.

Essential Grundfos products for energyefficient buildings Grundfos multi pump controller, which is an integral part of HVAC and hydro pneumatic systems, is very unique. It incorporates features that are aimed at energy optimisation which consequently reduces wastages. Grundfos sewage pumps have the patented S-tube impeller which is one of its kind with efficiency ranging upto 84 per cent. SQ Flex, unique and efficient solar pump from our product range is another solution which uses renewable energy ensuring energy efficiency.

Trends and opportunities in energy efficiency With energy consumption growing at an exponential pace, the Indian Government has undertaken several initiatives towards better energy management. The Bureau of Energy Efficiency (BEE) has developed the National Building Code as a guideline to be followed by development authorities in formulating and adopting byelaws. In fact, Grundfos has developed iSolutions aimed at providing a range of innovative and energyefficient solutions which bring down the cost of ownership.

Promoting energy-efficient buildings in India Grundfos promotes-energy efficient buildings through its energy-efficient products and services. With sustainability as its global focus, all Grundfos products are energy efficient and conserve energy.

Superior technology in its electrical and solar pumps ensures that its pumps are intelligent and will be in use only when it is necessary, conserving lot of power.

Through its high-efficiency pump and motor technology, Grundfos can reduce the average pump’s energy consumption by up to 60 per cent. Grundfos pumps have been known for energy efficiency and reliability.

While the pumps are produced to meet the tough working conditions of industry applications, utmost care is taken to comply with environmental norms in terms of recyclability of the pump components, usage of non-volatile paints, use of energy efficient motors, among others. n

Designing is key for energyefficient building “We always work cautiously to create energyefficient, climate responsive buildings,” says Architect Surinder Bahga

A

rchitect Surinder Bahga is a name synonymous with energy-efficient buildings and has worked for developing the green building code for Punjab.

He is actively spreading awareness among the budding architects through seminars and conferences. In a conversation with ACE Update, Ar. Bahga shares why energy-efficient building is the future.

Judging energy-efficient building In today’s scenario of energy crisis, a building can be judged based on its energy usage, i.e. whether the building is in conformity with nature or against it. A building can be energy efficient if the operational cost of that building is minimum and the natural resource utilisation is maximum.

Designing energy-efficient buildings Designing is the key to achieve an energyefficient building. While designing a building, a lot of things are to be kept in mind. One such major factor is the climatic condition of the site. Indian subcontinent is broadly divided into five climatic zones: composite, hot and dry, warm and humid, moderate and cold, and cloudy climate. Each climatic zone has its own design considerations. For example, in warm and humid climate, maximum ventilation is provided. Even shaded and covered openings are considered to minimise load on air conditioning, whereas it’s opposite in case of cold and cloudy climate where clear windows and barriers for wind flow are a must.

‘Energy harvest’ vs ‘energy conservation’ Energy harvest is the process of accumulating

40

november 2014

energy from sources like sun, wind and water, whereas energy conservation is utilising energy efficiently in the building. An energyefficient building needs to incorporate these both aspects side by side so as to minimise the wastage of energy.

Going green There has been a tremendous change in the energy consumption pattern of buildings across the world. A lot of awareness is being created by various agencies regarding green and energy-efficient structures. In India agencies like BEE, IGBC and GRIHA are constantly working in this field, and it is due to these efforts that today India has more than 2 billion sq. feet of green building footprint.

Challenges to design energy-efficient buildings The major challenge in building a highly energy-efficient building is the reluctance of client to spend the additional set-up cost. Another challenge is the bye-laws and non-availability of proper trained and aware workmanship. This can be reduced by spreading awareness which should not be limited to architects or clients but also to contractors and workmen.

Saakaar and energy-efficient buildings Saakaar Foundation always works cautiously to create energy-efficient, climate responsive buildings.

Industry issues addressed

Initiatives taken by Kohinoor Hospital

Issue 1: Hospitals are guzzlers of energy due to 24/7 operations of highend biomedical, engineering and other equipment, thereby inflating energy cost.

Energy efficiency measures planned from project stage. example solar panels, use of natural lighting, motion sensors, VFDs for AHU and cooling towers, high COP energy-efficient chillers, and LED lights.

Issue 2: Increased carbon footprint of hospital industry.

Recycled material used for construction Recycling: sewage and water treatment plant Use of R-134A refrigerant which is free of HCFC and halons Low VOC (Volatile Organic Compound) material

Issue 3: Increased cost of health care

Initiative would bring operational efficiency in terms of electricity savings which are passed on to patients in terms of affordable tariffs/ health-care costs compared to similar hospitals with similar expertise and infrastructure.

Kohinoor Hospital has been also designed to save water in a variety of ways. The hospital also uses dual flush toilets and low-flow faucets to reduce water consumption. These water conservation measures save over 2.5 million gallons of water a year. Also, rainwater is allowed to filter into the ground gradually. This naturally filters the surrounding vegetation and reduced water logging.

Ventilation The hospital has installed state-of-the-art demand control ventilation and variable air volume systems to keep indoor air quality in check.

The demand control ventilation system uses sensors to monitor the quality of air and keep it fresh. VAVs have high-end sensors to provide the right quantity of cool air required for specific building zones. In order to prevent an urban heat island effect, where a particular area becomes hotter than its surroundings, solar energy pavers and panels have been used.

Natural light The hospital is built with an emphasis on getting natural lights in all the patient areas, which reduces the consumption of electricity. The large windows and open sky light keep the area cool and ventilated along with incoming natural light. It also used LED-emitted light to reduce heat on surgical field for increased patient safety and improve surgical team comfort.

End use

Energy consumption (x1,000 kWh)

Space cooling Recycling At Kohinoor Hospital, more than 40 per cent of the materials are recycled materials. The foundation of the overhead tank was built reusing scrap material. Salvaged wood was reused for making frames which helped conserve trees.

Water efficiency The hospital also has initiatives for water recycling and conservation where the water efficiency mechanism is implemented and conserves more than 40 per cent of water. In this system, the waste water from various zones of the hospital is treated using disinfectants at sewage treatment plant. The water is then reused for flushing, cooling airconditioning towers and for horticulture. The hospital also has dual flushes and urinal sensors in place to control water flow.

S

omeone mentioned the other day, that the sun produces enough energy in one minute to power the whole planet for one year! Amazing! But what are we doing about it?

Why don’t we solarise the whole world? Why don’t we convert every energy seeking device into solar? Well we don’t do it because we don’t seem to be having adequate space to install solar panels all over the world. For example we can’t install solar panels on the ocean, and we can’t install solar panels on forests and we can’t install solar panels where there are buildings... but wait. Of course solar panels can be installed on buildings!

Really speaking this requires a philosophical change and some smart countries like Germany have already opted for it, thus solarising the entire electrical landscape of the country by installing 32 GW of solar power, the highest in the world.

The ideal situation would be when houses

generate their own solar power on their rooftops and feed the surplus generated power (when not being consumed) to the electric grid. Factories and industries generate solar power on their roofs for their own captive use, thus reducing load on the grid. Farmers run their own pumps using solar power. Streetlights run on their own solar panels. This would greatly reduce the load on the grid, enabling the grid to shift priority to other areas which cannot be run by solar power. And then we could have several MW level solar farms which would generate enough power to assist the local grid during low availability of power.

How then does a solar plant run? Well essentially, solar panels generate DC electricity.

A solar panel may generate anything from one Watt to 350 Watts depending on its size.

Similarly the voltage of the panel also varies from 0.4 Volts to 35 Volts per panel. Joined together in series and parallel combinations, they effectively generate a much larger

volume of power. This output is now fed into an inverter, whose function is to convert the DC input to AC output for commercial use.

Homes and industries are supplied power from power substations. These substations draw power from grid substations or super stations.

For example, a 1,000 MW hydel power plant would deliver power to a 440/220 KV super station (thus reducing the produced power from 440 KV to 220 KV), which would transmit power to three to four 220/132 KV 132 KV grid substations. These in turn would transmit power to several 132/33 KV substations. The 132/33 KV substations would step down power and transmit to several 33/11 KV power substations. These 33/11 KV substations are manned by the distribution utilities who would further transmit the power to homes and factories at 11 KV or at 33 KV. At homes (colonies) and factories, a small transformer would step-down the power to 440 V 3-phase supply which essentially means that each phase carries 230 volts of electricity.

Expert Column II Energy Efficiency Recall that our solar plant had by now converted the DC power to AC power through the inverters. This AC power is now stepped up to (say) 33 KV and transmitted to the 33/11 KV power substation which is manned by the distribution utility. Our solar power thus, now augments the grid power.

Balancing Construction Chemistry....

Such solar power plants are called grid connected solar power plants. In effect the power produced by the panels is consumed instantaneously by the grid and is not stored.

A shade different are off-grid solar plants. In areas where the national grid is non-existent, solar power which is generated in the day is stored in batteries. Once the batteries are fully charged, the excess power is converted from DC to AC using inverters and transmitted to the user through transmission lines or cables. At night, DC is drawn from the batteries by the inverter, which converts the DC into AC and supplies to the consumer. In the process, the batteries partially drain out. These batteries are again fully charged in a few early morning hours and the cycle goes on.

There is still a third variety called the hybrid solar plant. This kind of plant principally derives power from more than one renewable or nonrenewable sources. For instance, a plant could have a wind generator, a solar generator and a diesel generator, all clubbed into one. In this case, during daytime the solar plant would generate power. At night, when the sun is not around, wind would continue to generate power. In the event that wind too is absent a diesel generator would automatically switch on to take care of the load. Typically, such applications are used in grid deficient regions like islands and mountains.

The Ministry of New and Renewable Energy (MNRE) has taken several measures to ensure that these ideal situations are met, with the ambitious Jawaharlal Nehru National Solar Mission (JNNSM) aiming to generate 22 GW of solar power by 2020. More than 2,000 MW of solar installations under various schemes have already been commissioned by various solar power developers. The MNRE has recently announced phase II of the mission wherein another 2,000 MW of solar development work has been commenced.

Typically, solar developers use EPC (Engineering, Procurement and Construction) contractors to construct the solar plant. EPC contractors are supposed to be experts in this field. This notwithstanding, the solar developer needs to be very careful while selecting his EPC contractor for solar plants since this is a highly technical field and only players with good experience must be chosen.

Companies and houses must secure their future needs of power by opting for solar power, whatever the immediately visible costs may be. This will greatly help them in the future, when power from fossil fuels is going to be prohibitively expensive. n About the author: Col Ajay Reddy (Retd) is the Head of Operations at Premier Solar.

armland Rainwater Harvesting Systems (FLRHS), based in Karnataka, has been in the forefront in rainwater harvesting technologies for over a decade, with respect to both rooftop as well as groundwater recharge, through indigenous path breaking and self-reliant technology. The firm is the proud winner of two national and international award winning technologies, involving dual intensity filters to store and reutilise and injection V-wire technology to recharge groundwater source. Both these technologies have found a wide acceptance because of the increased success rate at the field level. The firm’s continued efforts in setting up the state-of-the-art R&D and hydraulic testing lab to achieve a breakthrough in inventing and manufacturing revolutionary filters both in design and function.

patterns have resulted in torrential down pours and rainfalls of very high intensity. These heavy duty dual intensity rainwater harvesting filters are so designed, keeping in mind the capture of rainfall loads varying from 5-75 mm/hour without affecting the efficiency of filter with an operating pressure of less than 0.06 kg/sq. cm. Hence, the filter can perform even under low roof areas. The design, stability and filter function efficiency is directly proportional to the intensity of rainfall. Different models of filters were set in place to capture rainwater from varied rooftops. This brought in affordability, to all cross sections of households and industry. All the filter models work on the principle of cohesion force of water molecules and centrifugal force of water.

RAINY is a first of its kind dual intensity rainwater harvesting filters with self-cleaning and auto flush out mechanism. RAINY is the result of over 10 years of continuing R&D by Farmland. The research team has studied the actual pattern of rainfall in both rural and urban India, considering parameters like intensity of rainfall, type of houses, roofing materials, inclination of roof, pipeline used for rainwater outlets, reutilisation, recharging of ground water, and tube well.

The filters are highly scientific in design and built to give a long, dependable service. The key point of this filter is the self-cleaning mechanism in eliminating the need of periodic maintenance. Careful selection of materials and stringent manufacturing controls, assures the customer a satisfactory performance as per the filter rating. All materials used in this technology are eco-friendly and recyclable. The technology has gained wide acceptance reaching out thousands of consumers, especially individual households, institutions, schools and colleges, hospitals, commercial buildings, corporate sectors, industries,

Rainwater Harvesting II Expert Column

With scarcity of water going deep, conserving water and managing all available optimum resources have become the prime importance

Rainwater harvesting: future saviour A

ccording to U.N. estimates, amount of water on the earth is about 1,400 million cubic kilometres, which is enough to cover the earth with the layer of 3,000-metre depth. The increasing water demand, drying natural resources due to over exploitation, and often failure of monsoon have further worsen the situation, making the water a scare resource. However, the fresh water constitutes a very small portion of this enormous quantity. Only 0.3 per cent of the total water available on the earth is fresh water and the remaining is saline water in oceans. About 75.20 per cent of available fresh water lies frozen at Polar regions and another 22.60 per cent is present as ground water (50 per cent of which is available within extractable depth). The rest is available in lakes, rivers and moisture in atmosphere, soil and vegetation.

Need of rainwater harvesting Rainwater harvesting consists of a range of simplest, indigenous technologies, practised in India for centuries to collect, store and provide water. Nature replenishes the groundwater resource annually through seasonal rainfall, by way of infiltration through soil layers.

48

november 2014

Due to urbanisation, the soil surface exposed to the recharge is drastically reduced and therefore natural recharge is diminished.

Groundwater as a natural resource has the major benefit in meeting emergency supplies during the water scarcity periods. In order to maintain the groundwater resource potential, a hydraulic equilibrium must be maintained between the availability and utilisation. Today availability of water has put a serious question mark in front of everybody, so it is today’s need to conserve the water and manage all available optimum resources. Hence, there is immediate need for strengthening of existing water resources by harvesting with rain and treatment of wastewater, recycling and reusing of water.

Advantages of rain water harvesting • It provides self-sufficiency to one’s water supply • It reduces the cost of pumping of ground water as it increases ground water level • It provides high-quality soft water, low in minerals • It improves the quality of groundwater through dilution when recharged to ground • It reduces soil erosion in urban areas

• The roof top rainwater harvesting is less expensive • Rainwater harvesting systems are simple which individuals can adopt • Rain water harvesting systems are easy to construct, operate and maintain • In hilly terrains, rainwater harvesting is preferred • In saline or coastal areas, rainwater provides good quality water. When recharged to ground water, it reduces salinity and helps in maintaining balance among the fresh saline water interfaces.

Suitability of rainwater for drinking purpose Contrary to popular belief, water quality improves over time during storage in the tank due to sedimentation, floatation and bacterial die-off, if the water is not disturbed. Even pathogenic (harmful) organisms gradually die out during storage. The main factors for the bacterial decline are: • Algae die due to lack of sunlight • Competition for food increases • Predation increases reducing the prey micro-organisms and ultimately starving out the predators • Removal of some bacteria due to 49

urotek Environmental Pvt. Ltd., based in Vadodara, specialises in promoting innovative technologies in water and wastewater management. EEPL is also providing a range of solutions based on the best technologies which includes various laboratory instruments and equipment. EEPL has full-fledged service centres across India with factory trained service engineers. Eurotek also partners with several global renowned companies like Aeration and Ekoton.

Aire-O2 Triton process aerator and mixer Tritons are considered as “process” aerator due to its patented dual functionality which improves the oxygen transfer (1.83 KgO2/KwH) along with its excellent mixing ability (1ft/sec). This feature also offers the process benefit for biological nutrient removal (BNR) with a single unit, i.e. control of nitrification (aeration and mixing) and de-nitrification (only mixing) in separate on/off modes.

Strengths • EPA defined ‘fine bubble’ Aeration, 2.2 mm or less • Deep mixing capability up to 10 metres which ensures smaller footprint • Low speed (900 rpm/60 Hz – 750 rpm/50 Hz) operation ensures extended aerator life, improves mixing. Availability in 5 to 75 HP sizes • Power conservation is almost 40-50 per cent when compared to

48

other aeration • Requires no gear box and has very few wear parts • Certified as eco-friendly with no splashing and lesser noise level (60db) • Tritons are also compatible for DO based automation.

Aeration is providing advanced aeration system and other technologies such as customised oxidation ovals (tri-ovals), packaged plants, DAF systems, and sequencing batch reactor.

Application areas CETPs, ETPs, STPs, textile, chemical, dairy, pharma, pulp and paper, sugar, petrochemical, ponds, and lakes, among others.

Ekoton, Ukraine. (Wastewater Treatment Equipment) Ekoton provides a suit of wastewater treatment equipment.

• Equipment for biological treatment: aeration system and radial sludge removers for secondary clarifier • Equipment for mechanical treatment: screens, in-channel grinders, grit chambers, radial sludge removers for primary clarifier • Equipment for sludge dewatering: belt filter (presses and thickeners), screw dehydrators • Ancillary equipment: horizontal and inclined conveyors, compacting presses for screenings, grinders of screening, slide gates. n

f

flocculation and sedimentation • Biological contamination can be further removed by disinfecting the water.

Approach of municipal bodies towards rainwater harvesting Nowadays many municipal corporations are taking initiative in rainwater harvesting — not only by making it mandatory but also by encouraging citizens by various incentives such as exemption in property taxes. However, following areas need more attention for effective implementation of rainwater harvesting: • Proper governing body (dedicated departments) in order to audit the efficacy of executed rainwater harvesting projects • Single window and transparent solution for offering incentives, handling documentation for individuals and corporate who want to take initiative in rainwater harvesting • Effective governance to keep an eye on individuals or institutions who are not confirming to RWH project standards. They should have power to levy fine to such individuals or institutions.

It is said that if World War III happens, it will be due to water only.

Considering the current national and international water scenario, it is high time to implement stringent action plan for long-term water resource development. n Authored by_ Chitralekha Vaidya, Varshasookt Consultants

T

he ROCKWOOL Group of Companies is one of the world’s largest producers of stone wool insulation. Founded in 1937 and headquartered in Denmark, today the Group has around 10,000 employees and operates in over 40 countries across Europe, North America and Asia.

ROCKWOOL Asia has four stone wool factories located in India, Malaysia and Thailand and offices in Indonesia, Malaysia, Singapore, Thailand and Vietnam; serving the needs of customers all across South Asia to neighbouring countries of Australia, New Zealand, Japan and South Korea.

The ROCKWOOL brand is well recognised and established in Europe and worldwide as providing the highest quality insulation; offering consistent and lasting performance in fire, thermal and acoustics. Its solutions protect people from the cold, heat, risk of fire and unwanted noise while protecting the environment from the impact of buildings by reducing the energy consumed and lowering carbon emissions.

ROCKWOOL solutions for energy efficient buildings Heating and cooling are amongst the main energy consumers in buildings but most of this energy is wasted due to inadequate insulation.

By using well-proven energy efficiency techniques, 70 per cent to 90 per cent of a building’s energy need for heating or cooling can be cut. Better insulation is one of the

50

november 2014

most profitable ways to save energy wastage and CO2 emissions - it is a low hanging fruit.

Despite lack of regulations in building codes across Asia, architects and investors need to take up the challenge to design and build more sustainable ‘green’ buildings – which use less energy and emit less CO2. Sustainable buildings set a great example for governments to follow suit and improve building legislations in their regions.

Immediate action is crucial to avoid the consequences of extreme climate change as our life on earth depends on a delicate temperature interval of only a few degrees.

One of the key elements to reduce emissions by 60 per cent - 80 per cent before 2050 is to reduce the energy consumption in buildings.

According to CO2 abatement studies by McKinsey, insulation gives some of the highest financial gains for every tonne of CO2 it saves.

BKT: driving globe with off-highway tyres Balkrishna Industries (BKT) is one such company which is not only setting a trend but also creating its own niche

E

very company tries to identify an existing trend (socio-economic and market) and sell accordingly, but very few can breakthrough the obvious and dare to go beyond, creating not just success but also an unprecedented niche for themselves.

They become pioneers and go on to build, along with a strong company, a robust business culture that lasts for generations.

With more than 25 accomplished years of global leading presence in the off-highway tyres segment, Balkrishna Industries (BKT) is undoubtedly one such company.

Leading innovator In the early 1990s, when the other tyre companies in India were busy producing highway tyres for mass use, BKT foresaw a unique opportunity in international business and audaciously initiated production in the ‘off the highway’ segment. BKT’s products, owing to their state-of-the-art make and unmatched performance, found immediate recognition in global market, and there began an unending story of BKT’s triumph and innovation.

Today BKT enjoys principal presence around the world, encapsulating a staggering 130 countries and over. It is the preferred supplier to international OEMs in industrial, construction and agricultural tyre segments, and has grown since its inception in 1988 into a diversified industrial conglomerate exporting its expansive range of ‘off-highway solutions’ to the World.

Arvind Poddar, Chairman and Managing Director, BKT

State-of-the-art products Quality conscious users who adhere to stringent conformity standards in Europe and America prefer BKT as their supplier, thus implying that every BKT product is superior most in creation and delivers expected performance.

We have invested over $375 million in this plant.

This is a huge plant spread across 300 acres.

It will enhance our total capacity by 75 per cent

This is achieved by using the foremost quality of raw materials that are processed through the most advanced technology creating

a BKT product. “Our each product passes over 450 stages of tests. The result of this rigorous practice being that BKT products are known for their reliability and have the lowest claim ratio in the industry,” informs Rajiv Poddar, Joint Managing Director, BKT. The company has products from 5-inchrim diameter to 54-inch-rim diameter for vehicles, ranging from trailers, forklifts, etc. to technologically advanced machines like high horsepower tractors, combines, harvesters, GPS controlled vehicles, articulated dump trucks, high-speed cranes, sophisticated port vehicles and container handlers, and so forth.

All-steel radial OTR tyres BKT, continuing its legacy of taking gutsy decisions in business based on foresight, has ventured into the production of all steel radials since 2008. BKT is the first tyre company in India to produce the all-steel radial OTR tyres.

An all steel radial plant in Chopanki, Rajasthan, is now functioning on full throttle, producing top of the line radial tyres for OTR vehicles ranging from rigid dump trucks to snow manoeuvring vehicles.

These have already found strong appreciation in BKT’s chain of suppliers all over the world.

The tyres under this segment range from

Promotional Feature II Tyres a 20-inch diameter tipper truck size to a giant 51-inch rigid dump truck size, in both radial and bias make, thus covering one’s every requirement in industrial use and mining.

BKT also plans to unveil a more enviable and capable range of sizes for OTR solutions soon. To aid these ambitions, BKT has opened up another state-of-theart, advanced production plant in Bhuj, Gujarat, which will focus on producing top of the line OTR tyre with special focus on the radial segment.

Port tyres BKT has established itself as a one-stop shop for all OTR solutions — be it for mining or industrial applications.

And staying true to the image, BKT has initiated production of port tyres. And once again owing to excellence is product performance and make, these have found tremendous users not only across Asia but around the world through its supply chain spanning 130 countries and over.

There is a wide gamut of tyres available in this line, ranging from port reach stacker sizes to RTG sizes, BKT has them all.

BKT has been selling tyres to major companies like Kalmar Sweden, which is one of the world’s leading reach stacker machine manufacturers.

BKT has also recently launched an ultraadvanced range of tyres, especially for high speed cranes. The tyre 445/95R/25 enables heavy high-speed cranes to journey at an unprecedented speed of 80 km/hr.

Agricultural tyres BKT is a maker of the world’s most preferred tyres for agricultural use. The company offers a huge range of solutions for agricultural activities.

BKT’s range of tractor tyres is specially designed to carry higher loads on and off roads with minimal soil compaction in field. Their superior make ensures great road ability, traction and durability making them a fitting choice for today’s high horse power tractors and trailer applications.

A greenfield project The manufacturing plant in Bhuj, Gujarat, is the fourth manufacturing unit set up

by BKT in India. The project complex comprises of about 300 acres of land, just a few kilometres away from the Mundra port, offering logistical advantages in transport of raw materials. The site foresees a large warehouse and a specific area of about 15 acres dedicated exclusively to R&D. The testing facility at the plant is equipped with indoor and outdoor testing areas for the products, and there is a special testing track constructed to provide for test runs and on-field tests for the tyres.

Introducing the plant Arvind Poddar, Chairman and Managing Director, BKT says, “We have invested over $375 million in this plant. This is a huge plant spread across 300 acres and with the most modern machinery ever used in production in India.

The plant will enhance our total capacity by 75 per cent.” Once the Bhuj plant becomes fully operational, it will have the capacity to produce about 350 metric tonnes per day.

The real winning point is the social relevance of the plant. BKT has established a completely self-sustaining village around the 300 acres of plant site, where its employees and their families are living with complete facilities and requirements of modern living. Schools, hospitals, fire brigade stations, hotels and guest houses, you name it and the village has it.

For BKT, the Bhuj plant means an extraordinary 75 per cent increase in production which will add about 120,000 tonnes per year in addition to its 180,000 tonnes obtained from the other three plants. This facility also produces ultra large and giant OTR tyres up to 51-inch rim diameter.

Driving tomorrow The tyre markets in Asia have witnessed a strong surge in recent years, with India and China leading in growth and development.

Indian tyre companies are no longer just manufacturing tyres for commercial vehicles but the market has expanded encapsulating high-end consumers with heavy OE needs for industrial, construction and mining purposes.

Rajiv Poddar, Executive Director, BKT

Our each product passes over 450 stages of tests.

The result of this rigorous practice being that BKT products are known for their reliability and have the lowest claim ratio in the industry.

A company like BKT is a huge factor in this growth with its selling chains covering almost the entire world. However, as they say, with great success comes great responsibility.

Along with business interests, there has also been a strong escalation in application requirement demands by its consumers. Today BKT is manufacturing tyres for OEMs all over the world, offering solutions for heavy agro, industrial and mining solutions.

In terms of production, quality and performance norms have become more stringent – driven principally by emissions legislation – and with demands for fuel efficiency and continuing requirements for extended hardware durability, it has becomes increasingly important for big market players like BKT to not just provide for solutions for an OE machinery but also be involved with its development right from the beginning.

BKT is a vendor and collaborator with companies like Coal India, which is among the world’s largest OTR customers.

BKT is working intensively to be at tandem with the emerging needs of its OEM clients and has the shortest response period amongst its competitors when it comes to delivering a new product while keeping the costs low and efficiency high, adhering to the stringent most international standards. n
