ABSTRACT This research is focused on the study of Information Technology campuses and the architecture that defines the social structure of the project. This study will help in getting an idea of the evolution of workspaces and what factors are important while defining such a space. Also, the growing trends have been studied to notice the changes in the facilitating spaces that have taken place in this field.

The methods involved in depth study of similar Information Technology parks, and Spaces of Innovation which have been changing according to the need of time. This shift in practice & work culture has relation to new generation of people demanding change in their work environments. Companies have found a way to attract & retain talent by making their workspaces more elegant, warm & welcoming. This change has been a move away from the traditional closed office spaces which focused solely on sizing & storage needs. Research on such aspects will help determine the benefits of this new culture, along with its cons.

Further, local bylaws help understand the context of the surrounding projects. The findings of the study & the standards for building have been used to create a design programme for the proposed Information Technology Campus.

The focus of this research stands on why innovation design matters & finding the right key outcomes to follow as a guide to realize this research.

Chapter – 1: Introduction 1.1 Background Study In the last decade, technology has changed how we live our lives, interact with people, implement our work, etc. At the heart of all of this change is Information Technology which has driven this exponential growth. This integration with people & technology has given rise to new opportunity in the urban sector. There has been a sharp rise in the number of startups, and established companies diversifying their businesses in this InfoTech arena. This need explains the growing number of businesses adopting IT enabled services to expand their business.

We have seen a growing number of InfoTech campuses, data centers in the recent years to serve this digital age. But we haven’t witnessed any change or innovation in the architecture of these complexes. Due to this reason we are watching a replication of concepts in all of these implementations. These campuses speak a language which doesn’t correspond to its surrounding and is unwelcoming to a large user group.

What remains to be seen is how much can we change without affecting the functionality, security concerns, and convenience by blending its architecture into urban fabric.

1.2 Project Justification An Information Technology campus with centres of innovation for small businesses or startups acts as a great boost for the economy. Incubators and Accelerators have been changing the dynamics of these spaces as these spaces are a playground for ideas to come to reality. The adoption of this idea has been very less compared to the growing need for technology. An inclusive Information Technology campus would be an ideal for business and such projects to become a commonplace.

1.3 Aim & Objective Aim: To realize a socially inclusive Information Technology campus by complementing the Urban context of cities.

Objective: 1. To provide a sustainable habitat for the new Information Technology campus.

2. To create open environment that is contextually responsive.

3. To provide efficient working spaces that would encourage communication, interaction and collaboration.

4. To utilize Appropriate Technology in the campus, while keeping urban context, future growth in mind.

1.4 Scope, Limitation & Methodology Scope: 

The scope of this project outreaches different programs that might involve diverse professionals to work together.



As a technology park, workshops, training programs that include university students to work with professionals can be encouraged which benefits both the parties.



Public inclusivity in the campus is encouraged through symbiotic relation with the owners & the users.

Limitations 

Client requirement may not necessarily match the user requirement which is what the spaces are about.



This research does not address the economical aspects involved with the innovation spaces like Accelerators & Incubators.

Methodology 1. To study the existing architecture of InfoTech campuses in India.

2. To analyze the context of these campuses and the services technology in use.

3. To find a suitable site and environment for this new campus.

4. To create a design programme with comparative analysis of such projects.

5. To analyze the Development Control Regulations for right planning mechanism & avoid pitfalls.

Chapter – 2: Research Study 2.1 India & its IT Scenario Indian IT-BPM (Information Technology – Business Processing Management) is exponentially growing year over year. The Industry continues to experience double digit growth. Rapid transformation in Technology is changing client engagement, resulting in rapid business transfiguration, faster delivery services & increased innovation capabilities across industry practices.

Global technology spending is increasing, while the reducing time cycles for upgradation of technological infrastructure is optimistic for Indian IT-BPM industry. This in turn reflects to change driven by the improving global economic climate.

In the coming years, India is poised to be one of the most digitized countries in the world. The Government has also boosted the ease of doing business with reform-oriented approach and this has led to streamlined business environment. It has also committed to adopt technology for driving governance & embracing solutions to achieve its developmental objectives.

The recent changes from visa regulations to automation in service sector, and adoption of disruptive technologies in operations has had a significant relevance on the future of Indian IT sector.

Due to the current development trends, the Indian IT industry needs to evolve to compete with the technological shifts happening in the industry. As a response to this shift, creativity, intellectual property, & delivery of the finished product will be critical for companies. This requires focus on innovation as a foremost priority for leading companies. Thus it puts the latter in a position, where we will likely see significant breakthrough in ideas and applications for the new economy.

Workflow for Enterprise Resource & Planning software businesses in India

Startups & Economy India has third largest number of start-ups in the world, just behind US & UK on the top two positions. The number of start-ups grew from 4200 in 2015 to 4750 in 2017, and it ranks higher than technologically driven economies like Japan, China, Israel, & Germany. This movement has been fueled with Government efforts like ‘Start-up India, ‘Make in India’ and ‘Digital India’ platforms which subsidize or make easier policies for new companies.

The current growth in Economy added to the growing Internet penetration of the citizens has boosted growth for digital sectors including e-commerce, online businesses, networking apps, media companies, etc. This in turn drives Foreign investments to Indian markets which keeps the competition healthy, sustainable, & innovative.

2.2 Innovation Spaces Innovation spaces could simply be defined as spaces

(Grech and Walters 2008)

where innovation takes place. Be it laboratories, studios, workstations or any place designed to invigorate thinking. Innovation spaces are vital for groups invested in technology as they are driving factors to bring disruptive technologies to the market. The key components of these spaces are people and people are the greatest asset to any company or group, for without people nothing has value.

The growing trend of open and collaborative spaces to

The language bridge

become workspaces is largely driven by people. The conventional thought of such workplaces to become a common place is a rising phenomenon. This has catalyzed a new form of structure that has helped foster ‘cross-disciplinary’ approach to urban growth & development. (Wagner and Watch April 10, 2017). [i] Traditionally if we see workspaces would be places where people work in traditional hierarchical offices where the focus would be on individual work. Though people who are more likely to driven research in groups are likely to bring innovation, disruption, and also have more chances to have cited in featured works. This only enforces the ideology that two heads are better than one.

In terms of workplaces, open collaborative spaces are more likely to bring cross-disciplinary talents together to work on solutions which bring the best of both disciplines. This with the growing trend of field of data analysts, working in tandem with multiple disciplines to incorporate Artificial Intelligence to identify & solve problems shows the potential of people across disciplines working & achieving great potentials.

Technology largely supplements existing disciplines with the wheels to drive progress in the speed needed to sustain in today’s competitive environment. The convergence of people from different disciplines to work together has the same idea, to bring perspective to something that is traditionally being viewed only in a single manner. This practice brings a lot the table

[i] April 2017, Innovation Spaces: The new design of work – Julie Wagner & Dan Watch, Brookings Institution

where people tread with a depth to the existing problems which cannot be possible without the right feedback to the subject matter.

Time & study has proven how people can make great changes only if they choose to come together & strive to resolve challenges and have a better outcome. It can help address multiple social stigmas which were strengthened with traditional practices & behavior.

Innovation spaces bring inclusivity to the workspaces, helps build social networks, strengthens workflow, and brings capital accumulation. This shows us that the aim of Innovation spaces is to help people flourish. (Wagner and Watch April 10, 2017) [ii]

2.3 Research Component: Building envelopes in Office buildings to reduce energy impact.

This research focuses on the different exoskeleton & façade systems that have been implemented to reduce overall energy impact of a building. As energy is consumed in multiple ways, the major focus of this research is based on those examples that have been innovative to make a structure consume less energy. Minimal energy consumption may be achieved with reduced dependence on HVAC systems, efficient programs with an economical outlook, use of Solar, Wind and renewable energy, and climate responsive planning, etc. The focus majorly remains on saving more of energy with the help of structural systems, and not binding to one single technique or system.

SC Johnson Wax research complex Concept: Office as a forest open to sky Frank Lloyd Wright designed the SC Johnson Wax Research/Johnson Wax headquarters in Racine, Wisconsin with Natural Architecture as a concept. It is formally known as the Johnson Wax Administration building – it was completed from 1936 to 1939. It facilitated as the main office for SC Johnson & Son, the American manufacturer of household cleaning supplies.

Wright designed the building in his organic architecture style with reference to natural forms. This has been characterised in the main hall office space, which is often described as forestlike.

It is known as the Great Room, the double-height space which features treelike dendriform columns that sprout from Pyrex glass created a new kind of skylight that changed the environment of the workspace

nine-inch diameter and widen to create lily-pad shaped concrete tops.

The best feature of the space are the

Skylights which are made of pyrex tubing set between the pads to offer a diffused lighting

effect above the canopy. The pyrex extends downwards to the top of the walls to create clerestory windows.

The reason why Wright chose skylights (who also illuminated Larkin Administration Building from above) instead of façade was because he wanted to block views of the surroundings.

With the provision of new model office spaces with open-plan (first of its kind) layout, Wright’s design was built using advanced construction techniques. Also a mezzanine level surrounding the office space was designated for the administrators with views to the floor below.

Pyrex Glass tubing was also used to create wall dividers inside the building. He personally designed all the furnishings, with red tones that took cues from natural earthy hues. Other features include curved “Cherokee” red brickwork gives the building a new definition, normally different from his straight-edged shapes inspired from Prairie style. (Gibson 2017)[iii] New York Times Building Concept: Filtering the transmission of heat & light with blocking screen Renzo Piano designed the New York Times building for the Newspaper giant in Midtown Manhattan, NYC. It consists of Class A Office spaces & ground floor retail space. It has 52 stories and was built from 2004 to 2007. The building is 746ft. tall, with the curtain wall ending at 819ft. and the mast topping out at 1046ft. It is located at 620 Eighth Avenue between 40th & 41st streets in Times Square.

[iii] June 2017, Eleanor Gibson, Article: Frank Lloyd Wright designed the Johnson Wax offices as a forest open to the sky

Before the employees started occupying the building in mid-2007, the Times’ facility team had approached building scientists at Berkeley Lab’s Environmental Energy Technologies Division (EETD), looking for solutions. They were looking for reliable and affordable technologies, to regulate daylight in the new building which were not yet available in the marketplace. The team had set high goals set for comfort & productivity of the employees who would be working in the new building’s interior spaces for day and night. But they were having trouble finding integrated systems that could manage daylight, glare, and cooling loads for architect Renzo Piano’s forward-thinking design. (Chen 2007) [iv] The design of the building includes an all-glass curtain wall layered with an external open screen, composed of horizontal ceramic rods suspended at 1.5 feet from the façade. The building utilizes water-white windows, exposed steel columns, and accents of red and gold making it a fitting home for 21st century media company. The themes incorporated into the architecture were volume, views, light, and respect for context and relationship to the street to provide a design that is open and inviting. This in substance presents occupants with a sense of the city around them.

Renzo Piano’s intention was that to have sunlight streaming into Ceramic Rods helped reduced the heat gain & permitted use of clear glass

the building resulting in more natural lighting, and the transparent façade would allow

passersby to see inside; New Yorkers could see inside their hometown newspaper at work.

The fixed array of ceramic rods was intended to assist in regulating solar gain. Renzo Piano felt that exposure was very important. The exposed structural members also serve as essential elements of the design by adding visual interest to the façade and a firm complement to the lightness of the ceramic rods.

[iv] October 2007, Allen Chen, Article: Back to The Times - Revisiting The New York Times Headquarters Building Upon Its Completion

Another key design feature is the idea of the building to appear lighter and more transparent as the skyscraper moves upward toward the sky. This gives the effect of the building disappearing into the sky. Renzo Piano accomplishes this by reducing structural member size as the building moves upward. This is also fulfilled by increasing the spacing of the ceramic tubes that act as the sun screen. The last effect is taking the ceramic tubes approximately 75ft. above the 52nd and final floor. This enhances the effect of the building disappearing into the sky as well as hiding some mechanical equipment located on the roof.

Meanwhile at the Berkeley Lab, scientists used the Radiance daylight simulation program to perform simulations of the interior spaces, created realistic renderings of inside light levels under different Workers removing the ceramic rods at NYT building after a third climber used it as ladder-like rungs (Photo credits: David W. Dunlap/New York Times)

day and night conditions. They provided the resulting data to manufacturers to help them finetune their control systems design.

Consultants to The Times used EnergyPlus building simulation software to evaluate the demand-response potential of individual systems, seeking to join the heating, ventilation, and air-conditioning (HVAC). (Chen 2007) [v] The Times building’s final system consists of mechanical shades controlled by electrical motors, six shades per motor. A network of photo-sensors continuously measures the lighting levels, and a computer decides when to raise the shades to let in more light or lower them to reduce glare from too much sunlight.

The lighting system also incorporates innovations which are unusual for a large commercial structure. The fluorescent office lighting is dimmable, when Dimmable fluorescent systems are expensive. The Times was able to negotiate pricing appropriate to their budget – and in the process drove down the prices of these systems in the larger marketplace. Each lighting fixture can be controlled separately by computer through the ‘direct addressable lighting interface’ (DALI) protocol, the lighting control industry standard. (Chen 2007) [vi] [v], [vi] October 2007, Allen Chen, Article: Back to The Times - Revisiting The New York Times Headquarters Building Upon Its Completion

Interior Architect Gensler worked with collaboration with The New York Times Company, Renzo Piano Building Workshop and FXFOWLE to create a functional, aesthetic, sustainable and progressive interior environment that would be well integrated into the building design.

By being included in design meetings with the architects, Gensler was able to optimize the interiors as well as the core and shell architecture. One main goal was having an open and flexible workspace. By consulting with the architects Gensler was able to create a unique continuity of interior-exterior design, flowing seamlessly from the public spaces to the office floors.

There is a four storey pedestal that contains retail space along with a cultural center and performance space. There is also an open air, 4 storey tall birch birch garden containing seven 50ft. tall paper birch trees.

Conclusion: Well planned Building envelope address numerous factors from building an identity for the structure to speaking the views of the habitat. This shows that facades are not just a protective shield for the building but also a matter of statement, & symbol of architecture.

Innovative facades have always invigorated thought, & curiosity of the viewer. The utter simplicity behind the idea along with the workmanship are key factors for a faรงade that is innovative and right for the environment. Also, the amount of detail it exhibits has a quite astonishing factor which makes facades very interesting in the first place.

Along with aesthetics, facades help reduce heat gain, provide diffused lighting, & can play a variety of functions based on the design of the faรงade. This proves that Building envelopes play a lot bigger role than just enclosing the habitat and give a lot of room for improvement.

Fire Command Center (According to NBC 2016) [3.4.12] Fire command centre shall be on the entrance floor of the building having direct access. The control room shall have the main fire alarm panel with communication system (suitable public address system) to aid floors and facilities for receiving the message from different floors.

All controls and monitoring of fire alarm systems, pressurization systems, smoke management systems shall happen from this room. Monitoring of integrated building management systems, CCTVs or any other critical parameters in building may also be from the same room.

Pressurization System Pressurization systems are employed in stairwells, elevator shafts, refuge spaces & other egress routes to control smoke movement across a barrier. By implementing in an area designed for safe exit, they maintain a high pressure against the area exposed to fire. This prevents smoke infiltration through cracks, joints, slits, etc in the egress area thus protecting them for a safe discharge of people. Pressurization Systems work in contrast with Exhaust & dilution systems.

VFD (Variable Frequency Drive) is a modern development in Pressurization Systems which regulates the pressure (by altering the fan speed i.e. RPM) in the stairwell my measuring pressure differences between occupied areas & pressurized stairwell.

Current industry practices estimate power requirements at an average of 50 to 150 WPSF, but as the servers and storage systems become ever more powerful and compact, they place a greater strain on the facility to deliver more power, reject more heat and maintain adequate backup power reserves (both battery backup and onsite power generation). In addition, more power requirements for the HVAC system will become necessary. A standard practice is to add 70% to the total IT equipment power needs.

Direct Expansion Refrigeration System (DX) vs Chilled Water unit system Direct expansion (DX) systems comprise individual compressors within each of the air distribution units in the data center. The coefficient of performance (CoP) for these systems ranges between 2.5 and 4, but are generally less expensive for initial installation costs. Chilled-water systems offer very high energy efficiency and can operate with a CoP greater than 7. These also allow for excellent part load efficiencies. However, they are a far more expensive option compared to DX. Ventilation for Pressurization Ventilation (outside air supply) is required within the data center space for pressurization and to maintain acceptable indoor air conditions for the occupants. In this context the outdoor air requirements should be in accordance with ASHRAE Standard 62, which calls for a minimum 15 CFM per person.

However, in almost all instances where the introduction of outdoor air is intended for pressurization purposes, it can be expected that the flow rates required will be in excess of that required for maintaining indoor air quality.

The data center shall be positively pressurized to reduce air infiltration from the surrounding areas. The air tightness of data center rooms has to be sound, and the degree of over-pressurization has to be sufficient to neutralize the influence of wind forces, temperature differences and surrounding process spaces which may be operating under negative pressure. A positive pressure level of 0.02 inches of water Âą .01 is recommended as the basis for design.

All the designated openings such as doorways or the undesignated openings such as tiny air gaps around doorframes or other duct/piping penetration cracks will cause air leakage. This leakage is compensated by the HVAC system by distributing the controlled volumes of supply, return and exhaust airflow to the room.

Consider the figure, where Room 1 (data center) is connected to Room 2.

To achieve and maintain positive pressurization in Room 1, P1 > P2; i.e. the supply air (SA1) must be greater than the return air (RA1) plus the exhaust air (EA1).

SA1 > (RA1+EA1), and SA2 < (RA2+EA2) SA1 = (RA1+EA1) + Q SA2 + Q = (RA2+EA2) Q is the leakage (transfer) air from Room 1 to Room 2, if both rooms are tightly sealed, except for the opening between rooms.

Data Center Cooling The heat produced or removed from data center equipment and auxiliaries is usually expressed as the number of Btu generated in an hour (Btu/h). Watts (W) is also a term used to express heat. One watt is equal to 3.412 Btu/hr. Air conditioning capacity is also measured in Btu/h or watts. Large air conditioning systems are rated in tons. One ton of air conditioning is a unit of cooling equal to 12,000 Btu/h or 3.52 kW thermal energy.

Calculation Method: A typical data center also has a cooling density (heat load) of 50 W to 150 W per sq. ft. A small data center sized for 5,000 sq. ft. is equal to [50W x 5,000 sq. ft. x 3.412 / 12,000 = 71 tons of cooling] at the low end and [150W x 5,000 sq. ft. x 3.412 / 12,000 = 213 tons of cooling] at the high end.

The capacity of the cooling equipment is normally specified in BTU/h and is often expressed in tons of refrigeration, where one ton of refrigeration corresponds to a heat extraction rate of 12,000 BTU/h. The ton rating is very subjective because it is based on total cooling which is comprised of "sensible cooling" and "latent cooling." temperature, but no change in the moisture content. environment.

The cooling capacity stated for a comfort unit is usually its total cooling capacity (i.e. sensible + latent). But since the electronic equipment generates only the dry heat (no moisture), the sensible cooling capacity becomes the most useful value for data centers. The common way to express this is by the sensible heat ratio which is: Sensible Heat Ratio = (Sensible Cooling/Total Cooling) For comfort air conditioning, the SHR is 0.60 to 0.70; that is the coil/air flow is designed to remove 30% to 40% latent heat load (moisture) and 60% to 70% sensible heat load. The cooling equipment for the data center is designed for 0.85 to 0.95 SHR; that is 85% to 95% sensible heat load and 5% to 15% latent load. These units will remove the high sensible heat load produced by the electronic equipment in a data center.

The cooling equipment used for data centers is commonly known as “Precision air conditioning units” or “Computer room air conditioners (CRAC’s)”. By design these virtually deliver 100% sensible cooling and maintain the temperature within closed tolerance of ±1°F and ±3 percent relative humidity of their design set point. Typical comfort systems simply cannot provide this level of control, and the very best that can be expected is ± 3°F. From an airflow standpoint, these Sameer Jadhav | 5th Yr.

provide a very large volume of air. If we compare this equipment to a comfort air conditioning system which moves air at a rate of about 400 cubic feet per minute (CFM) per cooling ton, the CRAC units are designed to move air at about 500 and 600 cubic feet per minute (CFM) per cooling ton. This is nearly twice the amount of air. The much larger air volume contributes to good air distribution and provides a better level of filtration.

Water Cooled Chiller (part of Central Chilled Water System) With water cooled chillers, the refrigerant is cooled with a shell and tube condenser that is part of the chiller package. The condenser water heat is then rejected to the cooling tower located outdoors.

A chilled water system utilizes a secondary cooling medium, i.e. the refrigeration cycle first produces chilled water, which in turn is used to cool air. Water lends itself as a superior cooling medium primarily on the account of its easy controllability and it doesnâ&#x20AC;&#x2122;t have any distance limitations.
