CRITERIA 1

Criterion 4: Site imperviousness factor Intent: High imperviousness on site leads to rapid runoff of rainwater, reduces urban rainwater recharge and contributes to conditions of urban flooding. The intent of this criterion is to ensure implementation of site design measures which assist in reduction of overall site imperviousness factor.

Maximum Points: 1 Appraisals: • 4.1.1: Net Imperviousness factor of site meets the NBC 2005 norms & the site is designed such that postconstruction storm water discharge from the site is zero* – 1 point

Compliances: • 4.2.1: Submit calculations and drawing demonstrating compliance with Net Imperviousness Factor of NBC 2005 • 4.2.2: Submit calculations demonstrating that post construction, the site does not discharge any storm water outside the site • 4.2.3: Upload photographs, with description, of the measures implemented. * Analyse for the peak average daily rainfall of the year

Narrative: The idea is to reduce the imperviousness of the site, so that during the rainfall, the imperviousness of the site should not cause any urban flooding.

Few points taken from NBC 2005: • •

•

Pervious paving helps in holding rain water, reducing the rate of storm water flow, infiltrating storm water into the ground for reuse and also helps in filtering the rain water.

Besides helping in storm water management, pervious paving helps in reducing the heat Island effect. For sustainable site planning, perviousness in the paved areas of the site may be maximized.

However, the rain water harvesting potential of pervious paving is subject to local geomorphological formations and the use of the same should be assessed based on local conditions. For example, in coastal areas, where the water table may be high and the water absorptive capacity is low, pervious paving may not be as effective.

Below table is taken from NBC 2005 standards for imperviousness factor applicable to different types of area.

➢ Wheel washing systems can be installed on construction sites to enable the wheels of plant, trucks and other vehicles to be cleaned before leaving the site. This is used to control and eliminate mud, slurry and other pollutants being deposited on public roads. ➢ The system is typically located near to the site exit and instructions given to site operatives, delivery drivers and visitors that they are to use it before leaving. ➢ There are two main types of wheel washing system: • Roller: Each set of wheels is placed on the rollers and rotated as water sprays out from strategically-placed nozzles.

• Drive-through: The vehicle drives through and a sensor triggers the washing process. ➢ The sludge which is washed off may be directed into a recycling tank, with the sedimentation of the solids accelerated by the use of flocculants. The solids which settle at the bottom of the tank are removed by an automatic scraper or excavating plant. The aim is for clean water to be used for every wash.

CRITERION 5

• Washing of Equipment and Vehicles ➢ If washing vehicles on site, provide an effective means of minimizing the discharge of pollutants from equipment and vehicle washing, wheel wash water, and other types of washing.

• Storage of Products that have the Potential to be Hazardous or Toxic Waste Examples of hazardous or toxic waste that may be present at construction sites include, but are not limited to, paints, solvents, petroleum‐based products, wood preservatives, additives, curing compounds, acids. If storing any of the above products on the construction site, comply with the following: ➢ Provide the Resident Engineer with a plan as to where all hazardous chemicals and fuels storage tanks and containers will be located. This plan will include all safety and health precautions to be implemented to maximize safe handling and storage of chemicals and fuels. This plan and the location requested by the Contractor must be approved by the Resident Engineer before bringing chemicals and fuels onsite. ➢ 2. Store these products in water‐tight containers, and provide either cover (e.g., plastic sheeting or temporary roofs) to prevent these containers from coming into contact with rainwater or provide secondary containment (e.g., spill berms, decks, spill containment pallets) Disposal of Waste Products 1. Separate hazardous or toxic waste from construction and domestic waste. Mixing increases hazardous waste volume and consequent handling and disposal costs.

2. Store waste in sealed containers, which are constructed of suitable materials to prevent leakage and corrosion, and which are labelled in accordance with applicable Resource Conservation and Recovery Act (RCRA) requirements and all other applicable state, or local requirements. Label hazardous waste containers as such.

3. The Contractor can maintain waste materials and non‐emergency spills up to 2700 lbs. (approved container) no longer than 180 days from the accumulation start date. Obtain a licensed waste hauler to remove hazardous wastes (liquids, solids).

4. For construction and domestic waste: Provide waste containers (e.g., dumpster or trash receptacle) of sufficient size and number to contain construction and domestic wastes. In addition, clean up and dispose of waste in designated waste containers and clean up immediately if containers overflow.

5. Dispose of hardened concrete waste in ways that are consistent with Utah disposal laws for inert material 6. For sanitary waste: Position portable toilets so that they are secure and will not be tipped or knocked over.

Emergency Spill Notification Procedures: If the spill presents a potential for harm to personnel, public, or the environment, the Contractor is not able to immediately control and clean‐up the spill, and/or the spill exceeds the reportable quantity, the following actions shall be taken: ➢ Notify the Resident Engineer and the Region Safety Risk Manager to determine if the quantity or severity of the spill warrants outside assistance by emergency services (again, this is to ascertain the toxicity, size of spill, and if the spill could discharge to a surface water or a sewer/storm drain line).

GREEN BUILDING STUDIO

CRITERION 5

➢ If the spill is clearly an emergency hazardous spill condition, the Resident Engineer or the Region Safety Risk Manager will notify the Utah Department of Environmental Quality and the National Response Center. ➢ . Submit an incident report within 24 hours to the Resident Engineer. The Region Safety Risk Manager will review the report, and if necessary, hold a post incident meeting with the Contractor. ➢ It is recommended that the Contractor use a State Certified Hazardous Materials Lab when necessary to identify an unknown spill material. Identifying the type of spill material or liquid containment can save the Contractor from increase costs for disposal if the material to be removed is known. ➢ The Contractor is responsible for all required hazardous waste management which includes but is not limited to the transportation, storage, and disposal at a hazardous waste disposal facility.

•

➢ ➢ ➢

➢

Waste Disposal and Minor Spills: A minor spill is a condition that does not present potential harm to personnel and/or the environment, the Contractor has the ability to immediately control and clean‐up the spill, and the spill does not meet the hazardous spill definition. Actions to control non‐emergency spills involve the following activities from the Contractor: a. Immediately notify the Resident Engineer for verification that condition is a non‐ reportable minor spill. b. Begin spill clean‐up immediately and use trained personnel to respond to critical events involving spills. c. Use contingency clean up products and equipment to handle non‐emergency spills (absorbent materials, personal protection equipment, compatible empty container to store spilled material, fire extinguisher, etc.) d. Spilled liquids or solids are to be properly contained in a compatible container and stored on‐site until proper disposal action is taken as required by state and federal requirements.

Where a spill occurs or when hazardous wastes are generated the Contractor will fill out a hazardous waste label and establish an accumulation date. e. Submit a spill report to the Resident Engineer explaining the spill quantity and method of disposal including a Hazardous Waste Disposal Manifest if applicable.

CRITERION 7

Narrative Sustainability on construction sites and its impacts on the environment have become increasingly relevant.

Large quantities of materials, water and energy, among other resources of various types and origins, are consumed on construction sites during the production activities and by the temporary facilities. The main aim of this criteria is to ensure good and sustainable construction practices. ➢ 1.Adopt staging during construction on site These following phases can be applied: ➢ Initiation • When starting a building construction project, you will have to determine its feasibility by evaluating its pros and cons. In this phase, you will have to consider the objective of your project as it can be an opportunity or a problem for you as a builder. All the various options and solutions on how to build your project must be considered prior to taking the next steps.

➢ Planning • In this phase, the project has to be developed in detail to meet its objectives. The project manager’s team will define the work that needs to be done in order to start construction by identifying the resources and strategies to obtain supplies. An outline of the construction plan along with its timeframe and other activities has to be created in this phase for its execution. ➢ Execution, • This phase is also known as the implementation phase, since this phase of the project is practically put into performance mode. At each stage of implementation, it is necessary to communicate with the project manager’s team to control its expenses. The heads of all the teams executing the plan will submit their progress report to the project manager so that he can make the necessary adjustments. ➢ Monitoring, • In this phase, the performance and progress of the entire project is measured to ensure that the project is running as per the schedule. All the finishing works including woodwork, metalwork and painting, etc. are also monitored at this stage. ➢ The completion •

The completion phase is when the project manager has to finalize many things including: stopping the supplies, checking the final touches including planting and landscaping as well as cleaning the surroundings and do final inspection of the project before handing over the building to its owners.

CRITERION 7

➢ Adopt strategies to prevent/reduce movement of soil (not top soil) outside the site through adoption of various strategies (like soil erosion channels, sedimentation control etc.)

Sedimentation control

Soil erosion channels

These methods do not allow the movement of the outside soil to come inside the site. ➢ Using gunny bags for curing and using ponding for curing

Picture showing gunny bags used for construction

Picture showing gunny bags used for construction

Ponding method for curing

➢ GUNNY BAG METHOD ➢ This method is very useful for vertical surfaces of concrete like sides of column. Gunny bags (BORI IN HINDI) are made from jute and wrapped around the concrete and are kept continuously wet. Gunny bags absorb water and retain moisture for long time. Gunny bags can be used for many times and hence this method is very economical.

PONDING METHOD: ➢ A➢ construction waste management plan for segregation of construction waste, its safe s ➢ Ponding method is suitable for large and slabimplemented and for road pavements.

On top of the slab, small and on-site/off-site recycling is developed in the project. ponds are prepared from clayey soil, and water is stored up to a depth of 50mm for 28 days.

Water used in ponding should be of good or potable quality (water fit for drinking).

CRITERION 9

Narrative; Natural sources of energy, such as solar, wind, hydropower, tidal energy, ocean thermal, and hydrogen, are all renewable energy sources. The availability of these renewable sources and the minimum impact that it has on environment, is the driving force for increasing use of such renewable sources. Undoubtedly it brings financial benefits to the users after the payback period.

But along with the benefits, its operational and maintenance cost should be taken into account. Also such technologies should be user friendly and durable and flexible in longer run. The expertise required to install and maintain the system should be locally available. And the life cycle of such system should be designed along with the requirements to meet the future needs.

ACOUSTIC COMFORT: •

Acoustic comfort is often understood to be a situation where there is an acceptable level of noise.

However, the perception of sound is a much more complex issue, that depends not only on sound intensity and its temporal and spectral features, but also on the activity of a person, state of mind, and expectations among other factors.

•

Noise can be defined as “the sound occurring within the frequency range of the human hearing which disturbs silence or an intended sound perception and results in annoyance or endangers the health”.

Sound can be defined as a wave motion from a sound-producing object. It varies according to frequency and pressure.

STRATEGIES There are three basic strategies to impeove indoor air quality, they are; 1.source control 2.improved ventillation 3.air cleaners 1.SOURCE CONTROL It is the most affective way to improve indoor air quality by elminating sources of pollution And reduce their emission.

For example : sources like asbestos, can be sealed or enclosed, others like gas stoves can be Adjusted to decrease the amount of emissions.

2. IMPROVED VENTILLATION Ventillation can help control indoor tempretaures and also remove or dilute indoor airbone pollutants coming for from indoor sources, this reduces the level of contaminants and improve indoor air quality GREEN BUILDING STUDIO

CRITERION 12

•introduction of outdoor air is one of the important factor in proofing good air quality, air may enter the space through several ways I.through natural ventilation by doors and windows Ii.through mechanical means by hvac system Iii.through infilteration, aprocess by which outdoor air flows into the house through openings joints and cracks in the wall etc

3. AIR CLEANERS the most effective way to improve indooor air is to reduced or remove the pollutants using a portable air cleanser can help to improve indoor air quality .

MATERIAL SUITABLE FOR THIS From an indoor air quality perspective, the designer should generally seek to select materials that: •require the use of the least toxic, low-voc, water-based adhesives and coatings constituents; •emit little or no odor; •are easy to clean and maintain; and •are not susceptible to moisture damage that can foster mold growth.

Walls and ceiling materials • Acoustical wall and ceiling systems are widely used in schools for sound dampening.

• A variety of products are available including modular wall panels (textile and metal-covered), suspended ceiling tiles (t-bar ceilings), and surface mounted ceiling and wall panels.

• Ceiling tile (usually in a t-bar ceiling) is the most common ceiling finish in schools.

• Because of the large ceiling surface area, the likelihood of its being disturbed during modifications/renovations, and its contact with hvac systems, it is an important product to consider for air quality and materials efficiency.

Criterion 14: Use of low-flow fixtures and systems Intent: The intent of this criterion is to ensure reduction in the building water consumption through the use of low flow fixtures.

Maximum Points: 4 Non-applicability: All faucets, which are installed in spaces with water head heights less than 5 m / 17 feet, in a gravity fed systems (without pressure reduction) are exempt from calculations in this criterion.

Appraisals: • 14.1.1: Reduce water demand through selection of low-flow fixtures by 30% below the GRIHA base case – Mandatory • 14.1.2: Reduce water demand through selection of low-flow fixtures by 50% below the GRIHA base case – 2 points • 14.1.3: Reduce water demand through selection of low-flow fixtures by 70% below the GRIHA base case – 4 points

Compliances: • 14.2.1: Provide calculations demonstrating compliance with Appraisals 14.1.1 – 14.1.3 • 14.2.2: Submit specification sheets from manufacturers for each fixture indicating the flow rates (at design pressure of 45 psi for faucets) • 14.2.3: Submit purchase orders (reflecting full quantities) for the low-flow fixtures used in the project • 14.2.4: Upload photographs, with description, of the measures implemented.

Narrative: The fixtures play an important role in determining the water quantity been used, hence smart fixtures play a role here , they use high water pressure technique to control the amount of water been used, through these fixtures we can control the rate of flow , and if we compare these type of fixtures with the traditional one then the water, consumed through these fixtures is less.

For example, while normal taps have a usual consumption of 15 to 18 litres per minute, low-flow models can use as little as 2 litres per minute.These can be achieved in the following ways: • These can be done by • Install faucet flow aerators • Flow restrictors GREEN BUILDING STUDIO

Water Sense faucet aerators deliver a mixture of water and air to reduce flow rates.

They can cost less than a dollar each and can be screwed on to most existing sink faucets.

The appropriate flow rate for each faucet will depend on the intended use of the faucet These fixtures, similar to lowflow toilets, had to go through several design.

And since the units reduce the flow of hot water, they generate additional energy savings in water heating.

Food service establishments use roughly 51 billion gallons of water a year rinsing dishes with pre-rinse spray valves.

That is equivalent to one third of the water used in commercial kitchens.

Handwashing ~ 0.5 gallons per minute (GPM) Bathing and Dishwashing ~ 1.5 GPM

low-flow showerheads have reduced flow rates, from as high as 7.5 gpm to less that 2.5 gpm •

Install Automatic Faucets Automatic faucets are equipped with a battery orsolar powered motion sensor that opens the faucet valve in response to thepresence of a hand in close proximity.

Public bathrooms with high volume hand washing can benefit greatly frommotion sensing technologies as they cannot be left on for extended periods.

Low-Flow Tank Toilets Tank toilets operate using gravity from a raised tank to dispense water and flush out waste.

Some tank toilets are equipped with a dual-flush valve, which allows for a full flush as well as a reduced flush.

•

Simple aerators can be installed on many faucets to reduce the amount of water coming out.

•

•

Water Sense labeled pre-rinse spray valves (1.28 GPM) use 20 percent less water than federal standard, with no performance sacrifices.

When replacing faucets, always look for the Water Sense label, ensuring amaximum flow rate of 1.5 GPM.

Water Sense labeled low-flow tank toilets are independently certified to remove at least 350 grams of solid waste while using no more than 1.28 gallons per flush (GPF).

They can cut water use by up to 75%, which can provide a quick payback.

Flushometer toilets operate using water pressure from the supply system rather than gravity from the tank.

Flushometer toilets are also available in dual-flush models, which allow different flow rate options for solid and liquid waste.

Existing toilets can be fitted with a dual flush conversion device.

One drawback to flushometer toilets is they require considerable water pressure to function effectively. Before installing, determine if your water supply system is equipped to handle the project.

A single employee could flush a urinal 780 times in a year.

Water Sense labeled flushing urinals use no more than 0.5 GPF. Replacing just one older, inefficient urinal with a Water Sense certified urinal could result in savings of 4,600 gallons per year in a typical office building.

•

Older models use as much as 3-7 gallons of water per flush, while newer Water Sense certified models use between 1.28 and 1.6 GPF.

•

Ultra-efficient urinals have recently entered the marketplace that use a mere pint per flush, resulting in an 87 percent reduction in water use whencompared with a federal standard urinal (1.0 gpf ).

Waterless urinals use cartridges filled with a liquid sealant to create a fluid and odor barrier between the sanitary sewage and the bathroom environment, eliminating the need for flush water and reducing operating costs.

Most waterless urinals require the cartridges to be replaced four times per year.

Dual-flush models provide two options for flushing; • The liquid waste option - consumes 0.8-1.1 gpf, • The solid waste option -consumes 1.3-1.6 gpf • Pressure-assist toilets push water and waste down the drain with a pressurization system and use roughly 0.8-1 gpf.

• Use of Wash sink – Flush system.

• Use IAMPO certified water efficient products • .An average flush consumes 3.5 gallons (15.9liters) of water.

Water reuse—the use of treated wastewater, or “reclaimed” water, for beneficial purposes such as drinking, irrigation, or industrial uses—is one option that has helped some communities significantly expand their water supplies.

We can use the Root zone treatment plant As the root zone waste water treatment system makes use of biological and physical-treatment processes to remove pollutants from wastewater. Due to its natural process, there is no need to add any input such as chemicals, mechanical pumps or external energy. This reduces both the maintenance and energy costs.

The water received on the rooftops are collected using split pipes and downpipes.

The downpipe is provided with a valve to regulate the rain water collected.

The rainwater collected in the first couple rains is flushed out by regulating the valve Rainwater collected is allowed to flow into a filter unit.

This water is then filtered through filter media.

The filter media consists of sand, charcoal to filter the rainwater.

This filtered water is recharged into open well/ bore well

Sand, through which wastewater flows relatively slow, is typically used for single-pass filters. Gravel is typically used for recirculating filters which can accept larger amounts of wastewater than single-pass sand filters Charcoal filter can be made in-situ or in a drum. Pebbles, gravel, sand and charcoal as shown in the figure should fill the drum or chamber. Each layer should be separated by wire mesh.

Advantages of fly ash bricks compared to clay bricks 1. They are light in weight and hence are very suitable for multi-floored buildings 2. Fly ash bricks absorb less heat and considering the Indian climate, it makes it better when compared to clay bricks.

3. From the cost front, it requires less mortar during construction.

4. The compressive strength is very high and they are less porous. They absorb less water and saves cost there, as well.

5. It is environmentally friendly and hence allows your business to take a step towards sustainable development. Q-Green machines are green machines too, that promote environmental protection and conservation. Production of fly ash bricks requires no fossil fuel and hence does not lead to the emission of greenhouse gases.

6. Production of clay bricks damages the top-soil and this is prevented in the manufacturing process of fly ash bricks. There is no pollution or environmental damage, as a result of which it has been put into the white category of products.

7. Fly ash bricks are stronger, more uniform and denser as compared to clay bricks. While their mortar consumption is low, their wastage is only about 1% as against that of clay bricks which are about 10%.

Narrative: The aim of this criteria is to reduce the total embodied energy of the building through the use of light weight materials, like AAC blocks etc.

What is embodied energy of a building?

Embodied Energy as the energy required to construct and maintain the campus, for example, in reinforced concrete construction, the energy required to quarry the coarse and fine aggregate, transport them to site, lay them, plaster them and (if necessary) paint and re-plaster over the life of the respective element.

It depends upon the thermal conductivity of the material

ANALYSIS OF DIFFERENT MASONRY MATERIALS

It is observed from the above analysis that the SMB block has the least embodied energy and has been ranked one and the AAC block has been ranked 2, AAC block have the least thermal conductivity, so the SMB material is the most energy efficient but here if we compare it to the lifespan then AAC blocks would be the most energy efficient material with light weight .

AAC block is the least weight material compared to all the 6.

The above are the variety of AAC blocks , Which can be used for construction.

AAC walls can be used for the construction , which will reduce the overall weight and it has the lowest embodied energy and is the most efficient material.

Calculation: Embodied energy is measured as the quantity of non-renewable energy per unit of building material, component or system. It is expressed in megajoules (MJ) or gigajoules (GJ) per unit weight (kg or tonne) or area (m2) but the process of calculating embodied energy is complex and involves numerous sources of data.

Narrative: The most important reason for waste collection is the protection of the environment and the health of the population. Rubbish and waste can cause air and water pollution. ... Waste collection companies also sort the garbage into recyclable columns, as recycling the products that leave our homes is of utmost importance This can be achieved in the following ways: •

To REDUCE the amount of waste we produce.

•

To REUSE resources or pass them to others to do so.

•

To RECYCLE by segregating materials which cannot be reused.

•

To RECOVER energy from materials which can’t be recycled.

•

To LANDFILL resources only as a last resort.

Waste management hierarchy The management of waste described in this procedure should follow the waste manageme nt hierarchy options listed below in order of priority: • Avoid • Reduce • Reuse • Recycle • Recover • Landfill Avoid Possible to look for opportunities to avoid unnecessary consumption and generating controlled wastes. Waste avoidance can be achieved through behaviors such as: • Avoiding disposable goods and single use materials; • Avoiding the use of hazardous substances in preference for non‐hazardous substances; • Avoid disturbing contaminated soils where practicable; and • Education of workforce on waste avoidance.

GREEN BUILDING STUDIO

61

CRITERION 22

For example, avoid putting contaminated materials into recycling bins which could result in the entire contents of the bin becoming contaminated and no longer suitable for recycling.

Reduce Possible opportunities to reduce waste should be identified prior to the procurement of equipment and materials. Waste reduction can be achieved through behaviors such as: • Identification and segregation of re‐usable materials; • Procure products with longer life cycles; • Use products with recyclable or reusable packaging; • Print double sided paper; and • Education of workforce on waste reduction.

For example, the purchase of supplies in bulk to minimize packaging waste.

Reuse Possible, reuse materials in preference to purchasing new materials. This can be achieved by behaviors such as: • Reuse excess fill from other projects for your project avoiding purchasing new fill and saving on landfill charges for the other project; • Use rechargeable batteries; • Purchase recycled office materials; and • Education of workforce on waste stream segregation.

For example, collect and reuse pallets, form work and concrete boxing Recycle Possible, waste material suitable for recycling will be collected and segregated. This can be achieved by: • Identification and segregation of recyclable materials; • Placement of designated recycling bins in appropriate locations; and • Education of workforce on recycling.

GREEN BUILDING STUDIO

CRITERION 22

For example, collection of used cardboard packaging, plastics, cans and bottles for recycling.

Recover Where further recycling is not feasible, it may be possible to recover the energy from the material and feed that back into the economy where this is acceptable to the community.

For example, waste insulating oil used in the process of making cement

Landfill Finally, the waste hierarchy recognises that some types of waste, such as hazardous chemicals or asbest os, cannot be safely recycled and direct treatment or disposal is the most appropriate management option.

Compliances: • 26.2.1: Submit drawings demarcating the location of various toilets and/or resting rooms for service staff • 26.2.2: Upload photographs, with description, of the measures implemente Narrative; Everyone, regardless of whether you are the Government, an employer, a service buyer or a concerned citizen, must realize that architects have a part to play in uplifting the lives of our low-wage workers.

A cause that all of us could be a part of is ensuring that our companies provide proper rest areas for outsourced workers such as cleaners, security officers and landscape maintenance employees working in our building premises. These workers put in effort and hard work performing their duties, and the fruits of their labour result in a better environment – one which is clean, safe and secure – for everyone at the site. Surely, these workers deserve the dignity of having proper rest areas so that they can carry on doing their work more productively.

Most companies provide good, proper rest areas for their permanent employees. Unfortunately, the provision of rest areas by service buyers or building owners for their cleaners, security officers and landscape maintenance workers is uncommon. Many of these outsourced service workers have no choice but to accept whatever nook or corner, albeit undesirable, as their rest areas.
