5. AIR ENVIRONMENT
5.1. Will the project increase atmospheric concentration of gases & result in heat islands? (Give details of background air quality levels with predicted values based on dispersion models taking into account the increased traffic generation as a result of the proposed constructions)
Given the activity, size of the project and the fact that Dual Fuel Generator sets are the only source of air emissions which are operated only during power cuts and also that the fuel used is Ultra Low Sulphur Diesel, dispersion models are not generated. Decision is taken based on experience and judgmental logic.
The impacts on ambient air quality due to emissions from the operation of Generator sets (only during power cuts by BESCOM) in the project will be very minimal as the Generator sets will be operated on Dual Fuel Mode and with low sulphur HSD (<0.005%) fuel. The movement of vehicles from this project will be under the surveillance of the security group that will be deployed to manage internal traffic. During construction phase, monthly ambient air quality monitoring for major parameters such as Particulate Matter (2.5 & 10 micron), Oxides of Sulphur & Nitrogen and Carbon Monoxide at two major locations within the project site will be conducted. Employees will be encouraged to keep their vehicles with valid emission certificates to ensure that the air quality levels are within permissible limits, due to the addition of traffic generated by their vehicles.
5.2. What are the impacts on generation of dust, smoke, odorous fumes or other hazardous gases? Give details in relation to all the meteorological parameters.
The main source of emission during the construction period are the movement of machinery equipments at site and dust emitted during leveling, earthworks, foundation works and other construction related activities. The dust emitted during the above mentioned activities depends upon the type of soil being excavated and the ambient humidity levels. The impact is likely to be for short duration and confined locally to the construction site itself. The composition of dust in this kind of operation is however mostly coarse particles, inorganic and non-toxic in nature. These are not expected to travel long distance before settling. Excavation during windy days shall be avoided.
Exhaust emission from vehicles and equipment deployed during the construction phase also result in a marginal increase in the levels of SO2, NOx, PM and un-burnt hydrocarbons. Construction activities may
Environment Clearance 18 | P a g e
Terms of Reference (TOR) Mysore Projects Private Limited cause changes in the PM levels locally, the impact will however be reversible, marginal and temporary in nature.
The impact of such activities would be temporary and restricted to the construction phase. The impacts will be confined within the project boundary and is expected to be negligible outside the project boundaries. Proper upkeep and maintenance of vehicles, sprinkling of water on roads at construction site, providing sufficient vegetation etc are some of the proposed measures that would greatly reduce the impact on the air quality during the construction phase of the project.
The impacts on ambient air quality due to vehicular emissions will be very less and will only be during the peak hours. The Entry and Exits will be manned by trained and experienced traffic wardens. Stopping or parking near the Entrance and Exit portals will be prohibited. The long driveway leading to the Parking bays and areas will ensure that vehicles do not get piled up. Also, visitor’s cars with valid emission certificate will be allowed within the building, as required.
5.3. Will the proposal create shortage of parking space for vehicles? Furnish details of the present level of transport infrastructure and measures proposed for improvement including the traffic management at the entry & exit to the project site.
It is proposed to provide ample car parking space within the project site. 10,000 car park spaces are proposed to be provided in the three basements & surface.
The Entry and Exits will be manned by trained and experienced traffic wardens. Stopping or parking near the Entrance and Exit portals will be prohibited. The driveway leading to the Parking bays and areas will ensure that vehicles do not get piled up. It is proposed to provide bell mouth entry and exit for smooth flow of vehicles into or out of the project.
5.4. Provide details of the movement patterns with internal roads, bicycle tracks, pedestrian pathways, footpaths etc., with areas under each category.

There will be two Entry and Exit points (both located at opposite ends), each 6.0 m wide to enter & exit the property. The width of the internal road is 8m (as per Fire regulations) and uni-directional. The traffic circulates around the property and becomes bi-directional at the
Environment Clearance 19 | P a g e
Terms of Reference (TOR) Mysore Projects Private Limited entry/exit point. The entry and exit to the project will be scientifically designed to ensure that there is no bottle neck situation onto the main road.
The internal road with the movement pattern is shown in the site plan. Speed breakers will be provided on the internal driveway as well as in the basement parking at regular intervals, to restrict the speed of vehicles within the development. Trained security will be deployed to ensure smooth flow of traffic into and out of the mixed use development.
5.5. Will there be significant increase in traffic noise & vibrations? Give details of the sources and the measures proposed for mitigation of the above.
There will be slight increase in traffic and noise during the peak hours, but that will be maintained by providing wide roads and proper signage internally and security group will be hired to maintain the flow of traffic outside the project site. “No Horn” sign will be installed at regular intervals along the drive way to minimize noise levels within the development.

9.1. Give details of the power requirements, source of supply, backup source etc. What is the energy consumption assumed per square foot of built-up area? How have you tried to minimize energy consumption?
The project proposes to have 45MVA sanctioned power from BESCOM. Acoustically enclosed Generator sets will be provided as back up during power break down. Back-up power requirement will be designed for bare minimum. 50% back-up will be provided for the residential buildings and 100% for commercial buildings.
Following are the methods proposed for the project to minimize energy consumption 50% of the external lighting is proposed on solar. These are set of lighting which are placed at critical junctions and which would be lit round the night. Alternatively, the other 50% lighting is on timer circuits to achieve the maximum savings. All the lighting are proposed to work on high energy efficient lamps (CFL)/ Light Emitting Di- ode (LED) as specified in Bureau of Energy Efficiency(BEE), which again results in saving in general consumption. The LPD is working less than 1W/m2 . All internal common area lighting system is proposed to have either high efficiency lamps (T5/T8)/ CFL/LED. These give us a LPD less than 10W/m2 but still achieves the required 200 LUX for ambient lighting. The top two floors of the residential buildings shall be provided with provisions for solar geysers which results in energy savings.
9.2. What type of, and capacity of, power back-up do you plan to provide? Minimum back-up requirement Fuel used: HSD Fuel Quantity: < 0.005 % Sulphur content Dual Fuel Generator Set capacity proposed are 2000KVA x 9Nos. + 3000KVA x 5Nos.

9.4. What passive solar architectural features are being used in the building? Illustrate the applications made in the proposed project.
About 30% of the total development will be constructed using glass, reducing the consumption of power for lighting during the day time. Daylighting and allowance for openable windows for use in comfortable months for ventilation will optimize energy usage. As the building is high-rise, care has been taken to use high performance reflective glazing that allows sufficient light transmission into the building without allowing excessive heat transfer. Given the large floor to floor heights and the fact that the typical floor plates are not deep (typically not exceeding 12-15 meters depth,) light penetration will be good and need for continuous artificial lighting is reduced.
9.5. Does the layout of streets & buildings maximize the potential for solar energy devices? Have you considered the use of street lighting, emergency lighting and solar hot water systems for use in the building complex? Substantiate with details.
50% of the external lighting which includes lighting along the driveways & landscape pathways is proposed to be on Solar. Location of these solar lightings has been designed so as to maximize its exposure to the Sun. The top two floors of the residential buildings are proposed to be on Solar Water heating systems, which would result in Energy Savings.
9.6. Is shading effectively used to reduce cooling/heating loads? What principles have been used to maximize the shading of Walls on the East and the West and the Roof? How much energy saving has been effected?
The overall design of layout buildings has adequately taken care of shading factor into consideration and will result in significant savings in energy consumption.
Maximizing the use of daylight in both common areas and within the office space is a key aspect of the design, to reduce the need for artificial lighting.
9.7. Do the structures use energy-efficient space conditioning, lighting and mechanical systems? Provide technical details. Provide details of the transformers and motor efficiencies, lighting intensity

The proposed Commercial Development has been designed with the windows placed deep in the south facing walls, which helps to shade the window to minimize direct solar gains and reduce perimeter cooling loads. Vertical Exhaust shafts are placed in each building, from where mechanical systems such as exhaust fans from individual toilets & kitchen are connected. Use of low loss transformers - total losses will be 1.19 % of the rating of the transformers Installation of meter at various locations to check the power consumption and power loss, if any. Suitable rating & size cables selection to limit the total power distribution losses less than 1 % by setting up transformer centers at applicable load centers 50% of the external lighting will be by Solar Use of VFD pumps and motors
9.8. What are the likely effects of the building activity in altering the micro-climates? Provide a self- assessment on the likely impacts of the proposed construction on creation of heat island & inversion effects?
The effects of the building on Micro-climates will be minimized by implementing the following measures
Decrease exposed surface area - Minimum ground coverage Increase thermal resistance - Roof insulation and east and west wall insulation Increase shading - East and west walls, glass surfaces protected by overhangs, fins and trees Increase surface reflectivity - Roof with Pale colour paints (SRI Paints), glazed china mosaic tiles, etc.
9.9. What are the thermal characteristics of the building envelope? (a) roof; (b) external walls; and (c) fenestration?

9.12. What is the rate of air infiltration into the building? Provide details of how you are mitigating the effects of infiltration.
Air infiltration is the exchange of air through cracks and gaps in the outside shell of a building. Infiltration increases heating and cooling costs and reduces the comfort level of occupants. Loose fitting windows and doors, cracks between the house and the foundation, and gaps around plumbing and electrical penetrations are typical sources of leaks. Although reducing air infiltration is recommended, it is not advisable to seal a historic building too tightly. This could result in a lack of adequate ventilation or, in extreme cases, sick building syndrome. Care will be taken to reduce air infiltration by meticulous construction & 30% addition fresh air will be induced as per ASHRAE.
9.13. To what extent the non-conventional energy technologies are utilised in the overall energy consumption? Provide details of the renewable energy technologies used.
