• Shading by means of Verandah on East Facade.

• Very few Openings and high thermal mass to reject

and store the Solar heat on South facing Façade.

Roof:

Roofs will be covered with reflective china mosaic

tiles having lower U valves for lesser heat gains inside

the building.

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 and air-conditioning load

assumptions? Are you using CFC

and HCFC free chillers? Provide

specifications

Transformers:

• Automatic power factor compensating multiple

capacitor units will be provided for maintaining of

average power factor of 0.95 to have effective

savings in energy cost.

• All cables shall be derated to avoid heating during

use. This also indirectly reduces losses and

improves reliability.

• LV Power supply duly terminated at each floor

through XLPE cable with a suitable size MDB.

The project does not envisage central air conditioning

and use of chillers.

Lighting System:



48

Day light factor for towers is varying between 1.6% to

1.75 %.

Details of recommended Lux level is given as under:

S. No. Space Illumination Level (Lux)

i. Entrance 150-200-300

ii. Lifts 50-100-150

iii. Corridor, passageways, stairs 50-100-150

iv. Covered car par

v. Outdoor car park 5 – 20

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?

: Heat emission from the project can be from the following

sources:

• Heat absorbed and radiated from the paved and

concrete structures.

• Increased population for a particular stretch of land.

Heat Island Effect: Roof

• The roofs will be covered with solar panels which will

reduce the exposed roof area.

Heat Island Effect: Non-roof:

• Hard paving onsite has been reduced to the best

possible extent.

• About 12.54% of the area will be under landscape,

which will mitigate heat island effect.

9.9 What are the thermal

characteristics of the building

envelope? (a) Roof; (b)

external walls; and (c)

fenestration. Give details of the

material used and the U-values

or the R values of the

individual components.

The building materials were selected with characteristics

that limit heat ingress into the inside of the building will

be minimized.

9.10 What precautions & safety

measures are proposed against

fire hazards? Furnish details of

emergency plans.

Essential fire safety measures will be installed into the

building to ensure the safety of the occupants within the

building in the event of fire or other emergency.

The entire building will be designed as per NBC-2005 of

India pertaining to fire-hazards.

Hazard classification as per the NBC-2005, Part IV-Fire

& Life Safety:

� Group A, sub division A-4: Buildings above 45 m in

height but not exceeding 60 m.

Minimum fire fighting requirement (as per NBC 2005

Part IV Table 23) will be provided in the project. The

same is tabulated as under:

S.No. Item Group Housing

[ Height >45 m but <60 m]

1. Fire extinguisher Required

2. Hose reel Required

3. Dry riser Not Required

4. Wet riser Required

5. Down comer Not Required

6. Yard hydrant Required

7. Automatic sprinkler system Required

8. Manually operated fire alarm system Required

9. Automatic detection & alarm system Not Required

10. Underground water tank 75000 litres

11. Terrace water tank 10000 itres

12. Pump capacity for pump near underground static water storage

tank (Fire Pump) with minimum pressure of 3.5 kg/cm2 at terrace

level

One electric and one diesel

pump of capacity 2280 l/min

and one electrical pump with

capacity 180 l/min

13. At the terrace tank level with minimum pressure of 2.0 kg/cm2

Not Required

Safety measures:-

• Proper fire-exits and exit-signage will be provided.

• Fire-extinguishers of appropriate type will be placed on



50

a readily accessible place and will be maintained

accordingly.

9.11 If you are using glass as wall

material provides details and

specifications including

emissive and thermal

characteristics.

: Glass is not used as wall material except for the windows.

9.12 What is the rate of air

infiltration into the building?

Provide details of how you are

mitigating the effects of

infiltration.

: Building is designed with positive pressure.

9.13 To what extent the non-

conventional energy

technologies are utilized in the

overall energy consumption?

Provide details of the

renewable energy technologies

used.

: The solar energy will be utilized efficiently for-

• 10% energy demand will be reduced by preheating the

water by using Solar geysers.

10 ENVIRONMENT MANAGEMENT PLAN

The Environment Management Plan would consist of all mitigation measures for each item

wise activity to be undertaken during the construction, operation and the entire life cycle to

minimize adverse environmental impacts as a result of the activities of the project. It would

also delineate the environmental monitoring plan for compliance of various environmental

regulations. It will state the steps to be taken in case of emergency such as accidents at the site

including fire.
