ECBC Compliance and Energy Conservation

The project shall be employing the Whole Building Performance Method

The key Energy Conservation Measures (ECM’s) of the project –

•Local Shading Devices and Shading on account of massing

•Day light and Natural Ventilation

•Energy Efficient Lighting using LED;’s in common areas Controls for external lighting

•Energy efficient Building Envelope – SGU with shading and improved SHGC, Roof

Insulation and Light Colored Finishes

ENERGY CONSERVATION PLAN

Effective measures have been incorporated to minimize the energy consumption in the following

manners:

Maximum use of sunlight

The high efficiency CFL lamps shall be used

DG sets are controlled by PLC panel

Illumination level in different area is as per NBC

To economize on the use of energy, following main systems are proposed to be adopted:

Adequate design to limit the losses in transmission and distribution system.

Use of energy efficient devices like light sources such as true-lite fluorescent lamps and

compact fluorescent lamps.

Use of insulation on roof top to reduce air-conditioning load.

Use of capacitors at load centers to improve voltage and power factor to reduce

distributional losses and also to avoid penalty by state electricity authority.

The project, will involve uses of glass with coating of low e-value. These glass will help is

reduction of the heat intake thereby reducing the Air-conditioning load.

Suitable energy optimization is adopted during the calculation of energy load of the project. The

space heating load will be minimized using passive solar structure and suitable buildings envelop

material. Uses of compact fluorescent and fluorescent lamps will be used for all common area

and basement parking.

Roof insulation will be provided using earthen pots or thermocol on the top floor of the Building.

The U-values of the roof, external wall and glazing of the building will meet the requirements as

specified in the Energy Conservation Building Code (ECBC).

The uses of non-conventional source of energy in the construction project are as follows:

a. Solar Water Heater

The project will be installed solar panels for hot water requirements and hence, the

dependency on electricity for hot water generation can be minimized.

b. Solar Street Light

It is also suggested to use solar cell powered street lights within the project site for

conservation of electricity.

c. Use of CFL Lamps

The project proponent will use CFL Lamps which conserve less electricity

d. Natural Ventilation and Lighting

All building blocks of the project are designed with natural ventilation and natural light so

that the use of lights during day time can be minimized. All fenestration with U-factors,

SHGC, or visible light transmittance determined, certified and labeled in accordance ISO 15099

shall be adopted.

ENERGY CONSERVATION MEASURES

• Materials for Doors and window which are poor heat conductor will be used.

• Fly ash made bricks and cement will be used.

• All the roof is proposed to be insulated to minimize heat gain with 50 mm expanded

Polystyrene or equivalent material.

• CFL based lighting will be done in the common areas, landscape areas, signages, entry

gates and boundary walls etc.

• Use of solar water heater systems has been proposed for the project.

• Optimum use of skylights.

• External and basement parking lighting will be time controlled.

• DG sets shall be on auto cut and auto start controlled mechanism.

• Solar lighting is proposed for open spaces and signages.
