•Site Area - 2842 sq.ft.•Building Footprint - 2222 sq.ft•Total Built-Up Area -10,956.96 sq.ft.

Criteria for ratingAs defined by SVAGRIHA

Reduce UHIE (Urban heat island effect) and maintain native vegetation on siteCRITERIA 1:

Reducing hard paving and using grass pavers instead.

Trees and planters were provided to increase shade.

Terrace was a carpet of green to reduce heat gain

Water bodies to help control the heat.

Application:

Adopt passive architectural design strategies. CRITERIA 2:

Application:

Passive architectural design measures: • The project has green roofs in the form of terrace gardens. • The project has water bodies which will lead to positive effect on the spaces surrounding them during peak summer months.

Active low-energy cooling/heating systems: • Fans have been installed in the residence for better air circulation and cooling in the building. •Basement courtyard, for cooling•Clay pots installed in the roof for insulation

CRITERIA 3:

Application:

Good window designs to reduce direct heat gain and glare, while maximizing daylight

• Fenestration design to reduce heat gain- Deeply recessed balconies and by using glass of low SHGC(Solar Heat Gain Coefficient) values.

• Reduction - 62.27% which exceeds the maximum performance criteria.

• Day-lit area- 54.72% of total living area falls under day-lit zone as calculated by ECBC method.

CRITERIA 4:

Application:

Design of efficient artificial lighting systems.

• Recommended LPD, by using Compact Fluorescent Lamps and LED lamps.

• LPD Achieved - 3.81 (W/sqm)

• Specified LPD - 7.5 W/sqm

Incandescent Vs. LED CFL Vs. LED

CRITERIA 5:

Application:

Design of building envelope to reduce overall heat gain.

Fly Ash Bricks For Internal WallsACC Blocks For External Walls

Double Glazed Windows

• ACC blocks for external walls

• Fly Ash bricks for internal walls

• Double glazed windows

CRITERIA 6:

Application:

Use of energy efficient appliances.

The intent of criterion is to promote the adoption of energy efficient appliances.

All air-conditioners and fans are BEE 5 star rated.

CRITERIA 7:

Application:

Use of renewable energy on site.

• Use of renewable energy on site- installed a 3 kWp solar photovoltaic system on the roof.

• This is a grid interactive system.

Working of solar power generation system

Solar water heating systems have been installed instead of geysers

CRITERIA 8:

Application:

• Low flow fixtures

• native flora have been used to reduce the building and landscape water demand

CRITERIA 9:Rain water harvesting

Phytorid bed

Fresh water Storage tankWaste water collection tank

Rain water recharge pit

Rain water recharging: Extra rain water diverted to ground

• Project can capture 4718.12 litres of rainwater, over a period of two days. This is more than 75% of the two day building water demand – which is 3360 litres.

Application:

• Rainwater recharge pit has been created on site, along with filtration systems, to recharge the ground water table.

CRITERIA 10:

Generate resource from waste

ApplicationRotational cycle of the units: Generating manure from organic waste through installation of DailyDump composter.

Installed Compostunits

CRITERIA 12:Use of low energy materials in interior

Application:

CRITERIA 11:Reduce embodied energy of building

Application:

Old door frames were installed to avoid cutting trees

Re-used steel reinforcements

Old bricks in non-crucial areas

•Low VOC paints used.

•Vermiculite used for roof insulation

CRITERIA 13:Adoption of green lifestyle

Application:

CRITERIA 14:Innovation

Application:

•Waste water is recycled and reused through a root zone treatment facility on the roof.

•Intelligent Building Management System is being installed in the project.

All the daily requirements such as ATM, Grocery shops, Park, Pharmacy, Bank, etc. are within 5 minutes walk from the residence.

A separate home theatre room to spread awareness about green buildings is also a part of the project.

Electronic lightning controls, plus motion-sensors used for some lights.

•Massive wall for heat storage with double glazed windows are provided.

•Used of locally available materials.

With an orientation best suited to catch the day long sun, the design gains passive heat and decreases heating loads.

•High level open-able windows for ventilation.

•Photovoltaic shutters, open-able automatically or manually are used. They work as reflectors when open and insulators when closed.

•Ventilation blinds to reduce solar ventilation and cooling of room

•Warm air getting into building.

•Massive wall for heat storage with double glazed windows.

•Sashless windows to provide sunlight and protect the room from moisture

•The building is the first commercial modern structure to reduce the energy load by 40% approximately in comparison to its counterpart designs over the years.

•Folding paper blinds under glazing to reduce summer overheating and glare
