The document provides details on a residential building project in India that has been designed according to SVAGRIHA green building criteria. It describes the site area and built-up area. It then summarizes the application of each of the 14 criteria, including reducing heat gain through landscaping and passive design, optimizing daylight and artificial lighting, improving building envelope insulation, using renewable energy and energy efficient appliances, reducing water and waste, and encouraging green lifestyles.
4. CRITERIA 1:
Reduce UHIE (Urban heat island effect) and maintain native vegetation on site
Application:
Reducing hard paving and using
grass pavers instead.
Trees and planters were
Terrace was a carpet of green to
provided to increase shade.
reduce heat gain
Water bodies to help
control the heat.
5. CRITERIA 2:
Adopt passive architectural design strategies.
Terrace Garden
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.
Basement
overlooking the
courtyard
Clay pots in the ceiling
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
Water bodies
6. CRITERIA 3:
Good window designs to reduce direct heat gain and glare, while maximizing daylight
Application:
•
Fenestration design to reduce heat gainDeeply 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.
7. CRITERIA 4:
Design of efficient artificial lighting systems.
Incandescent Vs. LED
Application:
•
Recommended LPD, by using
Compact Fluorescent Lamps
and LED lamps.
•
LPD Achieved - 3.81
(W/sqm)
•
Specified LPD - 7.5 W/sqm
CFL Vs. LED
8. CRITERIA 5:
Design of building envelope to reduce overall heat gain.
Double Glazed
Windows
Application:
•
ACC blocks for external walls
•
Fly Ash bricks for internal walls
•
Double glazed windows
ACC Blocks For External Walls
Fly Ash Bricks For Internal Walls
9. CRITERIA 6:
Use of energy efficient appliances.
Application:
The intent of criterion is to promote the
adoption of energy efficient appliances.
All air-conditioners and fans are BEE 5
star rated.
10. CRITERIA 7:
Use of renewable energy on site.
Working of solar power generation system
Application:
•
Use of renewable energy on site- installed a 3 kWp
solar photovoltaic system on the roof.
•
This is a grid interactive system.
Solar water heating systems have been
installed instead of geysers
11. CRITERIA 8:
Reduction in building and landscape water demand
Application:
•
Low flow fixtures
•
native flora have been used to reduce
the building and landscape water
demand
Canna
Champa
Low flow fixtures
Reed
Song of India
Colocasia
12. CRITERIA 9:
Rain water harvesting
Fresh water
Storage tank
Waste water
collection tank
Rain water
recharge pit
Rain water recharging: Extra rain water diverted to ground
Application:
•
Phytorid bed
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.
•
Rainwater recharge pit has been created on site, along with filtration systems, to
recharge the ground water table.
13. CRITERIA 10:
Generate resource from waste
Installed Compost
units
Application
Rotational cycle of the units: Generating manure from organic waste
through installation of DailyDump composter.
14. CRITERIA 11:
Reduce embodied energy of building
Application:
Old door frames
were installed to
avoid cutting trees
Re-used steel reinforcements
CRITERIA 12:
Use of low energy materials in interior
Application:
•Low VOC paints
used.
•Vermiculite used
for roof insulation
Old bricks in non-crucial areas
15. CRITERIA 13:
Adoption of green lifestyle
Application:
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.
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.
Electronic lightning
controls, plus motion-sensors
used for some lights.

17. Flight Of Freedom
Pahalgam
With an orientation
best suited to catch
the day long sun,
the design gains
passive heat and
decreases heating
loads.
•Massive wall for heat storage with double glazed windows are
provided.
•Used of locally available materials.
18. Flight Of Freedom
•High level open-able
windows for ventilation.
•Ventilation blinds to reduce
solar ventilation and cooling of room
•Warm air getting into building.
•Massive wall for heat storage
with double glazed windows.
•Photovoltaic shutters, open-able automatically
or manually are used. They work as reflectors
when open and insulators when closed.
•Sashless windows to provide
sunlight and protect the room from
moisture
