This document summarizes the sustainable features of a building called HAREDA Construction Journey. It has an energy consumption reduction of 72% compared to benchmarks and installed 42.5KW of solar PV. It received a 5-star rating from GRIHA. Sustainable designs include south-facing windows for sunlight, solar chimneys for ventilation, and minimized shadows on neighbors. Water consumption is reduced 70% by efficient fixtures and rainwater harvesting. Energy is reduced through daylighting, solar chimneys, and 42.5KW of solar power installed. Landscaping uses trees and vines to moderate temperatures.

1. HAREDA
Construction Journey

2.  Energy consumption reduction compared to GRIHA
benchmark: 72%.
 Renewable Energy: Rated capacity of solar PV installed
on site is 42.5 KW.
 GRIHA provisional rating: 5Stars (scored 90 out of 92
applicable marks)

3. Sustainable Site Planning
 East and West
windows are oriented
south to have easier
sun control through
shading devices.
 The south face has
solar chimneys to aid
ventilation in some of
the non a/c spaces.
 The height of
building is such that
the shadow on
neighboring buildings
is minimized.

4. Reducing water consumption
 Annual reduction in water consumption by
70% by using efficient fixtures.
 6.25 lac Liters rain water storage tank has
been designed in the basement to collect
water from the roof and courtyard.
Percolation pits designed along the driveway
to collect rain water from the driveway, the
overflow of which has been directed to the
municipal sewer.
 Rain water collected is treated by pressure
sand filter, activated carbon filter and
chlorinated to further use it for drinking
purpose, HVAC plant and horticulture.

5. Reducing energy consumption
 East and West windows are oriented south, these
windows help day light the office spaces on those faces.
 Central court and single loaded corridor help provide
visual comfort by natural light.

6. Reducing energy consumption
 The south face has solar chimneys to aid ventilation in
some of the non a/c spaces.
 Misting done in the courtyard to cool the ambient air which
is sucked into the building through solar chimneys. The
achieved internal air Relative Humidity range from 60% -
75 %

7. Renewable energy
technologies installed on site
 42.5 KW SPV plant (with 5 kW B.I.P.V installed above
the courtyard) has been installed.
 Solar water heater for capacity of 600litres installed for
cooking and bathing purpose.

8. Landscaping
 Deciduous trees are planted on the West
face of the building to allow winter heat gain
while keeping the summer sun out.
Evergreen bushes are planted on the North
and East to cool the air as it enters the
building.
 Climbing evergreen creepers are proposed
on the south face and inside the building to
keep the summer heat gain in check.
