This document provides information about the Indira Paryavaran Bhawan building project in New Delhi. It summarizes that the building was constructed as a net zero energy green building for the Ministry of Environment and Forests. It achieved several sustainable design features like 40% energy savings, zero electricity billing, 55% water savings, and the largest rooftop solar power system of 930KWp on a multi-story building, making it the first government building to receive both 5-star GRIHA and LEED Platinum ratings.

• Wider Front Setback (22m) to protect front tree line
• Preserve the integrity of the green street
• Preservation of the local ecology, Tree Cutting approvals for 46, but only 19
cut
• - 11 Trees Transplanted
• - Excavated Soil reutilized at other construction sites and the Zoo
•The IPB office building for the ministry of
environment and forests has been planned in
2 parallel blocks facing the
•north south direction, with a large linear
open court in the centre.The Building blocks
create a porous block form to optimize
•air movement throughout the site and the
N- S orientation allows for optimum solar
access and shading.

Optimize building design to reduce conventional energy demand.-
• energy efficient light fittings to reduce energy demand
• part condenser water heat rejection by geothermal mechanism. this will also help in water conservation in
cooling towers for hvac system
• variable chilled water pumping system through vfd.vfd on cooling towers
fans and ahu.
• pre cooling of fresh air from toilet exhaust air through sensible & latent heat energy recovery wheel
• entire hot water generation through solar panels.
• maximum daylighting
• regenerative lifts.
• use of lux level sensor to optimize operation of artificial lighting.
• solar powered external lighting.
Optimize energy performance of building within specified comfort limits-
• Reducing energy consumption (compared to GRIHA benchmarks) while maintaining occupant
comfort:
• For achieving visual comfort:
• Direct line of sight to the outdoor environment to vision glazing for building
occupants for more than 90% of the occupied spaces.
• Avoiding Deep floor plates to create maximum daylighted spaces.
• Landscaping planned with native species and water body features in central
court and all around the building.
• For achieving thermal comfort:
• All circulation spaces or passages were naturally ventilated / shaded / not air
conditioned.
• Energy Efficient Chilled beam based Cooling system proposed together with
condenser water cooling through ground pipes.
• Openable windows were proposed in conditioned areas to be able to utilize
favourable outdoor conditions.
• Insulated Walls through using an integrated AAC + Rockwool combination
together with high efficiency DGU’s and UPVC.

• There are 180 vertical bores at the
Depth of 80 meter all along the
Building Premises. Minimum 3
meter distance is maintained
between any two bores.
• Each bore is lowered with HDPE
pipe U-loop (32mm outer Dia.) and
grouted with Bentonite Slurry.
• Each U-Loop is connected to MS
Header Pipe(100mm Dia.)which
finally joins the Condenser Water
Line in Plant Room.
• Condenser hot water is
sent at 100°F (37.8° C) &
back at 900 F (32.2° C).
Rejection capacity, so all together
160 TR of Heat rejection is
obtained without using a cooling
tower.
• Enormous water saving since no
make up water is required.
• Make up water pumping &
treatment cost get eliminated.
• Saves cooling tower fan energy.
