S SUSTAINABILITY INTERVENTIONS
One of the critical aspects of the project was the zero
tree-cutting goal, which has been successfully achieved
through an optimized plan of permissible built volume with
a 100% naturally ventilated central spine. The presence of
lush foliage helps bring down summer temperatures
through transpiration cooling. Moreover, the design of the
school incorporates a series of passive cooling measures
that reduce ambient temperatures within the building by up
to 15 degrees.
The north-south orientation for minimal solar exposure acts
as an effective self-shading component allowing the
auditorium to buffer from solar gains. Summer winds
travelling along the northwest-southeast direction are
harnessed and redirected over the stepwells to improve
thermal comfort during highly humid months. Landscaped
courtyards enhance the cross-movement of fresh air within
the building and reduce temperatures through stack
effect. Brick cavity walls, terrace gardens, and cantilever
projections further reduce heat gain. The building is
partially sunken, offering thermal banking and serving as an
acoustic buffer from the adjacent main road.

Shaded courts help in activating the social engagement
zones
The courtyard planning, incorporation of lightwells and
thermal buffering, and the integration of greenery
collectively reduce mechanical energy dependencies and
optimize resource consumption, resulting in 100% of the
academic area being Net Zero on energy (5,750 sq.m.
roof area is provided for solar farming) with an EPI of
≤58kWh/sq.m./yr compared to the ECBC benchmark of
90 kWh/sq.m./yr.
