Case studies of GRIHA registered/rated buildings 49
2.1.4 Building design and energy
The building design has also included the existing site features, such as, the visual linkages with
historical monuments, solar geometry, and so on. Due to high density planning requirements, the
design did not permit optimum orientation for all apartment blocks. As a result, the apartment
blocks have equal exposure towards all cardinal directions. However, the critical facades are shaded
and have high performance glazing to negate impact of direct incident radiation. The buildings
are fully compliant with the Energy Conservation Building Code 2007. Several energy effi ciency
measures such as roof insulation, high performance glazing, energy effi cient lighting and variable
refrigerant volume (VRV) based air conditioning system have been provided to reduce the energy
consumption of the apartments signifi cantly.

2.1.5 Renewable energy
Solar photovoltaic system has been proposed to meet 10% of total energy requirements for internal
lighting. 31% of outdoor lighting has been provided through solar energy. Solar hot water systems
have been provided to meet part of water heating needs.
2.1.6 Other features
Waste water recycling and solid waste management for the entire campus has been planned by the
Delhi Jal Board at a macro level for the village as well as adjoining properties.
