water management on site is very efficient in terms of reuse of waste water and less utilisation of potable water in construction. 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 efficiency measures such as roof insulation, high performance glazing, energy efficient lighting and variable refrigerant volume (VRV) based air conditioning system have been provided to reduce the energy consumption of the apartments significantly. 2.1.5 Renewable energy Solar photo voltaic system is proposed to meet the 10% of total energy requirements for internal lighting. 31% of outdoor lighting is provided through solar energy. Solar hot water systems are provided to meet part of water heating needs. 2.1.6 Other features Waste water recycling and solid waste management for the entire campus are being planned by the Delhi Jal Board at a macro level for the village as well as adjoining See also 2010 Commonwealth Games Concerns and controversies over the 2010 Commonwealth Games References External links BBC photos illustrating the Athletes' village construction controversy Official site Village 2010 Commonwealth Games Village Buildings and structures in New Delhi
