  • A green building is one, which uses less water, optimises energy efficiency, conserves natural resources, generates less waste, and provides healthier spaces for occupants, as compared to a conventional building.

  • EDGE Program in India

  • The IFC, a member of the World Bank Group, and the Confederation of Real Estate Developers' Associations of India (CREDAI), apex body of private real estate developers, have partnered to promote green buildings in the country through IFC’s EDGE certification.

  • A MoU was signed in the presence of Minister for Environment and Forests Prakash Javadekar on November 25, 2014.

  • The Indian Bureau of Energy Efficiency (BEE) launched the Energy Conservation Building Code (ECBC).

  • GRIHA is a rating tool that helps people assesses the performance of their building against certain nationally acceptable benchmarks.

  • It evaluates the environmental performance of a building holistically over its entire life cycle, thereby providing a definitive standard for what constitutes a ‘green building’.

  • The rating system, based on accepted energy and environmental principles, will seek to strike a balance between the established practices and emerging concepts, both national and international.

  • Its India’s first net zero energy building that has been constructed with adoption of solar passive design and energy efficient building materials.

  • It covers only 30 % of the total area, while more than 50% area outside the building is a soft area with plantation and grass.

  • The successful adoption of green building strategies can maximise both the economic and environmental performances of buildings.

  • The building has received GRIHA 5 star (provisional) rating for the following features.

  • The design allows for 75% of natural daylight to be utilised to reduce energy consumption.

  • The entire building has an access friendly design for differently abled persons.

  • With an installed capacity of 930 kW peak power, the building has the largest rooftop solar system among multi-storied buildings in India.

  • The building is fully compliant with requirements of the Energy Conservation Building Code of India (ECBC).

  • Total energy savings of about 40% have been achieved through the adoption of energy efficient chilled beam system of air conditioning.

  • As per this, air conditioning is done by convection currents rather than airflow through air handling units, and chilled water is circulated right up to the diffuser points unlike the conventional systems.

  • Green materials like fly ash bricks, regional building materials, materials with high recyclable content, high reflectance terrace tiles and rock wool insulation of outer walls have been used.

  • Use of renewable bamboo jute composite material for doorframes and shutters.

  • UPVC windows with hermetically sealed double glass.

  • Calcium Silicate ceiling tiles with high recyclable content and grass paver blocks on pavements and roads.

  • Reduction in water consumption has been achieved by use of low discharge water fixtures, recycling of wastewater through sewage treatment plant, use of plants with low water demand in landscaping, use of geothermal cooling for HVAC system, rainwater harvesting, and use of curing compounds during construction.
