GRIHA, an acronym for Green Rating for integrated Habitat Assessment,is the National Rating System if India. GRIHA has been coceived by TERI  (The Energy and Resources Institute, New Delhi) and developed jointly with the Ministry of New and Renewable Energy, Government of India.It is a green building 'design and evaluation system',and is suitable for all kinds of buildings in different climatic zones of the country.

ADaRSH , Association for Development and Research of Sustainable Habitat, is an independent platform for the interaction on scientific and adminsistrative issue related to sustainable habitats in the Indian subcontinent. It was founded jointly by TERI  (The Energy and Resources Institute, New Delhi) and MNRE ( Ministry of New and Renewable Energy , Government of India ) along with a handful of experts in the sustainibility of built environment from across the country. ADaRSH promotes GRIHA (Green Rating for integrated Habitat Assessment) as a design & evaluation tool for Green Buildings and Habitats.

The Centre for Environmental Science & Engineering at the Indian Institute of Technology, Kanpur is concieved with the specific objective of creating an interdisciplinary research facility integrating the fields of engineering , science and medicine to address environmental issues. The Centre for Environmental Science & Engineering building has been conceptualized , designed and constructed as a "building in the garden" that is sustainable and evvironment friendly. The facility has obtained a 5 star TERI-GRIHA A Green Building certification.

Green Design Features :

> Existing landscape and vegetation are largely protected and preserved.   Sustainable site planning to resources and minimize disruption of natual   ecosystem.

> Integrating the water body with design for optimal microlimate.

> Architectural design optimized as per climate and sun path analysis, achieving   reduction in energy consumption.

> Optimization of building envelope by use of insulated cavity walls,insulation of   roofand surface finishing that reflects a major solar heat.

> Efficient glazing for openings which mizimize solar grains in summer , heat loss   in winter and maximize natural dayligh.

> Roof shaded by bamboo trellis with green cover to cut direct heat gain.

> Provision of an internal court shaded by louvers that allow free air movement.

> Natural light and ventilation through skylights & ventilators in common spaces.

> Use of indigenous and recycled materials with low embodied energy.
