With modern buildings placing increasingly exorbitant demands on our sources of energy and
water,the time has come when the possible benefits of cutting-edge green building practices can
no longer be sidelined or ignored. In order to enhance sustainable practices pertaining to the built
environment and reduce adverse environmental impact, the existing GRIHA v.2015 rating system has
been upgraded to align with evolving global sustainability targets.
GRIHA Council is pleased to introduce the GRIHA v.2019, developed in keeping with the ongoing
advancements in the Indian construction sector and to cater to buildings of varied functionalities
and typologies. The rating continues to be in alignment with national standards and guidelines such
as the National Building Code 2016 and the Energy Conservation Building Code 2017, together with
other relevant regulations pertaining to specific topics such as waste management. GRIHA v.2019
has been structured to introduce relatively newer concepts in the design and construction sector –
life cycle assessment and life cycle cost analysis of materials, a water performance index intended
to reduce the stress on municipal supply lines, emphasis on the treatment of grey and black water,
the possibilities of self-sufficiency through urban agriculture, the integration of renewable energy
generation with optimized energy use and enhanced management of waste with a focus on the
generator’s responsibility. Additional aspects such as carbon offsets and enhanced commissioning
of systems to ensure compliance with the design intent have also been explored. For the very first
time, strategies and benchmarks for cold climates in the subcontinent have also been introduced.

Through the integration of user experience, market feedback, and ease of implementation, GRIHA
v.2019 aims to push the market towards enhanced resource efficiency. Using improved benchmarks,
this version of the rating system provides a holistic perspective on the development and operation of
a green building, thereby aiding in the assessment of its economic viability. On a broader scale, it is
hoped that this system will benefit the community at large through reduced emissions, a reduction
in stress on natural resources and improved efficiency.

I compliment the efforts of our team at GRIHA Council in putting the “GRIHA v.2019” together.
I gratefully acknowledge the support of everyone associated with the development of this rating
system and look forward to their continued guidance for its enhancement.
