Today, more than half the world’s population lives in cities, a figure that is forecast to rise to 70% by
2050. Cities are engines of economic growth, generating approximately 85% of global GDP. Rapid
urbanization and increased consumption have led to economic growth in many parts of the world
but have also created unprecedented environmental degradation and socio-economic issues.
As per international commitments, India plans to reduce its energy intensity by 33%–35% by 2030.
In this regard, ‘green buildings’ play a crucial role as they are synonymous to both sustainable
construction and assured high performance. GRIHA–with its commitment to the intended nationally
determined contributions (INDCs)–has been instrumental in promoting good practices and
innovative solutions to enhance resource efficiency in the building sector. I am delighted to inform
that GRIHA has rated nearly 300 projects, amounting to approximately 71 million ft of built-up
area with an average reduction of 45% in energy demand, 45%–90% reduction in water demand
(depending on the seasonal variation), and up to 60% reduction in waste being sent to the landfills
compared to conventional buildings.

In the last few decades, green construction technologies, materials, and practices have evolved. Not
only have they become environmentally responsible but these also promote resource efficiency
throughout the building’s life cycle stages: planning, designing, construction, operation, maintenance,
renovation, and demolition. Keeping abreast with these advancements, GRIHA Council is launching
its new version: GRIHA v.2019 to ensure that the upcoming buildings are conceptualized, planned,
designed, and constructed sustainably. GRIHA v.2019 is introducing improved parameters for
an array of building typologies such as green infrastructure, life cycle assessment, life cycle cost
analysis, materials for external site development, water self-sufficiency, and systems commissioning
to provide a holistic assessment of green infrastructure, to further reduce environmental impact,
and to broaden the realm of building sustainability in India. It has been our continuous endeavour
to accelerate the greening of upcoming buildings while endorsing an amalgamation of modern
and innovative green technologies with deep-rooted traditional knowledge. I acknowledge the
contribution of the technical advisors, who provided their valuable insights, and my team for their
persistent efforts. The new version will benefit multiple stakeholders associated with the building
industry in adopting and implementing integrated greening solutions. I urge the stakeholders for
large-scale adoption of GRIHA v.2019 to incrementally increase the green building footprint across
the nation.
