City-wise Analysis
Southern cities (Bengaluru, Chennai, and Hyderabad) account for 58% of the total green stock pan-India. Bengaluru accounts for the highest, 172 Mn sq ft, green stock amongst the top seven cities of India. Chennai accounts for the highest percentage share, 83%, of green stock out of the city’s total Grade A stock.
Despite having the lowest stock for Grade A office buildings in pan-India, 62% of the area is green-certified in Kolkata. On the other hand, Pune has the lowest percentage, 56%, of green-certified office buildings despite the prominence of MNCs in city leasing.
Built-up Area-wise Analysis
Grade A office buildings with a built-up area of less than 5 lakh sq ft account for 47% of the total number of green-certified buildings. On the other hand, office buildings with a built-up area of more than 10 lakh sq ft account for only 19% of the total number of green-certified buildings. Despite this, 90% of the total projects within this category still qualify as green buildings, showcasing a strong focus on sustainability. Notably, green certification is rare in office buildings with a built-up area of less than 1 lakh sq ft. This signifies lower preference for sustainability practices amongst small and medium-scale developers and occupiers.
