The Advancements in Green Buildings: Technology, Benefits, and Incentives in India
The ever-growing construction sector continues to face the challenge of aligning its growth with sustainability. Amid this, green buildings have emerged as a potent solution. Leveraging technological advancements, these buildings cater to the functional, aesthetic, and more importantly, the environmental requirements of the contemporary world.
A range of innovative technologies underpin the success of green buildings:
- Building Automation Systems (BAS): These intelligent systems optimize energy use by managing HVAC, lighting, and other elements.
- High-Performance Glazing: Innovative types of glass reduce heat gain while allowing natural light, reducing the need for cooling and artificial lighting.
- Energy Recovery Ventilation (ERV): These systems capture energy from exhaust air to condition incoming fresh air.
- Green Roofs: These roofs, covered with vegetation, reduce heat gain, manage stormwater, and provide green space.
Reducing Energy Performance Index (EPI)
The Energy Performance Index (EPI) is a crucial measure of a building’s energy consumption per unit area. Lowering this index is a key target in green building. Thanks to the above technological advancements, buildings complying with the Energy Conservation Building Code (ECBC) have significantly lower EPIs compared to conventional ones.
|Building Standard||EPI (kWh/m²/year)|
|ECBC Compliant Building||150|
|ECBC Star Rated Building||120|
|Super ECBC Compliant Building||90|
Examples of ECBC-compliant buildings in India include Cybercity in Gurugram, Godrej Bhavan in Mumbai, and Patni Knowledge Center in Noida.
Benefits to Developers
The construction of green buildings brings a host of benefits for developers:
- Improved Marketability: They appeal to environmentally-conscious buyers and can command higher rents and sales prices.
- Reduced Operating Costs: Lower energy and water use translate into lower ongoing costs.
- Regulatory Compliance: Compliance with green building standards can expedite the regulatory approval process.
