SPECIAL FOCUS: GREEN BUILDINGS & SUSTAINABLE CONSTRUCTION neighborhoods. New high-rise residential, Globally, economic forces were cited in the “Green technologies may be slightly higher communities and mixed-use development SmartMarket Report as the most important in cost compared to existing materials but are expected to be the top three sectors drivers for many of the countries surveyed. show immense reduction in running cost for green building growth in India. Te The report found that green buildings or maintenance cost .Our study and client report, conducted in nearly 70 countries, ofer signifcant operational cost savings feedback suggests that market is ready to also demonstrates that global green building compared with conventional buildings.

International business leaders and Heating Ventilation Air Conditioning independent of the electric grid. It not only policy makers recognise that a commitment (HVAC), water & waste recycling, and saves energy, but also prevents additional to transforming the built environment is green technologies are the key enablers to greenhouse gas emissions. A zero-energy crucial to addressing major environmental building sustainable structures. Intangible design utilises solar cells and panels, wind challenges.” benefits of green buildings include: turbines, and biofuels, among others, to “Te growth of LEED refects its global enhanced ventilation, better views, and day provide for the building’s electricity and adaptability as the world’s most widely used lighting which signifcantly improve the HVAC needs. and recognized system guiding the design, health well-being and productivity of the In the same vein as zero-energy buildings, construction, operations and maintenance occupants. Te construction of buildings it is important to achieve net-zero water use of green buildings,” adds consumes large volumes of resources, in buildings, by having water-conservation Mahesh Ramanujam, COO, which is why integrating biodegradable, fxtures, rainwater harvesting and greywater USGBC, elaborating that recycled and sustainable materials makes reuse via recycled water. With buildings “LEED is a critical tool in a huge diference. Biodegradable materials using 13.6 per cent of the world’s potable creating structures that like natural paints, which are void of water, or 15 trillion gallons per year, systems mitigate greenhouse gas VOCs typically found in their traditional designed for water efciency are targeted to emissions; create healthier counterparts, eliminate indoor pollution and lower water usage by 15 per cent.
