What generates 70 percent of the greenhouse gases emitted from cities like New York, Beijing, or New Delhi? Not long ago, I might have answered “cars.” But the real culprit is buildings – our homes, offices, schools, and hospitals. Many of which use electricity, water, and fuel extremely inefficiently because of the way they were initially designed.
In fact, about 40 percent of the world’s electricity is used to cool, light and ventilate buildings, even though much more efficient technology exists.
The longevity of buildings is why we need to think much more about them at the new construction phase. Decisions about building materials, insulation, and plumbing live on for decades or longer. That’s why IFC, the private sector-focused arm of the World Bank Group, is working to help builders and developers in emerging markets lock in climate-smart choices at the early design stage.
Our new certification tool EDGE, which stands for Excellence in Design for Greater Efficiencies, was designed specifically for emerging markets, where housing needs are set to grow exponentially as a result of urbanization pressures. It is Internet-based and easy to use, offering developers a range of inexpensive design choices that might otherwise be overlooked in the rush to build.
Buildings certified by EDGE use 20 percent less energy than their peers, offering long-term emissions savings and lower utility bills – a major benefit in affordable housing.
