While green buildings, by their most obvious definition, address environmental impacts, they also have wide implications for human health, safety and productivity. Well-ventilated green schools can reduce instances of asthma in students. Green offices with day lit spaces boost employee productivity and attendance. Patients heal faster in green hospitals with views to nature.
On Monday, Sept. 17, a chorus of voices from around the world spoke out in support of “Green Buildings for Great Communities,” the theme of this year’s World Green Building Week, hosted by World Green Building Council. Green building councils from 90 nations organized hundreds of events to educate the public about the health, environmental and economic benefits of sustainable design and construction.
CHF International (Cooperative Housing Foundation), which serves millions of people in low- and moderate-income communities around the world, hosted a panel in partnership with the U.S. Green Building Council (USGBC) called “Cities and Climate Change Adaptation: What We Can Learn About Resilience from Those Living on the Edge.” The panel featured Judy Baker, lead economist in the Urban Practice at the World Bank Institute; Brian English, director of program innovation for CHF International; Aram Khachadurian, an international development consultant; Helen Santiago Fink, urban climate change advisor for USAID; and Janice Perlman, an independent scholar, teacher and consultant, who discussed resiliency in the built environment and its role in addressing the plight of the urban poor.
They inhabit two different worlds—buildings and climate change—both outside and within the World Bank. It should not be that way as the building sector could be central to both mitigation and adaptation efforts.
Buildings are important for climate mitigation because they account for about 30% of global energy consumption and greenhouse gas emissions. According to the International Energy agency (IEA), energy use in this sector is expected to increase globally about 30 % over the next two decades if recent trends continue; however, the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report concludes buildings offer by far the largest potential source for low cost reductions in CO2 emissions. The World Bank has many projects and analyses addressing this opportunity including a recent ESMAP (Energy Sector Management Assistance Program) report on the benefits and obstacles to effective building codes. These could address over 60 % of building energy use but remain weak and often unenforced in most Bank client countries.
