Retrofitting
Building efficiency is key to cutting energy consumption. In 2007, 878 million metric tonnes of greenhouse gases were attributed to commercial buildings worldwide. Buildings account for 16 percent of world energy consumption, with a higher share in developed economies (nearly 40 percent of total energy use in the United States). While roughly two percent of commercial floor-space is newly constructed each year, and a comparable amount renovated, the majority of opportunities to improve efficiency over the next several decades will be in existing building stock, most of which are constrained by old equipment, aging infrastructure, and inadequate operations resources. Improved efficiency of existing buildings—through building retrofitting and other measures—represents a high-volume, low-cost approach to reducing energy use and greenhouse gas emissions.
Even for new buildings—constructed in compliance with modern codes requiring higher levels of efficiency—there exist countless savings opportunities in the form of improved maintenance and more efficient operation practices. Buildings are often occupied without a commissioning process to ensure performance in line with original design. The potential disparity grows over time, as improper maintenance and changes in facility operation lead to more and more wasted energy.
