While most people are quick to blame cars and their omission as the reason for global warming, the true culprits of greenhouse emissions is in fact buildings, that are responsible for 48%. Transportation is only responsible for 27% of emissions with industry trailing at 25%.
Buildings also account for 76 percent of all electricity generated at power plants. It is estimated that by 2035 a surprising 75 percent of all buildings will either be rebuilt or undergo massive renovations. This is both a tremendous opportunity to employ green (eco-friendly) design principles on a wide scale and a dangerous proposition if such principles are NOT made a priority.
Buildings have a life span of 50-100 years, and, if current trends continue, annual energy consumption will increase 37 percent, while greenhouse gas emissions will increase by 36 percent over the next 20 years.
