Numerous studies indicate that increased building energy efficiency offers the single largest opportunity for cost-effective reductions in energy use and greenhouse gas emissions. It is precisely for this reason that public policymakers worldwide are actively considering mandatory building energy labeling as a marketplace tool ...
