Buildings consume 70% of the electricity and 40% of the primary energy (i.e., natural gas, coal, oil) in the United States each year. As much as 84% of that energy is wasted. Off-the-shelf, energy-efficient equipment exists that can save you 30% or more in annual energy consumption, and this guide gives you an overview of the latest technologies that can save you money. Surveys have shown that the number one reason that building owners do not invest in energy-saving upgrades of their building is financial, so this Toolkit also explains a number of ways to pay for energy efficiency upgrades that don’t require up-front capital expenditures.
