Completing a home or building energy evaluation is a wise first step to assess the ways energy is being consumed. The energy evaluation will identify what specific measures can taken to make your building more energy efficient. The evaluation might include a walk-through check-up or inspection, use of an infrared camera, a blower door, real time energy monitors or other techniques to reveal the issue(s) and the most effective approaches. This information will help you reduce operating costs and improve performance. Energy bench-marking can be used to measuring your building's performance against other buildings in your portfolio, or it can be used to compare your building to similar buildings outside your organization.
