HVAC Savings Estimator Tools

Proposals for energy efficiency measures are more likely to be approved if they contain statements and/or data about the benefits that the customer will realize. The HVAC value proposition includes such benefits of comfort, productivity, reliability, indoor air quality, some of which are difficult to quantify. HVAC efficiency measures can and often do contribute to the above list of benefits, but they add "lower utility bills" which can be quantified within reason. It is our hope this directory of estimation tools will help improve your proposals, whether you are a contractor or a facility manager making a sale to your management.
