Energy Performance Score example.

In the world of home performance, we definitely like numbers. We also seem to like models that result in numerical scores, such as HERS, green point certification, and the like. The various home-rating systems have their strengths and, more often, their weaknesses, says Steve Mann in this month's article "Energy Performance Score." A major weakness is that if you reduce everything to a number, how do you explain that number to a homeowner? 


Enter the Energy Performance Score (EPS), designed to easily communicate the energy efficiency of new and existing homes to the general public. Described as a miles-per-gallon rating for homes, EPS uses normalized assumptions for occupancy and behavior, which are applied to all houses to guarantee consistency.

Read more about the EPS audit process and the program's future.


Under Pressure by Brett Dillon

CartoonWhy are energy raters and auditors not more curious about what causes the pressure test results they see? "Frankly, I find it very discouraging," says Brett Dillon, managing director of IBS Advisors, LLC and chair of the RESNET Technical Committee. "If [energy raters and auditors] understood the principles behind these tests, they could accurately assess the problem and come up with proper solutions."

Instead, we find ourselves working backward from a test result to a hypothesis. Why are we trained this way? Our industry is under pressure to improve the skills and knowledge of our workforce.

Read on to see how we can improve.
