Residential Energy Ratings (CLASS 1a, 2 & 4) can be performed a number of different ways as seen below.
Most commonly we rate with NATHERS software looking to obtain a min. 6 star rating for all new homes (soon to be 7).
While this works for most, it does not work for all, it’s important to have an accredited knowledgeable assessor look at your project to ensure best practice.
The difference between a good and bad assessment can be costly once you get to build stage, unknowingly agreeing to specifications that you may not fully understand.
Our process takes you through a simple easy to understand approach where we assess the drawings supplied using either the drawing specifications or a predetermined ‘standard spec’ which then gives us a preliminary rating to discuss with you the client; so that you understand exactly what we will end up signing off.
