Well I have received the energy analysis of the cottage project that I have been working on for the past couple of months (here & here). On the HERS Index (RESNET) the cottage scored a 55 versus a code compliant score of 100. It is only 3 points away from the Architecture 2030 challenge’s 2010 target of 52. Oh so close!
What is amazing about our rating is that we have more than doubled the size of the home, but we have reduced the projected energy bills by half in comparison to the existing cottage. So the client is going to save approximately $1,000 a year in utility costs by renovating the little shack. So I am now challenged to make some modifications that can bring our rating down to a 52 while cutting some cost.
