|HERS Score chart|
What's even more remarkable is that this score was achieved without using geothermal heating or solar assistance, both of which had to be eliminated due to budget constraints. It shows that with putting some extra money in quality construction (in this case the ICF walls by an experienced ICF crew) can generate significant energy savings.
If later on we want to switch to geothermal or add solar power we can still do that and reduce our energy cost even further, while it is virtually impossible (read: expensive) to redo the building envelop at at a later stage...
Thank you, Charis Homes!
