I object to the loss of energy conservation measures in new construction, in particular the change of the following specific standards:

Wall insulation – reduced R-Value from 20 or 13+5 to 15 or 13+1, and changed U-Factor from
0.057 to 0.079.

Ceiling insulation – reduced R-Value from 49 to 38, and changed U-Factor from 0.026 to 0.030.

These components of a home may not be efficiently improved following construction and improve the heating and cooling performance of a home for the life of the mortgage. The cost is easily justified as a small increment which has a proven pay-back.
