New Hampshire Energy Code EC-1 Certification No.:
Code effective September 15, 2015
Directions: Complete the “Your Proposed Structure” columns. No measurements or calculations are needed. If you at least meet the
New Hampshire Energy Code requirements, your project will be approved. Write N/A in any section that does not apply to your
project. Submit pages 1 and 2 only. If your planned structure cannot meet these requirements, consider downloading REScheck from
http://www.energycodes.gov/rescheck/download.stm and use trade-offs to prove compliance.
You are encouraged to build with higher R-values and lower U-values than you report here. The “Required R or U Values” are the worst permitted in NH.

NOTE: R-38 will be deemed to satisfy the
requirement for R-49 if the full R-38
insulation value is maintained over the
outside plates. If using only R-30 (Zone 5)
or R-38 (Zone 6), you must certify that
you’ll maintain R-38 over the plates by
checking the box below.
By checking this box, I certify that this
structure is being built with a raised energy
truss or that the full R-value of the ceiling
insulation will be maintained over the
outside plates.
