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 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.

Footnotes to Residential Energy Code Application for Certification of Compliance
Ceilings with attic spaces: R-30 in Zone 5 or R-38 in Zone 6 will be deemed to satisfy the
requirement for R-38 or R-49 respectively wherever the full height of uncompressed R-30 or R-38
insulation extends over the wall top plate at the eaves or the full R-value is maintained. This is
accomplished by using a raised heel or energy truss as shown in the diagram below or by using higher
R-value insulation over the plates.
R-13 + R-5 means R-13 cavity insulation plus R-5 insulated sheathing. If structural sheathing
covers 25 percent or less of the exterior, R-5 sheathing is not required where the structural sheathing
is placed. If structural sheathing covers more than 25 percent of exterior, the structural sheathing
must be supplemented with insulated sheathing of at least R-2.
Slab edge insulation must start at the top of the slab edge and extend a total of two (Zone 5) or four
feet (Zone 6). Insulation may go straight down, out at an angle away from the building, or along the
slab edge and then under the slab. A slab is a concrete floor within 1’ of grade level. See diagram
The top edge of insulation installed between the exterior wall and the interior slab may be mitered at a
45 degree angle away from the exterior wall.
Allowable Slab Insulation Configurations
A or A+ B must equal two feet in Zone 5 or four feet in Zone 6
MODULAR HOMES must be certified by the NH Department of Safety. Unless the floor insulation
is provided by the manufacturer this form must be submitted. This form must also be submitted if the
basement is to be insulated or supplementary heated space is added to the home upon or after it is set.
