1. Assumptions for Preliminary Home Energy Rating
CET has completed a Preliminary Home Energy Rating with the following assumptions:
a) The construction plans you have provided are accurate, including window dimensions and locations.
b) Energy features not listed below in part c will meet the prescriptive requirements of the IECC 2009.
c) The home will be built to incorporate the following energy features:
Building Envelope Specifications Used in Analysis
Basement Condition Full height basement insulated in walls, crawlspace insulated in ceiling
Foundation Walls Insulation= 2” Thermax (basement), none (crawlspace) R-Value= 13, 0
Under Basement Slab Insulation Type = Rigid Foamboard R-Value= 10
Crawlspace Ceiling Insulation Type = Fiberglass Batts R-Value= 30
Rim & Band Joist Insulation Type = 1" Rigid Foamboard + Fiberglass Batts R-Value= 18
Above Grade & Walkout Walls Insulation Type = Dense-pack Cellulose + 1/2" Rigid Exterior
Foamboard (Insulated Zip system) R-Value= 19.25 + 3.6 Grade=1
Windows & Glass Doors U-value = .29 predominant SHGC = .25 predominant
Ceilings Insulation Type = Loose Blown Cellulose (flats), Dense-pack Cellulose
(slopes) R-Value= 38, 38
Blower Door Test* 3.0 ACH50 or better

2. Preliminary Home Energy Rating Results
Based on the assumptions described above, we have calculated the following Preliminary Home Energy Rating results.
Preliminary HERS Index: 20
Preliminary Improvement Over 2012-2013 v2 Massachusetts Reference Home: 27.0%
ENERGY STAR HERS Index Target: N/A
Note that Confirmed Home Energy Rating results may vary from the Preliminary Home Energy Rating results due to
changes in building plans, energy features installed in the home, RESNET standards, software changes, and other
factors.
