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 Unconditioned, basement ceiling insulated
Foundation Wall Insulation Type = N/A R-Value=
Slab Edge Insulation Type = N/A R-Value=
Rim & Band Joist Insulation Type = FG R-Value= 19
Above Grade & Walkout Walls Insulation Type = OCF R-Value= 24 Grade=1
Windows U-value = .30 SHGC = .30
Glass Doors U-value = .30 SHGC = .30
Skylights U-value = n/a SHGC = n/a
Exterior Doors R-4
Ceilings Insulation Type = OCF R-Value= 50
Blower Door Test* 5 ACH50 or better*
-----Select from list----- Meet ALL Checklist Requirements as verified by a HERS rater at pre-
drywall and final inspection
* The 2009 IECC requires a blower door test result of 7 ACH50 or lower. The number listed here requires significant improvements
in air sealing beyond the base energy code.
Mechanical Systems Specifications Used in Analysis
Heating Equipment Type: Furnace Efficiency: 90+%
Cooling Equipment Type: Central Efficiency: 13 SEER
Water Heating Equipment Type: On-Demand Efficiency: 90+%
Duct Leakage 213cfm or less leakage to the outside at final inspection
Duct Location Interior/Attic under insulation
Whole House Ventilation (ASHRAE 62.2) 89CFM
Lighting & Appliances Specifications Used in Analysis
Lighting 80% or more compact fluorescent bulbs
Refrigerator 500 kWh per year or less
Dishwasher .68 Energy Factor = 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: 60
Preliminary Improvement Over 2012-2013 v2 Massachusetts Reference Home: 15.5%
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.
