Instructions: Write your initials in each applicable box.  If an item
does not apply to the home, write “n/a”.  Raters should attempt to
inspect as many critical items as possible but may delegate a
builder’s representative to verify and initial up to six (6) Thermal
Bypass items (numbered items on the first page of this checklist).  If
the builder verifies any item, they must sign the second page of this
checklist.  Every line must contain at least one set of initials or
“n/a”.

Qualified Homes Codes and Standards Information.” 

 Only applicable to homes in Climate Zones 4 and 5.  Homes with heat
pumps in Climate Zones 6, 7 and 8 cannot be qualified using the
Prescriptive Path (BOP), but can earn the label using the ENERGY STAR
Performance Path requirements.

 Efficiency ratings not applicable if ENERGY STAR qualified water heater
is installed to comply with Lighting and Appliances requirement.

 Can use instantaneous water heating system or an indirect storage
system with a boiler that has a system efficiency of ≥ 85 AFUE. Homes
with tankless coil water heating systems cannot be qualified using the
Prescriptive Path (BOP), but can be qualified using the ENERGY STAR
Performance Path.
