HERS RATER EXAM PRACTICE
TEST
A HERS score can be used for which of the following?
A) LEED for Homes
B) Energy Efficient Mortgages
C) National Association of Home Builders
D) All of the above - ANSWERS-D) All of the above
Raters provide what to the builder (3 things) - ANSWERS-1. Rating
report
2. Conflict of interest disclosure form
3. consumer complaint process
Number of climate zones in the US - ANSWERS-8
DelMarVa in which climate zone - ANSWERS-4
,3 main programs that use the HERS index - ANSWERS-1. Energy
Star
2. Challenge Home
3. HUD's programs
Heating Degree Days - ANSWERS-total number of degrees colder
than base temperature (HDD65) during the "heating season"
Ex) if temp for 1 hr is 55, then 65-55 = 10 heating degree days for that
1 hr
Ex2) next hour temp drops to 48 then 65-48 = 17 HDD for that hour
and over that 2 hours we "picked up" 27 HDD
Usual base temp for Cooling degree days - ANSWERS-50 (CDD50)
What are CDD and HDD used for? - ANSWERS-Used to estimate
amount of energy needed to cool (CDD) or heat (HDD) a homes
during the cooling (CDD) or heating (HDD season)
The Reference Home is where on the HERS Index - ANSWERS-100
4 steps of calculating the HERS index - ANSWERS-1. purchased
energy fraction (PEF = (total E use - onsite power production) / (total
E use)
, 2. (rated home heating x cooling x DWH x lights x appliance
MBtu's)/(reference home h. x c. x DWH x L. x appliance MBtu's)
3. ^result is multiplied by PEF
4. ^result is multiplied by 100
3 types of ratings - ANSWERS-1. projected rating (no certs rewarded)
2. confirmed rating (used for certificated)
3. sampled rating (sampling) (not for certifying any individual home)
(method for shortcutting energy verification for large production
projects) (generally not ideal process)
QA (quality assurance) vs. QC (quality control) - ANSWERS-QA:
ensures best practice was followed
QC: ensures that the product was installed correctly and performs as
intended
Equipment gauges must be calibrated every _______ - ANSWERS-
Year
Q represents what? - ANSWERS-Heat flow (in Btu/hr)
