Raters provide what to the builder (3 things) - CORRECT ANSWER - 1. Rating report
2. Conflict of interest disclosure form
3. consumer complaint process
Number of climate zones in the US - CORRECT ANSWER -8
DelMarVa in which climate zone - CORRECT ANSWER -4
3 main programs that use the HERS index - CORRECT ANSWER - 1. Energy Star
2. Challenge Home
3. HUD's programs
Heating Degree Days - CORRECT ANSWER - 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 - CORRECT ANSWER - 50 (CDD50)
What are CDD and HDD used for? - CORRECT ANSWER - 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 - CORRECT ANSWER - 100
4 steps of calculating the HERS index - CORRECT ANSWER - 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 - CORRECT ANSWER - 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) - CORRECT ANSWER - QA: ensures
best practice was followed
QC: ensures that the product was installed correctly and performs as intended
Equipment gauges must be calibrated every _______ - CORRECT ANSWER - Year
Q represents what? - CORRECT ANSWER - Heat flow (in Btu/hr)
Overhang measurements are important to - CORRECT ANSWER - Determine the window
shading
Which view shows insulation level and installation - CORRECT ANSWER - Sectional
view
HERS Index is based on these end uses - CORRECT ANSWER - Heating, cooling, water
heating, lighting, appliances (How Come WHales Like Anchovies... memory tool)
An Energy Improvment Morgage Allows: - CORRECT ANSWER - The buyer / owner to
include the cost of energy efficiency improvements in the mortgage
The measure of resistance of a material to heat flow is: - CORRECT ANSWER - R-value
Where would you find the construction details and location fo attic knee walls? - CORRECT
ANSWER - Sectional view
The Efficiency Rating of an Air Source Heat Pump in heating mode would be expressed as -
CORRECT ANSWER - HSPF (Heating Seasonal Performance Factor)
T/F
