Define a residential energy audit: - answer A residential
energy audit can be defined as the steps taken increase
the homeowner's comfort, safety, and health and the life
of the house. While conserving energy and saving the
homeowner money
Name & briefly explain the three broad categories of a
residential energy audit - answer 1. Screening, visual
inspections and measurements:
2. Diagnostic testing
3. Numerical analysis with reporting
Name four nationally recognized energy certifications for
home auditors & contractors - answer 1. Association for
Energy Engineers (AEE)
2. Building Performance Institute (BPI)
3. Green Mechanical Council
4. Residential Energy Services Network (RESNET)
Performing a home energy audit starts with a visual
inspection of a home & its energy systems which include:
, _________, _________, ___________, _________ - answer - building
envelope
- HVAC systems
- base load inspections
- indoor air quality
Name seven base loads, or LAMEL loads, as they apply to
a residential energy audit - answer 1. Lights
2. refrigerators
3. freezers
4. water heaters
5. clothes dryers
6. computers
7. printers
8. copiers
9. cell phone chargers
Name & briefly explain the five most common diagnostic
tests performed during a residential energy audit - answer
1. Blower door testing:- It gives the auditor insight on how
tight or leaky the home's building envelope is overall2.
Infrared scanning testing (thermal imaging camera):- in
conjunction with a blower door test for best results for
testing infiltration & exfiltration3. duct leakage testing:-
25% of the total energy losses can be blamed on air
leakage in forced-air duct systems- leakage to the outside
of the conditioned space has a much larger impact on
HVAC system performance than duct leakage inside the
space4. combustion efficiency & safety testing:- digital
