WHAT IS AN ENERGY AUDIT?
An energy audit measures the fuel economy of your
home to improve its performance.
Our typical client will save 25% on their utility bills, while some
will reduce their bills by 100%! Through virtual energy models
and ultra-high tech equipment, Emotiv quantifies energy
leakage and evaluates the economic paybacks of various
remedies. Once corrected, systems will save dollars and bring
the added benefits of a healthier, comfortable, more efficient
building.
Which is a better investment- $20,000 on new windows or
$3000 on basement insulation?
Should you install a new furnace or supplement your old one
with a heat pump?
AUDITS INCLUDE
- Blower Door air leakage test (see pictures below)
- Infrared images of walls, ceiling and trouble zones
- Whole-home energy inspection
- Pre-audit interview and questionnaire
- Analysis of past utility bills
- Personalized report of energy findings
- Financial analysis that prioritizes upgrades based on
expected comfort and return on investment
- ENERGY STAR rating

A Blower Door, shown to
the right, measures a
home's air leaks. It is a
powerful fan that pumps a
huge volume of air out of
the house. Then we allow
the house to regain its air
pressure by naturally
infiltrating all cracks and
holes. This tests allows us to
quantify and pinpoint air
infiltration points, air
exchange rates and
dollar-escape routes. Some
infiltrations are economical to
fix and others are not.
An infrared scan is for pinpointing abnormally
hot/cold/moist zones, energy escape routes, and structural
anomalies that are usually invisible to the naked eye. The
blue areas shown above the window on the right indicate
cold spots due to infiltration near a roof overhang.
Do you really need new
windows? This older home
has brand new widows,
but notice the dark (cold)
spots around the window
frame and along the floor.
Combined with the blower
door, even in the
summer, we can get a
good idea of the source of
cold winter drafts and
dollar escape routes.
