 The EnerGuide for Houses program has been replaced with the new ecoENERGY Retrofits Initiative.
If you had an energy evaluation done before EnerGuide for Houses was discontinued on May 12, 2006, you have until March 31, 2007 to complete your retrofits, schedule a post-retrofit evaluation and apply for a grant under that program.
It is important to do this now because audits done under the EnerGuide program before May 12, 2006 will not qualify for the ecoENERGY program and you will have to start the process over again. That means an additional $375 to conduct a new audit plus another $150 to conduct the post.
You may want to consider a loan for retrofits up to $4,000. Even over a year, your interest charge would be LESS than paying the $375 for a new energy audit*.
Please contact Green$aver to see how we can help you meet the March 31, 2007 deadline. Call 416-203-3106.

Building Simulation Software
A building energy simulation software allows an energy advisor to create a
computer model of your house and simulate its energy performance. The
software uses average weather data of the region, where your house is
located, in order to perform a heat loss calculation, and is able to review
upgrade scenarios and calculate potential savings.
Heat loss Calculation
In order to do a heat loss calculation an energy advisor models your house
in a building energy simulation software taking the geometry, orientation,
insulation levels, number and type of windows and doors, efficiency of the
heating system, and the air leakage rate of a house in to account. The
results shows how much heat is been lost through various parts of the house,
like the basement, main walls, windows and doors, roof, and cracks and leaks
in the house. With this information you will be able to prioritize your
retrofit measures.
Blower Door Test
A blower door test uses a large exhaust fan to depressurize a house, and
enables an energy advisor to calculate the air leakage rate of the house.
Put more simply, a blower door test tells you how much warm air (energy)
leaks out of a building during winters and how much cold air replaces the
lost warm air in the form of cold drafts. Besides calculating the air
leakage rate of a house, the advisor can also pinpoint where these leaks are
located.
Thermal Imaging
Thermal images made with an infrared camera record the temperature
variations of the building envelope, visualizing where heat is escaping
through the house envelope, where there is missing insulation and enabling
an energy advisor to pinpoint and assess problem areas in an uninvasive way.
