EnerGuide Energy Evaluation
EnerGuide Energy Evaluations are performed by Registered Energy Advisors. We are licensed by NRCan under the EnerGuide Rating System, which has been operating in Canada for over 30 years.
An EnerGuide Energy Evaluation is a review your home’s energy efficiency. It rates your house and illustrates the relative benefits of undetaking upgrades. We will propose how to best prioritize the upgrades.
On site we gather information on the building envelope components such as windows, doors and insulation, to assess heat loss. We also perform a Blower Door Test, which depressurizes the house and measures and locates where air is coming in or escaping the building envelope. We also review your heating /cooling, ventilation and hot water systems. The assessment takes about 2 hours.
In the office we do an Energy Modelling of your home using HOT2000 Energy Modelling Software.
This NRCan proprietary software generates 3 reports;
An EnerGuide Rating, which rates you house in terms of Gigajoules of energy used per year and indicates how it compares to a home built using today’s building code.
An EnerGuide Information Sheet, which provides a wealth of information including, how much energy is used by each component (space heating, lighting, hot water heating etc.) and where your home losses energy and how much (doors, windows, walls, air leaks etc.)
A Renovation Upgrade Report which recommends upgrades and prioritizes them. It also calculates how much cost and energy you would save based on todays energy prices.
Blower Door Test
A Blower Door Test is an intergral part of an energy Evaluation.
We set up a frame and a fan in one of your doors, start the fan and blow air out of the house. This depressurizes the house and air wants to come in through all the openings.
We take some measurements to come up with standard measure of air infiltration which we can us to reference your house to other typical houses. We also walk around the house to identify where exactly air comes in. We make it part of the report. This gives you an opportunity to fix the air leaks if you wish.
An infrared camera is an additional tool that we use to see where your house looses heat. Its eye catching if you like that kind of thing.
A thermal camera, assists us to see where heat loss happens. Its helpful during a blower door test to better see air infiltration that we may not feel with our hands. It also help us see temperature difference in wall or ceiling sections. The different colours show different temperatures. The cooler temperatures usually indicates a greater heat loss, which usually helps us determine where insulatioin is missing or less adequate
