Energy Efficiency in Residential Buildings

Picture
The residential sector accounts for almost six percent of Canada's greenhouse gas emissions. Most of these emissions come from the natural gas used to heat our homes, and from the electricity produced from fossil fuels. Reducing energy consumption in your home is not only good for the environment - it's also good for your pocketbook! We offer services in building energy assessments and building energy modeling.

​ANSI/ASHRAE/IES Standard 100 (2015)
​The ANSI/ASHRAE/IES Standard 100 Energy Efficiency in Existing Buildings​ provides comprehensive procedures to improve the energy efficiency of buildings. The Energy-Use Intensity (EUI) of a building is calculated as the annual net energy use divided by the gross floor area (expressed either as MJ/m2 or BTU/ft2). When calculating the EUI, building-energy use data for twelve consecutive months within the last 18 months is considered. The energy targets for a building depends on the climate zone in which the building is located.
Performing an Energy Audit
​In accordance with Standard 100, buildings that do not meet their energy targets are required to undergo an energy audit. As part of the audit, the historical energy use is allocated to end uses such as HVAC, lighting, domestic hot water, and electrical plug loads. Once the energy audit has been completed, the energy efficiency measures (EEMs) to be implemented are selected. The estimated energy servings for the EEMs is calculated based on historical energy use.

​The building audit report defines the actions required to achieve the energy target and the corresponding cost savings. The energy savings is expressed both in terms of dollar value (based on your personal utility rates) and in terms of energy units. AirVironment Canada's lead practitioner for building energy auditing is an ASHRAE Certified Building Energy Modeling Professional (BEMP).
