WHAT IS A PASSIVE HOUSE?

The term “passive house” refers to a standard for design and construction with materials that aim to drastically reduce the heating needs in homes so that larger conventional heating systems are no longer needed. Homes maintain constant temperatures and do not rely on wasteful amounts of fossil fuels, they do not need to be constantly heated and cooled, therefore passive.

 

HOW DOES A PASSIVE HOUSE WORK?

The passive house’s strategy is to reuse “free” heat to heat the home.

“Free” heat is generated by all electrical and gas appliances such as ovens, refrigerators, computers and light bulbs. The casing of a passive house building must be extremely well insulated and airtight so that this “free” heat cannot inadvertently escape from the building.

A mechanical ventilation system with an air-to-air heat recovery component is installed, which simultaneously removes fresh air and removes the same amount of stagnant air.
The stagnant air leaving the house carries the “free” heat. It passes through the heat recovery fan and transfers the heat to the incoming fresh air before leaving the building.
The cool, outside clean air enters the heat recovery fan, takes the “free” heat and goes into the home heat.
The cost of a conventional heating system can be saved, and the savings invested in better insulation, airtightness, windows, ventilation and a cheaper backup heating system.

 

WHAT IS THE ENERGY EFFICIENCY MEASURED?

Car energy efficiency estimates are measured in miles per gallon. Homes are rated for energy efficiency per kilowatt-hour per square foot per year. (KWh / ft² / yr).
This varies exclusively from the materials used in the construction and the good execution of the project.
