WHAT IS THAT?

The passive house

THE CONCEPT

In a nutshell

When we talk about a passive house, conceptually, what is the reference? A house that passively uses optimal solar radiation, internal heat sources and heat recovery, minimizing the need for external appliances to make it habitable year-round. Imagine being constantly exposed to a perfectly ambient temperature, 365 days a year. No need for coats or multiple seasonal wardrobes, no need to always struggle in search of the most comfortable place or position…

It is this standard that guides the design of so-called passive houses. This type of construction aims to reduce the energy consumption of heating in winter by up to 90% so that its inhabitants have to resort as little as possible to artificial mechanisms of temperature adjustment. In doing so, a passive home reduces the pollution that results from the usual energy consumption, simplifies the interior layout by minimizing the need to use utilities such as radiators and air conditioners and improves the overall comfort of your living space by keeping it at an optimal temperature in every nook and cranant. Similarly, for warmer weather, shadow strategies are designed to avoid overheating, thus reducing the energy consumption of air conditioning.

OPERATION

How does it work?

One of the most effective ways to reduce energy consumption is to reduce thermal energy losses due to poor insulation. An optimal insulation process is therefore the basis of a passive house, and this process naturally includes consideration of thermal bridges, the points other than the walls through which thermal energy tends to escape. The overall ventilation and waterproofing of the structure are also of paramount importance to buildings to avoid air passages that interfere with heat conservation and the comfort of your home.

PRINCIPALES

Certifications

Bioclimat houses are much more than beautiful, optimally insulated homes. They meet standards that qualify them for the following prestigious certifications:“Passivhaus Institute”(PHI), “Passive House US”, (PHIUS),“Leadership in Environmental Design”(LEED) and Novoclimat. Our know-how and compliance with the standards that lead to these certifications allow us to design homes that offer energy savings in heating and air conditioning ranging from 40% to 90% compared to standard residential consumption.

QUÉBEC PASSIVE BUILDING MEMBER

How does it work?

A passive building benefits from various design measures. It passively and optimally uses solar radiation, internal heat sources and heat recovery, to reduce the energy consumption associated with heating the building in cold weather. During the warmer months, similar design measures, such as strategic shading, keep the interiors cool and comfortable and thus reduce the energy consumption required for air conditioning. These passive measures can be so effective that conventional heating and cooling systems can be completely switched on, even during the harshest winters and heat waves, thereby reducing the ecological footprint of buildings.
