Airtightness tests on 200 new houses across Canada by Michael Sulatisky Download PDF EPUB FB2
An airtightness test is a whole building test that measures how easy it is for air to leak through a building's enclosure or “skin.” In residential construction air leakage tests are often referred to as blower door tests, because these tests are most commonly conducted using a piece of equipment called a blower door (see Figure 1 below).

Cited by: Building Airtightness: Research and Practice A new standard test method in the U.S. (ASTM ) A few studies in Canada and the US have shown that log houses can also be quite air. Although there is currently no regulation that governs an acceptable level of radon in Canadian homes, Health Canada, in partnership with the provinces and territories, has developed a guideline.
The current Canadian guideline for radon in indoor air for dwellings is becquerels per cubic metre ( Bq/m 3). This guideline provides. The airtightness testing is about making the house pass the test, not about making it energy efficient.
Paul claims that his experience of testing was about quantity and not quality, getting as many houses to pass the test as possible.
“All you’re doing is effectively bodging to get it through an air test. Airtightness Tests From Barrier Sciences Group. As accredited energy auditors, Barrier Sciences Group use blower door tests to determine a building’s airtightness.
The airtightness test measures “Air Changes Per Hour”, which represents the number of times per hour that the indoor air is replaced by outdoor, external air. Improving airtightness in dwellings To avoid air leakage in new dwellings it is necessary to know where leaks might occur.
Figure 2 shows the most common air leakage paths. Many of the paths shown in Figure 2 were found in the dwellings investigated in the Energy Efficiency Partnership for Homes study, referred to earlier. Here. House Airtightness Testing And When Not To Air Seal.
House airtightness testing was made possible by the development of the blower door. The blower door measures a home’s leakage rate at the standard pressure of 50 pascals. This leakage measurement is used to compare homes with one another and set air-leakage standards.

and around the world. In hard-hit Spain, health authorities reported about Passive houses are currently the only buildings subjected to maximum airtightness levels (ACH50 House 1 is a semi-detached house, built in a traditional way using masonry walls.
The latest news from across Canada. While some government-imposed social distancing measures are being eased up among the provinces and territories, many of the checkpoints and travel restrictions. This course provides an overview of the core principles of Passive House design and building energy efficiency regulations in Canada.
It covers the history of energy efficient buildings, energy consumption data and environmental impact, case studies and the economics of creating high performance buildings.

A tiered approach is new for the national code but it is a strategy that has already been used in Canada. BC’s building code, known as the “ BC Energy Step Code,” uses the tiered approach.
It allows for the building industry to see where the codes are heading and prepare accordingly. New houses and airtightness regulations. Building regulations now sets a minimum airtightness standard for new houses of 10 m 3 /(h.m 2) @50 Pa and a recommended level of 5.
Passive house certified houses need to be below ach (roughly the same units as m 3 /(h.m 2). So all new homes have to be airtight, to some extent, to meet building.

Achieving Airtightness. Here are my dos and don’ts for achieving an airtight house: 1. Airtightness doesn’t just happen — you need a very clear airtightness plan early in the design process, and you need to stick to it. If you are serious about airtightness, work with builders and architects who know about it, or who at least want to.
ASTM E Standard Test Method for Determining Air Change in a Single Zone by Means of a Tracer Gas Dilution. CAN/CGSB Determination of the overall envelope airtightness of buildings by the fan pressurization method using the building's air handling systems.
In Health Canada conducted a two-year study of radon concentrations in homes across Canada. This study found that: These openings can be present even in well-built and new houses.
and the radon level is above the Canadian guideline of Bq/m³, Health Canada recommends that you take action to lower the level. The higher the radon. This parallel structure should prove useful to readers who build/design in several climates and use both books.

Check out my previous post for a more thorough breakdown of the testing and our rationale for decisions/assumptions. Briefly though, a Blower Door Test assesses the airtightness of a building – basically, how leaky/drafty a building is.
So Canada is building far too many houses, Rabidoux says. “We’re currently building over two new houses for every person we’re adding to the working-age population,” Rabidoux wrote in a Author: Daniel Tencer. Over all, 46, similar homes were built across Canada, during and after the Second World War, by the Wartime Housing Corporation (which became the Central Mortgage and Housing Corporation in ) Initially these homes were built to house people working in war-related : Denise Harris.
