Airtightness is one of the fundamental building blocks in high-performance construction. If an assembly is airtight then air leakage, the uncontrolled inward or outward movement of air through gaps, cracks, holes, splits and tears, is reduced to a minimum. In high-performance construction, a continuous air barrier separates the interior conditioned space and the exterior environment. Some wall penetrations in this air barrier are unavoidable in order to facilitate the supply of key...

This article explains how ventilation reduces risks of disease transmission, summarizes guidelines to support schools to reduce the risk of Covid-19 transmission by using effective ventilation.

Fire safety should be a top priority when planning any type of construction. Greater emphasis on the structure and fire-resistant certified materials is important for both the roof and the walls to achieve the maximum level of protection against fires, especially in new buildings.

As the world battles with the crisis that is global warming, one way those of us in construction can help is by building more efficient low energy buildings. The cornerstone of a low energy build is making sure you get the airtightness right! The more airtight the building the less energy that building is likely to consume. However, one unintended consequence of making our buildings more and more airtight is...
