There is no doubt that, as part of this tendency to move to nearly zero energy buildings, in most climates buildings have to become more airtight. Should there be specific airtightness requirements? If so, what level is to be required? Should there be a minimum level of air leakage? This is the context for this project regarding the ‘philosophy about airtightness requirements’.

Project Outcomes
