Re: Re: New Part L Revision re Applications lodged after Nov 201

To compound matters, we live in a wet climate, rather than a central European dry climate. Without climatic control on venting systems moist air is delivered from the outside directly to the middle of the house.

Also please note that the mean temperature due to Global Warming is climbing. During warmer spells such as at the moment or more particularly during the summer what happens when the house overheats? You open the window thus bypassing the air tightness requirements.

Air tightness is a black box physics experiment that works when you do not include the variable; people.
