A half-day session exploring the theory and practice of achieving higher levels of airtightness - how to ‘build tight and ventilate right’
Buildings that achieve higher levels of airtightness tend to also be built and executed to a much higher quality level. While airtightness is essential to ensure thermal insulation performs to its optimum and to reduce condensation risk, it must also be combined with an effective ventilation strategy, be it by passive or mechanical means.
At its most basic, airtightness aims to eliminate any unintended gaps or cracks in the external fabric of the building. Ventilation focuses on replacing the stale indoor air with fresh outdoor air to meet the occupant’s needs. The key is to ‘build tight and ventilate right’!
More demanding building regulations not only require an improvement in individual skills but require a change in attitude to working collectively with a focused, co-operative approach to achieve compliance with regulations. Higher performing buildings, be it new build or retrofit, require good site control and communication between all trades. The production of truly low energy buildings require diligent attention to detail and co-operation between all trades involved in the construction and renovation processes. All trades should view the house as a system, rather than the sum of its parts. Trades must work as a team. All works must be co-ordinated.
The current fractured approach to building must be changed to a systems-based approach to building, in a similar manner to Passivhaus building principles and the quality standards, which are often observed on low energy or Passivhaus projects in the UK and Germany.
This seminar is part of a series of 3 events on "A fabric first approach to healthier more energy efficient new and existing buildings" and includes:
- How to Internally Insulate Solid Stone and Brick Walls
