Various studies have shown that ductwork leakage has a major impact on energy use (i.e. increased fan energy use, heating & cooling losses etc.). However, in most European countries, it is not common to perform ductwork airtightness tests, which is probably due to the lack of awareness on the consequences of ductwork leakage. As follows, ductwork airtightness is not properly taken into account in most Energy Performance Regulations and Calculations.

This spring, a global community of changemakers will convene in Seattle to turn ideas into action at the 2019 Living Future unConference. This event brings together a diverse group of leaders – from the AEC Community, Manufacturers, Government + Non-profit, and Owners + Developers – collaborating in pursuit of transformative action. Featuring 50+ sessions and keynotes from Bill McKibben and other climate leaders, the unConference is a chance to come together and continue the momentum that we have built toward creating regenerative and healthy communities.

Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities and thereby also widen the thermal comfort range. IEA Annex 62 experts developed guidelines for an energy-efficient reduction of the risk of overheating by ventilative cooling solutions and for design and operation of ventilative cooling in both residential and commercial buildings.
