Invitation to a webinar on 'Envelope airtightness measurement method and equipment - Building preparation and uncertainty estimation'

Share this Post:
Envelope airtightness is an important feature for low-energy, well-ventilated buildings. With the objective to generalize zero-energy buildings by 2020, several countries have to stimulate a market transformation for better envelope airtightness. This has been identified as a major challenge in the ASIEPI project, with several underlying issues to resolve, among them, the need to clarify the measurement protocol to complete legally robust airtightness rewards and penalties.

The objective of this webinar is to discuss proposals:
- to better define the building preparation ;
- to estimate the uncertainty in the derived quantities which are used as a reference versus a minimum requirement and/or in energy performance calculation methods.

This Webinar is a follow up of the ASIEPI project ( funded under the Intelligent Energy Europe programme. It is an initiative of the Building Airtightness Platform Europe whose aim is to be the central European information point on all aspects related to Building Airtightness.
