TightVent Europe and the Air Infiltration and Ventilation Centre are organizing the webinar "Building airtightness improvements of the building stock - Analysis of European databases" to be held on Tuesday January 19^th, 2021 at 10:00-11:15 (CET).  The webinar aims at presenting three major European databases (in the UK, Flanders and France) and also at comparing their structures and their measurement data acquisition protocols. Weaknesses and strengths in the different aspects of the existing database setups will be identified.

The 17^th issue of the venticool newsletter is now available! Specific contents include:

CIBSE initially published COVID-19 Ventilation guidance on 9^th May, followed by Version 2 on 12^th May and Version 3 on 15^th July, in response to the CIBSE position, taken in April, that there was the potential for airborne aerosol transmission of SARS-CoV-2. Version 4 was published on October 23^rd.

This guidance adopts a precautionary approach with the objective of ventilating spaces as much as reasonably possible with outside air as one measure to reduce transmission risk.

The AIVC board decided in their last (online) meeting of September 2020 to start a project to collect, discuss and disseminate information about COVID-19 in relation to ventilation and airtightness. A working group was created to define and carry out the project, with the title ‘Ventilation, airtightness and COVID-19’.  The first special issue of the AIVC newsletter is a first outcome of the project.

Highlights of this newsletter:

The Air Infiltration and Ventilation Centre with support from ASHRAE and REHVA  is organizing the webinar "COVID-19 Ventilation related guidance by ASHRAE and REHVA" to be held on Friday November 20th, 2020 at 16:00-17:15 (CET).  The webinar will present the guidelines by REHVA and ASHRAE and will also have a closer look to the similarities and differences in both guidelines
