The current development in building energy efficiency towards nZEB buildings represents a number of new challenges to design and construction. One of these major challenges is the increased need for cooling in these highly insulated and airtight buildings, which is not only present in the summer period but also in the shoulder seasons and in offices even in midwinter. Resilient ventilative cooling can be an energy efficient solution to address this cooling challenge in buildings.
This webinar will present solutions of ventilative cooling in practice in residential and non-residential buildings. Peter Holzer, operating agent of IEA EBC Annex 80 Resilient Cooling of Buildings, will give an overview, and speakers from industry will demonstrate interesting ventilative cooling components.
The Air Infiltration and Ventilation Centre (https://www.aivc.org/) with support from ASHRAE and REHVA organized the webinar “COVID-19 Ventilation related guidance by ASHRAE and REHVA” held on Friday November 20th, 2020 at 16:00-17:15 (CET). The webinar presented the guidelines by REHVA and ASHRAE and also had a closer look to the similarities and differences in both guidelines.
Presentations and Speakers:
Introduction, Arnold Janssens – chair of AIVC WG COVID-19
REHVA guidance regarding ventilation, Jarek Kurnitski – chair of REHVA COVID-19 task force
ASHRAE guidance regarding ventilation, William P. Bahnfleth – chair of ASHRAE’s Epidemic task force
Similarities and differences between REHVA’s & ASHRAE’s guidance, Valérie Leprince – member AIVC COVID-19 working group & ASHRAE’s Epidemic task force
Progressing the scientific basis of indoor environmental quality is essential to understand which aspects can be better optimised to substantially reduce energy use in buildings. In recent years, IEA Energy in Buildings and Communities (EBC) international research projects have been … Continue reading →
The venticool website has now been updated to include also information from IEA EBC annex 80 resilient cooling of buildings. This is part of a collaboration agreement between INIVE, AIVC, venticool & IEA EBC annex 80. Stay tuned to be informed about all the latest findings on resilient ventilative cooling!
The EBC Annex 80 held its second Expert Meeting on April 20th and 21st as its first fully web-based meeting. Over 50 participants from 15 countries took part in three online sessions schedule to take on the large time lag … Continue reading →
