The Air Infiltration and Ventilation Centre & the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/) are organizing a workshop consisting of a series of four webinars on:

We are now pleased to announce the release of our Ventilation Information Paper no 41: Impact of wind on the airtightness test results. This paper aims to present and discuss the calculation method of standard ISO 9972 regarding the uncertainty induced by wind; gather published knowledge and determining what further research is needed on the quantification of the wind impact on airtightness tests results (including numerical simulations, laboratory and on-site measurements studies) and; give guidance for minimizing and better estimating the wind impact on airtightn

The World Health Organization (WHO) developed and published a roadmap on how to improve ventilation in indoor spaces in the context of COVID-19. The roadmap is divided into three settings – health care, non-residential and residential spaces – and takes into account different ventilation systems (mechanical or natural). The roadmap is aimed at health care facility managers, building managers, as well as those members of the general public who are providing home care or home quarantine.

The Air Infiltration and Ventilation Centre and the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/) are organizing the webinar Big data, IAQ and ventilation – part 1 to be held on April 13th, 2021 at 17:00-18:30 CET. The webinar will address the applications of IoT devices and big data in IAQ and ventilation and discuss the possibilities they provide for research.

Presentations & Speakers

The Air Infiltration and Ventilation Centre and the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/) are organizing the webinar IAQ and Ventilation Metrics to be held on April 8^th, 2021 at 09:00-10:30 CET. The webinar will discuss the road towards a robust comprehensive IAQ metric for the assessment of the performance of ventilation.

Presentations & Speakers

As already announced in the November issue of the AIVC newsletter, the AIVC board decided 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 the activities and outputs of the project with the title ‘Ventilation, airtightness and COVID‐19’. 

The Air Infiltration and Ventilation Centre and the IEA EBC Annex 86 “Energy Efficient Indoor Air Quality Management in Residential Buildings” (https://annex86.iea-ebc.org/) are organizing the webinar Building ventilation: How does it affect SARS-CoV-2 transmission? to be held on April 1^st, 2021 at 17:00-18:30 CET. The webinar will address the potential mitigating role of building ventilation in the spread of the COVID-19 pandemic. 

Presentations and Speakers:

On November 20^th 2020, the Air Infiltration and Ventilation Centre  with support from ASHRAE and REHVA organized the webinar “COVID-19 Ventilation related guidance by ASHRAE and REHVA". 406 people from 42 countries attended the webinar.

The recordings and the slides of the recent AIVC-TightVent webinar: “Building airtightness improvements of the building stock- Analysis of European databases” held on January 19^th, 2021, are now available online at:  https://www.aivc.org/event/19-january-2021-webinar-building-airtightness-improvements-building-stock-analysis-european

We are now pleased to announce the release of AIVC's Contributed Report ^o19: Indoor Air Quality Design and Control in Low-Energy Residential Buildings - EBC Annex 68 | Subtask 4: Current challenges, selected case studies and innovative solutions covering indoor air quality, ventilation design and control in residences!
