How to be ‘smart’ about indoor air quality

BESA hosted an international webinar on the use of smart ventilation to tackle indoor air quality in partnership with the CIBSE ASHRAE Group.

Global IAQ authority Max Sherman, who is senior scientist at the Lawrence Berkeley National Laboratory in California, explained how occupancy-based control strategies could achieve better indoor conditions and reduce energy use.

A’ dumb’ approach that simply has ventilation working continuously in the background does not directly address the prevailing conditions and fails to meet new standards for energy efficiency, said Professor Sherman.

He explained that a more harmonious relationship between IAQ and energy consumption can be achieved by being smarter about how and when ventilation occurs, which stems from an understanding of why we ventilate in the first place.

The session was chaired by BESA technical director Tim Rook who pointed out that this whole area was increasingly important to the UK because of rising pollution levels and the fact that our government has been sued twice – “ and lost both times” – for failing to put adequate air quality measures in place.

The webinar was attended by more than 50 online delegates dialing in from over 30 countries as well as the BESA Indoor Air Quality Group in London. View the slides and listen to the presentation and subsequent Q&A session here.
