Research on indoor air quality for homeworkers
Millions of people now work from home because of Covid-19 restrictions, but are they working in a healthy environment? Researchers have assessed the impact on indoor air quality in eight homes. Anastasia Mylona reports
Air of authority: interview with Professor Catherine Noakes
Professor Catherine Noakes’ knowledge of ventilation and infection transmission has made her one of the government’s key scientific advisers on Covid-19. In recognition of her work, she was made an OBE last month. Alex Smith talks to her about the challenge of winter and the impact of infection control going mainstream
Winter protection: version 4 of CIBSE’s Covid-19 Ventilation Guide
The cold season brings new challenges for building managers trying to minimise the Covid-19 risk while maintaining occupant comfort. Chris Iddon introduces the latest CIBSE guidance on optimum HVAC strategies for Covid-secure buildings
Case study: retrofit of Fairfield Halls theatre
Fairfield Halls theatre in Croydon is a prime example of 1960s public architecture, so when Max Fordham was asked to devise a services strategy during a major refurbishment, it had to stay faithful to the original while maintaining 21st-century comfort and efficiency. Andy Pearson reports
Unwanted guests: bipolar ionisation in hotel rooms
Bipolar ionisation can improve air quality and remove odours from hotel rooms, says Spire Building Services’ Adam Taylor, who highlights research in Spain on its use to reduce the risk of Covid-19
Thinking outside of the box: the 2020 CIBSE ASHRAE Technical Symposium
Covid-19 may have moved the 10th CIBSE Technical Symposium from auditorium to desktop, but the expertise and knowledge shared by more than 70 speakers, made it an enriching experience for those who tuned in. Alex Smith, Liza Young and Phil Lattimore report
Understanding Hepa filters

Clear guidance: TR40 Best practice for exhaust ventilation
The risk of death and illness because of exposure to hazardous substances in the workplace can be cut by following the best practice guidance in ILEVE and BESA’s new TR40 publication. Alex Smith summarises the guidance aimed at the safe design and installation of local exhaust ventilation
Calculating Covid-19 risk according to activity and indoor space
A group of UK researchers has attempted to quantify the transmission risk of airborne Covid-19 infection according to activity and type of indoor space. Chris Iddon describes the methodology and how the risk of infection falls as ventilation rates are increased
