“The handbook has explanations and signposts to a wide variety of IAQ style instruments suitable to the NCC indoor air quality verification methods,” suggests Vince Aherne, F.AIRAH, who led the revision of the manual. “References have been current and new applications included such as CO2 checking and air flow examination.”

Despite the fact that the techniques in the handbook do not involve unique requirements for biological contaminants – which would contain viruses and COVID-19 infectious aerosols – similar ideas are applicable when it will come to blocking the spread of airborne pathogens.

“Many of the regular IAQ equipment and approaches are suitable to microbial regulate,” says Aherne, “including, dilution, pressurisation, extraction, and air cleaning.”

The handbook has also been current to align with the new clause numbering and construction of NCC.

The Indoor Air High-quality Verification Methods handbook is offered from the source library at the ABCB website.
