standardisation

The rapid growth in the use of low-cost sensors for indoor air quality (IAQ) measurement campaigns, following the COVID-19 pandemic, has significantly improved public awareness of ventilation and IAQ in buildings. Yet, we still know very little about the level of pollutants in our indoor environments. Unlike outdoor air, IAQ is not routinely actively monitored and there are currently no widely accepted, standardised methodologies, procedures or regulations for doing so.  

In 2004 the first adaptive thermal comfort guideline was introduced in the Netherlands. Recently a new, upgraded version of this ISSO 74 (ATG) guideline has been developed. The new requirements are hybrid in nature as the 2014 version of the guideline combines elements of traditional non-adaptive comfort standards with elements of adaptive standards. This paper describes the new guideline and explains the rationale behind it. Also changes in comparison with the original 2004 version and issues related to performance verification are discussed.
