Reflections on the Evidentiary Basis of Indoor Air Quality Standards

Buildings are expected to provide healthy and comfortable indoor environmental conditions for their users. Such have diverse dimensions, including thermal, visual, air quality, auditory, olfactory aspects. Indoor quality standards, guidelines, codes typically inform professionals in the building design operation phase view of procedural, contractual, legal boundary conditions. Given this critical role it seems significant examine applicability scientific validity on a regular basis. In context, present paper focuses standard-based definition (IAQ) indicators respective values. Hence, main aim effort is study several common national international IAQ standards scope which they include direct or indirect evidence mandates requirements. To end, selected were assessed via structured schema that includes not only basic information, indicators, suggested recommended value ranges, but also any reference studies. The findings identify certain issues with transparency chain from results technical literature recommendations. Moreover, recommendations made development future transparent evidence-based guidelines.
