This paper addresses a range of parameters that are vital for buildings and their inhabitants in respect to indoor air quality (IAQ), thermal comfort and daylight requirements in Belgium–Brussels Region, Denmark, France, Germany, Italy, Poland, Sweden and the United Kingdom – England and Wales. The results of the analysis shows that all studied Member States (MS) have at least a basic reference to IAQ included in their building codes. In all 8 MS, minimum ventilation rates are required or recommended while precise airtightness requirements are in place for 6 MS (Belgium, Denmark, France, Sweden, Poland, and United Kingdom). In respect to thermal comfort indicators, indoor temperature requirements or recommendations vary between 16 °C -in Poland- and 28 °C -in France- while recommendations about humidity are given in 6 MS (Germany, Poland, Italy, Sweden and United Kingdom). Furthermore, all MS studied include at least a basic reference to daylight in their building codes mainly referring to a minimum share of window area per floor area and minimum levels of daylight. The authors conclude that indoor health and comfort aspects should be considered to a greater extent in the EU and national building codes.
