Abstract

Abstract: The development of a new tool (IEQ Compass) for holistic evaluation of indoor environmental quality (IEQ) is presented. The purpose of the new tool is to facilitate a broader understanding of IEQ, its importance for comfort, health and well-being, and to help and guide the building design process regarding IEQ. The tool evaluates the potential indoor air quality (IAQ), thermal, visual and acoustic IEQ, without considering user influence. The evaluation uses 16 parameters, four for each of the four areas of IEQ (IAQ, thermal, visual and acoustic IEQ). These are evaluated based on relevant criteria assessed from blueprints, existing building information modelling data or observations during building inspection. The criteria and parameters are weighted to obtain an overall IEQ label for the building, as well as partial labels for the four areas. The labelling scheme uses letter ranking and colour code similar to that used in energy performance certification. The results are also communicated through the newly developed "IEQ Design Compass ", which is a detailed graphical visualisation at criteria level and helps identify potential IEQ problems that warrant attention. Highlights: The tool "IEQ Compass" was developed to evaluate the potential indoor environmental quality (IEQ). It evaluates four areas, indoor air quality (IAQ), thermal, visual and acoustic IEQ. It provides an overall "IEQ label" using a letter and a colour code similar to energy labels for buildings. The four areas (IAQ, thermal, visual and acoustic IEQ) are also labelled individually. The "IEQ Design Compass" visualises the results in detail and provides an overview that aids indoor environmental design.
