Energy consumption of buildings significantly depends on indoor environment requirements, building design and operation and systems. Indoor Environmental Quality (IEQ) includes thermal, indoor air, light and acoustics aspects of the indoor environment. IEQ affects health and productivity of the occupants and hence its evaluation is crucial for the occupant’s behaviour in relation to building spaces and systems (e.g., use and control of windows, shadings, HVAC, lighting, etc.). Recent studies have also demonstrated that costs of the deteriorated indoor environment for the society, employer and building owner are significant. At the same time, latterly the COVID-19 pandemic has driven a complete rethinking of strategies for the management of indoor air quality, indoor environmental quality and also the ergonomics of indoor environments.
A correct assessment of building energy performance has to properly take into account IEQ aspects; to this purpose, several international standards and guidelines have been introduced with the aim to provide criteria for thermal comfort, air quality, acoustic and visual comfort.
This course provides design criteria for IEQ of different types of buildings, methodologies for performing in-field measurements and subjective surveys. Eventually the course is aimed at discussing the most important factors related to IEQ influencing the building energy performance at both the design and operational stages.
