Building Performance Aspects

How about fire safety? Privacy? Air pressure? Noise resistance? Protection from solar radiation? Electrical safety? The list of performance aspects that are important in the context of building and construction is long. Below are some visuals to make the point.

Buildings have to do a lot of things. These things buildings do are typically named building functions; building performance then measures how well the building carries out that function. As functions typically are defined as doing something (provide thermal comfort, maintain occupant safety, etc) their formulation requires a verb. Performance aspects are the categories that require attention, without the verb. There is no final overview of performance aspects, and it is important to keep in mind that most buildings have their own specific reason for being and corrsponding performance aspects. The list below is a collection of performance aspects gathered over the years; verbs that help to turn the aspect into a building functions are addded in brackets. Suggestions for new additions are always welcome.
