Absolute sustainable CO2-limits for buildings should reflect their function. A case study of four building typologies

Absolute sustainability gains increasing attention in the building industry. climate limits is often expressed kg CO2-eq/m2/yr. This type of threshold has one main problem; it specified per area, which rewards larger buildings regardless need that they fulfill. way setting may thus lead to increased future impacts from buildings. The purpose this study developing principles for differentiated CO2-limits buildings, reflect importance function delivers its users. We use Fulfillment Human Needs sharing principle on a sufficientarian ethical norm. method was demonstrated four buildings; residential, university, hospital and kindergarten, guidance given how apply any typology. should be seen as demonstration concept determining different typologies.
