Abstract:
The work develops an integrated assessment system for the comparative evaluation of high-tech and low-tech buildings in terms of their contribution to overcoming societal challenges. While high-tech buildings focus on efficiency and intelligent technical systems, low-tech buildings focus on sufficiency and passive measures. Previous assessment systems (SRI, LowTRI, DGNB) do not treat both approaches equally. The system is based on a utility analysis and combines the three dimensions of sustainability (ecology, social, economy) with nine key challenges and three strategies (efficiency, sufficiency, consistency) in a matrix structure. With over 23 differentiated indicators, it enables the systematic recording of both mechanisms of action and their aggregation into an overall index. The central finding of the work is that comparability does not fail due to fundamental incompatibility, but rather due to a lack of integration of different evaluation logics. The system closes this gap and, for the first time, offers a sound basis for decision-making for the objective evaluation of both building concepts on a common basis.
