Samenvatting

Sustaining historical buildings does not always align with the ambition to promote sustainability in the built environment. In this paper we explore the dynamics and strategies that spring from this basic tension, by investigating the differences and similarities between expert’s valuation and peoples’ valuation of historical buildings, as well as their views on energy efficiency. Our paper highlights mediaeval churches in Groningen, which represent an important European heritage. We cooperate closely with the SOGK, a regional organization that is taking up the challenge of maintaining these churches in a region that is depopulating, secularizing and, to all that, suffering from earthquakes.
