Optimal renovation strategies

The general objective of this part of the One Stop Shop project was to have elaborated case studies that give the building owners (and contractors) insight in the costs and environmental impact of several whole building renovation strategies. More specifically the objectives were:

  • To document and demonstrate the costs and benefits of deep retrofitting in terms of financial and environmental impact for investors in real case studies. The executed case studies are documented in terms of initial investment and (energy) costs over a longer period.
  • To explore the feasibility (and create a cost profile) of alternative renovation scenarios, with a main focus on the achievement of a ‘nearly zero energy standard’1. Analogously the environmental impact of different scenarios will be explored to investigate the relation between impacts resulting from additional material use versus impacts related to the (reduced) energy consumption.
  • To evaluate the robustness of the results obtained through identifying the most sensitive cost elements, risks and ranges of validity.

The output of this work was used further in the OSS work program: demonstrated costs/benefits for communication to and by SMEs; cost aspects and validity of results in relation to business concepts; information and dissemination to technical and general audience.
