Refurbishing residential buildings step by step with an individual refurbishment roadmap (iSFP)
Since July 2017, the new energy consulting tool – the “Individual Refurbishment Roadmap” (= individueller Sanierungsfahrplan, iSFP) – has been available nationwide in Germany. The iSFP was developed by experts from the German Energy Agency (dena), the Institute for Energy and Environmental Research Heidelberg GmbH (ifeu) and the Passive House Institute Darmstadt and has proved its worth in practice in Germany. The offer is very well received by energy consultants, planners, and homeowners, especially since it enables financially weaker households or hesitant owners to strategically tackle the complete refurbishment of their homes and buildings.
