27 International Passive House Conference lecture | Speaker: Michael Kölmel

Building renovations are necessary but often challenging. However, if energy-efficient renovations are carried out at the same time, the rewards are high: significant energy savings, low energy costs and a high level of living comfort. Nevertheless, the effort involved remains a hurdle: apart from investment costs, there is dirt, noise, restrictions and uninhabitability during a lengthy period of work. This is where serial renovations come in: extensive, standardised prefabrication. Depending on the initial situation, even including a building envelope, is intended to simplify renovations, significantly reduce time spent on site, and of course save a lot of energy. However, quality often falls by the wayside.

ZELLER KÖLMEL Architects demonstrates how serial renovation can be successfully combined with highly energy-efficient measures to create sustainable buildings and neighbourhoods in their projects. This additional service of 'convenient' implementation and a pleasant construction site for all involved does not come for free. With appropriate funding, the concept is being implemented in social housing construction.
