KMO Reno (P0187290AX0)

Starting in the 1970s, massive SME buildings were constructed using new, fast construction methods (system construction). Meanwhile, these box-shaped buildings are outdated and the building envelope no longer meets today's requirements in terms of energy performance, comfort and aesthetics. Renovation of these buildings therefore represents a new business opportunity. The current lack of theoretical and practical knowledge about renovation options for these types of buildings, tailored to construction companies, leads to suboptimal implementation practices. This involves both building-technical questions, such as the structural load-bearing capacity and integrity of the current condition, as well as more building-physical and practical aspects such as risks of (internal) condensation, guaranteeing airtightness and detailing that is feasible in practice. KMO Reno focuses on the qualitative renovation of SME buildings. Starting in the 1970s, these were built using new, fast construction methods (system construction). Meanwhile, these box-shaped buildings are outdated and the building shell no longer meets current requirements in terms of energy performance, comfort and aesthetics. Renovation of these buildings therefore represents a new business opportunity. The current lack of theoretical and practical knowledge about renovation options for these types of buildings, tailored for construction companies, leads to suboptimal implementation practices.

Results:KMO Reno supports the industry, by developing a renovation guide specific to the building shell. The building professional can use it from the first building visit to the completion of the work. Among other things, this renovation guide includes a quick-to-implement screening protocol that allows critical points to be analyzed, a compatibility matrix that indicates, based on the construction method of roof and/or façade, which renovation methods are possible and what any limitations are, execution guidelines with guidelines for quality execution of both wall construction and building nodes/construction details. In addition, 10 case studies are conducted and documented. The technical solutions are tested in a test-box for air tightness, placability, water tightness, ... This provides concrete useful information for building professionals. In the first year, a theoretical overview of possible technical solutions for the renovation of the building shell was made. Based on this, a test program was established. The results were published on the website, and in professionally oriented journals.
