Research Group 55 - Multi-storey social housing: Cost-effective and energy efficient – (not) mutually exclusive?
Social multi-story housing: Cost-effective and energy-efficient – a contradiction in terms?]]|||There is a great need for affordable housing, especially in metropolitan areas. It is to be expected that in the coming years, more residential buildings will have to be built at socially acceptable rents. The 55th Research Group on Cost-Effective Passive Houses shows, firstly, how the two objectives of “cost-effectiveness” and “energy efficiency” can be combined and, secondly, that buildings constructed to the passive house standard represent a proven solution for this. The model of 5-euro housing (warm rent per m²) from the housing company Neue Heimat Tirol is also presented (and critically examined). A series of examples shows which technical solutions can be used to achieve the EnerPHit standard cost-effectively, even in existing buildings. It becomes clear that it is not the efficiency standard of the building that drives up costs, but rather the requirements regarding fittings, parking spaces, basements, “good location” conditions, accessibility, fire protection, and so on. —- If climate protection goals are to be achieved, residential construction must play an appropriate role, and Research Group 55 shows that this is possible: with passive houses and EnerPHit, proven and economical solutions are available. Here is a brief summary of the key findings on cost-effective social housing construction.
