Short description: How to improve the energy efficiency of buildings located in the historical zone? After all, there are rules that limit the possibilities of insulation. And so it is necessary to find fundamentally new solutions to improve energy efficiency in historic buildings.
Market potential: Potential beneficiaries of this new energy efficiency solution for historically valuable buildings could be countries/cities where such buildings exist.
Timing: This problem must be resolved as soon as possible.
Desired result: Solutions must be found for inexpensive methods of improving the energy efficiency of buildings built in the 1950s and 1960s and located in the historical area of the city of Kohtla-Järve.
Information on challenge owner: City/municipality.
Keywords: Energy Efficiency; Energy House; Residential Building; Historic Building
