Pär Johansson
Associate Professor at
Chalmers, Architecture and Civil Engineering, Building Technology
Pär Johansson is Associate Professor at the Division of Building Technology, research team Building Physics Modelling. Pär works with high performance thermal insulation (superinsulation) materials, materials for thermal storage (heat and cold) and solutions for green and blue roofs. The aim of the research is to reduce the energy use in the existing building stock while minimizing risks when new materials are used in combination with old building techniques.Pär is coordinator for the Swedish Universities of the Built Environment (SBU) as well as leading a work package on thermal energy storage solution in Chalmers Energy Area of Advance, profile area Energy in Urban Development. He is also the Swedish representative in the board of AIVC, Air infiltration and Ventilation Centre and participates in CIB W040 and W080.
