Pär Johansson
Forskarassistent at
Chalmers, Architecture and Civil Engineering, Building Technology
Pär Johansson is since June 2015 assistant 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 his 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.Vacuum insulation panels (VIP), aerogel based products (ABP) and phase change materials (PCM) are investigated and tested in field and laboratory. Risks when new materials are used in combination with old building techniques are identified by building characterization, measurements and modelling of temperature, relative humidity, indoor moisture production, and thermal properties of insulation materials and PCMs.Pär is leading a work package on thermal energy storage solution in Chalmers Energy Area of Advance, profile area energy in urban development and participates in the national transdisciplinary centre of excellence SIRen.
