nZEB Renovation with Prefabricated Modular Panels

Abstract The reduction of energy use in buildings is expected to be reached in part by fulfilling several requirements of the low- and nearly-zero energy buildings (nZEB) policy. The improvement of energy performance of buildings offers a huge potential for energy savings as the annual replacement of existing stock is only 1–2%. The efficient way to accomplish the purpose of the nZEB is to apply the integrated design process and application of prefabricated modular renovation elements on a large scale. In the Horizon2020 MORE-CONNECT project we developed prefabricated modular elements for the building envelope insulation and with the use of these elements, the nZEB renovation will be realized as a pilot. The study includes a complex of measures: hygrothermal measurements and analysis of moisture safety, prefabricated highly-insulated facade and roof modular renovation elements, full repair of indoor areas, rebuilding of balconies, insulation of cellar constructions, the full modernization of heating and ventilation systems. Ventilation ducts are integrated into the modular panels to minimize supply ductworks in apartments. Roof modules include solar panels and collectors for renewable energy production as well as a system for rainwater drainage. All technical systems and building modules will be equipped with monitoring systems and data will be logged periodically.
