Abstract


Μany believe that mechanical ventilation with heat recovery (MVHR) is a necessity in dwellings with increased standards of thermal insulation and airtightness, such as plus-energy houses. However, there is evidence that controlled natural ventilation can provide comfortable indoor conditions without increasing energy consumption in temperate climates. The aim of this project is to design and test a control strategy for natural ventilation in plus-energy houses that can operate effectively in temperate climates. The energy-plus house “Home+” that was designed and constructed by the Faculty of Architecture and Design at the University of Applied Sciences in Stuttgart and won the third place in the first edition of Solar Decathlon Europe was used as a case study. Both Dynamic Thermal Modelling (DTM) and Computational Fluid Dynamics (CFD) were used in order to predict energy consumption and assess the indoor air quality and thermal comfort of the occupants.
