It is becoming conventional approach to evaluate the building envelop losses using detailed dynamic tools such as EnergyPlus, ESP-r and TRNSYS. However, the user-related loads (and their variations) in the building are usually oversimplified during performance evaluation of those buildings and associated HV AC systems. This paper presents a methodology to evaluate the performance of buildings and their energy supply systems while taking into account the user-related loads (non-HV AC & DHW) at individual household levels. For this purpose, a single family house (two different insulation cases) built in Oslo climate using an alternate duty air to water heat pump…

State-of-the-art wood stoves could be an attractive solution for the space heating of passive houses. The question of the integration of wood stoves in passive envelopes is rather new and still open, the main constraints being the power oversizing ant the heat distribution. The paper proposes a low-resolution simulation approach to provide an insight into the whole-year thermal comfort using a stove, and into the relative effect of the large number of physical parameters involved in the problem. In particular, a simple stove model is developed for detailed dynamic simulations in order to fairly represent the heat emission properties of…

Responsive Building Elements (RBEs) and energy storage within the building are considered as a crucial development towards the nearly Zero Energy/Emission Building target. The exploitation at the building scale of renewable energy sources and the opportunities offered by the environment is achieved by the ability of the RBEs to dynamically adapt to changing environmental conditions. Among these concepts, Advanced Integrated Façades (AIFs) are probably one the most promising technologies, due to the important role that the building envelope plays in controlling the energy and mass flows between the building and the outdoor environment. In the framework of a decade-long research…

While window frames typically represent 20%"30% of the overall window area, their impact on the total window heat transfer  rates may be much larger. This effect is even greater in low-conductance (highly insulating) windows that incorporate very low  conductance glazings. Developing low-conductance window frames requires accurate simulation tools for product research and  development.  The Passivhaus Institute in Germany states that windows (glazing and frames, combined) should have U-factors not exceeding  0.80 W/(m² K). This has created a niche market for highly insulating frames, with frame U-factors typically around 0.7-1.0 W/  (m² K). The U-factors reported are often based on numerical…
