Passivhus er gammelt nytt. Nå er det null energibruk som gjelder. Artikkel skrevet av Joachim Seehusen.

The main aim of this article is to rephrase good and bad performance of built environments as good or bad interplay of spaces, building technologies, and users. To support this perspective, two conceptual tools broadly used within the social study of technology are introduced. These concepts, the semiotic pair “script/antiprogram” and the study of “domestication of media and technology in everyday life,” were originally developed in the search for a better understanding of the mutual shaping of culture/society and technology. In this contribution, these concepts are applied in an empirical study of two nonresidential buildings. Through an extension of these…

Vacuum insulation panels (VIPs) are regarded as one of the most promising existing high performance thermal insulation solutions on the market today as their thermal performance typically range 5–10 times better than traditional insulation materials. However, the VIPs have several disadvantages such as risk of puncturing by penetration of nails and that they cannot be cut or fitted at the construction site. Furthermore, thermal bridging due to the panel envelope and load-bearing elements may have a large effect on the overall thermal performance. Finally, degradation of thermal performance due to moisture and air diffusion through the panel envelope is also…

How can researchers and planners best facilitate the transition to low-carbon societies? In particular, can they initiate better dialogue in order to foster stakeholder engagement in planning, building and living in low-carbon settlements? These challenges inform a municipal planning process for a new neighbourhood in Trondheim, Norway: Brøset, as well as for an interdisciplinary research project exploring the role of action research in supporting the transition to low-carbon societies. The processes are described for identifying the central actors and applying the dialogue strategies in the early planning project phase. Researchers and planners collaborated to contribute to new knowledge production and…

In this work, the thermal performance of three different wall configurations was examined by hot box measurements and numerical simulations. Vacuum insulation panels were sandwiched between traditional insulation in walls where the load-bearing elements were standard 36-mm-thick wooden studs, I-profiled studs and U-profiled studs. The measured mean values of the thermal transmittance (U-value) were 0.09 W/m2·K with 36-mm-thick wooden studs, 0.10 W/m2·K with U-profiled studs and 0.11 W/m2·K with I-profiled studs. The comparison of the three wall structures has shown that with such low U-values, the numerical simulations are more sensitive to the accuracy of the dimensions and thermal conductivities…

The current state and future challenges of energy and buildings research are explored from the perspective of the social study of science. Major trends in knowledge production are considered for practices within current energy and buildings research. New forms of knowledge production hold the potential to provide clearer strategies to overcome barriers between researchers and practitioners. These are investigated through an explorative survey of researchers based on their own accounts of energy and buildings research, their expectations of future challenges, and their perceptions of ‘good’ science. Two sets of challenges from knowledge production arise for building energy research. First, with…
