Fremtidens energieffektive hus
Publication Year: 2012


Passivhusekspert Tor Helge Dokka har mange tanker om fremtidens bygg. Han spår fjernvarmens død, men tror fortsatt på varmepumpen. Intervju med Tor Helge Dokka i Teknisk Ukeblad. Artikkel skrevet av Fredrik Drevon.

Energy-plus, zero energy and zero emission buildings denote some of the best buildings of today and the future with respect to energy efficiency and environmental impact. A zero emission building might be defined in different ways. Nevertheless, the main concept is that renewable energy sources produced or transformed at the building site have to compensate for CO2 emissions from operation of the building and for production, transport and demolition of all the building materials and components during the life cycle of the building. In order to fulfill this, CO2 emission data has to be made available and verified for traditional…

For første gang lærer arkitektstudenter å tegne hus som produserer energi. Artikkel i Teknisk Ukeblad, skrevet av Joachim Seehusen.

This article proposes a new area of research centered on the study of how energy sensibilities—in terms of esthesia which is understood as responsiveness and awareness—are distributed and redistributed. Energy is approached as a polyphonic concept with many meanings, of which none enjoys privileged status. Given this polyphony, the common observation that end-users have no idea (or wrong ideas) about their energy consumption loses importance. Instead, unevenly distributed ways of sensing and making sense of energy become the object of study. Drawing on the work of French philosopher Jacques Rancière, the article discusses contemporary distributions of energy sensibilities in domestic…

A case study of a Norwegian detached house is used to evaluate the sustainability of two nearly zero energy renovation strategies. Energy demand, life cycle cost and home qualities are assessed as sustainability indicators. The Façade renovation strategy is an energy upgrade of the façade supplemented with high renewable energy production on site. The Ambitious renovation strategy is a total building envelope upgrade using passive house components and a lower on site renewable energy production. Both renovation strategies result in a 50–85% reduction of the heating requirement depending on the renewable energy production. The sustainability assessment was done as an…

Ådland får verdens mest miljøvennlige boliger, mener Arbeiderpartiets Ruth Grung. Tirsdag ga miljøvernministeren grønt lys for nullutslippboligene på Ådland.   Skrevet at Terje Bringsvor Nilsen

Building integrated photovoltaics (BIPVs) are photovoltaic materials that replace conventional building materials in parts of the building envelopes, such as roofs or facades, i.e. the BIPV system serves dual purposes, as both a building envelope material and a power generator. Hence, it is important to focus on the building envelope properties of a BIPV system in addition to energy generation performance when conducting experimental investigations of BIPVs. The aim of this work was to illustrate challenges linked to the building envelope properties of a BIPV system, and to develop and evaluate relevant methods for testing the building envelope properties of…

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…

The optical characteristics of an advanced glazing system are presented in this paper. The investigated glazing system is based on the incorporation of a paraffin-based Phase Change Material (PCM) into a transparent component, made of two extra-clear glass panes and a cavity where the PCM layer is placed. Due to the highly scattering property of the system (when the PCM is in solid state), the use of a large integrating sphere equipment (75 cm diameter) is necessary to obtain reliable results. The spectral transmission, reflection and absorption coefficients of the PCM glazing system are measured between 400 and 2000 nanometers,…
