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…

Sammendrag Denne rapporten beskriver resultatene fra et prosjekt hvor vi har gjennomgått og diskutert erfaringer fra et utvalg utbyggingsprosjekter i Norge hvor man har hatt spesielt høye ambisjoner med hensyn tilenergibruk og klimagassutslipp. Prosjektets målsetning er å bidra til økt kunnskap om gode løsninger for utforming av bygninger og energiforsyning for fremtidens boligområder, samt danne underlag for enveileder til bruk i planleggingsprosessen. Hovedkonklusjonen er at det er behov for mer kunnskap og veiledningsmateriale om hvordan man kan integrere dette tidlig i planprosessen. Følgende punkter erspesielt viktige:  Fokus på integrert, tverrfaglig prosjektering fra tidligfase. Formulering av konkrete krav/målsetninger i tidligfase. Undersøkelse av tilgjengelighet og…


Reliable methods are needed for classifying the robustness of buildings and building materials for many reasons, including ensuring that constructions can withstand the climate conditions resulting from global warming, which might be more severe than was assumed in an existing building’s design. Evaluating the robustness of buildings is also important for reducing process-induced building defects. We describe and demonstrate a flexible framework for classifying the robustness of building materials, building assemblies, and whole buildings that incorporates climate and service life considerations.

ABSTRACT The path toward energy-efficient buildings with a low or zero carbon footprint, e.g. zero energy and zero emission buildings, involves the development of high-performance thermal insulation, aiming at reaching thermal conductivities far below 20 mW/(mK). Applying such superinsulation will allow the construction of relatively thin building envelopes yet maintaining a high thermal resistance, thus also increasing the architectural design possibilities. A vacuum insulation panel (VIP) represents a stateof-the-art thermal insulation solution with a thermal conductivity of typical 4 mW/(mK) in the pristine and non-aged condition. However, the VIPs have issues with fragility, perforation vulnerability, increasing thermal conductivity during time…

Improving energy efficiency in dwellings is generally seen as the low-hanging fruit of climate change mitigation. In particular decreased heat loss through better insulation is suggested as one of the most cost-effective means to achieve the ambitious national and international goals of climate gas reduction. However, the literature shows that a profitable technological solution is not sufficient to reach the energy goals. Aspects such as a lack of information, unobserved costs, and heterogeneity among users can compromise the success of technical innovation. Still, there are successful concepts that drive the technological development in the construction sector. The Passive House is…

We are currently witnessing in the Norwegian building sector (and elsewhere) the transition from isolated and heterogeneous sustainable building projects carried out in protected niches (e.g pilot projects) to more sustainable buildings becoming mainstream. According to scholars studying sustainable transitions this is the moment in which a dominant design catches on, replacing and displacing other more or less sustainable alternatives. Within this process, in the Norwegian case, the principles behind the passive house play a salient role. In fact, only recently a government white paper has called for "passive house levels" to become part of the building code by 2015.…

The role of tunnel K+ ions on the growth and stability of tunnel-structured cryptomelane-type MnO2 nanofibers (denoted as cryptomelane nanofibers hereafter) has been discussed by means of X-ray diffraction and electron microscopy. Cryptomelane nanofibers with typical diameters of 20–80 nm and lengths of 1–6 μm have been synthesized by means of a simple hydrothermal reaction of KMnO4 and MnSO4 aqueous solutions at 140 °C. The growth of cryptomelane nanofibers under hydrothermal conditions follows a dissolution–recrystallization process and involves a morphological transformation from a layered precursor to the tunnel-structured cryptomelane, in which the K+ ions play important roles in templating and…

Within the frame of this exploratory essay, small studies in materiality are introduced as artifacts of relatively simple means, designer driven, and as useful in anchoring strategies to reflexively map research methods in art and design practices. Using concepts from science and technology studies (STS), a series of projects are contextually presented and modes of working are tracked. Small studies discusses how artists and designers can better position themselves to critically assess relationships between the complex, interconnected design issues they encounter in their artistic practices, and the methods they opt to employ. The essay concludes that in fields where art…
