The comfort and energy demand of a building are influenced significantly by glazed area of the facade. The glazed areas in the building are always challenging. Large glazing allows more daylight to get into the room but at the same time cause more heat gain and heat loss through the building envelop. Shading devices are very suitable elements for installing PV panels. The aim of this study is to evaluate the potential impact of different PV shading devices on energy performance and daylight of office buildings in Nordic climate.

Buildings are responsible for 38 % of energy use in Norway, about 64 % of which is heating energy. Lacking of architectural design at the early design stage has adverse consequences on the climate and environmental efficiency of buildings, which is a burden for reducing the energy consumption of buildings. This research uses Ådland project as a case study in order to investigate how the building morphology which is one aspect of the architectural quality will impact the heating demand of buildings. The research is based on the design which is ongoing in the Research Centre of Zero Emission Buildings…

The main direction of the thesis is analyzing the impact on solar access and energy demand of different building mass in linear building forms. The study model of this work is a current ongoing project - a suburb sustainable residential community design project locates in Ådland, Bergen, Norway. The work mainly consists of two parts: theory and project analyses. Both two parts are focusing on reducing environmental impact of suburb sustainable residential communities. More specifically, the theory is aiming on finding out the critical design and energy issues for suburb sustainable residential communities. The project is aiming on using the…

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…
