The Danish Daylighting Programme Esbensen Consulting Engineers, Denmark Erwin Petersen Danish Technological Institute, Denmark Søren Aggerholm Kjeld Johnsen Jens Christoffersen Danish Building Research Institute, Denmark Summary The Danish daylighting research programme is funded by the Danish Energy Agency, and the programme runs through 1991 - 1995. This programme is jointly undertaken by Esbensen Consulting Engineers, the Danish Building Research Institute and the Danish Technological Institute. The main objectives of the programme is to investigate and document daylighting techniques to be used in non-domestic buildings. The techniques are sidelighting techniques such as reflective blinds and louvers, and reflective light shelves. The systems are being tested in a new daylighting testing laboratory which has been built at the Danish Technological Institute. In this laboratory, control systems for artificial lighting are also being tested. Improved use of daylighting in existing buildings is also being investigated. This is done through case studies on buildings, where alternatives for renovation of window systems, shading systems and lighting systems are being evaluated. The use of daylighting is seen as an integrated part of the overall energy strategy of the building. The energy consumption for heating, cooling, ventilation and lighting is modelled using the tsbi 3 computer model, and using the ADELINE programme package for daylighiting modelling. Recently a new pan-European daylighting research programme has been proposed for the EC JOULE II programme. This programme is proposed by Poul E. Kristensen, Esbensen together with a group of energy and daylighting specialists throughout Europe. The main objectives of this project is to monitor the daylighting performance of 17 selected buildings throughout Europe and to document the results in high quality case studies. The objective is further to analyze the various daylighting techniques for non-domestic buildings. These results will be documented in "Daylighting Design Guidelines for European Buildings", the main deliverable of the project.
