Investigate the influence of daylight on the luminance distribution in an office and the appreciation of this luminance distribution by people. Develop and test procedures for dynamic control systems in an integrated daylight/artificial light environment.
The following work will be carried out:
Investigation of daylight parameters (literature study).
Review of existing lighting control systems.
Extension of existing models to model the combined luminous distribution produced by natural and artificial lighting under various control strategies; use of these models for office buildings (University of Strathclyde).
Investigate the appreciation of luminance by people in an operational test-office building. This work includes: establishment of a list of requirements, questioning of persons working in the office under different conditions, measure the actual lighting values and calculation of energy consumption with different control strategies. The impact of extreme daylight conditions will also be evaluated.
