Task 21

Publications and Outcomes

Results for Building designers and industry

Through the Task several workshops have been organized with participation from practitioners and the Task participants. ADELINE workshops have been organized in Australia, Canada, Germany, and the Netherlands. Workshops on the use of the protocols described in Monitoring Daylight Performance in Real Buildings (including POEs) were arranged in Canada and Germany. The workshops have proven to be an effective way of communication from the Task to 'the market' and to get feedback during the research and development phase.
