ABSTRACT
The 1800 m2 Focus 21 building is built during 1994, and will become one of the most important exhibition buildings in Denmark, with respect to showing new energy strategies for office buildings integrated in an outstanding architectural design. Especially daylighting techniques, the demonstration of architectural use of PV-elements and the use of various optimization methods has been the main topics in the energy design of the building. The paper describes the methods and the results of the work carried out by an international design team during 1993. The energy consumption for heating and ventilation of the building has been simulated with the tsbi3 thermal simulation programme and daylight availability and savings on electricity for lighting has been simulated with Adeline/Radiance, an integrated daylighting design tool. The simulations show a total annual energy saving of about 60% of the normal energy consumption in office buildings in Denmark. Hereby the building will comply with the long term energy saving targets of the Danish national energy plan: Energy 2000.
The project has been supported by EU Joule II “The Solar House” research programme, and will go through very comprehensive monitoring and dissemination phases, adressing decision makers, consultants and architects throughout Europe.
