PASSIVE SOLAR ENERGY IN AN INNOVATIVE OFFICE BUILDING

Objectif

The aim of the project is to demonstrate the possibilities of a substantial reduction in the energy use of a commercial building in a region of the Community, where there is a large potential for such ideas.
The aim is to reduce both the heating load and especially the electricity load for lighting, ventilation and cooling: this is done using natural design strategies: An integrated atrium, use of daylight, reduction of ventilation load and cooling load via efficient solar control in the windows, control of artificial lighting, and use of evaporative cooling.
The main part of the remaining heat load and electricity load is covered by a local small-scale combined heat and power plant.

TECHNICAL DESCRIPTION
ATRIUM : The integrated atrium and the building around it is optimized, so that auxiliary energy use of the building as well as electricty load for artificial lighting is reduced. The atrium is an intermediate temperature zone, allowing larger windows areas towards the atrium, thereby improving the daylight penetration into the office spaces towards the atrium.
INTEGRATED SOLAR CONTROL WINDOWS : The exterior window have sealed glazing units which movable solar and daylight control blinds. These windows allow ample daylight in during overcast days. On sunny days direct sunlight is controlled and reflected onto the ceiling to improve daylight penetration into the building, and avoiding discomfort due to direct radiation.
EFFICIENT LIGHTING SYSTEM : In order to fully exploit the possibilities of reducing electricity consumption for artificial lighting via use of natural daylight, a high efficiency lighting system with daylight responsive control is installed.
PASSIVE EVAPORATIVE COOLING : The cooling load is reduced due to the efficient shading devices in the windows. The remaining cooling load is covered via passive evaporative cooling through the high efficiency heat recuperation system. When there is a cooling load, the exhaust air is evaporated and thereby cooled down before passing the heat recuperator.
LOCAL HEAT AND POWER GENERATION : A small scale combined heat and power plant is situated in the building. The fuel is natural gas. The plant consists of three modules and a diurnal thermal storage system. This system design allows maximum flexibility on daily and seasonal basis, so that electricity is produced at the rate required by the building, and heating can be consumed when required.
IMPLEMENTATION
The project is carried through in a team consisting of Schlote Architekbuereau in Berlin, Esbensen Consulting Engineers in Copenhagen, and Industriebau Fuerstenwalde in Fuerstenwalde (East) Germany.
The project will run through thephases of preliminary design (design optimization) start in June 1992, detailed design, construction (March 1993 - July 1994) and monitoring and evaluation.
