EBES - Energy efficient residential building.

The new building and HVAC technology was used when an EBES multistorey residential building was built in Helsinki. In the EBES system the building structures are used as an installation space for the heating, piping, ventilation and electrical systems. Building structures are also used as a storage for heating and cooling energy. The main objectives of the overall EBES system are to improve the indoor air quality and energy economy and at the same time to improve the quality of the construction process and reduce costs. The ventilation system is a mechanical supply and exhaust air system having efficient heat recovery. It is supported by an intelligent programmable controlling system. The ventilation system is designed so that no adjusting and balancing is required after installation. In thr EBES system it is possible to use complex demand-controlled ventilation systems if desired. In this building manual control by residents was used. In each room the indoor temperature is individually controlled and the resident may choose the temperature level desired. All the HVAC components were tested in the laboratory before installation. All phases of the construction were monitored and filmed by video. The field monitoring of the indoor climate, energy consumption and operation of the system are presently in progress. The project will continue up to the end of 1992.
