Residential care center ‘Zusters Annuntiaten’ Heverlee, BE Studiebureau Boydens

description

This senior residential and care center encompasses renovation of the existing structure and an extension.

The energy concept is the simple but a revolutionary principle in which the renewable heat pump technology is combined with a conventional condensing gas boiler installation, in order to cover the heat demand. This in combination with 8 gas fireplaces, can be found in the central living room, which is a clear illustration of the integration of architecture and engineering. Furthermore, the distribution of heat occurs in the building using a combination of floor heating and concrete core activation in combination radiators at a low temperature regime.

The trias energetic model was applied within the predetermined economic framework. The building envelope was optimized and technological renewable sources were applied for the completion of the demand for energy. Specifically, in this case a borehole thermal energy storage (BTES) field is executed, consisting of 85 holes with a depth of each 100 m. Whereby during the winter months this heat source is utilized with the aid of a heat pump, and during the summer provide the necessary cooling to achieve the desired comfort. This system is further supported with the use of a high efficiency gas fired condensing boiler installation. The entire ventilation concept including the service flats utilize the D-type ventilation system with a maximum efficiency of heat recovery.

Domestic hot water is preheated by solar hot collectors on the roof.
