Project Description:

The “House of Solidarity” has been completely renovated in order to optimize it energetically. It houses several modular landscape offices, flexible meeting rooms, an auditorium for 500 people, a refectory and a parking area with 80 places as well as technical rooms.
The following measures were taken:

• The façade is a combination of full façade sections and glazing which was chosen to limit heat loss but to maintain plenty of natural daylight.
• A high-performance airtightness to guarantee an efficient energy level (even if this is not imposed by the EPB legislation)
• The installation of external sun protection to limit overheating and the external factors during the summer and to maintain them to the maximum during the winter.
• Limiting the ventilation losses through the use of air handling units with a high efficiency heat exchanger.
• Use of condensing gas boilers of which the efficiency is maximized by heat production on a low temperature regime.
• Use of reversible radiation ceilings on a low temperature regime that function both in heating mode and cooling mode.
• Use of light-sensitive detectors, to maximize the use of natural light and minimize the use of (unnecessary) artificial light
• Use of automatic tap work to optimize the city water that needs to be used.
