At the beginning of the year, the Interregional Hospital Center Edith Cavell (CHIREC) opened its brand new hospital at the Delta site in Brussels. More than 100,000 square meters in size and built with a particular attention for energy and sustainability. In addition to geothermal and solar energy, an efficient combined heat and power plant will help the hospital to produce as much energy as possible and to minimize the impact on the climate.
The CHP unit with an electrical capacity of 600 kWe is housed in a separate powerhouse and accounts for 20 to 30 percent of the hospital's electricity demand. Vanparijs Engineers, subsidiary of EDF Luminus, designed and built the entire installation, including all peripherals such as the acoustic enclosure, piping, exhaust system, cooling circuits, gas detection and oil storage. In addition to the recovery of the high and low temperature heat, the heat from the flue gases can also be recovered thanks to a flue gas condenser on the exhaust. The generated heat is used integrally for the central heating of the hospital. In warmer periods the excess heat can be stored in a buffer tank for later use.
The entire installation is monitored from a distance and maintained by the Vanparijs Engineers service team. Thanks to a 24/7 service and a performance contract with guaranteed availability and efficiency, the hospital receives the necessary guarantees for the proper functioning of its installation during at least ten years.
The energy installations of the hospital are also linked to the adjacent project site. The heat CHIREC does not need is supplied from the powerhouse to the buildings of Delta Ouest. This smart district heating network makes the energy generation even more sustainable and ensures an economic win-win for the hospital and neighbourhood.
