Results of the cogeneration experience for the RTBF-Hainaut buildings in Mons

For its new building in Mons, the RTBF (Radio and Television organism of the Belgian French Community) decided, with the help of the Walloon Region, to design several equipments with special techniques characterised by a rational and economical use of energy : primary and noble (electricity) energies and reduced use of CFC. The equipments are : an innovative humidification air conditioning system which heats or refrigerates the treated air, the comparison of enthalpie for air mixing, the high-efficiency lighting (first building in the Belgian public sector), a cogeneration installation and a refrigerating absorption group associated with this equipment. A full DDC centralised management leads, supervises and operates these installations. This paper explains the choice of the cogeneration type, its exploitation and the results. The savings are large. A follow-up convention with ELECTRABEL (Belgian company for public production, transmission and distribution of electricity, gas, teledistribution and water energies) must optimise the working in order to increase the installations interest.
