In the early days of 'De Uithof' architect Sjoerd Wouda designed two
small buildings that were meant to provide the energy to warm the
university buildings. These reversed funnel shaped buildings were
originally meant to contain only large gas heaters. The heat was
transferred to the buildings by means of a system of pipelines
through which hot water ran at 120 degree centigrade. The two buildings
go without proper names, they're just known as WKC1 and WKC2.
From 1985 the use of the buildings was changed. Large gaspowered
engines were installed by means of which both electricity and heat
could be produced, a principle known as cogeneration (CHP, combined
Heat and Power). The combined production of heat and power is very
effective: a performance of around 80% can be achieved which is
about two or three times more effective than the tradional power
plant. Utrecht University has taken the production of 'green' (or
in this case 'blue') energy seriously for over 20 years.
