As a fuel natural gas is used. Before installing CHP, heat consumption was higher than the primarily planned, losses of the heating system were high and the building was energy wasteful.

By installing CHP better energy efficiency and lower losses than before were achieved and energy costs and the level of CO2 emission were reduced. Heat is used for heating and preparation of sanitary hot water on-site only, while 80 % of electricity is used on-site and 20 % is sold to the grid.
