As part of the 80th anniversary of IETcc-CSIC, a proposal for the rehabilitation of the 1953 building is made. The analysis of the main building’s energy performance concludes that it is not energy efficient.
Energy efficiency improvement measures based on European directives are proposed, It is recommended to incorporate them step by step, starting with passive measures to reduce energy needs. Afterwards active measures, such as improving the performance of facilities, are proposed, so that the least possible amount of final energy is used to meet the comfort standards. To complete the operation, the use of renewable energy sources is proposed to reduce the consumption of non-renewable primary energy.
Energy and building rehabilitation improvement measures in the IETcc-CSIC should be demonstrators for other public buildings with heritage values.
