There live about 80,000 inhabitants in 20,000 flats. The 15 buildings in this project, with a total of 1,500 flats were built in 1964-65. The framework is pre-cast concrete elements and walls are of plastered lightweight concrete. The roofs are flat and have many leaks causing considerable energy losses. There are no control possibilities available in the substations or in the apartments.
Ventilation consists of natural draught.
The buildings are owned by co-operativs. The actions are various and will consist of the following measures, renovation and insulation of the roofs, renovation of wall elements joints, insulation of gable sections, installation of new substations with control equipment and heat exchangers for both heating and domestic hot water, hydraulic balancing by means of balancing valves in the risers, installation of thermostatic radiator valves and chemical cleaning of the internal heating system. Methodological work will be required to determine for each type of activity what the minimum data requirements are. 15 years Conversion of existing boiler but new installation fuel handling system and firing equipment. Modernisation of secondary equipment.
