The project was carried out because of high price for heat and uncomfortable indoor climate. Heating system was one pipe system with no possibility to regulate on the radiator level. Ventilation was designed as natural from windows, but due to the fact that most of the apartments have already changed windows the natural ventilation does not worked properly any more. Heating system was unbalanced and heat supply to the radiators was unstable. At the same time support scheme for renovation was available.
Scheme terms were connected with energy saving % compared with last 3 years consumption. Conditions - 35% investment support means 50% savings. Association general meeting decided to go on 35% investment support. Flat owners are in 49% pensioners with reasonable low income (about 300 EUR month). Conditions foreseen that renovation should consist from total insulation of all external walls (U value 0,2) and roof (U value 0,15), installation of windows with U value not higher than 1,1. Heating system should be regulated on the radiator level, ventilation should have heat recovery element, flat based system was decided to use. Renovation project was designed for these conditions.
