Thermal Modernization of Public Buildings in Chernihiv with USAID Project Support
The USAID Project developed the feasibility study for implementing energy efficiency measures in 73 public buildings in Chernihiv. They include 38 kindergartens and 32 secondary schools, one medical building and buildings of two culture institutions.
The feasibility study considered three alternative options (packages) for implementing energy efficiency and technical measures. The first (maximum) package for 73 public buildings (81 buildings) calls for the implementation (fully or partially) of 21 proposed measures. The second (alternative) package of energy efficiency measures includes 25 objects (29 buildings): thefull modernization of 17 objects (21 buildings) with a complete set of proposed measures, except for the replacement of old stoves in the kitchens; three kindergartens with solar collectors installed for the hot water supply systems; and 5 schools which will have the old wooden windows replaced with energy efficient PVC windows and local forced-air-exhaust ventilation with recuperative heat exchange installed.
The third (minimum) package includes 71 objects (79 buildings) (except for cultural institution buildings). It envisages: replacing old wooden windows with energy efficient PVC windows; introducing local forced-air-exhaust ventilation with recuperative heat exchange; installing individual heat substations (IHS) with automated weather-based controls and programming/modernization of IHS; reconstructing and/or balancing of the heating systems. It also envisages the heat insulation of the pipelines and valves in the heating and hot water supply systems and introduction of the procedures for operation, maintenance and energy monitoring.
The Project recommends package # 2 for priority implementation and the taking out of a loan from the European Investment Bank. Implementing this optionwill give the maximum increase of energy efficiency in 17 buildings due to their comprehensive thermal modernizationand will eliminate the problems with humidity and ventilation in five schools. Therefore, this will resolve social issues and reduce the morbidity rate among school students, as well as will allow for the implementation of a pilot project in the city – introduction of solar collectors for the hot water supply systems in the kindergartens.
