Reducing Energy Consumption by Optimizing Thermal Losses and Measures of Energy Recovery in Preschools

The article deals with the problem of energy saving by optimizing heat loss and measures for energy recovery in the existing preschools. The paper presents a theoretical basis, simulation and computations - calculations of heating energy needs for established models, by using appropriate software packages. The program and development of models for improving energy qualities of the envelope, with the tendency of switching to renewable energy sources, are defined. The methods used in this paper include the method of modelling based on the digital simulation of the representative facility, as well as local visits and interviews with relevant researchers, policy makers and preschool educators. The survey is conducted through a case study on the territory of the City of Nis.
