The project idea aims to demonstrate the benefits of energy efficient (EE) materials and constructions to the citizens, by creating a platform that will offer concrete estimates of the cost-effectiveness of applying ЕЕ in their homes through an online application. The idea is to add new types of buildings – 10 different types of residential homes in the territory of the Ćuprija Municipality – to the already existing Energy Management Information System (EMIS) database of municipal/public buildings, from low EE buildings to high EE ones, with detailed description of the construction. Their energy consumption, external and internal temperatures would be continuously monitored and would serve as the basis for analytics. Citizens who wish to participate in these measurements will be offered instructions on how to install sensors by themselves, or they could connect ready-made sensors to their computer. The data and maps will be located on the project’s website. By cross-referencing data from the database with the entries of data on their homes made by the citizens through an interactive questionnaire, the software would generate answers to their queries in real time (which would otherwise require complex and expensive projects), and calculate, for instance, the return on investments in insulation or in transitioning to other types of heating and similar. The idea is to make the platform available to the citizens free of charge, and also to involve the corporate sector, the banking sector and the state.
