Energy in the economy of Serbia, overview of the legislation in the production of heat energy, DHS general data about fuel used, how much heat can be provided from renewable sources?, is there a possibility of incentives for the production of heat energy from RES?, business results of Serbian DHS, current impacts on the "market" of heat energy, how to reduce the cost of heat energy?, changing the structure of fuel in the production of heat energy 2010-2030, legislative framework for the implementation of energy efficiency measures, etc.

Legal framework for energy efficiency in building, energy policy of the city of Šabac and its goals (estimated that up to now, 25% of collective housing has been through the process of improving energy efficiency: 46 multi-family, 40 single-family, 1,400 apartments ), incentive measures for energy efficiency application (energy efficiency measures are financed by a special revolving budget fund, and the money is spent on the basis of the budget fund program of the city of Šabac), recommendations for further improvement of DHS, etc.

Data on heating plants that participate in the district heating system of city Šabac, district heating report, the most important investments in the revitalization of district heating, biomass in response to growth in natural gas prices, heat pumps as a new heat source, remote monitoring and management of heat substations

Examples of records and procedures are given, such as: list of reports - declarations of failures and interventions, algorithm for reporting behavior to Troubleshoot and procedures for communicating with users

Experience of the Laboratory for Thermal Engineering and Energy, Vinča Institute, regarding the realization of concrete projects - laboratory and demonstration facilities that use biomass as a fuel

Fact that regardless of how well the energy efficiency programs are well thought out, the realization is not possible if it is not discussed with the citizens, tenants reacted positively when they were shown images of thermovision cameras showing the walls which are not well isolated, which they linked to their observations of the colder parts ofthe apartment. That's why, he believes, it is crucial that a good team has to be selected to convince citizens of the benefits of thermal insulation and especially savings through reduced heating bills; the prerequisite is that the price of heating is paid for the heat consumed, not per square meter of the housing unit
