TY - JOUR TI - Reasons for heat demand changes and effects on planning and development of heating systems AU - Petrović Jovan AU - Gvozdenac-Urošević Branka AU - Polc Josip J JN - Thermal Science PY - 2012 VL - 16 IS - 11 SP - 63 EP - 77 PT - Article AB - Planning the development of heating systems in circumstances of dynamic changes in the energy field is becoming very demanding from the aspect of consideration and involvement all impacts on the future development. The paper deals with a methodological approach towards the change of normatives which includes future conditions for the development and changes of heat energy consumption and possible scenario for the change of consumption in Novi Sad within the boundaries of capacities for future construction. The possible dynamics is determined and the projection of the existing consumption growth in the conditions of increasingly stringent energy circumstances for the further growth and strict energy requirements of contemporary moment.
