THE ROLE OF DISTRICT HEATING AND COOLING TECHNOLOGIES IN ENERGY PROVISIONS FOR BUILDING SECTOR: CHALLENGES AND PERSPECTIVES

District heating and cooling technology finally is recognized at European level as promising tool for implementing energy and environment policy goals. At the same time new approach towards traditional concept of DH systems should be elaborated based on recently adopted European energy policy targets in the field of energy efficiency, renewable energy and environment. New challenges for district heating and cooling (DHC) sector are related to the possibilities of large-scale integration of renewable and local energy resources, creating an energy infrastructure capable to integrate different distributed heat producers, together with ability to be competitive against emerging distributed heat generating technologies. The paper addresses evaluation of main DH sector characteristics and management practice and suggests necessary changes for the sector development policies. DHC perspectives were analyzed with regard to identification and existing shortages and barriers in energy policy in European context with particular focus on Lithuanian DH sector. The methodology principles of DH sustainability and viability is provided taking into account energy efficiency and green labeling approach. The background of further DH development strategy is provided based on comparison of the DH characteristics in European context and devoted sector role in implementation national energy strategy and policy targets.
