Pastatų energijos poreikių valdymas Lietuvoje

Abstract

Buildings, that for the most part are dwelling houses, represent the greatest wealth of each country. The overall area of residential buildings in Lithuania in 2004 was equal to 93 million square meters and of the public buildings approx. 30 million sq.m . These invaluable assets have been developed through centuries. The results that we see today and will see in the future depend on our building practice, traditions, economic welfare and specific climate conditions. On the other hand, Lithuanian buildings and service sector buildings consume more than 46% of final energy and accordingly the building owners spend over 2.5 billion litas each year. One of the essential requirements for buildings is their energy properties. They are formed during all the phases of the building life cycle. The design and construction process should guarantee sufficient energy indicators for new buildings. The maintenance process should ensure the efficient use of existing buildings, their renovation and modernization. The task of State and local government is to bolster the ability of building owners, managers and others market participants to maintain, renovate and modernize buildings and improve their energy parameters. To ensure sustainable development, one should adopt an integrated approach to energy production and consumption chain. The improvement of buildings energy supply systems, the preservation of buildings value and their rational use are identical goals both for owners and the State that solutions require knowledge and well-balanced mechanisms. This paper presents qualitative criteria for the building sector as well as measures to solve this problem.
