The scientists and researchers of the Institute, together with their partners, are looking for innovative methods to ensure the quality and energy efficiency of building materials.

 

Research areas

Scientific research in this field and its results are devoted to the study and evaluation of Lithuanian architectural and urban heritage.

Research and its results is intended to develop new and to improve current methods of assessing the durability of building finishing materials after mechanical and environmental impact assessment.

Scientific research in this field and its results are devoted to the study and evaluation of spatial planning, landscape formation, and changes in the spatial structure of residential areas.

Research and its results are intended to create new structural solutions for energy-efficient buildings, to analyse the possibilities of efficient use of the produced solar and wind energy for the building’s energy needs; to improve the methods of assessing the durability of building finishing materials after mechanical and environmental impacts.

 

Scientific achievements and impact

Research carried out in the Institute is significant to the science of civil engineering and experimental development. The outcomes and results of the research are used in the designing energy efficient buildings and their engineering systems, raising the professional qualifications of construction specialists, preparing normative documents in the field of construction. The research activities of the institute in these areas are aimed at strengthening the links with business and state institutions, at attracting and promoting doctoral students, at expanding cooperation with Lithuanian and foreign partners; the Institute’s research production contributes significantly to the country’s economic and energy development.

National projects

Heritage as a Conflict: Differences of the Concepts of Modernist and Post-Modern Heritage Protection in Lithuania”, Project Manager Dr V. Petrulis

The source of funding: Research Council of Lithuania, Researchers’ teams projects. Duration: 2015.04–2018.03. A monograph is being prepared during the project, which is based on international experience and taking into account the specifics of Lithuania. It will identify the dissonances arising from the combination of contemporary heritage protection processes in Lithuania and the tasks set in the international heritage policy. Depending on the case studies that reveal good practices, selected during the study, methodological principles will be provided, in the international space that would allow neutralising these dissonances through the formation of Lithuanian heritage protection policy
