As part of the implementation of the international project “Green Construction in the Arctic” (KO 1089 - GrAB) of the Kolarctic 2014-2020 cross-border cooperation program, it is planned to construct experimental buildings (“model objects”). To implement the measures included in the GrAB project, it is planned to build two identical buildings on the territory of Murmansk and Petrozavodsk. The buildings are designed for research in the field of “green” technologies and energy-efficient construction, as well as approbation of research results. Objects in Murmansk and Petrozavodsk should be identical in external architectural appearance, design solutions and materials used, which will allow us to study the effectiveness of the use of the same building materials and structures in different climatic conditions. The model object is a one-story wooden house, its size in the plan is 13x6 m. It is envisaged to use modern technologies of wooden housing construction and equipping the house with energy-efficient engineering equipment, as well as a special temperature and humidity monitoring system for research. The facility is intended for conducting research in the field of green building technologies, testing new technologies and evaluating the effectiveness of their work in the Far North (Murmansk) and adjacent territories (Petrozavodsk). Purpose of work: a comprehensive assessment of the influence of the structure of the walls of a wooden house on its energy supply.

The article presents an analysis of international and national “green” buildings certification systems from the point of view of the possibility of their use in the Arctic territories. The groups of criteria that are typical for most certification systems, as well as the most significant groups of criteria for all considered assessment systems, have been identified. The main groups of criteria were correlated with the requirements for buildings of the settlements sustainable development program and with the stages of the buildings and structures life cycle. As a result of the performed analysis, conclusions were formulated about the need to focus on certain key and characteristic criteria or their groups for the Arctic territories in the system of environmental assessment of buildings.

The specified terms in the summary report "Energy saving" and "Energy Efficiency". Energy saving is considered as a system of organizational measures, technological and technical solutions that provide a reduction in energy consumption and other resources without compromising the quality needed energy consumer. Energy efficiency is largely determined by economic and other quantitative characteristics obtained as a result of the implementation arrangements, technological and technical solutions that provide a reduction in energy consumption, water and other resources in relation to the volume of products and services. It takes into account that the energy efficiency of any building depends on a combination of factors such as: architecture, insulation, air tightness, ventilation and quality of design and technological solutions and the execution of works. In conclusion, it is stated that by using energy conservation principles, it is possible to significantly improve energy efficiency, and ideally design the building with a zero energy balance.
