INNOVATIVE FRAME WOOD CONSTRUCTIONS CONCEPT FOR HIGH ENERGY EFFICIENCY ECOBUILDINGS
Keywords:wooden building constructions, energy efficiency, eco-technologies
The aims of the research are to investigate the durability and compliance of patented innovative low or zero heat energy consumption buildings constructions by Latvian construction standards. To develop and study high-quality, energy-efficient and long-lasting low-cost eco-buildings construction technology by using locally sourced building materials and involving local labour, using various low-cost recyclable ecological materials and their recycling residues as eco-thermal insulation. Because of the research, it was established that by using building materials of appropriate size cross-section - spruce boards and interconnecting them with screws, it is possible to make a sufficiently strong building construction frame where are in accordance with Latvian construction standards by using a significantly smaller amount of building materials. By filling the frame of the innovative construction building with thermal insulation in the appropriate thickness, it is possible to build up houses with high energy efficiency that correspond to the parameters of low or zero heat energy consumption buildings. In climatic zones, where for buildings have increased energy efficiency and thicker layer of thermal insulation requirements, it is expected that double windows and doors design solutions will be used to reduce heat loss of cold bridges, and the air gap between them increase the energy efficiency of buildings.
