The standard of passive houses was developed in middle Europe but also in countries with latitudes over 60° people was trying to realize building which “heat themself”. The standard was adjusted for colder climate and different techniques were getting invented to keep the houses in artic conditions warm. Among others in Finland passive houses arebuilt nowadays and getting more and more popular. A good insulation, an efficient ventilation system with heat recovery and clever devised heating systems make a passive house efficient and rentable. The invest is mostly not more than 10% higher as a usual building and the payback is often after 6 years already achieved. 10.18720/CUBS.13.2 69 passive house ground source heat pump ventilation air heating underfloor heating pellet stove energy consumption heating power https://unistroy.spbstu.ru/article/2013.13.2/ 2_passive_houses_13.pdf

 The innovative technology for erection of wall constructions of autoclaved aerated concrete blocks on polyurethane adhesive Masonry of autoclaved aerated concrete blocks is used in the construction of exterior and interior wall enclosures of modern buildings for both high-rise and low-rise private types. However, the construction of walls from small gas-concrete products (blocks) it is necessary to use the cement mortar (fastening in masonry blocks with each other). Mortars that are usually used for that purpose is either cement-sand mortar or thin-bed adhesive cement. Due to the fact that the thermal conductivity of cement mortar used to bond masonry blocks is much higher than thermal conductivity of the cellular concrete grades with density D400-D600, the presence of joints in the masonry cement leads to the formation of "thermal bridges". Thus, masonry joints cause additional loss of thermal energy which, when using thin glue can reach 10%, while using sand-cement mortars - 30% additional cost of heat energy compared to cellular concrete. Additional heat losses lead to a need to increase the rated capacity of the heating system and as a consequence, an increase in consumption in the building heating energy during the heating season. For this reason,to further improve the laying of concrete blocks it is required to develop fastening masonry structures characterized by low values of thermal conductivity. One of the options for improving the thermal insulation properties of aerated concrete masonry units is to use one-component polyurethane adhesives with thermal conductivity much lower than thermal conductivity of autoclaved aerated concrete blocks. 10.18720/CUBS.13.3 69 product unreinforced wall of autoclaved aerated concrete one-component polyurethane adhesive performance of works thermal conductivity of masonry resistance to compression of masonry fire-resistance of walls https://unistroy.spbstu.ru/article/2013.13.3/ 3_gorshkov_vatin_13.pdf

 Planning of construction works on the basis of a real estate’s systematic survey The issues of volume and scheduling of construction works on the basis of a systematic approach were considered in this paper. Models of assessment of costs were analyzed. Methods of scheduling of repair and construction works based on the creation the modules of time schedule depending on the species of works was proposed. The study determined that during the preliminary investigation of the facility can be used two models of calculating the cost of repairs depending on the value of the physical deterioration: linear dependence and polynomial of high degree. Also it was revealed that value planning and scheduling of repair and construction works has its own specific character due to different in time physical deterioration of the structural elements of the building. 10.18720/CUBS.13.6 69 structural survey polynomial physical deterioration repair costs scheduling information base https://unistroy.spbstu.ru/article/2013.13.6/ 6_morozova_bokovaya_khazieva_13.pdf
