Autonomous power installation with complex power effective electroproviding Application of natural gas for ensuring heat and electricity is actively applied in many settlements of the Russian Federation and is the most favorable resource. Networks of distribution of natural gas don't cover all volume of consumers and the question of accession to networks to become more and more sharp in view of a constant gain of again formed complexes of the housing estate remote from the cities and megalopolises, andconsequently and from network communications. Alternative of leading of network gas is the device of the autonomous (personal) gasification, capacities resumed by liquefied gas. This method involves big financial expenses which have a big payback period,occupy part of elevated and underground space of the expensive earth, and also demands attention regarding maintenance and that periodic replenishment of the tank by the liquefied gas, as private use is important, attracts the raised expenses on transportation.The technology of application of the liquefied gas for the centralized providing with energy resources of a complex of building remote from network energy resources is considered in this work, the economic-mathematical model of the first approach ofthe concept of the device of the settlement, allowing to determine the cost of received energy and equipment payback periods is offered. 10.18720/CUBS.10.1 69 autonomous power installation alternative source of power supply energy efficiency energy saving efficiency indices building energy saving investment payback period https://unistroy.spbstu.ru/article/2013.10.1/ 1_nemova_kurasova_rus_10.pdf

The accounting of the form at the assessment of the thermal performance of the envelopes This article is devoted to the solution of an actual problem — assessments of level of thermal performance of the building taking into account its form. The criterion of a thermal performance of envelopes on the basis of the basic resistance to heat transfer of envelopes is defined. By results of statistical data processing dependence of basic resistance to heat transfer of envelopes from an index of compactness of the building, allowing to define minimum admissible level of a thermal performance of envelopes at the set form of the building is received. On the basis of the developed technique it is shown that level of a thermal performance of the building depends on its form. Complication of a form of the building demands higher level of its thermal performance. Design of buildings of a compact form allows to lower reasonably level of a thermal performance of the building and has the high potential of energy saving. The received results of researches can be used when updating norms on thermal protection of buildings. 10.18720/CUBS.10.2 69 building form thermal performance of envelopes the specified resistance to a heat transfer index of the shape of a building selection of representative buildings https://unistroy.spbstu.ru/article/2013.10.2/ 3_korniyenko_10.pdf

The reasons of occurrence risks are not the full amount of information about the future. Distinction between risks and uncertainty: for understand we should know what conception has risks. Risk-probability a risk event, but if the question is about uncertainty, we can’t determine the likelihood of associated events. What assessment methods exist today?

Technique and technical and economic assessment of the optimized decisions on construction pricing Article is devoted to questions of calculation and optimization of cost of construction at a stage of budget planning. When the cost and terms of performance of work is counted it is necessary to optimize these criteria to minimize expenses, but thus not to increase duration and it is rational to use resources.Calculation of cost of building of Object, terms of performance of work, and also optimizing procedures on reduction of terms and the cost of performance of work is described in article. 10.18720/CUBS.10.6 69 construction tenders integrated criterion pricing budget https://unistroy.spbstu.ru/article/2013.10.6/ 7_malina_10.pdf
