Straw construction presents some advantages such as renewability with low energy input, recyclability, CO2 storage, and local availability that implies short distribution cycle. However, before the introduction in the construction industry, attention needs to be paid to the construction technology using such natural materials. In this paper there were developed elements of enclosing structures for two technologies of straw frame building; was done thermal modeling of potentially weak assembles of building envelope; were calculated R-values and then compared with normative indexes; was evaluated efficiency of usability two technologies of low-raise building in cold and wet conditions of St. Petersburg.

This article describes passive and active measures of decrease of thermal loss through enclosure structures, usage of modern insulation materials; positive effect of rationalization of the façade orientation and form of a building in a plan; on the base of existing architecture concept structural solutions of building envelope are suggested. Using thermal FEA the enclosure structure was optimized. The results of modeling of units and elements of building envelope are: heat transfer coefficient U-value for heterogeneous multilayer structure, picture of temperature distribution and magnitude of the thermal conductivity and temperature of internal wall surface.

The construction industry is not an exception. Construction is the major the industry during the change of technological orders, and energy-efficient technologies are the core of technological order. The authors with the help of economic calculation show the replacement of technologies on the example of solar batteries and suggest the mathematical model of energy-efficient technologies demand.
В статье раскрывается одна из важнейших причин мирового экономического кризиса – смена технологического уклада (неэффективные старые технологии заменяются эффективными новыми). Строительная отрасль в этом смысле не является исключением. Строительство будет являться несущей отраслью при смене технологических укладов, а энергоэффективные технологии – ядром технологического уклада. Далее показывается, как будет происходить замещение технологий на примере солнечных батарей с помощью экономического расчета. Предлагается математическая модель спроса на энергоэффективные технологии.

Pasta were chosen as the base material. Their basic geometrical and mechanical characteristics were evaluated. Finite element analysis of the pasta frame structure was made in SCAD (Structure CAD) and ANSYS. The internal force factors arose in the structure were compared. Its actual carrying capacity was determined in virtue of the structural solidity and material`s experimental evidence. Also the features of optimized structure design were found, the assembly process was described, the test results of the construction were presented. The comparison of the results of finite element modeling and actual laboratory tests was done.
