Increase of Energy Efficiency of the Building of Kindergarten

Abstract

In article the structural analysis of power consumption of the building of kindergarten is carried out, on the basis of the analysis of actual data of heatconsumption and the carried-out tool energy audit the data, allowing to estimate a condition of systems of heating, power supply, water supply are obtained. Actions for energy efficiency increase are offered. It is shown need and economic feasibility of performance of the organizational and technical actions offered to realization on economy of thermal and electric energy.

Specifics of Building Envelope Air Leakage Problems and Airtightness Measurements

“…The negative property of non-airtight buildings is uncontrolled cold air infiltration which requires also additional heat in time than room is not occupied. Existing researches [12,13,14] have proved positive effect of renovation works done in kindergartens and schools. However measurements done in Latvia [15,16,17] have shown significant increase of indoor air CO 2 concentration after renovation, which has negative impact on human health.…”

The using feasibility Russian and European software products at thermal calculations

“…The norms of energy buildings consumption is constantly are decreasing and the requirements to the insulation level of external envelope are increasing because of constant growth of energy resource prices, the growth of thermal energy tariffs and reduction of stocks of non-renewable hydrocarbons (oil, gas). Thus, one of the most important ways of economy of energy resources is the reduction of heat losses through the building envelope of buildings [16][17][18][19][20][21][22][23]. One of the problems is low awareness of designers about the global experience of design of energy-efficient buildings.…”

Sandwich Panel as a Structural Element of Overlap

“…But despite the obvious relevance of use of this material is limited. This is due to the fact that the thermal engineering calculation is widely studied [2][3][4][5][6][7][8][9][10][11], which allows us to use sandwich panels as walling. However issues of technological and regulatory plan and strength calculation remain open and require active discussion [12].…”
