Estimation of energy efficiency of residential buildings

Abstract

Abstract. Increasing energy performance of the residential buildings by means of reducing heat consumption on the heating and ventilation is the last segment in the system of energy resources saving. The first segments in the energy saving process are heat producing and transportation over the main lines and outside distribution networks. In the period from 2006 to 2013. by means of the heat-supply schemes optimization and modernization of the heating systems. using expensive (200-300 $US per 1 m) though hugely effective preliminary coated pipes. the economy reached 2.7 mln tons of fuel equivalent. Considering the multi-stage and multifactorial nature (electricity. heat and water supply) of the residential sector energy saving. the reasonable estimate of the efficiency of the saving of residential buildings energy should be performed in tons of fuel equivalent per unit of time.

Solar energy for self-contained power supply

“…• power converters operation control, generated electricity parameters regulation [11]. Photovoltaic method is preferable for self-contained low power solar plants (hundreds of Ws to tens of kWs) because of its constructive simplicity, which makes it more convenient to operate.…”

Energy Resources Consumption Minimization in Housing Construction

“…The idea of saving energy during the buildings operation is popular and is being realized in the whole world [1][2][3][4][5][6][7][8][9][10][11]. There have already been built the first experimental buildings with zero energy consumption (Null-Energie) [1,3] and with their positive balance (Plus-Energie) [4,8].However, the economically feasible construction of such buildings requires additional research.…”

Determination of acceptable limits of adjustment of heat consumption loading

“…In the presence of an intelligent superstructure with automated control systems of technological processes in control systems, the optimal temperature averaging period is determined by a number of factors characterizing the structure of the heat network connected to the heat source and the structure of the connected load [2,3].…”
