“…It should be noted that similar results were obtained in the article "Justification of constructive measures to increase energy efficiency of wall barriers" [15]. The conclusions of this work indicated that materials with high thermal conductivity play the role of a heat storage device.…”

“…Stationary measurement is a mode in which all considered thermal parameters do not change with time. A method based on the regularities of stationary thermal regime, as shown by theoretical and experimental studies [15][16][17], provides greater accuracy and reliability of determining the true value of λthermal conductivity. Measurements can be made in a wide temperature range-from 20 to 700 °C.…”

Thermal Properties of Conventional and High-strength Concrete

et al. 2018

Important characteristics for the Nordic countries: a freeze-thaw resistance and an ability of a material to keep heat inside the building. This paper aims to define the thermophysical properties of a high-strength concrete, compare the discovered performance with the conventional concrete properties. With this object in mind two experiments in cold chamber “CHALLENGE 250” have been conducted and followed by analysis. In these experiments, the insulation of facades is beyond the framework of the investigation. Only the thermophysical properties of concrete are taken into account. The samples were affected by temperature fluctuations. Results from the experiments show that strength characteristics of a material are in indirect ratio to accumulation properties of a structure. This conclusion is directly related to porosity of material and additives. During 70 minutes, with outside temperature being below zero, the temperature inside the concrete dropped to an average. As the outside temperature increases significantly to more than zero, the temperature inside the concrete has become below average (continued to decline) in 70 minutes. The more strength of material, the better thermophysical properties. High-strength concrete is less susceptible to temperature fluctuations, therefore more heat-resistant. As mentioned in the paper below, the material has one disadvantage: this is a large cost per cubic meter.

“…Тепловая защита здания, следовательно, и его энергетическая эффективность во многом зависят от теплотехнической однородности ограждений [8]. Теплотехнические расчеты показывают, что заменяя тяжелый бетон в несущих конструкциях зданий на низкотеплопроводный легкий, можно существенно выиграть в теплотехнической однородности ограждения и, следовательно, либо в сокращении расчетной толщины наружной стены на 10-20%, либо при сохранении толщины -в снижении энергозатрат на отопление здания, а именно в повышении его энергоэффективности [9].…”

The article analyzes the existing data on the use of organic additives in concrete in order to improve its thermal characteristics. The most promising types of additives for reinforcement have been identified, a series of experimental studies have been carried out and data on the strength and thermal characteristics of the obtained concretes have been obtained. Detailed conclusions and recommendations on the application of the obtained results are given.

“…In table. 1 technical characteristics of typical projects of the OD series are presented [17][18][19]. In houses with three-layer walls warming of horizontal joints should be made removal of the crude or sifted insulation, drying of a cavity with replacement of a insulation and consolidation of a joint by expanded clay concrete of quality class number 50.…”

In this article the technique of determination of payback period of investments taking into account capital costs and economy of means at the expense of implementation of energy saving actions for warming of external protecting designs is considered. Presented in the article the method of assessing the return on investment in the implementation of energy-efficient solutions of facade insulation is only evaluative. For more accurate calculations it is necessary to take into account the discount rate. Nevertheless, the main factors that have a positive impact on reducing the payback period of investments in the renovation of facades are identified. Only an integrated approach to improving the energy efficiency of buildings can not only reduce the cost of operation of buildings, but also provide a reduction in the payback period of investment in the implementation of energy efficiency measures.
