Abstract. Energy efficiency building envelopes (walls, floors, facades) should meet the requirements of regulatory documents. The main attention is paid to structural and technological activities aimed at increasing the thermal resistance of protections. Estimates of the thermal stability of the wall are required for realization of high thermal resistance of the wall structure. The object of study is a simple model of the building envelope. It has been shown that the increased thermal conductivity, thermal resistance does not always provide the steady-state temperature faces the wall. Research method is based on the analysis of the properties of the Cauchy problem. In this article it is found out the connection between the active (thermal resistance) and reactive (accumulation) resistance enclosure on the model of one-dimensional wall.Аннотация. Энергоэффективность ограждающих конструкций (стен, перекрытий, фасадов) должна соответствовать требованиям нормативных документов. В настоящее время основное внимание уделяется конструктивно-технологическим мероприятиям, направленных на увеличение термического сопротивления ограждений. Реализация повышенного термического сопротивления стеновой конструкции требует оценок термической устойчивости стены. Объектом исследования является многослойная ограждающая конструкция. Показано, что повышенное термическое сопротивление теплопроводности не всегда обеспечивает стационарность температур граней стены. В работе описывается важность следующих факторов: оптимизация температурно-влажностного режима стен; влияние включений на величину потерь теплоты; влияние двойных фасадов на тепловые потери; эффективность применения новых теплоизоляционных материалов на термическое сопротивление и энергоэффективность. В данной статье выясняется связь между активным (термическое сопротивление) и реактивным (аккумуляция) сопротивлениями ограждения на модели одномерной стенки.
Construction industry is an influential element of Russian economy. It is well known that the main objective of construction for a builder is receiving profit in the form of a difference between the received investment contributions and size of construction cost. Therefore maximum efficiency from implementation of a project will be received by a builder who will carry out construction of the most investment-attractiveness object.Investors do not use certain formalized analytical tools for assessment of situation in regions where a construction object can be potentially placed in most cases. Frequently, investors make the decision on building placement, which based on subjective representation about investment-attractiveness of specific region.The goal of this research is analysis of investment-attractiveness of high-rise building with building site in case of placement in different regions of Russian Federation according to method of A.L. Kaminskiy, including additional unique characteristics of the object.
The article presents a renovation project of a residential area: Mannheim, Germany. The plot size is 6.4 hectares. It includes Glückstein-park area adjacent to the historic buildings, as well as the south - eastern part of the quarter Glückstein. Territory selected for the design, located opposite the railway station. This area has the highest priority in the planning of the city, as it connects the neighborhood Lindenhof district and the city center. The project includes a number of design features that incorporate the social and economic aspects. The main expected result of the renovation is a well-designed a unique energy efficiency, functional and expressive architectural complex that serves a residential area. Architecture new objects fit into this area. Urban space located near the quarter was designed. The proposed preferred embodiment, more comfort improvement throughout, including a high level of landscaping.
