Growing vegetables in cultivation facilities can significantly increase the yield of products compared to open ground. Information data on greenhouses offered by producers for farms is summarized. The main types of farm greenhouses are identified, and they are compared for possible heat losses during the cold period of the year. It is established that with an equal building area, the area of enclosing structures of multi-span greenhouses is less than that of single-span frame and arch type. The formula for the minimum coefficient of fencing for a multi-span greenhouse, which provides a minimum of energy costs during the heating period, is derived. The structural scheme of the steel frame of a multi-span greenhouse of construction production from rolled profiles is proposed. It allows to significantly reduce the cost of construction of the structure in comparison with the cost indicators of greenhouses of factory delivery. The dependences of steel consumption for structural elements of the frame as a function of load and its construction parameters are obtained. Based on the obtained dependencies, the rational values of the span and step of the block greenhouse racks for snow loads specified in the building design standards of greenhouses are established. For rational values of planning parameters of the cultivation structure, specific indicators of steel consumption and cost per greenhouse frame are given.

Engineering services nowadays account for between 20 and 60 per cent of the cost of construction, and are a major factor in operating costs of buildings. They must be provided as economically as possible and in proper relation to the design of the building and the needs of the users. The paper explores this theme from two aspects (1) thermal conditions, and plant sizing in relation to building design and (2) standardization of services for specific building types. The general effects of structural mass and window design are first discussed briefly and it is shown how these factors affect the temperature within naturally ventilated buildings in summer. Nominally sealed buildings are then considered and the size of refrigeration plant required for an office is discussed in terms of similar factors and in relation to the design conditions. Such relationships should be taken into account during sketch plan design. The paper considers service cores in multi-storey buildings, where the plan of the building lends itself to a measure of standardization in the services. This theme is developed with particular reference to mechanical ventilation for the service cores in a 17-storey block of flats. Some details of this installation are given and used as a basis for discussing standardized services. Greater use of such systems, designed on a once-for-all basis and catalogued, would reduce the effort devoted year by year to similar design situations. The examples used are drawn from current work of the Building Research Station.

Abstract The objective of this study is the comparison of green roof systems with conventional isolated and non-isolated ones in order to identify the potential energy savings of green roofs and the benefits provided in comparison with the cost of construction to the buildings. The region of interest is the Watergraafsmeer area in the city of Amsterdam. The method evaluates literature reports - mostly from 2003 to 2010 - that present the advantages of green roofs. Examples in real implementation of green roofs in USA, UK and Germany, retention of rainfall and a Life Cycle Assessment from a residential construction in Madrid will be introduced, showing the energy savings from insulation and heating/cooling that can be gained. All the reports have shown a reduction in energy costs and in runoff of water. Hence, costs and retrofitting potential completes the research. The age of buildings and the absence of insulation make green roofs an ideal alternative project for the retrofit of Watergraafsmeer.

The problems of definition of the cost of design in construction are considered in the article. The existing regulatory documentation for determining the value of construction products on the territory of the Russian Federation is analyzed. A comparative analysis of the currently used methods for calculating the cost of designing is executed. The advantages and disadvantages of each method are considered, and the necessity of transformations in the sphere of determining the cost of design works is substantiated. The ways of increasing accuracy of calculation of the cost of design in construction are suggested, including the use of the territorial coefficient in calculations when utilizing the method of dependence on the natural indicators of the design objects. It is revealed that the use of this coefficient significantly increases the accuracy of calculations. For the method of calculating the cost of design as a percentage of the total cost of construction, it is proposed to clarify the methodology for calculating the cost of construction of multi-apartment buildings according to the enlarged construction price standards. It is proved that today it is impossible to replace the value of individual structural elements of an object in the event of differences in the design solutions with the solutions represented by similar objects in the collection of the construction price standards. The ways of solving these issues by the use of collections of standards for the price of construction solutions are outlined. The authors are convinced that the improvement of methods for calculating the cost of design products will improve the efficiency of investments in the construction industry.

The second part of the translation has three segments. The first is dedicated to the history of Delhi from the time of the Mahabharat to the periods of Anangpal Tomar to the Mughal Emperor Humayun as also Sher Shah, the Afghan ruler. In the second and third segments Mirza Sangin Beg adroitly navigates between twin centres of power in the city. He writes about Qila Mubarak, or the Red Fort, and gives an account of the several buildings inside it and the cost of construction of the same. He ambles into the precincts and mentions the buildings constructed by Shahjahan and other rulers, associating them with some specific inmates of the fort and the functions performed within them. When the author takes a walk in the city of Shahjahanabad, he writes of numerous residents, habitations of rich, poor, and ordinary people, their mansions and localities, general and specialized bazars, the in different skills practised areas, places of worship and revelry, processions exemplifying popular culture and local traditions, and institutions that had a resonance in other cultures. The Berlin manuscript gives generous details of the officials of the English East India Company, both native and foreign, their professions, and work spaces. Mirza Sangin Beg addresses the issue of qaum most unselfconsciously and amorphously.

Policies to reduce carbon emissions are leading to substantial changes in the demand for electricity and to the structure of electricity supply systems, which will alter the cost structure of electricity supply. This can be expected to result in corresponding changes to the price structure faced by customers. This note is an initial exploration of how possible new price structures may impact on HVAC system and building design and use. Changes in the price structure of electricity supply (separately from changes in price levels) can significantly affect the cost-effective design and operation of building services systems; especially of heating and cooling systems. The nature and implications of these changes can have important implications for future system design and operation.

With the widespread application of asphalt mixture, current demand from transportation managers for construction and maintenance of their pavement network consumes large numbers of aggregates. If agencies excessively favor to some certain kinds of excellent aggregates, the cost of construction could be considerably expensive. The major objective of this study is to determine the feasibility of utilizing dacite in asphalt mixtures. By means of Marshall, freeze-thaw, rutting and three-point bending tests, the performances of dacite and basalt asphalt mixture are compared. The results of the testing illustrate that dacite asphalt mixture is more susceptible to gradation and asphalt content than basalt asphalt mixture. Meanwhile it is showed that the performances of dacite asphalt mixture can be improved greatly with the involvement of additives including active mineral powder and cement. Furthermore, it is validated that dacite can be used as alternative aggregate in asphalt mixture.

Environmental and resource limitations provide increased motivation for design of net-zero energy or net-zero CO2 buildings. The optimum building design will have the lowest lifecycle cost. This paper describes a method of performing and comparing lifecycle costs for standard, CO2-neutral and net-zero energy buildings. Costs of source energy are calculated based on the cost of photovoltaic systems, tradable renewable certificates, CO2 credits and conventional energy. Building energy simulation is used to determine building energy use. A case study is conducted on a proposed net-zero energy house. The paper identifies the least-cost net-zero energy house, the least-cost CO2 neutral house, and the overall least-cost house. The methodology can be generalized to different climates and buildings. The method and results may be of interest to builders, developers, city planners, or organizations managing multiple buildings.
