Abstract: The national green building evaluation is divided into two phases of design and operation label. Because of involving many units, complicated operation and long construction, it is difficult to achieve the whole process identification of green building.It refines the assessment process of green building into conceptual design, predesign, construction drawing stage, green construction, completion and acceptance of construction, operation and maintenance respectively.Furthermore, the detail requirements and implementary strategies are expatiated in the article, combined with related theory and engineering design. Additional, it analyzed on green strategies of evaluation based on an actual engineering to provide a reference for green building assessment.

Abstract: This paper introduces the form of materials of the light ceramsite foam concrete insulation block, product specifications, production technology and product properties .Discusses the construction of self thermal insulation wall system construction.

Abstract: This paper aims at explaining testing procedures used to evaluate the potential of natural ventilation and daylighting applications to passive design of housing in Ghana. The objectives of research were to reduce energy costs and increase the sustainability of housing. From the results of these experiments actual and potential designs are illustrated and discussed. Mass housing results in multi-storey buildings which require substantial artificial lighting and ventilation. Also, with the increasing usage of glass for windows and doors in Ghana, even the shaded depths of buildings require additional daylight usually resulting in more energy consumption. By supplementing the internal lighting levels with daylight, reducing the internal heat load by shading windows to direct radiation and the utilization of natural ventilation over air conditioning where possible, significant energy savings are could be achieved. The research proposes mass housing design changes such as: delivering daylight above the suspended ceiling into the depths of the building by horizontal light pipes and natural ventilation, utilizing stack effect and wind siphonage, etc.

Abstract: The purpose of the paper is to research and analysis energy-efficient technology suited the residential building and energy consumption level of building, master the application of energy saving technology in building, thus provide the basis for energy saving and integrated application of adaptability in different buildings. The basic materials of residence in Shenyang were collected by the form of survey analysis, at the same time, evaluation and analysis of the energy consumption data. Through the investigation and building self assessment index analysis of the heat consumption, to achieve the requirements of the energy saving 65%.Building is obviously relevant to climate, and 90% of electricity consumption for appliances and lighting. There is a lot of energy waste with 40% of the building water consumption for flushing. Through to the analysis of the residential energy consumption, the key to energy saving of residential building are the thermal performance of the building itself, make full use of natural light and other measures, and improve the energy consumption of the system in the building and equipment efficiency.

Abstract: More researchers pay attention to energy consumption and conservation in cities before .This paper finds out the current structure of rural houses, the type and utilizing situation of energy and the typical heating methods in current northen rural areas of china, and points out exist problems in these aspects by Field investigation and analysis.The author proposes that insulation layers of external walls and windows are preferred measures of energy consrevation and the additional southen sunspace is also a highly effective method in northen rural areas; the hanging kang has a much better performance than landing kang which should be strongly recommended,and a new kang with PCM helps to save fuel consumption, increase temperature uniformity of kang surface , stabilize indoor temperature and improve indoor thermal comfort,which should be paid enough attention; the effective use of excess heat in solar energy water heater should be paid sufficient attention,and biogas should be strongly advocated and properly guided.

Abstract: In order to meet farmers’ energy demands of gas, domestic hot water and winter heating with renewable energy in rural areas, according to farmers’ living habits in winter, a 30m2 insulated rural green building made of brick and concrete, was developed to integrate with thermostatic digester heated by solar energy and low-temperature radiant bed. Energy expenditure and thermal economy of the green building were studied at different winter ambient temperature subsequently. The results show that the consumer’s energy demands of gas, hot water and winter heating can be met in the green building even in winter. When the outdoor temperature is -20°C, the indoor’s is higher than 15°C. Compared with traditional rural buildings made of brick and concrete, the new one saves 2.8 tons of standard coal and RMB￥3275 every year and the payback period of investment of the enforced cost is 3.9 years.

Abstract: Nowadays, green building, which has a rich connotation, has become a combined concept of natural, cultural and economic aspects.The humanistic concept of green building is the soul of the green building. The economic view of green building based on the humanistic concept includes"economy"and"application", which are of important practical significance. This paper mainly elaborates economic concept and applicable function,to deepe- n the understanding of economic view of green building.

Abstract: Investigations have been conducted on the mechanical properties of bamboo-aluminum sandwich composites prototype fabricated in laboratory. Mechanical properties studied were flexural properties and impact properties. The failure mode related to each mechanical property was also observed and reported in this study.

Abstract: Two office buildings in Montego Bay Jamaica were investigated in order to assess indoor environment and visualize building energy usage. The field survey was performed to obtain first hand data of occupant perception of their actual working environment. In this paper, the energy break and historical energy usage for the years 2010 and 2011 are presented. A questionnaire which was developed at the American Society of Heating, Refrigerating and Air- conditioning Engineers (ASHRAE) was modified and randomly issued to 210 building workers at both buildings. On examining the equipment currently being used in these buildings a building Energy Index (BEI) was used to identify and quantify inefficient of energy consumptions in both buildings. The results showed that the energy performance of the Internal revenue Department (IRD) is not in an efficient condition. However, the St. James Parish Council (St.JPC) is within the targeted BEI .The research also revealed that HVAC was the most energy consumptive in both buildings, followed by lighting, office equipment and Miscellaneous. We suggested that a comprehensive program of efficiency, improvement and energy diversification is required in Jamaica to provide high quality, affordable, environmentally-friendly energy and reduce the country’s dependence on high cost imported oil.
