Abstract: This paper presents the implementation of energy efficiency measures in a building that consists of office, lab and clean room area. Total Performance Oriented Optimization and Retrofits (TPORs) were implemented. 594 kW solar panels were installed on the roof and connected to the electrical grid during the optimization process. Ten power meters were installed throughout the building to measure the total building electricity demand, solar generated electricity demand, HVAC and non-HVAC-equipment demand to quantify the energy savings from the implementation of the energy efficiency measures and savings from the solar panels. The electricity savings from optimization on the HVAC system is about 7,209,000kWh/year (194.4kWh/m2-year), which is about 30% of the total building electricity consumption with peak demand reduction of 935 kW. There savings come from the solar panel is 811,925 kWh/yr; however, it effectively reduced the peak electricity demand by 302.6 kW.

Abstract: Building "short-lived" phenomenon is very common in China. It is extremely wasteful for a developing country with limited resources and financial resources (per capita). Any green low carbon, energy saving and environmental protection without building safety would like water without a source, and a tree without roots. Extending the building life, based on Chinese current situation, mainly starts out here from two aspects of new buildings and the existing buildings, and need strengthen government regulation. Fundamentally extend building life and promote building energy efficiency.

Abstract: The main reason for slow development of energy-saving buildings are differences in the benefit of all stakeholders to appeal. Identifying stakeholders, and on the basis of analysis all parties interests and needs, energy-saving building Life Cycle Cost-Benefit Model was established. Then we can find the equilibrium point among the government, developer and consumer, and factors of impacting the development of energy-saving buildings. Last we provide advice for the rapid development of energy-saving buildings.

Abstract: Recently the potential development of green architecture in our country is huge, but inaccurate control of green building’s incremental cost is the key reason for restricting its development. After analyzing influencing factors of green building’s incremental cost, four influencing factors are put forward:technical measures, project regions,fixed position and time to research feasibility. On basis of the factors, the ways are proposed to reduce green building’s incremental cost, which provides theoretical basis for the development of green architecture.

Abstract: In this paper a shading coefficient test platform using artificial light sources was developed to measure the shading coefficient of some typical shading products for building. The platform consists of three testing cases and a protective case. The results show that the detection period using this method was approximately 5-6 hours, and stability of repeating test was good. The experiment results of between-glass venetian blinds are compared with the simulation results to verify the scientific feasibility of the test method.

Abstract: Energy use in university campus plays an important role in energy use of the society, because universities are complex infrastructure and they are similar to small towns. A university campus consisted of 35 buildings, with total area of approximately 300 000 m² was analyzed. Six-year energy uses of electricity and heating of 24 buildings in one university campus in Norway were selected as case objects monitored by Building Energy Management System and web-based Energy Monitoring System. Descriptive statistics were applied to analyze energy use and influencing factors on energy use. The coincidence factors for both heating and electricity were calculated. The results indicate that the energy use of the whole campus were obtained as101 kWh/(m² a) for heating and 200 kWh/(m² a) for electricity, respectively. Regarding the individual buildings, the electricity use was 170± 89 kWh/(m² a) and the heating use was 169± 115 kWh/(m² a) for heating with a few exceptions of over 300 kWh/(m² a). The influence of seasonal factor on heating was much higher than on electricity. The coincidence factors of heating were 0.96 in working day and 0.87 in weekend. The coincidence factors of electricity were 0.99 and 0.98, respectively. The results from the study could be used for energy planning of cities and other urban energy systems.

Abstract: The text elaborates on the significance and profile of insulation system for external wall of residential buildings in our country, makes comprehensive comparison among the external wall's self-insulation system, external wall's internal insulation system, sandwich composite insulation system and external wall's external insulation system, and reveals that the external wall's external insulation system has the advantage of strong feasibility, law cost, effective heat insulation break bridge and protective structure, which offers great potential for existing buildings in energy-saving rebuilding, thus finding a widest application and enjoying a promising market prospects.

Abstract: Green building is rapidly transforming the design and construction industry around the globe. Simultaneously, a growing numbers of industry practitioners are taking the advantages of building information modeling (BIM) to upgrade the sustainable performance of green building. BIM tools encourage an integrated lifecycle green building management from design, construction, and prefabrication to operation and maintenance. This paper represents using BIM technology to achieve green building objectives and sustainable performances.

Abstract: Energy-efficient problems for houses need to be solved, with poorly insulated housing used in northwest rural area of China requiring large amounts of energy for house warming. The application of straw bale houses in domestic and overseas indicates straw bale houses’ benefits. This article compares straw bale houses with traditional structures and analyzes the advantages and disadvantages of straw bale houses, also points out the feasibility and prospects of the utilization of straw bale houses in northwest rural area.

Abstract: Shortage of green skills has become a major constraint to energy efficient building programs and policies of Malaysia and many Asian countries. Yet, studies aimed at green skills are rare. Relying on an online survey of 99 professionals accredited by the Malaysian Green Building Index (GBI) this study seeks to: [1] identify the necessary green skills required for design and delivery of energy efficient building; and [2] identify and capture areas of skill gaps based on available and future green skills needs. Our preliminary result reveals that generally, available energy efficient green skills in Malaysia are below average. The highest skill gaps were found to be in the areas of energy efficiency maintenance for HVAC system, competence in use of diagnostic tools to measure building energy efficiency, carbon storage and capture in buildings and competency of architects/ builders in passive designs and installation.
