Abstract: Rules of thumb in daylighting have been expressed in a variety of modes in architectural. It can be divided into categories based on the parameters which constitute them. One of the categories is floor depth. This paper presents the impact of different floor depth on daylighting performance of the simulated office room using 1 meter shading device. Several parameters such as shading device, ceiling height, and material reflectance have been appointed. Overcast sky was chosen as tropical-compatible sky types. Models then were simulated and analyzed using an application of IES_VE software called RADIANCE. Existing daylighting rules of thumb has been modified and thus create new formula for Kuala Lumpur sky based on the smallest academic office room in public university.

Abstract: A solar district heating and water heating integrated system has been designed and installed in a 5000m2 residential quarter. The integrated system uses vacuum glass tube solar collector to collect solar radiation energy, and uses water as heat medium. Solar energy provides almost 50% of the total heating energy consumption in winter. The inadequate part of energy can be provided by a steam heater which steam is provided by exhaust steam of the turbine from a power station nearby. The integrated system is operating automatically according to the solar radiation and working condition. Low-temperature floor radiation system is used as indoor heat radiator. At the same time, the system can provide 24h hot water supply. The integrated system has operated for 3 years, saves a large amount of energy, and receives good profit in both economical and environment.

Abstract: This study is to achieve a better understanding of the microclimate with architectural component which enhances indoor environment of school buildings. Sophisticated use of transitional space characterized by retractable canopy can affect environmental conditions in ways which lead to have the potential to reduce the energy demand of the buildings in the UK. Computer simulations is adopted to compare heating energy demand in different cities (London, Manchester and Glasgow) with 0%, 50% and 90% transparency of canopies for the fixed type. Result shows flexible type of canopy performs better in terms of indoor energy demand for heating than that of using fixed type of canopy.

Abstract: Life Cycle Cost (LCC) theory and method have a very positive influence on popularizing energy-saving of green buildings technology and reducing buildings energy consumption. However, applying LCC method into the construction industry field must be based on adequate and accurate data. In establishing the cost database of building LCC, America walks in the forefront of the world. Although China's building LCC cost database has been rapidly developed in the past few years, there is still a large gap between China and the United States. By comparing and analysing the establishment of building LCC cost database of the two countries-United States and China, this article indicates the key issues should be solved to build and further improve the Chinese future building LCC cost database, as well as give some relevant advice.

Abstract: Life Cycle Cost (LCC) method can not only help users make economic decisions on a construction project, but also have a positive effect on popularizing building energy-saving technologies and reducing building energy consumption. However, LCC has not received due attention in China. This paper analyzes the main obstacles to popularizing LCC in China and explores the solving strategies of promoting LCC in China by means of the functional process theoretical model.

Abstract: In this study intends to provide a base document on the energy consumption pattern of elementary school buildings in South Korea by analyzing the fluctuation of power consumption in the classrooms, which occupy the largest floor space in any school building.

Abstract: In this study investigates the energy consumption patterns and building facilities of rental houses for the low-income class in South Korea, and presents the results as base materials that will be needed to realize energy welfare in the country.

Abstract: This paper presents an idea on generating green energy by extracting discharged wind energy from a cooling tower. Two vertical axis wind turbines (VAWTs) integrated with a wind power-augmentation device are installed above a cooling tower to harness unnatural wind for electricity generation. The wind power-augmentation device is built with several guide-vanes and diffuser-plates to improve the performance of the VAWTs. Guide-vanes are designed to create a venturi effect and guide the on-coming wind stream to an optimum flow angle which is matched to the optimum angle of attack of the VAWTs. Diffuser-plates are tilted at an optimum angle to draw more wind and accelerate the discharged airflow. From the laboratory test, the VAWTs performance was increased by 7 – 8 % when guide-vanes and diffuser-plates are installed at their optimum angle. The correct matching of VAWTs for this system is expected to generate electricity at their rated power constantly when the cooling tower is in operation. This system can contribute to the reduction of greenhouse gases emission and conservation of the environment for a healthier life since fossil fuel consumption for energy generation is reduced as well as efficient use of energy.

Abstract: In this study, the green animal-based, which has been prepared by prolonged boiling of the inedible connective tissues of domesticated ungulates, was investigated for adhesive properties. The viscosity of green animal-based wood adhesive was measured and compared with that of urea-formaldehyde (UF) and phenol-formaldehyde (PF) which are widely used synthetic glues in the wood industry. Also, the crude protein, crude fat, crude fiber, nitrogen free extract (NFE) that represents carbohydrate, and ash as the organic components of green animal-based glue was measured. According to the results, the green animal-based wood glue was found suitable to be used in wood industry.

Abstract: Using salvages and reused materials is an effort to conserve energy and other resources, and reduce greenhouse gas emissions; on the other hand, these materials cost a fraction of the price of new. The information generated by this study revealed several useful material management guidelines. Statistical results shows that designers who are educated about these products and how they can be used, are interested in using recycled materials, and can potentially decrease the amount of trash being produced on a much larger level. All information was obtained from product brochures, manufacturer websites, visiting construction sites, statistical analysis and conversations with designers.
