Abstract: The numerical simulation method is employed in this paper to study the indoor thermal performance of an existent passive solar house, south internal wall of which is equipped with water thermal storage tanks. The actual measured meteorological data of 2010 in Tianjin is applied in this study to obtain the hourly indoor temperature, and the indoor condition is assessed by the adaptive thermal comfort model. The results indicate that, cooling measures are not required during the summer in Tianjin weather condition when the water thermal storage wall is used combined with natural ventilation technology, thermal storage effect of the wall can reduce the indoor maximum temperature of 4 °C while increase the minimum temperature of 3°C, and make regulation of the heating system simple and feasible in the winter.

Abstract: In order to explore the application methods and development potential of solar energy technology in facility agriculture, and to seek a solution to resolve problems existing in greenhouse production, such as high heating cost and serious environment pollution etc. , an experimental study was carried out on a solar energy combined coal-fired boiler heating system used for greenhouse. In this paper, with Kunming Trifecta Orchid Nursery Co. Ltd of Yunnan Flower Demonstration Garden for experimental research object, the general design and operation method for the system were introduced, and an experiment on operation performance and heating effect of the system was tested in Kunming. The results showed that whether it was sunny or cloudy, the system could make full use of solar energy, make the water temperature of heat preservation tank reach a certain expectation, and ensure the temperature requirements on different growing stages of phalaenopsis in greenhouse. So a theoretical basis is provided for the study on solar energy combined with coal-fired boiler heating system for greenhouse. Through economic analysis of the system, the results showed that this system had high economic value, energy saving and environmental protection performance.

Abstract: With a detailed case study building information, this paper introduced the interlocking four principles for high performance building energy design within the integrated design framework. The principles and case study provided designers guidance and an example for energy efficient building design.

Abstract: With the further promotion to the energy conservation of buildings, the standard of 65 percent energy efficiency is gradually popularized. Because of some existing problems in external insulation Technology, such as security, durability and seepage, Self-insulation technique has been more and more concerned. In this paper, a kind of external insulation scheme and three kinds of Self-insulation schemes are designed for a typical residential building in Wuxi region. These schemes are simulated for energy consumption calculation and Economic Analysis by BECS software. The results show that self-insulation schemes not only meet the standard of 65 Percent Energy Efficiency, but also have more economic benefits than external insulation schemes.

Abstract: The global integration process accelerated the traditional architectural style of the same tendency in China. New building materials, such as concrete, steel and glass are used, the regional architecture that suitable environment and climate characteristics were rebuilt or demolished. The energy saving mechanism and the indoor thermal and humidity environment has undergone tremendous changes, thus to some extent affected the people's way of life and life experience. Regional architecture in Henan is also faced with the same problem. Regional architecture energy saving based on the profound understanding of regional environmental and climate condition, how to make full use of local technical conditions and natural factors and taking energy-saving measures, make its accord with the local history, social and cultural characteristics, the low carbon environmental protection “Regional energy-saving mechanisms” is the right way .

Abstract: This article aimed to introduce a building design method to reduce energy-consumption, improve indoor comfort. The article discussed under the climate condition of the Central Plains area in China , the coefficient ventilation effect of double-roof and atrium, lighting effect of atrium’s skylight and impounding glass-wall, and the utilization of solar PV, wind power generation, biomass power generation, ground-source heat pump, solar air heater and other applications of renewable energy in building designs.

Abstract: Abstract. In view of the status of existing buildings in northwest of Liaoning, most of which are lack of energy-saving practices and appear poor comfort, this paper starts from the energy saving concept, aims at figuring out the energy saving measures for cold regions, such as northwest of Liaoning province. The research includes analyzing energy-saving methods, steps and initiatives. Based on these, this paper also proposes specific technical practices to overcome the shortcomings of the existing buildings on energy conservation, and gives advices on how to reduce energy consumption and improve the quality of people’s living and working environment.

Abstract: Abstract: Model which depends on historical data of Jiangxi Province ，grey system and Brown nonlinearity exponential smoothing has been constructed, then the paper uses of MATLAB software integration to calculate parameters, precision testing and result graphical output process to program the forecasting model .By establishing the future energy combination forecasting model of Jiangxi province with the standard deviation method, it can predict the energy gap of Jiangxi Province in following 12 year. The result shows that the whole energy gap will reach 561.206 million tons tce in 2009-2020.

Abstract: Aiming at the problem of too much energy consumption of existing residential buildings in south of Jiangsu Province. In this paper，rebuilding technologies of energy efficiency for the buildings is proposed in detail, which including possible energy-saving measures for exterior walls, roofs, exterior windows, shadings and corridor in the existing buildings. An energy-saving reconstruction project example located in Hohai Xincun in Changzhou Xinbei District was presented and analyzed.

Abstract: In this paper, the physical models of the porous solar wall heating system with localized underfloor air distribution (UFAD) are established. Based on Brinkman-Forchheimer Extended Darcy and energy two-equation models for saturated porous medium, the influences of the structure of underfloor space on the heat transfer and flow characteristics of the system are simulated, analyzed and compared.The results show that the underfloor space with rational partition is good for improving the heat transfer and flow characteristics of system, and maintaining the cable system in the underfloor space.
