Abstract: This study reviews some published literatures to seek the relationship between the parameters of indoor environments and the energy consumption. The indoor thermal environments are categorized and defined as different indices and variables. The building energy can be determined by indoor air temperature, occupant-area ratio and working days. Several parameters of indoor thermal environments such as air velocity, neutral temperature, predicted mean vote, indoor air quality, and set point temperature, are summarized for their influence on the energy consumption. It can be concluded that the increased local air velocity, enhanced neutral temperature, and enlarged set point temperature may be beneficial to reduce the energy consumption.

Abstract: In the recent twenty years, with the rapid development of china’s economy and city construction, residential projects development becomes more prosperous than ever before. The speed of Chinese Chongqing residential projects development is higher than any period in history. It brings many problems, such as house price went up too quickly, resources consumed over much and so on, due to the development speed was too high and the developers seeking high profit unilaterally. Therefore, we must seek a proper balance between endless requirements and limited resources supply and aim at to construct a keep zoology balance, increase the efficiency of energy and other resource, and share comfortable healthy and most cost-efficient residence as a final goal. Based on previous reasons, the thesis try to provide a basic point for the whole industry to correspond via the evaluation and research on durative of Chongqing residential project, to guide developers to follow a uniform high standard while developing residential projects, heighten the integral level of residence development.

Abstract: Urumqi locates in Xinjiang province, which belongs to cold climate zone in China, the local heating period during the winter up to 6 months. The local solar energy is abundant; up to 130-140 Kcal/cm2·Y that can provides advantage condition for utilization of solar energy. Floor radiant heating system requires lower supply temperature compared with the traditional heating system, which provides an advantage condition for using solar energy as heat source since it is already widely used in Urumqi. Based on these, the study established a solar energy floor heating system in XinJiang University. The system’s components, operating principle and indoor air temperature profile had been introduced in this paper. Through the experimental study the research results shows that 40% time of winter period in cold climate zone, the solar energy floor system can working well without any auxiliary heat source, the heat generate from solar collect system can satisfied the indoor heating requirement. The application of this system can make energy saving and environmental protection become true.

Abstract: This paper introduces the adjustment curve equations of district heating system commonly used in secondary network. On this basis, adjustment curve equations of the adjustment that combines quantity adjustment and quality adjustment are proposed. Then taken a community in Zhangjiakou as an example, we compare the power consumption of the adjustment scheme proposed in the paper with that of quality adjustment and quality adjustment with different quantitative ratio in each period. The analysis shows that the adjustment scheme has much more potential in energy-saving.

Abstract: The green building design of Huizhou traditional dwellings isn’t the same as their external shape being dominant character, but being implicit among building itself, environment and building fabric of enclosure structures. The article analyses excellent ecological design of Huizhou traditional dwellings from three different aspects, settlement’s interior ecological environment, external ecological environment and building fabric gene of rounding to protect structure. At last, it expects to distill all of them and plant into modern architecture in order to explore a road of innovation suitable modern design for Huizhou residential district.

Abstract: In the construction of new socialist countryside strategic decision background, in view of China's energy shortage and the present situation of the huge energy consumption, and puts forward the development through solar house to solve the problem of heating in northern rural residents, at the same time, reduce energy consumption level and Improve construction of solar and other renewable energy sources. Combined with the characteristics of the northern countryside, from construction design principle, energy-saving design, construction of building plane made profile design introduced the rural north solar house construction optimization design ideas and points. In liaoning province for ecological rural construction laid solid foundation, and for solar house in north China rural development provides a certain basis.

Abstract: China's rural residential energy consumption increase constantly, and explore practical rural residential solar energy application technology, solve the energy problem of heating in winter, improve the living standards of the people, and improve the quality of life, to accelerate the pace of China's overall energy conservation of the building is of vital importance. Through investigation method, the cold areas of the present situation, the rural housing live characteristics, the peasant's living standard, the solar energy application investigated. The sun room types, characteristics, collection hot parts design points are analyzed. At present, the passive solar houses, because of its simple structure, low cost, is suitable for application in rural areas, the highly development prospects.

Abstract: Base on theory, experiment system was established to research the feasibility of using solar energy to heating in freezing region. Through one heating period to verify that solar assistant floor radiant heating was feasible and it can save energy, initial cost can be payback in 4 years.

Abstract: A constructed wetland-pond system consisting of a subsurface-flow (SSF) wetland, and a scenic pond in series was used for reclamation of septic tank effluent from a campus building. The results show that SSF wetlands effectively removed major pollutants under a hydraulic loading rate between 3.6 and 7.1 cm/d, with average efficiencies ranging from 85% to 86% for TSS, and 71% to 84% for BOD5. There were a variety of ornamental plants and aquatic animals established in the scenic pond with good water quality, thus enhancing landscape and ecology amenity in campuses.

Abstract: Renewable energy construction project can promote the sustainable development. The life cycle list of the air conditioning system of a renewable energy construction project has been established. Calculate this project’s energy consumption and emissions at construction stage and operation stage. The emissions include CO₂、SO₂、NOx、CO、CH₄、PM、NMVOC and NO2. This project in the whole construction stage of the energy consumption is 17861224.1 MJ, accounting for 23% of the total life cycle energy consumption.
