The energy consumption of per unit area in public building are larger than the residential building in China, and the energy-saving reconstruction for existing public building is less than the residential building at present, so it also have great potential and space of energy conservation. This paper based on the feature of climate and energy consumption of existing public building, formulated the evaluation principle of energy-saving reconstruction technology, put forward from economy, energy-saving effectiveness, advance and combination property of technology to determine the design method to energy-saving reconstruction, to select appropriate technology. At last, this paper through a case building---a teaching building in Xi'an to analysis how from specific problems to apply appropriate technologies in northern area.

Building engineering in China is divided into civil building and industry building. Civil building engineering includes residential building and public building. There are many types of public building: shopping malls, office buildings, hotels and so on. In this thesis, architecture test and investigation are processed for the large public building such as hotel type, which focus on its characteristic features of energy consumption. Then energy conservation schemes are propounded and applied in real buildings.

The continuing importance of energy conservation in the building sector has drawn major attention to energy audits of existing buildings in different climates. In this paper, the energy conservation potential of a residential building located in Iran’s cold climate was investigated through an analysis of its actual energy consumption and through computer simulation. The building base-load was determined using a linear regression method based on existing energy bills, and was used to validate the computer simulation of its energy usage. The impact of typical energy saving solutions was evaluated for three cost refurbishment scenarios: low, medium and high. The results show that the existing construction and envelope materials fail to meet the national standards of Iran, but insulating the envelope was found to be a more cost-effective measure than modifying the windows. The results also demonstrate that although the use of energy-saving solutions has a significant impact on energy consumption, even the most economic solutions investigated will have a payback period longer than one decade. Thus, with current energy prices the reviewed energy conservation strategies are not economically justified in Iran from the consumer perspective, as investment in the methods considered typical in other parts of the world will not show a return for at least a half-century.

Aim at the current situation of high energy-consumption of the large public building,proposed a WebAccess–based energy-consumption management and energy-saving analysis system.And it be used Zigbee distributed energy consumption measurement net for data remote transmission. The status of energy consumption in the future can be predicted through energy-consumption databases and energy-consumption models were built. The system can real time monitor and manage the energy-consumption status in large public constructions. It can provide a favorable foundation not only for energy conservation and reformation of those completed large public building, but also for energy conserved operation and supervision of those new constructions. This can help to achieve the goal of energy conservation and energy-consumption reduction in large public building.

At present, people pay more attention to the energy consumption of building electrical design, the use of energy-saving design can maximize the energy conservation resources, and ultimately increase the pace of social sustainable development. Therefore, the energy-saving designers involved in the need to follow the economic rational, safe and feasible benchmark to select the appropriate energy-saving measures to increase research and development of new technologies, new products and new energy, the concept of sustainable development to be implemented. In view of this, this paper mainly analyzes the energy saving technical measures in the electrical design of thebuilding.

High energy consumption is an important issue affecting the operation and development of wastewater treatment plants (WWTPs). This paper seeks energy-saving opportunities from three aspects: energy application, process optimization, and performance evaluation. Moreover, effective energy-saving can be achieved from the perspective of energy supply and recovery by using green energy technologies, including wastewater and sludge energy recovery technologies. System optimization and control is used to reduce unnecessary energy consumption in operation. Reasonable indexes and methods can help researchers evaluate the application value of energy-saving technology. Some demonstration WWTPs even can achieve energy self-sufficiency by using these energy conservation technologies. Besides, this paper introduces the challenges faced by the wastewater treatment industry and some emerging energy-saving technologies. The work can give engineers some suggestions about reducing energy consumption from comprehensive perspectives.

An energy saving residential building in Zhangjiakou was took as research object, which was designed and constructed according to the criterion of 65% energy saving of the third stage, utilizing simulation software Dest, which was developed by Qinghua University, energy consumption simulation and economic analysis were done to the building. The results show that compared with the former residence which was built according to the non-energy saving design, the implementation of new design standard for building energy saving can not only achieve better energy saving effect, but also its payback period is short, so the new design standard for building energy saving is worth spreading.
