Research On The Energy-saving Of Multi-story Residencial Buildings In The Northern City, Zhang Jiakou Of Hebei

With the developing of economy, the growth of population and the improvement of our living standard, our demand for energy is increasing. However, just like other countries in the w orld, w e a re facing w ith e nergy crisis. In addition, t he w aste o f e nergy h as b rought about environmental pollution and poor air condition. As the main energy consuming family, architecture has been emphasized by many countries in terms of energy-saving and as a result, the corresponding measures have been put forward.We have made some achievements in architectural energy-saving. For example, a series of energy-saving criteria and statutes have been laid down and published, some computer analogue software have been developed, and there are also some achievements in terms of building materials and techniques. Nevertheless, compared with foreign architectural energy-saving measures, there are still some problems in ours, such as the lack of research on regional and local condition.Zhang Jiakou is a border city in the north of North China, which is located in the juncture of bitter cold areas and cold areas. Because of its backward economy, people have less conscious of saving energy in building, and energy-saving systems and statutes are not amplified too. Although <> (JGJ26-95) has been issued for many years, and there are some effects in terms of energy-saving of Zhang Jiakou residential building, there is still a big gap between the design and construction of this area and the given standard, In the process of designing, an energy-saving design file needs filling in. However, there is discrepancy between actual construction and design i tself, so that local residential building consumes a lot of energy, which surpass the energy-saving standard. Accordingly, there are no suitable measures to local condition in terms of energy-saving in residential architecture.The present residential buildings of Zhang Jiakou city are all multi-story buildings. Based on the geographical position, climate features, energy structure, economic development and local customs; in the light of <> (JGJ26-95) , the thesis give an overall evolution on the residential energy consumption and thermal environment indoors of this area, analyze the problems and potential in energy-saving, put forward the necessity and urgency in saving energy, and arouse the attention of policy-makers, designers and constructors by the theoretical calculation, computer analogue, investigation and on-the-spot test.Using the techniques and experience of China and other countries for reference, the paper gives an analysis on the energy-saving of envelop such as walls, doors, windows and roof in the light of specific conditions of Zhang Jiakou city. The new energy-saving design plan that is suitable for the local residential building is put forward and analyzed from the perspective of economy. The design will make the building energy-saving of this area tally with the national and regional policies, regulations, criteria and standard with little investment, more benefits, architectural energy-saving can be achieved with respect to economy, society and environment so that the sustainable development of urban residence in this area can be realized.
