The invention relates to the technical field of energy-saving effect evaluation of buildings. The method provided by the invention comprises the following steps of: A determining a building energy consumption calculation model; B, optimizing the building energy consumption calculation model; C, acquiring and drawing a correlation curve of influence of a building envelop structure on building energy consumption, and measuring corresponding weight coefficient; D, obtaining a building energy consumption calculation equation; E, inputting the building envelop structure information into a building energy consumption calculation module; F, obtaining building energy consumption evaluation. Compared with workload of at least ten days of the conventional energy consumption calculation, workload of the method provided by the invention is reduced to about one day for only executing acquisition of building basic information input, calculation of the energy consumption calculation module and outputting of result, thus, problems of the prior art, such as high cost, long cycle and failure in meeting needs of project application, are solved, and the method can be generalized and used in practical guiding for projects.

Description

technical field [0001] The invention relates to the technical field of building energy-saving effect evaluation, in particular to a simple method for evaluating the energy-saving effect of residential buildings based on statistics. Background technique [0002] There are many factors that affect building energy consumption. Differences in climate conditions in different regions, differences in the living standards and energy consumption patterns of users in buildings, and changes in the thermal performance of building envelopes will all lead to changes in building energy consumption. It is difficult to objectively reflect the level of building energy consumption and truly evaluate the effectiveness of building energy-saving technologies. [0003] At present, the methods for evaluating the energy-saving effect of buildings mainly adopt the trade-off calculation method based on energy-saving design standards. That is, in accordance with the requirements of energy-saving desig...

Problems solved by technology

For example, "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Cold Winter Areas" JGJ134-2001 stipulates that the energy consumption limit for heating and cooling for residents is 55.1kWh / m 2 , in fact, according to the energy consumption statistics of residential buildings in Shanghai, the heating and cooling energy consumption of residents is only 10kWh / m 2 It can be seen that the results of the trade-off calculation method are very different from the actual energy consumption; 2) The trade-off calculation method is highly specialized and not convenient for engineering applications

Since the existing energy consumption simulation software is relatively professional, it is possible to draw a relatively reasonable evaluation conclusion only by personnel with corresponding professional background and rich engineering experience, resulting in high application cost and long cycle, which cannot meet the simple and fast engineering requirements. need
