Problems solved by technology

At the same time, the design of the actual building is different and the quality of the indoor environment is different. A single energy consumption per unit area cannot be directly used to evaluate the characteristics of the building operation, and it is difficult to help point out the problems of the indoor environment quality in the actual operation of the building.

Embodiment Construction

[0058] Taking building y and building z as examples, both consist of a room of 100 square meters.

[0059] 1. The system collects indoor environmental parameters and operating energy consumption data of all rooms in the building every 10 minutes. The indoor environmental parameters include temperature, relative humidity, illuminance, CO 2 Concentration, PM 2.5 Concentration and A sound pressure level. Operating energy consumption includes air conditioning energy consumption and indoor lighting energy consumption.

[0060] 2. Set the classification standard of indoor environment parameters. The details are shown in the following table:

[0061] Table 1. Classification criteria for preset indoor environment parameters

[0062]

[0063]

[0064] 3. Taking summer as an example, calculate the graded distribution of indoor environmental parameters of typical rooms in building y and building z according to formula (1).

[0065]

[0066] where q i,j is the parameter i, ...

Abstract

A building performance evaluation method comprises the steps of collecting indoor environment parameters and energy consumption data in a typical space in a building in real time, and grading different indoor environment parameters; calculating the comprehensive score of the indoor environment quality; performing weighted calculation to obtain an indoor environment quality comprehensive score of the building level; calculating an indoor environment quality comprehensive score of the annual building level; and performing correction and calculation of the energy efficiency coefficient. The problems that quantitative comprehensive evaluation of indoor environment quality is difficult to achieve, and existing unit area energy consumption data cannot identify insufficient actual operation of abuilding are solved. The functions of indoor environment parameter analysis, energy consumption analysis, intelligent early warning and the like are achieved, the building operation energy efficiencyresult can be displayed in real time, and building operation is guided to be improved.

Description

technical field [0001] The invention relates to a building performance evaluation method. Background technique [0002] With the continuous improvement of people's requirements for indoor environmental quality, large-scale public buildings in cities have continued to develop rapidly in recent years. At the same time, building energy conservation and various equipment technologies continue to advance, providing technical support for real-time building control and operation optimization. [0003] In the current building operation process, a large number of building monitoring equipment only record a single indoor environmental parameter, because there is a correlation between different indoor environmental parameters, and the indoor environmental parameters are constantly changing with time. The requirements for different indoor environmental parameters in different spaces are also different. In the past, intelligent systems only provided early warnings for extreme conditions...
