Energy consumption meter and energy consumption evaluation method based on building area and energy efficiency ratio

Abstract

An energy consumption instrument that integrates prediction and evaluation of public building energy consumption based on building area and energy efficiency ratio, belonging to the technical field of building energy conservation The touch screen of the equipment for the output of the results is used to store the basic building parameters such as building area, area area, energy consumption data, etc., and the single-chip microcomputer system 8051 for control and calculation. The self-adaptive method enables the energy consumption meter not only to predict and evaluate the energy consumption of public buildings according to the building area, but also to optimize the energy consumption evaluation results according to the regional area, making the evaluation results of the energy consumption meter more accurate and reliable. The invention can accurately predict the energy consumption level of public buildings, and give the energy consumption level scores among multiple public buildings, which is beneficial to the development of energy-saving management and energy-saving renovation in the field of domestic public buildings.

Description

technical field [0001] The invention relates to an energy consumption meter for evaluating the energy saving of public buildings, in particular to an energy consumption meter integrating prediction and evaluation of public building energy consumption based on building area and energy efficiency ratio, and belongs to the technical field of building energy conservation. Background technique [0002] Public buildings mainly include office buildings (office buildings, government office buildings, etc.), commercial buildings (shopping malls, hotels, restaurants, etc.), science, education, cultural and health buildings, communication buildings, and transportation buildings. According to a sample survey, the area of ​​large public buildings in my country accounts for less than 4% of the urban construction area, but consumes more than 20% of the electricity. The problem of high energy consumption in large public buildings is more prominent. Strengthening the management of energy cons...

Problems solved by technology

However, although this patent considers the impact of meteorological factors and the thermal insulation of the envelope on building energy consumption, its basic principle is still based on the DeST-h energy consumption simulation software, and the DeST software is only applicable to the energy consumption of a single building. Therefore, this evaluation method cannot be applied to the horizontal comparison of the energy consumption of multiple buildings. In other words, this evaluation method is not suitable for the energy consumption evaluation of multiple existing public buildings
