Abstract

The invention aims at providing an energy-saving transformation energy-saving amount checking and ratifying method based on standard effect judgment, and the purpose of energy-saving transformation energy-saving effect analysis evaluation is achieved. According to the technical scheme, The energy-saving transformation energy-saving amount checking and ratifying method based on the standard effect judgment comprises the steps that judgment is conducted on actual performance change before and after the transformation of a transformed object, based on the performance change, energy-saving amount is calculated due to standard state uniformly, and therefore system transformation energy-saving effect is obtained in the rated working state. By means of the technical scheme, the energy-saving effect generated by energy-saving transformation can be reflected objectively, the quality of engineering transformation and the effect of technical implementation are convenient to judge, and the method is suitable for applying to the effect judgment of technical popularization and technical demonstration. In the whole technical implementation process, the constraints and defects of a measuring method, a bill analytic method and a calibration simulation method are avoided, and the method is simple and easy to operate.

Description

technical field [0001] The invention relates to the field of building energy-saving renovation, in particular to identification of energy-saving energy from energy-saving renovation. [0002] The invention relates to the technical field of energy-saving identification for energy-saving renovation of existing buildings. Background technique [0003] With the rapid development of the national economy, my country's total energy consumption continues to grow, and building energy consumption and its proportion will continue to increase, especially public buildings. At present, the total amount of public buildings in my country is about 5.3 billion m 2 , accounting for 36% of the total urban buildings, and with the rapid development of urban construction, the proportion of large public buildings with high energy consumption in public buildings is increasing rapidly, and their energy consumption will also increase rapidly. Energy-saving transformation, thereby reducing building en...
