Existing school energy consumption diagnosis and low carbon transformation strategy of Tianjin Yaohua High school

Abstract

As an important part of public buildings, the school’s energy consumption and carbon emissions have received widespread attention. Relying on the existing building energy conservation situation and the energy consumption of Tianjin Yaohua High school, this paper puts forward the existing problems and energy saving space of high school. Based on the goal of low-carbon transformation, the roof and other utilizable conditions were analyzed, the transformation scheme of low-carbon energy system was brought forward, which realizes clean heating, electric energy replacement and domestic hot water supply with PVT coupling with heat pump. According to calculation, it can realize 70% replacement of school electricity, 100% clean heating and 100% consumption of renewable energy. Based on economic analysis, it has strong feasibility, which provides a reference for the subsequent low-carbon transformation of existing high school.
