Abstract: The Solar Energy Utilization Performance indices for small-scale solar heating buildings are the research object. Based on1042 meteorological data measurements of solar irradiance and outdoor air temperature from 1988 to 2017 to establish the relationships between the solar heating fraction（SHF）and solar heat load ratio（SLR）,which meet energy-efficiency design standards for residential buildings. In addition,the calculated monthly total heat gain through the glass of a typical city in China was obtained,which provided a simplified calculation for the SLR. This study simplifies determining the level of solar heating available in buildings at the beginning of the design plan. It provides essential support for implementing of the carbon-neutral strategy by integrated building design.
