Abstract

Implementing household heat metering and charging is a significant way to realize building energy conservation in northern China, but the current heat metering has two contradictions for promotion. The first fact is the corner users have a higher heating consumption than the center users with its bigger area of external envelope, and the second is the heating costs of high-temperature users will increase sharply due to the phenomenon of adjacent room heat transfer (ARHT). This study selects a residential building in Tianjin, China as a research object, and field measurement and energy simulation are adopted to reveal every process of heat transfer including ARHT. The heating load and ARHT are further reallocated for each unit, and a new heat charging scheme is then proposed. The results provide a case study for the fair allocation of heat charging, which is vital to the implementation of household heat metering in China.
