Here we verify an off-line urban building energy model (CM-BEM) against ‘observed’ anthropogenic heat and electricity consumption at Tokyo (Yoyogi) residential area. Anthropogenic heat (QF) due to electricity air-conditioning (AC) use (QF, AC) is estimated by continuous simultaneous observations of atmospheric O2, CO2 and turbulent CO2 and heat fluxes. Here we explain the outline of how to estimate QF, AC. (1) The O2:CO2 exchange ratio (oxidation ratio, OR) is used for the partitioning of CO2 into emissions from gas fuels and gasoline (see detail in Ishidoya et al. 2020), which allow estimating QF from gas fuels and gasoline (QF, gas and QF, traffic), respectively. (2) Total QF is estimated by turbulent heat fluxes and net radiation observations using a heat balance equation within the constant flux layer. Finally (3) the QF, AC is estimated by ‘Total QF – (QF, gas + QF, traffic)’. This estimation allows verifying directly simulated QF, AC by the CM-BEM. Our aim is an improvement of the CM-BEM to develop more realistic QF and CO2 inventory data. Here we compare simulated QF, AC, electricity consumption, and turbulent heat fluxes against observations during winter (Jan-Feb 2017) and summer (July-Aug 2018) seasons at Tokyo. Our results will be reported at the conference.
