“…As a result, the near-surface atmospheric O 3 concentrations and the number of days exceeding the standard have shown a significant upward trend in the past three years (Cheng et al, 2017;Zhang and Zhang, 2019). Therefore, factors of influencing O 3 formation and spatiotemporal distribution of O 3 concentration need to be better understood to take measures for O 3 control (Cheng et al, 2018;Yang et al, 2020;Zhao et al, 2020). However, the spatiotemporal dynamics and influencing factors of near-surface O 3 concentration in Beijing are not clear.…”

“…The tapered element oscillating microbalance or b-absorption methods were used to measure PM 2.5 concentration, and UV-spectrophotometry was used to measure O 3 concentration. Air quality measurements, data quality control procedures, uncertainties, and accuracies are described in the China Environmental Protection Standards such as " HJ 193-2013" and"HJ 655-2013" (Ministry of Environmental Protection (MEP) of the People's Republic of China, 2013aChina, , 2013b and the Chinese National Standard HJ/T 193e2005 (Xie et al, 2016;Zhang & Cao, 2015;Zhao et al, 2020 FNL grid. The near-surface meteorological variables in FNL are further bias-corrected based on the collected near-surface observations.…”

“…The constraint of energy usage intensity is that it does not consider elements that include energy utilization for HVAC and lightings' systems efficiency individually [6]. Energy endorsement is used as an auxiliary to regulate energy usage intensity to measure the energy performance of HVAC and lightings' system with various operational conditions and operational modes [7]. Energy endorsement models are depleted for a long time in order to calculate and control buildings' energy performance in different climatic conditions.…”

“…Smart buildings application delivers a possibility of minimizing the electrical energy in a way that it will direct to substantial reduction in CO 2 emissions. The environmental evaluation of the proposed control system depends on the avoided amount of CO 2 emissions caused by electricity savings which can be expressed using (7). [21]- [23].…”
