A passive performance prediction model is also proposed considering multi-dimensional variables including location, climate change, building design, and operating characteristics (Wang et al. 2022b) . Ventilation is an effective solution to remove air pollution in the built environment. The urban population and motor vehicles bring in an increasing number of viaducts. The effect of the viaduct geometry and ambient wind speed on the flow field and diffusion of reactive pollutants in a street canyon is studied using CFD simulations (Ming et al. 2022 ). Moreover, a novel high-order Markov chain model is developed to predict indoor particle dispersion and deposition under fixed and dynamic ventilation modes (Mei et al. 2022 ). In addition, the issues of Re-independence of indoor airflow and pollutant dispersion within an isolated building are investigated (Cui et al. 2022) . Furthermore, the ventilation system in an LNG cargo tank construction platform is numerically evaluated considering the impact of supply vane angles and return vent configurations, and the optimal allocations are identified by a novel analytic hierarchy process-entropy weight evaluation method (Shi et al. 2022) . Heating is one of the key issues for environmental control. It is addressed by 3 papers in this collection. Two novel radiant floor heating systems which are based on micro heat pipe array (MHPA) with different floor constructions are proposed and evaluated (Jing et al. 2022) . The coupling of radiation and convection has a significant impact on the thermal comfort of space heating. The thermal environment characteristics of different laying positions and sizes of radiation and convection heating terminals are investigated (Fan et al. 2022) . A comparative study is conducted on the BUILD SIMUL (2022) 15: 1175-1176 https://doi.org/10.1007/s12273-022-0893-0 E-mail: ypyuan@swjtu.edu.cn thermal comfort performance of different ventilation modes for space heating (Kong et al. 2022) . In addition, a dual-cavity window with a gravity-driven cooling system that can remove the absorbed solar heat and reduce the heat gain through the window is proposed and discussed . For the energy recovery indirect evaporative cooling system, the heat and mass transfer model is optimized considering condensation and the energy efficiency is quantified (Liu et al. 2022) . Finally, the influence of the spherical canopy on the intensity changes of thermal radiation absorbed by the adjacent wall is discussed to provide theoretical and design guidance for the selection of tree species and spatial configuration . It is our pleasure to greatly appreciate all peer reviewers for their rigorous reviews and suggestive comments, as well as all authors and co-authors for their tremendous efforts. To conclude, on behalf of ICCEBE 2021 organizers, we would like to show our gratitude to all who made ICCEBE 2021 and this topical issue possible. We especially thank the Editor-in-Chief, Professor Da Yan of Tsinghua University, and the staff of Building Simulation journal for the contribution made to the dissemination of the outcome of ICCEBE 2021 conference. ICCEBE 2023 will be hosted by Shanghai Jiao Tong University. We look forward to furthering the scientific exchange and research collaborations through a series of ICCEBE conferences.
