Special Issue Information

Dear Colleagues,

Indoor air quality and thermal comfort significantly affect the wellbeing of indoor occupants; however, creating healthy and comfortable indoor environments consumes a large proportion of building energy. New developments in indoor comfort and health are emerging, such as the following: non-uniform thermal environments, personalized thermal comfort, thermal adaptations, interactions of thermal comfort with other comfort domains, AI-powered thermal comfort models, intelligent algorithm-based control methods, advanced air distribution, graded ventilation, interactive cascaded ventilation, vortex ring ventilation, intermittent demand-controlled ventilation, and airborne infection risk control. These advanced developments not only contribute to occupants’ satisfaction and health but also save energy, a prospect that is of particular interest in this Special Issue. Relevant topics covered by this Special Issue include, but are not limited to, the following subjects:

  • Thermal comfort;
  • Indoor air quality;
  • Airborne infection risk control;
  • Advanced air distribution;
  • Building ventilation;
  • Radiant cooling;
  • Radiant heating.

Air conditioning is the most common and efficient measure against summer heat. However, overcooling issues exist widely in well-conditioned buildings, and the health risks and causes require further exploration. This study aims to rethink the indoor environment control and demand in hot summer from a novel perspective of yin summer-heat in traditional Chinese medicine. The core idea was to reflect health risks embodied in the indoor environment control that was oriented by the average comfort zone in air-conditioned buildings. Three research questions were explored, namely, indoor–outdoor environment features in hot summer, the heterogeneity of demands and behaviors, and relationships between personal attributes and lifestyles. Eleven field tests were conducted in residential buildings, together with experiments in an office building and three questionnaire surveys with 765 responses from 2020 to 2023 in China. Results showed that notable indoor–outdoor environment gaps appeared due to air conditioning. Yin summer-heat symptoms, such as a heavy feeling in the body, were reported by individuals of vulnerable constitutions even in neutral air-conditioned environments. In addition, Chinese medicine theories, including pathogenic factors, constitutions, and health preservation principles, worked well to interpret diverse environment perceptions, demands, and adaptive behaviors. These findings will add to the scientific basis of wellbeing in indoor environments. Full article

Buildings are major contributors to carbon emissions, emphasizing the need for energy efficiency. However, existing solar-integrated building façades often face integration and adaptability challenges. The aim of this study is to propose and evaluate an innovative building-integrated heat pipe-embedded (BiHPe) prefabricated wall panel for sustainable building design. By embedding heat pipes into concrete walls, the system transfers solar energy to domestic water. The performance of the system is evaluated using a comprehensive approach that integrates dynamic modeling, experimental validation, parametric analysis, and a case study. A dynamic energy balance model was developed and experimentally validated, identifying key factors affecting system performance, such as heat pipe spacing, absorber material, and heat pipe placement and configuration. Parametric analysis was conducted to assess the impact of these variables. Simulation results from a case study in Hong Kong show that the system reduces wall heat transmission to 76.1%, achieves a water gain efficiency of 16.7%, and saves 162 kWh/m2 of electricity annually. Additionally, the system stabilizes indoor temperatures, improving thermal comfort. The BiHPe panel offers a multifunctional solution that combines energy efficiency, thermal comfort, and water heating, demonstrating exceptional adaptability and performance in cooling-dominant zones, making it a promising option for sustainable building design.
