Summary: A naturally-ventilated operational classroom was monitored to assess the spatial variations of classroom air pollution, thermal comfort, and ventilation indicators under different scenarios. The study found that CO2 and PM10 concentrations varied over time rather than space. Two air purifiers were most effective when placed in the most polluted area of the classroom. This study provides high-resolution data for validating detailed numerical models and informing decision-making to reduce children's exposure to air pollution and re-breathed CO2.

Summary: Due to high costs, cooling installations are rarely used in residential buildings in heating-dominated climates like Poland. This study attempts to assess indoor operative temperature during summer and propose ways to reduce overheating using the thermal network model of a naturally ventilated single-family residential building located in central Poland. The findings suggest that using external shading on windows is the most efficient solution for controlling indoor comfort in residential buildings without a cooling system.

Summary: Since the early 2000's, there has been a significant focus on human thermal assessment in urban outdoor environments. However, the absence of an agreed protocol for outdoor bio-meteorological research has resulted in complexity when comparing study results. This complexity arises from the variety of thermal indices, interpretations of bio-meteorological terms, data collection procedures, and methods for determining thermal comfort ranges. This study aims to review strategies and methods for human bio-meteorological research and suggests a framework for future research to ensure accurate assessment of thermal perception.

Summary: This study examined the use of expanded metal meshes (EMMs) in horizontal shading devices. Simulations and experiments were conducted with EMMs of varying opening ratios and directions. Data on air temperature, surface temperature, and black globe temperature were collected from different experimental and control groups. Simulation results using Grasshopper were used to analyze long-term climate conditions and provide customized suggestions for users in Tainan. The findings can serve as a benchmark for parametric design analysis of EMMs and be applied in the design phase of outdoor horizontal shading devices. It was found that EMMs with small openings provided effective shading effects throughout the day. North-facing EMMs are recommended in the Tainan area, as they blocked 70% of sunshine in our simulations. West-facing EMMs are suitable for morning shading, blocking 50-90% of sunshine. East-facing EMMs can block 50-90% of sunshine after noon, making them ideal for recreational areas in the afternoon and evening. South-facing EMMs are not advised in Taiwan due to their suboptimal shading performance in the morning and afternoon.
