Design Optimization Approach for Residential Outdoor Environments Based on Seasonal Variations in Local Thermal Perception

Buildings, Journal Year: 2025, Volume and Issue: 15(6), P. 876 - 876

Published: March 12, 2025

Outdoor thermal environments significantly influence residents’ outdoor activities, yet current urban design often lacks sufficient attention to comfort, and existing methods remain inadequate. This study addresses these gaps by first demonstrating the crucial impact of on human activity through a combination field measurements resident surveys. Using Yangtze River Delta region as case study, we propose set optimization strategies based local perception characteristics. By conducting quantitative analysis perception, this identifies their seasonal comfort needs translates insights into refined space strategies. The results highlight significant variations in preferences, with autumn providing highest satisfaction, followed winter summer. Based findings, precision-driven optimizations that align spatial configurations thresholds. Strategies such dynamic shading arrangements for summer cooling wind-shielding structures warmth were tailored actual usage patterns, enhancing functionality livability spaces. research offers data-driven approach climate-responsive human-centered residential design, valuable guidance planners designers.

Differences Research on Human Overall Comfort Under Low Pressure

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(7), P. 3815 - 3815

Published: March 31, 2025

A low-pressure environment can significantly affect human physiological mechanisms. It causes differences in overall comfort evaluation at different pressures. Current research mainly focuses on the impact of single environmental factors under low pressure. However, studies considering multiple are lacking. This paper was based effective-function method. Thermal, luminous, and acoustic experimental were carried out standard atmospheric pressure In this study, we conducted an in-depth exploration The key findings as follows: (1) There (2) influence order unit changes determined. Within zone, variations 1 °C, 100 lx, 5 dB caused similar evaluation. When a factor deviated from it became dominant affecting POCV (Predicted Overall Comfort Vote). (3) peak zone pressure, energy-saving needs, slightly cooler winter warmer summer chosen. And illuminance shifted to left x-coordinate. tolerable smaller, easier reach lower limit. (4) nomograms for common working condition parameters drawn. Through parameter interaction, “superior” used compensate “inferior” ones, thereby improving Based these findings, provides theoretical basis data support design aerospace high-altitude environments. offers beneficial references ideas integrated development interdisciplinary fields.

The effects of acoustic-light-thermal environment quality parameters on pedestrians’ overall comforts in residential districts

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 23, 2024

This study explored subjective responses towards various environmental quality parameters. It would be helpful to approach an overall comfort improvement relating physics. In order investigate the combined effects of sound, light and heat on pedestrians, which could evaluated by vote, two residential areas in Yubei District, Chongqing (a Cfa city China) were selected for field measurements questionnaires. Three three key findings concluded based parameters via multiple linear regression. First, average outdoor neutral temperature, mean sound level illumination intensity determined 26.6 °C (determined physiologically equivalent temperature), 56.5 dBA A-weighted continuous level) 21.4 klx LUX), respectively. Second, considering both physiology psychology, thermal perceptions varied acoustic environments. Residents partially had lower temperatures at noisy condition. Third, factors a significant effect comfort. Positive correlation between temperature vote was found (sig < 0.000); while pressure not always significant. Hence, stress played role people's has environment human perceptions. provided better understanding against dwellers' feelings under complex circumstances. Future urban design planning works should consider cooling regarding contextual acoustical visual

Assessing the impact of mega-city construction engineering on urban livability: an explorative study of Yan'an

Frontiers in Public Health, Journal Year: 2024, Volume and Issue: 12

Published: May 15, 2024

Yan'an City is a typical squeezed city in China and faces the challenge of limited living space. The adoption “Mountain Excavation Construction (MECC)” program was poised to elevate city's livability. Despite importance megacity construction projects, few studies have examined their impact on urban This study aims fill this gap by analyzing effects MECC satisfaction characteristics livability City, based survey data from both old new areas. Employing factor analysis multiple linear regression, paper assesses influence across different demographic groups, including age, educational background, occupation. empirical findings demonstrate significant positive effect project However, during categorization discussions, some respondents expressed concerns about its negative impact. results regression indicate that factors such as career prospects, residential satisfaction, interpersonal relationships, transportation level significantly (R2 = 0.607 ND R 2 0.609 OD).
