The ecological construction experience of traditional dwellings has been widely recognized. Hanzhong city belongs to the Hot Summer and Cold Winter zone, attic space is a common climate strategy in this area. research takes dwelling region as an object order analyze influence on thermal environment attic. Firstly, we adopt field investigation measurement calculate neutral temperature 13.85 °C 26.21 winter summer, respectively. It achieves First-level comfortable which ranges from 11.47 16.22 23.03 29.39 summer. Then, comparative analysis reveals that with more stable than without through simulation. indoor average operating attics 2.52 higher winter. On contrary, value decreases by 4.93 between those Finally, it shows can increase comfort duration 995 h 382 h, reduce energy consumption 1136.53kw 566.43kw Therefore, adapts local improves significantly.

Published: April 24, 2024

With the implementation of China’s rural revitalization strategy, sustainable preservation traditional dwellings has become a research priority. Moreover, with aging population in countryside increasing, limited mobility elderly may result them receiving daily corneal illuminance too low for healthy circadian stimulus. This work aims to explore relationship between and daylighting design parameters inside develop easy-to-use methods guiding indoor western Hunan. Additionally, it seeks promote digitalization informatization Hunan purposes, aiming integrate these efforts tourism community development, which supports local economy while preserving cultural heritage. The main contributions are as follows: (i) Systematic evaluation lighting status Miao (ii) Simplification application CS fitting model design, especially suitable indirect aspects daylight scenarios. simplified provides quick feedback promotes concepts. Its accuracy been verified by simulation data from Climate Studio software. (iii) Exploration conditions using software, focusing on ρ′ (the area-weighted average room surface reflectance), ρ reflectance where first reflection occurs), WWR (Window-to-wall ratio) two different types dwellings. also includes defining dwelling parameter intervals necessary an appropriate stimulus (iv) analysis suggests that enhancing greater effect than WWR, indicating increasing should be preferred method achieving high-quality efficient lighting.

Comparison of Simulation Methods for Glare Risk Assessment with Roller Shades

Buildings, Journal Year: 2024, Volume and Issue: 14(6), P. 1773 - 1773

Published: June 12, 2024

Daylight discomfort glare evaluation is important when selecting shading properties. New standards recommend allowable frequency limits but do not specify the modeling accuracy required for annual risk assessment. Fast simulation tools allow users to perform hourly evaluations within minutes. However, reliable of through roller shades requires accurate their specular and diffuse transmission characteristics, affected by color, materials, weaving technology. This study presents a systematic comparison between commonly used methods against “ground truth” Radiance ray-tracing tool rpict in terms daylight probability (DGP), vertical illuminance (Ev), visual frequency. The results are presented two shade fabrics using light models with without peak extraction algorithm (Radiance–aBSDF Radiance–BSDF) component. impact sky/sun discretization on prediction also discussed. show that 5–Phase Method (5PM) superior direct sunlight DGP shades, while other investigated (3–Phase Method, imageless DGP, ClimateStudio Annual Glare) as robust purpose. Users encouraged understand underlying assumptions avoid errors simulating glare, especially due contrast effects.

Published: Oct. 30, 2023

The quality of indoor lighting significantly influences human well-being, emphasizing the need to integrate planning into architectural design process. To optimize conditions, light environment simulations are commonly employed. While much relevant literature clearly shows that widely used predict environments, there is limited active research validating these simulations. Therefore, this study aimed assess alignment between actual measurements and simulations, specifically focusing on daylight-induced glare. achieve this, a comparative analysis verification glare levels were conducted accounted for location direction. Disparities simulated measured revealed contingent These variations primarily arose from simulation’s utilization fisheye field view (FOV) measurement. improve accuracy in it advisable follow standards related perception glare, such as (FOV), instead solely depending FOV. study’s limitations include challenges environmental replication, minor measurement errors, tree branch shading interference. Despite potential not replicate temporary effects, consistent differences with indicate FOV was key contributing factor.
