Among advanced window technologies, aerogel glazing system (AGS) is distinguished by its superior thermal insulation. However, the optical scattering properties of AGS have rarely been addressed in previous simulations of daylight illuminance and discomfort glare. In this study, the optical scattering property of granular AGS with varying particle sizes and filling thicknesses was measured. The diffuse transmission of AGS was considered in the three-phase method based on Radiance to simulate the daylight illuminance and discomfort glare of AGS. Simulation accuracy was validated through an in-field experiment. The impact of haze on daylight illuminance and discomfort glare was further quantified. The results showed that the three-phase method, which accounts for the optical scattering properties of AGS, was found to be reliable. The relative mean bias error (rMBE) and the relative root mean square error (rRMSE) of the simulated horizontal and vertical illuminance, as well as daylight glare probability (DGP), were within 13 % and 4 %, respectively. Moreover, haze was found to significantly influence daylight illuminance and discomfort glare, particularly in sunny days. As haze increased from 0 to 1, the average horizontal illuminance at the front position in sunny days decreased by 6827 lx (≈61 %). Simplifying AGS as either conventional specular glass or a perfect Lambertian diffuser may lead to notable inaccuracies in simulation results.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"286 ","pages":"Article 113765"},"PeriodicalIF":7.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tailored weighting schemes offer practical approaches to synthesize these diverse performance aspects onto a common scale, effectively informing building operations and overall performance evaluations. However, such schemes remain underdeveloped. To address this gap, a stakeholder ontology was first developed to analyze power dynamics and information flows among stakeholders involved in building operational performance. Building managers were identified as key stakeholders to determine weights of such a scheme. Subsequently, building on the Smart Readiness Indicator (SRI) framework, a survey was conducted to calculate the weights for commercial buildings using the Analytic Hierarchy Process (AHP). Inputs from 27 building managers in the Netherlands were collected, along with 13 building owners and 13 international researchers. Results showed that performance aspects were not equally weighted. Building managers prioritized occupants’ health and wellbeing, building service downtime, and occupant comfort, while assigning the lowest weight to operational cost. Building owners and researchers also agreed with these top three priorities. However, considerable individual variation in priorities was observed, even after accounting for stakeholder roles, building types, and country. These findings suggest that the SRI weighting scheme should be adapted to regional contexts and highlight the necessity for customizable building management dashboards tailored to specific building conditions. Finally, the proposed weighting scheme offers pragmatic insights to support decision making in building operations, policy development, certification systems development, and smart building control and management.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"286 ","pages":"Article 113762"},"PeriodicalIF":7.6,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we tested a typical yak dung stove in a local household, used the mass balance method to calculate the dynamic PM<sub>2.</sub><sub>5</sub> fugitive emission rate, and analyzed its chemical composition.

Frequent ignition and loading events led to higher PM<sub>2.5</sub> fugitive emission rates.

To apply paired comparisons for effective learning, subjects compared successive pairs of different visual conditions and indicated their visual preferences through online surveys. Meanwhile, ten small, low-cost, and calibrated cameras captured luminance maps from both the field of view (FOV) of each occupant and non-intrusive viewpoints (on computer monitors, luminaire/ceiling and desk) under various sky conditions and interior luminance distributions. Convolutional Neural Network (CNN) models were developed and trained on luminance similarity index maps (generated from pixel-wise comparisons between successive luminance maps captured from FOV and non-intrusive cameras separately), to classify each subject’s daylight visual preferences. The results showed that the models trained on luminance distributions measured by monitor-mounted and ceiling-mounted cameras produced preference predictions consistent with those derived from FOV cameras, and can reliably learn visual preferences (83–94 % accuracy) in all cases except for locations furthest from the windows.
