In solar analysis, the horizontal-to-tilted irradiance conversion is mostly performed through separation and transposition models, whose accuracy varies considerably depending on the modelled scenarios (i.e., sky conditions, surface orientation, latitude). Therefore, exploiting a single model chain to conduct solar analysis can hardly be the most effective strategy. This study presents insight into a novel approach that combines the best-performing solar model chain for each building surface to improve the results’ accuracy. The Zero Emission Building (ZEB) Laboratory in Trondheim (Norway) is considered as case study. One-minute solar irradiance data are collected by the five pyranometers installed on facades and rooftop of the ZEB Laboratory. Solar analyses are performed between June \(20^{th}\) and September \(22^{nd}\) , which coincides with the time of the year with the highest number of hours of sunlight in Trondheim. The effectiveness of both the conventional and the proposed approach is estimated through statistical indicators, i.e., standard deviation of residuals, coefficient of determination, and root mean square deviation.

摘要

In solar analysis, the horizontal-to-tilted irradiance conversion is mostly performed through separation and transposition models, whose accuracy varies considerably depending on the modelled scenarios (i.e., sky conditions, surface orientation, latitude). Therefore, exploiting a single model chain to conduct solar analysis can hardly be the most effective strategy. This study presents insight into a novel approach that combines the best-performing solar model chain for each building surface to improve the results’ accuracy. The Zero Emission Building (ZEB) Laboratory in Trondheim (Norway) is considered as case study. One-minute solar irradiance data are collected by the five pyranometers installed on facades and rooftop of the ZEB Laboratory. Solar analyses are performed between June \(20^{th}\) and September \(22^{nd}\) , which coincides with the time of the year with the highest number of hours of sunlight in Trondheim. The effectiveness of both the conventional and the proposed approach is estimated through statistical indicators, i.e., standard deviation of residuals, coefficient of determination, and root mean square deviation.
