Summary: This study proposes two methods, M5-PM(A) and M5-PM(B), for calculating direct sunlight contribution in building dynamic daylight modeling. Compared to the traditional method, M5-PM(A) can reduce computation time by 73% and 67% for modeling PDRF and specular blind systems, respectively. The results also show that M5-PM(A) has similar simulation accuracy to the traditional method for modeling PDRF systems and slightly improved accuracy for modeling specular blinds. M5-PM(B) inherits the parametric analysis capabilities of the traditional method and significantly accelerates computation speed.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.
