Improved Treatment of Weather Conditions in the Radiant Time Series Method

摘要

This paper provides an overview of recent refinements to the radiant time series method (RTSM) as part of ASHRAE Research Project RP-1616. These refinements include replacing the ASHRAE three-parameter (A, B, C) clear-sky model with a new globally applicable model, introducing new design-day temperature profiles, updating the weather data, and improving the treatment of interior shading in the fenestration model. In addition, the sensitivity of the calculated cooling loads to the weather-related refinements is investigated with a parametric study.
