Question-and-Answer Resource for the Building Energy Modeling Community
 | 1 | initial version |
The most recent version of EnergyPlus (9.3) has a new object called PerformancePrecisionTradeoffs. In that object, the field Zone Radiant Exchange Algorithm gives you the option to override the default ScriptF quadratic radiant exchange algorithm with a linear one called CarrollMRT. That performance improvement should be especially noticeable for zones with many surfaces. [Disclaimer: we are not yet entirely sure about the relationship between zone/surface configuration and CarrollMRT precision degradation.]
