Improvements to fan-curve cooling units
October 8, 2026: the report went back to an earlier design, so jobs from that day on no longer get the redesigned Summary Report described below. The other changes in this release still apply. Ask us if you need to know which report a job’s results are in.
Cooling units defined by a fan curve now account for air density more accurately when they remove heat from the room. Results for rooms cooled by these units can differ from earlier runs.
Page 1 of the Summary Report now opens with the verdict, four headline figures and the key findings, so the result reads at a glance. On October 8, 2026, it was withdrawn: see the note under this release’s headline.
The temperature solution is stabilized from the first iteration, which helps more models converge.
Models that list a plain block ahead of a PDU or HDU now go through solver setup reliably.
