New in May 2026
Heatpunk UK has been updated to enact various MCS changes to operating temperature and air change rates.
- Operating temps for post-2006 buildings have been increased in almost all rooms.
- Air change rates now default to 0.5 for all rooms except internal.
- Using the standard ventilation method now uses a fixed default air permeability of 12 m³/h.m² @ 50 Pa rather than using an occupancy-based estimator as before.
