https://communities.bentley.com/products/building/building_analysis___design/f/energy-simulation/225296/heat-loss-calculationHi I have model the building with 75 rooms and warm floor as heating type. the result only shows the plant ratio of 1 and pre-heat period of 0. However, I am look at different plant ratios and pre-heat period hours. Thank you!en-USTelligent Community 12https://communities.bentley.com/thread/698240?ContentTypeID=1Wed, 23 Feb 2022 13:17:30 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e219c5b5-f280-4c38-a86c-ff9a2ba647acShane Regan<p>Great to hear!
