  • P1 Head P2 feet V2 Head and feet V1 Head and feet Typical Patient Room Boundary Conditions Interior surfaces – 70 deg F Exterior walls – 68 deg F Glass – Night time – no solar radiation No additional internal thermal loads have been accounted for. Infiltration modeled at 0.12 ACH supply condition (at 5 deg F) spread across window frame. BUILDING ENVELOPE - PATIENT ROOM COMFORT STUDY
  • BUILDING ENVELOPE - PATIENT ROOM COMFORT STUDY The Patient Room Comfort Study showed that eliminating the fin tube radiation and installing quad glazing would allow for the same thermal comfort with an initial capital cost savings of $300,000 and operating savings throughout the life of the building.

  • V1 feet P1 & P2 V2 head
      • Summary – The air speed, air temperature, and mean radiant temperature calculated in the CFD models indicates that an all air heating system will maintain thermal comfort in the patient rooms assuming that triple pane glass is used in the window assemblies with a thermally broken frame.
