What is the significance of Heat Transfer Multipliers (HTM) in Rhvac’s load calculations?

Heat Transfer Multipliers (HTM) are used to account for the thermal bridging effects of various construction materials in Rhvac’s load calculations. By automatically looking up HTM values for walls, windows, doors, and roofs from ACCA Manual J, Rhvac ensures accurate calculations of heat gain and loss through the building envelope. This enables designers to optimize their HVAC system design and sizing for optimal performance and energy efficiency.
