Applications for HVAC Systems Sizing and Optimization


Uses a flexible schematic component-based approach that enables you to quickly assemble HVAC plant and control systems.


HVAC Loads Sizing Calculations based on the ASHRAE Heat Balance method. ASHRAELoads can be linked with SunCast for solar shading and ApacheHVAC for System and Plant sizing.


Calculate heat loss and gain calculations based on the CIBSE Guide.
