In the evolving world of building energy design, the story of is a shift from simple, fixed-flow calculations to a complex, multi-layered simulation of precision and efficiency. The Problem: Beyond the Standard Unit

For decades, HVAC modeling focused on traditional units where a single compressor and condenser were matched to a single evaporator. These systems were binary—on or off—and struggled with "part-load" efficiency. When a large building had dozens of rooms with different needs, modeling them required assuming a massive, inefficient central plant.

Advanced "Heat Recovery" models allow the system to cool one room while using the captured heat to warm another, drastically increasing efficiency. The Model: Replicating Complexity In the evolving world of building energy design,
