In the world of building performance and energy simulation, fidelity matters.
For simulations to serve as reliable guides—not just during design but through a building’s operational life—the accuracy of inputs like weather data and operational profiles cannot be overstated.
Two key techniques that push the frontier of accuracy are the use of Real Time Year (RTY) weather files, and monthly-calibrated simulation models. Together, these tools provide a powerful platform for optimising energy use and ensuring HVAC systems perform as intended, month after month, year after year.
