Building Energy Modeling Explained: Degree Days, Bin Method & Hourly Simulation

Why do most HVAC systems spend 99% of their operating life at part load? This video breaks down the science of Building Energy Modeling, exploring how engineers predict energy consumption and optimize life cycle costs. We explain the three core modeling tiers: Degree Days, the Bin Method, and detailed Hourly Simulation. Learn how balance point temperature, variable efficiency curves, and the critical difference between sequential and simultaneous simulation engines impact accuracy. We also cover the limitations of steady-state models, how the bin method handles variable equipment performance, and the computational power required for modern commercial building simulations. Understanding these concepts is essential for achieving energy code compliance and designing high-performance buildings.
