Developing a Load Calculation Lab for ME 3355: Hands-On HVAC&R Learning at Cal Poly

This project supports the transition to semesters by creating a new load calculation labs for ME 3355, a course focused on the fundamentals of HVAC&R systems. Working with industry-standard software platforms like DesignBuilder/EnergyPlus and HVAKR, students developed a three-part lab series exploring building envelope modeling, zoning, and sensitivity analysis and the differences between the radiant time series and heat balance methods. Exercises include analyzing the impact of design conditions such as weather location, insulation values, and infiltration rates on peak heating and cooling loads. Through this hands-on lab experience, future students will gain practical insight into real-world HVAC&R system sizing, helping bridge the gap between theory and application in building energy performance.
