Calculating heat through walls, glass, roofs, and partitions using the Latent Heat Gain: Accounting for moisture from occupants and fresh air. Internal Loads: Heat generated by lighting, equipment, and people. Equipment Sizing:
Cost-Effective: Most templates are significantly cheaper than annual software subscriptions. Conclusion
You can use these standard industry formulas to automate your calculations in Microsoft Excel Base Square Footage Load =[Area] * 25 (Standard estimate: 25 BTU per square foot). Occupant Load =[Number of People] * 400 (Average of 400 BTU per person). Fenestration (Windows) Load =[Number of Windows] * 1,000 (Rough estimate for standard windows). Volume-Based Heat Load =[Length] * [Width] * [Height] * 141 (Commonly used for office spaces with standard equipment). Tonnage Conversion =[Total BTU] / 12,000 (Converts total heat load to HVAC tons). ServiceTitan Industry Benchmarks (Rules of Thumb)
