Key drivers for the 2021 Excel sheet evolution:
: Calculated totals for Sensible Heat (temperature change) and Latent Heat (humidity control). Core Formulas for Excel Implementation
Specialized formulas for moisture gain from fresh air, occupant humidity, and equipment. Sizing & Airflow:
Internal heat loads from occupants, lighting, and appliances. Infiltration and ventilation requirements. Key Components of the 2021 HVAC Excel Sheet
Modern homes are built much tighter than older ones. Your calculation sheet should have dynamic fields for Air Changes per Hour (ACH) to account for "tight" vs. "leaky" construction.
To build a functional 2021-style calculation tool, your spreadsheet should include the following sections: Project Information
