By following these steps, you can build a custom tool that rivals commercial software, giving you total control over your design process.
Proper cooling load calculations are split into two categories:
Divide the total cooling load by 12,000 to determine the required HVAC equipment tonnage.
Use color-coding to differentiate between input cells, calculated outputs, and reference data tables.
People, lights, and appliances generate substantial heat that reduces winter heating needs but drastically increases summer cooling loads:
