Also, They are ±20% accurate at best. They are a filter , not a scale .

Stop using 400 ft²/ton (which equals ~85 W/m²). That ignores windows, people, and latitude. cooling load check figures ashrae pdf

Open your ASHRAE Handbook—Fundamentals. In the current edition (2021/2025), Chapter 18 (Nonresidential Cooling and Heating Load) contains the gold mine: Table 9 & 10 , typically titled “Cooling Load Check Figures for Typical Commercial Buildings.” Also, They are ±20% accurate at best

Let’s say you modeled a 2,000 m² (21,500 ft²) mid-rise office building (perimeter zones). Your software says total cooling load = 280 kW . That ignores windows, people, and latitude

Let’s look at how to use the cooling load check figures to validate your model in under 10 minutes.

Suppose your calculation came back at 90 W/m² for a retail store (ASHRAE range 150–250). You are 50% low . Something is wrong.

These tables provide (or Btu/h·ft²) ranges for total cooling loads based on building type and glazing percentage.
