Cooling Load Check Figures Ashrae Pdf May 2026

“ASHRAE Cooling Load Check Sheet (PDF)” – A one-page checklist comparing W/m² for 12 building types. (Note: Create this as a lead magnet or internal tool.) Author Note: Always refer to the current ASHRAE Handbook—Fundamentals for official tables. Values cited here are for educational illustration of the methodology.

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

Also, They are ±20% accurate at best. They are a filter , not a scale . cooling load check figures ashrae pdf

But does that feel right?

Let’s look at how to use the cooling load check figures to validate your model in under 10 minutes. “ASHRAE Cooling Load Check Sheet (PDF)” – A

Stop using 400 ft²/ton (which equals ~85 W/m²). That ignores windows, people, and latitude.

These tables provide (or Btu/h·ft²) ranges for total cooling loads based on building type and glazing percentage. Suppose your calculation came back at 90 W/m²

Find your building type. Calculate your W/m². Compare. Adjust. Only then do you have an engineering judgement you can defend.
