Cooling Load Check Figure [upd]

COOLING LOAD CHECK FIGURE

Recommendation: Acceptable for preliminary design. Consider fine-tuning internal loads (currently 35% above typical).

(kW / BTU/h / Tons)

Total Calculated Load: 48.2 kW (13.7 tons) Floor Area: 5,000 ft² → Load per ft²: 27.4 Btu/h·ft²

The cooling load check figure is not a substitute for a detailed load calculation (like using HAP, Trace 700, or Manual J), but it is a mandatory . It answers the question: "Did I make a typo or a logic error in my calculation?" cooling load check figure

The provides a quick, at-a-glance validation of calculated cooling loads against expected ranges based on building type, climate zone, and floor area. It helps engineers and designers catch input errors or unrealistic assumptions before finalizing equipment sizing.

A is a "rule of thumb" used by HVAC engineers and contractors to quickly estimate the cooling capacity (in BTUs or Tons) required for a building before performing detailed manual or software calculations. These figures are typically expressed in square feet per ton (sq. ft/ton) or BTUs per square foot (BTU/sq. ft) . It answers the question: "Did I make a

While useful, relying solely on check figures is the #1 cause of HVAC system failure.

| Building Type | Standard Range (sq ft/ton) | Standard Range (m²/kW) | | :--- | :--- | :--- | | | 500 – 700 sq ft/ton | 13 – 18 m²/kW | | Residential (High Performance) | 1,000+ sq ft/ton | 26+ m²/kW | | Office Buildings | 250 – 400 sq ft/ton | 6.5 – 10.5 m²/kW | | Retail / Shops | 250 – 350 sq ft/ton | 6.5 – 9 m²/kW | | Server Rooms / Data Centers | 50 – 150 sq ft/ton | 1.5 – 4 m²/kW | | Restaurants (Dining) | 150 – 250 sq ft/ton | 4 – 6.5 m²/kW | These figures are typically expressed in square feet

The industry standard unit for check figures is or Square Meters per Kilowatt (m²/kW) .
