Room Cooling Load (BTU/h)

Estimate a room's cooling load from its area, use, occupancy, glazing and fresh air — tuned for Indonesia's hot, humid climate. Get the load in kW, TR and BTU/h with a full breakdown and a recommended unit size.

Floor area

Room use Sets default occupancy & equipment — adjust below if needed.

Occupants

Lighting + equipment (W/m²)

Window / glass area (m²)

Glass exposure

Fresh air per person (L/s) ~10 L/s per person typical; drives the humid-climate latent load.

Method: component sum — internal gains (lighting, equipment, people sensible & latent), solar through glass, envelope, and fresh-air sensible & latent at Indonesian design conditions (outdoor ~33 °C / 70% RH, indoor ~24 °C / 55% RH). Results run higher than temperate rules-of-thumb because of the humid-climate fresh-air load. Indicative only — for tender or installation we run a full room-by-room calculation. Get a quote.

From Load to Cool Building

Once the loads are set, we design, supply, install and commission the chiller plant or VRV system to match.
