## How We Calculate BTU for Singapore

Singapore's tropical climate means your aircon works harder year-round. We apply a **+25% climate adjustment** on top of the base calculation (500 BTU/m²) to ensure your unit can keep up during peak heat and humidity — not just at ideal conditions.

-   +10% for high ceilings (above 2.5 m)
-   +10% for west-facing or full sun rooms
-   −10% for north-facing or shaded rooms
-   +4,000 BTU flat addition for kitchens
-   +600 BTU per additional person beyond one
