1. What is BTU per Square Meter?

BTU/h (British Thermal Units per hour) per square meter is a measurement of heating or cooling capacity needed for a given space. It helps determine the appropriate size of HVAC equipment for a room or building.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Area \) — Area in square meters
• \( 215 \) — Conversion factor (approximately 20 BTU per square foot converted to square meters)

Explanation: The formula provides a rough estimate of the BTU requirement based on area alone. More precise calculations would consider insulation, climate, and other factors.

3. Importance of BTU Calculation

Details: Proper BTU calculation ensures your heating or cooling system is appropriately sized - neither too small (inefficient) nor too large (short cycling, higher costs).

4. Using the Calculator

Tips: Simply enter the area in square meters. The calculator will estimate the BTU/h required for that space. For more accurate results, professional load calculations are recommended.

5. Frequently Asked Questions (FAQ)

Q1: Is 215 BTU/m² accurate for all situations?
A: This is a general estimate. Actual needs vary based on insulation, climate, ceiling height, and other factors.

Q2: What if my room has high ceilings?
A: For ceilings over 2.7 meters, increase the BTU estimate by 10-25% depending on height.

Q3: How does this compare to BTU per square foot?
A: 215 BTU/m² is approximately equivalent to 20 BTU/sq ft (1 m² = 10.764 sq ft).

Q4: Should I round up the BTU result?
A: It's generally recommended to round up to the nearest available equipment size, but avoid significant oversizing.

Q5: What about cooling vs heating requirements?
A: This calculation works for both, but heating needs may be higher in cold climates while cooling needs may be higher in hot climates.
