Heat Gain from Lighting Calculator

This calculator estimates the heat gain from lighting fixtures in a space, considering power consumption, ballast factor, and cooling load factor (CLF).

Key Parameters:

• Watts: Total power consumed by lighting, measured in Watts (W).
• Ballast Factor: Accounts for extra power used by ballasts in certain lighting systems (typically 1.0 to 1.2).
• Cooling Load Factor (CLF): Represents how much heat is instantly added versus stored and released later (ranges from 0 to 1).

Applications:

• HVAC System Design: Helps size equipment and design efficient air distribution systems in offices, stores, and warehouses.
• Energy Efficiency Analysis: Identifies opportunities for lighting upgrades and control strategies to reduce energy use.

Why Include in Environmental Calculators?

Lighting contributes significantly to heat gain, affecting HVAC performance and energy consumption. Including it ensures accurate cooling load calculations.

Conclusion:

Understanding and calculating heat gain from lighting is essential for efficient HVAC design and energy management.
