latent heat (heat associated with moisture/humidity). External Loads: Conduction: Heat transferred through the building envelope, including exterior walls, roofs, and floors. Solar Radiation: Direct and diffuse heat from the sun entering through windows and skylights. Infiltration & Ventilation: Outside air entering through cracks (infiltration) or intentional fresh air intake (ventilation). Internal Loads: Occupants: Heat and moisture dissipated by people based on their activity levels. Lighting: Heat generated by various light fixtures. Equipment: Heat emitted by appliances, computers, machinery, and other electronic devices. h2x +6 Common Calculation Methods Industry standards, primarily established by ASHRAE , offer several methodologies for these estimates: 14 sites Cooling Load Estimation for HVAC Systems | Air Conditioning Sensible Loads Sensible heat gain is the direct addition of heat to a space,which shall result in increase in space temperatures. ...
