According to industry standards, what is the sensible heat gain for a full-time occupant in a residential structure?

The sensible heat gain for a full-time occupant in a residential structure is often estimated to be around 230 BTUH (British Thermal Units per Hour). This figure is important for HVAC system design, as it helps in determining the heating and cooling loads necessary to maintain a comfortable indoor environment.

Sensible heat gain refers specifically to the increase in temperature in a space due to the heat produced by occupants as they engage in their daily activities. This value incorporates factors such as metabolic heat production, which varies based on the activity level of the occupants, as well as other sources of heat that may affect comfort levels indirectly.

Choosing 230 BTUH aligns with common industry practice for residential settings, where this value has become a standard reference point across various calculations and HVAC system designs. Understanding this fixed value aids contractors in effectively sizing systems and ensuring that they are adequately equipped to handle the thermal loads presented by occupants.
