For a one-family dwelling, the air conditioning load is assessed at what percentage?

In the context of assessing the air conditioning load for a one-family dwelling, a value of 100% is utilized as the baseline for calculating the required cooling capacity of the air conditioning system. This percentage indicates that the full capacity of the system is determined based on the total cooling load requirements of the home, ensuring that the system is adequately sized to maintain comfort during peak temperatures.

When determining the air conditioning capacity, it's essential to factor in the total heat gains from various sources within the dwelling, including sun exposure, heating from occupants, appliances, and any other contributing factors. By using 100%, the calculations ensure that the cooling system is capable of handling these loads effectively, promoting energy efficiency and occupant comfort.

Calculating the load at anything other than 100% would not provide a true reflection of the requirements, potentially leading to undersized equipment that could struggle to maintain desired temperatures or overly large systems that could lead to inefficiencies and unnecessary energy consumption.
