The air temperature surrounding a building is designated as ambient temperature. This term refers to the temperature of the air in the environment around the building, which can have significant implications for load calculations in HVAC design. Understanding ambient temperature is crucial because it influences how much heating or cooling will be needed to maintain a comfortable indoor climate.

In load calculations, ambient temperature is the baseline against which other temperatures (such as indoor temperature or design temperature) are compared. It helps in assessing the thermal performance of the building's envelope and systems, thereby impacting energy efficiency and comfort levels.

The other terms mentioned have specific meanings that set them apart. Operational temperature refers to the temperature at which systems or equipment are used or expected to perform. Calculated temperature typically relates to temperatures derived from specific formulas or models within a given context. Design temperature refers to a predetermined temperature selected for the purpose of designing a heating or cooling system, usually based on specific outdoor temperature conditions that the system should be able to handle. Each of these terms serves its purpose in engineering and design but does not capture the general environmental context as ambient temperature does.
