To permit a complete understanding of the VAV system, we must look at it from a system level. In this section we will explore a few common space types and how VAV systems address the cooling and heating needs associated with them.

Perimeter (P) Versus Interior (I)

Figure 56

For simplicity, a typical building can be described as having two types of spaces, perimeter and interior.

In many climates, perimeter spaces with walls and windows exposed to the outdoors require seasonal cooling and heating. Such spaces require cooling in the summer: it is warm outside, the sun is shining through the windows, people are occupying the space, and the lights are on. In the winter, when it is cold outside, these spaces require heating to offset the “skin” heat loss through the exterior walls and windows.

Most interior spaces require year-round cooling due to the absence of skin heat losses and the fairly consistent amount of heat generated by people, lights
