lack of proper air quality even though energy costs are low. ‘‘Waste
not, want not’’ is the energy motto. ‘‘Use what you need, but need what
you use’’ is a corollary. See Ref. 8 for more on this topic.

Summary
A first-hand knowledge of engineering fundamentals is a must for
HVAC designers. All problems are helped toward solution by an ability
to think clearly, to move from problem definition to identification of
alternatives, to evaluation of alternatives, to selection and implemen-
tation of preferred action. Knowledge of political constraints (codes
and regulations) as well as technical and ethical factors is an impor-
tant part of the designer’s tool kit. Knowledge of fundamental engi-
neering physics in fluid mechanics, thermodynamics, heat transfer,
psychrometrics, and sound control is absolutely essential to the HVAC
designer. Energy conservation in system design has become a moral
imperative. An understanding of these fundamentals will make all
other issues treated in this book easier to understand.
