In past two decades ASHRAE standard 90.1 (ASHRAE
2013
) has presented a
comparison method mostly based on energy modeling simulation results to enhance
the system selection procedure. This standard represents a base system for each type
of building application and the designer has to perform two separate energy con-
sumption simulations and then compare the results of his design simulation against
the base system simulation. If the design building/system energy consumption
shows to be lower than the one from the base building/system, then the selected
system is acceptable from the energy standard point of view. The outcome of this
exercise is the ground for gaining points in building energy effi ciency scoring sys-
tems such as LEED.
A possible alternative method (I have described the structure of such method in
Chap.
13
) can be defi ned as performing multiple simulations for larger numbers of
systems and evaluation of the results in a risk based methodology. In this method the
designer should perform multiple risk-based simulations (not a basic deterministic
type simulation) and compares the results before selection of the most energy con-
scious system for the design application. By utilizing such system one can present the
advantages and disadvantages of each possible system in a probabilistic language.
