| Abstract |
ECO2 is the de facto building energy calculation tool in South Korea; it prescribes deterministic usage profiles such as people, lighting,
equipment and ventilation. However, it has been widely acknowledged that such deterministic approaches cannot take into account stochastic
thermal behavior in buildings. With this in mind, the authors investigated the difference in building energy prediction between deterministic
and stochastic approaches. For the stochastic approach, EnegyPlus, one of the most advanced dynamic building simulation tools, was selected.
Latin Hypercube Sampling was employed to generate 1,000 simulation cases of the DOE medium-office reference building. It is found that
there is a significant difference between deterministic and stochastic approaches. It is suggested that the stochastic approach must be
considered for rational decision making of building energy certification rating. |
