| Abstract |
Building energy analysis can be categorized into steady state, quasi-steady state and dynamic methods. The current Korean building energy
standards relies on ECO2 that is based on the quasi-steady state approach. For the purpose of clarity and simplicity, ECO2 is designed to
receive deterministic inputs only, and allow for predefined usage profiles such as occupant/lighting/equipment schedule. In this regard, the
authors examine technical disadvantages caused by ECO2: (1) unrealistic geometric and HVAC modeling, (2) non-adjustable default input
fields, (3) lack of validation for building energy models and users, (4) no account for building’s stochastic characteristics, (5) lack of
usability in energy-conscious decision making. This paper proposes further recommendations for the Korean building energy standards. |
