Abstract
There are many practical calculation methods of design air-conditioning load, but accuracy of design load obtained by these methods has been rarely examined. This paper discussed on precision of design air-conditioning load calculated by popular practical method. We asked some designers belonging to construction company or design office, for design load estimation in example case used by each designer's calculation method, and analyzed precision and characteristics of these load value. Nextly, we picked up two representative practical methods of design load calculation and made clear how much design loads are overestimated or underestimated compare to the reference range set by precise calculation.
