Optimizing design scheme of energy saving in warehouse building based on grey relational analysis

Energy saving and environment have became an important subject in the design of warehouse building. In order to optimize a design scheme in warehouse building, this paper studied the optimizing design method in warehouse building by grey relational analysis. The weighting value for indexes of green building evaluation, such as area ratio of windows; heat pump air-conditioning; acoustics etc, were made by Delphi method. The matrix for comparative series of different design scheme was calculated by grey relational analysis. The design scheme with area ratio of window and natural ventilation is the most optimizing design scheme. The results indicate that grey relational analysis can be a valuable method for the optimizing design scheme for warehouse building.
