Gray predicting theory and application of energy consumption of building heat-moisture system

This paper discusses the difference between other uncertain theories such as stochastic and gray system one and the uncertainty of building heat-moisture system. The other prediction techniques are simply analyzed, and gray prediction theory is stated. A method based on gray prediction model is proposed. Building energy consumption for a certain example is predicted. By inspecting, predicting values agree with measured one very much, that is, the GM(1,1) model compares with the original load data. The method can be seen as a new load calculation method and applied for verification purposes.
