The contribution ratio of indoor climate (CRI) derived from computational fluid dynamics (CFD) was developed to estimate the individual contribution of heat factors to any location inside a room. The CRI index indicates the structure of the temperature field and allows the CFD results to be applied to analysis and design, with more efficient application. In this study, the concept and calculation method for CRI is introduced first. As an example of the application of CRI, a method for predicting temperatures at any point in a room with a small number of temperature sensors based on CRI is developed. The accuracy of the method is examined by comparing the prediction with a coupled simulation of CFD and radiation.
