There exists the shortage of holistic building energy efficiency assessment models which consider the uncertain or incomplete information

whereas most previous studies focus on building energy consumption via computer simulation.To tackle the above deficiency

an energy assessment and labeling model of residential buildings was proposed based on the theory of evidence and the national and local building erergy efficlency standards.A method has been achieved by applying the model in residential buildings in hot summer and cold winter area.A computer software toolkit was developed based on the above method.To demonstrated and validated the proposed method

a case study was addressed with the software toolkit.Meanwhile

the same project was assessed with the ‘Assessment standard for energy efficient buildings’.It is found that the two methods are in good agreement and the proposed method can deal with the uncertain information.
