Study on Energy Consumption Evaluation for Public Buildings Based on AHP-FCE Model with Dynamic Weight

This paper proposes AHP-FCE model with dynamic weight for the operational phase of school public building, to determine the energy saving coefficient of unit Office, and then evaluate energy efficiency of the whole building during running period. Paper introduces the concept of degree of weight effect, to quantify the impact of factors on the overall evaluation result, explains the idea of energy saving coefficient, to measure the building energy efficiency. Based on degree of weight effect, we get weight adjustment vectors to calculate energy saving coefficient. Through the energy monitoring system based on Green IT, paper shows that the proposed model can reflect the energy efficiency accurately and in time, rather than simply reflect how much energy is consumed.
