A general evaluation system is designed for the building integrated energy system to provide reference for system design. By using multi-objective analysis method

14 sub-indicators are defined from three perspectives of energy consumption

environment and economy. Based on MATLAB software

the weight coefficient of each index is determined by using absolute analytic hierarchy process(AHP) and the coefficient of variation method. The system is applied to three building-type integrated energy system projects. Each indicator is calculated and dimensionless according to the determined reference range. The comprehensive score of each project is calculated according to the weight coefficient. The results show that the score of Project 1 is the highest. Its comprehensive energy utilization

clean energy ratio

system thermal efficiency

environmental indicators and economic indicators are in the normal range

while the energy saving rate and cooling efficiency are low

which can be optimized at the later stage. The evaluation system proposed is different from the conventional energy system

it considers the factors such as the energy quality

energy storage and proportion of clean energy

and it has certain universality.
