Abstract:
Using Markowitz mean-variance model, the form and current situation of the existing buildings′ energy-efficiency renovation at present stage was analyzed. And from the aspect of urban architecture environment energy-efficiency renovation, considering fully the fuzzy uncertainty compensation benefits mode of existing buildings′ energy-efficiency renovation at current stage, an combination optimal model for existing buildings′ energy-efficiency renovation compensation is proposed to attain the maximize overall effectiveness of energy saving after existing buildings′ energy-efficiency renovation using the minimum compensation cost. Taking the buildings′ energy-efficiency renovation in Nanchang area for example, the feasibility of the model was verified by real calculation.
