摘　　要：Energy retrofitting is argued to be the most feasible and cost-effective method for improving existing buildings’energy efficiency.As a sustainable development,build-ing energy retrofits require the consideration and integration of all three sustainability dimensions:environmental,economic and social.The objective of this study is to estimate and compare the sustainable impact of building energy retrofits to determine the maximum sustainable benefit when implementing different energy-related mea-sures.The proposed analysis consists of integrating three approaches for evaluating these benefits.Economic benefits are measured by estimating the payback period of energy-related measures,environmental benefits are measured by estimating the CO_(2) equivalent saving per year due to the implementation of energy-related measures,and social benefits are measured by defining a“social impact index”that establishes the impact of energy-related measures on buildings’users.A case study is used to demonstrate the framework for four potential scenarios.The results show that for the case study,energy-related“controlling”and“upgrading mechanical system”measures have the highest sustainable impact among the identified energy retrofitting measures.
