Aiming at a comprehensive assessment of energy-saving retrofitting effect on existing buildings, a calculation method is developed to adjust energy-saving quantity in standard condition for comparison under the same conditions. A mathematical model, method theory and calculation steps are given. Error analysis results show that this method can be applied accurately to practical engineering projects. In a case study of energy-saving quantity assessment before and after retrofitting on a certain hospital in Shanghai, with energy simulation software TRNSYS, detailed application of this method is introduced and analyzed. The method is applied to the case of energy-saving quantity assessment to a hospital in Shanghai before and after retrofitting with the energy simulation software TRNSYS.
