A controlling method and a controlling system for saving energy of a building are provided. In the present method, a user environment requirement is obtained first. Then, a plurality of cover ratios of a sunshade device on an opening of a building is defined, and according to an environment parameter and the user environment requirement, a total electricity consumption required by air conditioning equipment and by lighting equipment in the building corresponding to each of the cover ratios is calculated. Finally, a cover ratio that produces the minimum total electricity consumption is obtained, and the sunshade device, the air conditioning equipment and the lighting equipment are adjusted according to the obtained cover ratio, so as to make the building meet the user environment requirement and maintain a status of the minimum total energy consumption.
