In the whole life cycle using intelligent means to save energy consumption, reduce carbon emissions, I think it is feasible, and technical means are also very rich, such as the Internet of things, building automation, intelligent, etc., but now seems to lack of quantitative analysis and evaluation criteria, more is to stay in the concept of the proposed and qualitative analysis. Dear friends, is it feasible to establish a unified calculation, analysis and evaluation standard in the field of energy conservation and emission reduction through intelligent means in the building life cycle?
