Carbon emissions and energy consumption control are urgent issues in many fields. In the construction industry, which accounts for 34% of carbon emissions, wooden buildings are a potential solution for an environmentally friendly transformation. How to build a life-cycle assessment system and realize the climate-based selection system for wooden buildings is a problem. This paper reviews existing criteria for assessing carbon emissions and energy consumption. It applies Life Cycle Assessment modeling and the Multiple Criteria Matrix to establish a comprehensive low-carbon, zero-energy assessment system to support the entire design process. Compared with existing studies, the life-cycle assessment system for wooden buildings proposed in this paper integrates established carbon emissions and energy consumption assessment criteria and offers a comprehensive method to control their life-cycle carbon emissions.
