The highest contribution rate among the incremental costs of green buildings is the incremental cost of energy conservation. The incremental costs of green buildings include the following:

The cost content can be divided into three categories: soft costs, green building technology costs and certification costs. Soft costs mainly refer to soft technical costs in the green building process, including design costs, analytical costs, management costs, debugging costs, etc. Green building technology costs are mainly design costs, which are additional funds generated during the application of green building technologies.

Certification costs mainly refer to the costs used in the green building system certification process, mainly referring to expert review fees. The application of green building technology in my country varies greatly, and a complete technical system has not yet been formed, and the technical algorithms vary widely. The current status of green building construction directly leads to huge differences in the incremental costs of green building technologies.

Notes:

The calculation of the incremental cost of green buildings requires the selection of a baseline building plan, and relative to the baseline building plan, green buildings are also affected by factors such as price during their lifespan. Factors and the impact of time value, these issues have a crucial impact on the incremental cost of green buildings.

The incremental cost of the green building throughout its life cycle refers to starting from the project perspective, based on the benchmark building plan data that meets the regional mandatory standards within a certain period of time, excluding the cost during the project process. After adjusting for factors such as time and price, the intangible and tangible costs increased by energy-saving methods and measures during the entire life cycle.
