Greenhouse value engineering assessment

Greenhouse value engineering(GVE) is a economics means, used to reduce the total cost of greenhouse at most, by analyzing the greenhouse's functions, which can meet the needs of user well. The greenhouse value coefficients (GRC) are not uniform. The coefficients of the steel framework, enclosed structure and materials, water heating equipment and environmental control system are relatively low. The reason lies in that there is no any suitable standard to design a greenhouse, even on the professional material and environment controlling over greenhouse. Designers could improve the functions of greenhouse at proper cost by GVE. It will help users to choose a best scheme.
