CONSTRUCTION OF THE ENVIRONMENTAL LOAD EVALUATION MODEL CONSIDERING LIFE CYCLE ACTIVITIES OF COMMERCIAL BUILDINGS

Abstract

Concerning environmental load reduction effect from the commercial buildings, the method for evaluating multiple effects of environmental load reduction countermeasures was constructed. In particular, we built a model about CO₂ emissions. The model made in this research combines building energy load model, air conditioning system evaluation model and building stock quantity stochastic model. This model incorporated the module to calculate CO₂ emission of constructing buildings and demolishing buildings. This model can calculate the CO₂ emission of commercial building sector of Japan. Using this model, we evaluated the difference of the CO₂ reduction effect according to scrappage rate of buildings under various CO₂ reduction countermeasures in buildings.
