In C3IAM/NET, the residential and commercial sectors part can be used to simulate the energy flow of building equipment (such as coal stove, air conditioner, water heater, etc.) using various kinds of energy (coal, oil, natural gas, electricity, solar energy, biomass and geothermal energy) to meet the service demand (space heating, cooling, hot water, cooking, lighting and others), so as to calculate the energy consumption and GHG emissions of various equipment combinations. The technology pathway with the optimal cost can be obtained under the constraints of specific realistic conditions, and meet the energy service demand of buildings at the same time. Energy service demand prediction module, energy - environment - technology - policy evaluation module and output module make up the residential and commercial sectors of C3IAM.
Based on socioeconomic variables, climate conditions and related policy planning, the energy service demand prediction module determines the future demand of the residential and commercial sectors for space heating, cooling, hot water, cooking, lighting and other energy services.
Energy - environment - technology - policy evaluation module aims to minimize the total cost, on the basis of multifaceted data such as energy service demand from the energy service demand prediction module, investment costs, operation and maintenance costs, energy efficiencies, energy prices and carbon emission factors. Technical progress is represented as efficiency improvements and cost reductions here. The constraints include carbon emission, energy supply, policy restriction and technical level.
Output module shows the total energy consumption and GHG emissions of the residential and commercial sector from 2020 to 2060. Indirect emissions from electricity are also taken into account. The energy structure and emission sources can also be distinguished and analyzed. Besides, the output module provides the development pathway of each kind of device.
