Abstract—The marginal abatement costs of energy reduction in designated factory and building are presented. The common energy conservation technologies discussed in this paper are LED, air-conditioner, chiller, motor, boiler and furnace. Results from MAC curve indicate that abatement cost of energy reduction ranges from 2,871.63 to 37,379.24 THB/tCO₂eq, where boiler gives the highest investment cost for the reduction of energy and CO₂ releasing to atmosphere. On the other hand, LED and motor offer low investment cost to reduce energy use and CO₂. Large GHG emission reduction comes from equipment powered by electricity in both factory and building. Results from MAC curve can be used to prioritize which energy conservation measures will reduce the most energy use and CO₂, or which technology should be invested.

Index Terms—Marginal abatement costs, energy efficiency, factory, building.
