CO2 Reduction Planning for Energy Efficiency Projects in Bangkok Commercial Office Buildings

Abstract

As a significant contributor to greenhouse gas emissions in the Asia Pacific region, Thailand has pledged to lower its carbon dioxide emissions by 555 million tons by the year 2030. In Bangkok, energy efficiency projects in the large commercial buildings sector are an integral method to reduce emissions and support a lower carbon future. Hence, to support energy efficiency methods, this study develops a methodology to quantify the emissions reduction and cost savings potential to optimize decision-making in CO2 emissions reduction project planning over the next five years. The results indicate that, among the energy efficiency methods considered for large commercial buildings, AC installations are the most costeffective method, whereas chiller installations offer the most CO2 reduction potential. Regarding project planning, results also indicate that with the current goals, additional measures about CO2 emissions may be required to meet the country's targets.
