Abstract: This study aims to evaluate greenhouse gas (GHG) emission in the unit of kgCO2e/m2 from construction materials of low income houses under the Baan Eua-Arthorn Project. The activity data of constructing materials were extracted from house plans and Bill of Quantities (BOQ) of 4 low income houses such as detached house (61.97 m2), twin house (109.67 m2), townhouse (552.20 m2), and condominium (2,121.15 m2). The greenhouse gas emissions in the unit of kgCO2 e/m2 were calculated in the scope of cradle to gate following the Thai national guideline for carbon footprint of product and Thai national life cycle inventory database (TGO, 2011). Results show that the highest greenhouse gas emission from constructing materials belongs to condominium (179.06 kgCO2 e/m2), followed by townhouse (118.73 kgCO2e/m2), twin house (107.53 kgCO2e/m2), and detached house (93.21 kgCO2e/m2), respectively. The largest greenhouse gas emission was emitted from condominium due to more concrete and cement used than other houses. Concrete, cement and steel were found to be significant emission hot spot which is consistent with the study of Aneksaen (2011). Thus, in order to reduce the greenhouse gas emission from construction materials, the conventional building envelops should be replaced by low carbon embedded materials, like lightweight concrete. It is found that the greenhouse gas emissions (kgCO2 e/m2) decrease to 28% for condominium, followed by 10.4% for townhouse, 6.4% for twin house, and 4.2% for detached house. The results of this study can be used as a guideline to reduce carbon footprint of residential buildings in the government housing project in the future.
