Housing demands in Indonesia cause an increase in the supply needs of building materials where some of these materials have a negative impact on the environment. Life Cycle the assessment (LCA) method is used to assess the potential environmental impact caused by housing demand of low-cost housing in Indonesia which its types are standardized to types of 21, 36, and 45.

The data of building materials were collected from some developers involved in the development of low-cost housing. Embodied Energy (EE) and Carbon Emission (CE) were used as indicators of LCA. The result of the study showed that EE and CE value is increasing linearly by the addition of housing areas. It was also found that material volume has significant value to rise Embodied Energy and Carbon Emission. Based on the result, with the same volume of square meters, the amount of energy used to build two types of houses 21 was higher than the type of 45 houses.
