The population growth in Indonesia is 1.4% per year, it will meet 800.000 units housing requirement per year. The housing has developed as massal construction and continuously, it will need a large of building materials supply. Therefore, it is necessary to prevent a large carbon emissions occurance, and the exploitation of natural resources controlling for building materials procurement. The carbon emissions could be converted from Embodied Energy (EE) value of building materials since the planning phase of the building lifecycle. In this research, EE building material calculation method developed as Analisis Satuan Material (ASM) based on Analisis Harga Satuan Pekerjaan (AHSP) that commonly used in Indonesia. The ASM consist the type of building material, material unit and material volume of the building. Low-cost housing is the specific object in this research. EE calculation method use the ASM approach and requires the Inventory Data of EE building materials supporting. This study refers to Inventory Carbon and Energy (ICE), Bath, United Kingdom to collect a new inventory data EE building materials for low-cost housing in Indonesia. The EE values of building materials calculation are counted for all types of lowcost housing, are; 21 type (EE value = 126.93 MJ), 36 type (EE value = 145.51 MJ), and 45 type (EE value = 184.59 MJ). The significant factor that causing the low-cost housing have high EE building material value is volume of building materials usage. The bricks (35%-45%) and roof tiles (45% -55%) has contribute the highest of EE value in low-cost housing types, it found in wall and roof covering building component. Mitigation of environmental impacts have to do base on EE value of building materials consideration. The proposal to mitigate by EE values consideration, are ; a) The efficiency of building materials volume calculation, b) Optimization of low-cost housing designs in the efficiency of building materials usage, c) Substitution of building materials that significantly contributes to high EE values in buildings. Mitigation of environmental impacts based on EE value of building materials becomes important in determining the design decisions and building materials usage preferences. EE value of building material considerations are supported by Embodided Energy Calculation Software application development. It should be promoted continuously to build public awareness and willingness for environment controlling by building materials usage. The scientific contribution of the research is Analisis Satuan Material (ASM) development as a method for EE value of building materials calculation that will be recognized by stakeholders in Indonesia easyly. The research propose the EE value of building materials as part of green building criteria for energy assessment section. The information technology approach by EEC Software applications will be a practical contribution for participating in the mitigation of environmental impacts.
