Materials' EE is an issue in green building which refers to energy released in building- lifecycle of a material usage. Therefore, EE value becomes very important in measuring how much energy will be consumed and how environment can be damaged, since the planning phase of the building. The materials' EE calculation is called Material Unit Analysis (MUA). It was developed base on Work Unit Price Analysis or AHSP method as a construction material calculation method in Indonesia. Application design of EE calculation for building materials software use the flowchart as programming. The main programmes are software and simulation section of EE calculation. Software section display some function are ; the materials' EE inventory data, unit conversion and input new materials which is not in EE inventory data. The simulation section could show the materials' EE calculation results in three display, are in: each material unit, building components or total building. Hopefully, materials' of EE calculation software application will ease the calculation system. The designers are willing to do the EE value calculation, and using it as an environmental consideration in the design decisions. Keywords - Application, Building Material, Calculation, Design, Embodied Energy I. INTRODUCTION This paper will decsribe application design and development the Embodied Energy (EE) Calculation for building material. EE calculation software application could make the materials' EE calculation tool usage easier. It will be encourage designers to calculate EE material value for their building planning. It is a mitigation efforts for use no harm materials for environment in the future. Development activities were consumed a large of energy and contribute Emission Carbon (EC) increasing. It mean would effect to environment temperature increasing which is called greenhouse effect. Most country in the world start to use Clean Develoment Mechanism (CDM) implementation as global agreement to reduce EC and make the world greener [1,2]. Energy policy for building concern to manage the energy efficient, are ; 1) Energy efficient of Building Planning, 2) Integration of City Planning. Both of all were support the implementation as energy efficient building standard and environment friendly [2]. An energy mitigation of building could use technology aspect as an approach to implement energy mitigation through EE material calculation of building. The application was created as application software and it developed base on Analisis Harga Satuan Pekerjaan (AHSP) method developing. Materials' EE value calculation has developed as a tool to count the EE material value of the object. It promote for stakeholder to involve as their role and responsibility to early energy mitigation. [3]. Material measurement of building would not figure out of all building energy consumption, but it would represent for most part of a large the building energy consumption [4]. 1.1 Embodied Energy Analysis The energy that accompany its activities in each or total phase of lifecycle building is called Embodied Energy (EE). EE in buildings represents the non-renewable energy consumed in the acquisition of raw materials, their processing, manufacturing, transportation to site, and construction. EE has direct energy that used to transport building products to the site, and then to construct the building; and indirect energy that used to acquire, process, and manufacture the building materials, including any transportation related to these activities [5]. EE in planning phase will cover all activities for materials building procurement in pre- construction phase or called as craddle to the gate [6]. Materials' EE value was resulted through EE material calculation process. Most in Indonesia, construction work planning use AHSP method which is issued by Badan Standarisasi Nasional (BSN). AHSP or Work Unit Price Analysis (WUPA) have some component of construction work, are : materials, labour and equipment. WUPA will breakdown all component of construction work as RESEARCH ARTICLE OPEN ACCESS
