Implementation of Life Cycle Costing for a University Building Peter Kaming

Publisher : Indonesian Life Cycle Assessment Network (ILCAN)

Analysis of a design process is very important in controlling the initial costs and future costs in possession of an investment project. Therefore, it should be wise to perform a LCC analysis to determine the cost of any category contained in a building project. The analysis also provide information to see how much the total cost incurred by a development project from initial to the future cost by implementing BS ISO 15686 part 5: 2008. The purpose of this study is to identify the cost proportion and make long-term plans of a university building in term of life cycle costing in the area of Univeristy of Atma Jaya Yogyakarta (UAJY). Results of the study show that there are three groups that make up the LCC: the cost of development of the building, the operating costs, and the cost of maintenance and replacement. For a long-term plan the LCC for 25 years the percentage obtained as follows, initial development cost of Rp. 10,301,450,000 (43%), operational costs Rp. 11,085,000,000 (46%), maintenance and replacement costs Rp. 2.660.570.080 (11%).

Life Cycle Assessment (LCA) has been initiated in Thailand since the late 1990s with the first life cycle inventory (LCI) of the electricity grid mix and the offering of the first full graduate course. Since then it has come a long way through the development of the national LCI database and application in various research, industry as well as policy initiatives. LCA has been used extensively as an evaluation and decision tool in agri-food products, energy as well as many other sectors. Many graduate studies as well as research and industrial LCA projects have been performed. Related activities include the proliferation of carbon footprint labeling and application in green purchasing initiatives. Industry has been very actively participating in the carbon footprinting applications, some of them extending their interest to full LCAs for environmental performance evaluation and sustainability reporting. More recently, efforts have also been moving in the direction of looking at life cycle impact assessment methods from a Thailand perspective. Also, with interest in LCA from the policy making perspective, a capacity building effort has been initiated to train researchers in conducting LCA-related research on a sustained basis and ensure that Thailand keeps abreast of the international trends and discussions.

Environmental Impacts of Palm Oil Products: What can we learn from LCA? Cécile Bessou; Lénaïc Pardon

Quantifying the environmental impact of production systems has become a milestone for agricultural commodity chains. Life Cycle Assessment (LCA) is a unique ISO standardized methodology for estimating the environmental impact of human activities along a commodity chain. In the last decade, LCA has become the worldwide standard for environmental product declarations and the baseline model behind various GHG calculators and certifications (e.g. European Directive 2009; RSPO PalmGHG 2012). Various LCA on palm oil products have shown that the agricultural stage is a major contributor to most of the potential environmental impacts, including global warming, eutrophication and acidification for instance. This large contribution is due to combined important nitrogen (N) input levels in the field and low input levels at the mill and refinery stages. The agricultural stage remains a critical contributor even when the system boundary is extended to palm-based biofuel production. Focusing on global warming impact, main contributors are N-related GHG emissions in the plantation and methane emissions from palm oil mill effluent treatment. The impact from the plantation becomes overwhelming when forests or peatland areas are converted to palm plantations. Meanwhile, impact from palm oil mill effluent can be drastically reduced if the biogas is captured with electricity recovery. While nitrogen inputs are critical, LCA models still mostly rely on global emission factor. A better modeling of the nitrogen balance including a better accounting for soil processes would allow for a more accurate diagnosis of environmental impacts and control levers in plantation management.

Environmental Assessment of Motorcycle using a Life-Cycle Perspective Bertha Maya Sopha; Setiowati Setiowati; Sholeh Ma’mun

Transportation sector contributes as the second largest polluter of the air pollution in Indonesia. Of the transportation sector, road transport has generated 70% of the air pollution, 81% of which is attributable to motorcycles. The motorcycles are currently accounting for 79% of the total motor vehicles. It is predicted that the number of motorcycles will continue to grow at an annual rate of 9-26%. However, due to little attention to the motorcycle’s environmental impacts, this present study, therefore, aims to assess and report the environmental impacts of using motorcycles based on life-cycle perspective. Using a functional unit of one passenger per kilometer (pkm), resource consumption and emissions through the entire life-cycle of a motorcycle were estimated. The foreground Life Cycle Inventory (LCI) was compiled through observation, interview, and secondary data, while the background LCI was based on ecoinvent data v.2.0. Results show that the environmental impacts of the chosen function unit constitute Abiotic Resource Depletion Potential (ADP) of 0.515 g Sb-eq., Global Warming Potential (GWP) of 176 g CO2-eq, Human Toxicity Potential (HTP) of 1.1 g 1.4-DCB-eq, and Acidification Potential (AP) of 0.544 g SO2-eq, respectively. Operation (usage stage) of the motorcycle has been the most contributor to GWP and AP, while manufacturing stage has been the most contributor to HTP. Potential interventions related to the manufacturing process, fuel, and usage of the motorcycle to reduce the environmental impacts are also discussed.

Evaluation of Different Aquaculture Feed Ingredients in Indonesia Using Life Cycle Assessment Patrik John Gustav Henriksson; Chadag Vishnumurthy Mohan; Michael John Phillips

Indonesia’s aquaculture industry has grown by almost 25% annually over the last five years, an achievement enabled through the increased use of commercial aquaculture feeds, made from agricultural, capture fisheries and livestock resources. The reliance of aquaculture on capture fisheries has, however, attracted criticism, as has the land use consequences of imported Brazilian soybeans. Sourcing more sustainable resources has thus become part of maintaining a good environmental image and to secure long-term growth. In the present study we applied LCA to a number of feed ingredients used by the Indonesian aquaculture industry, including local fishmeal, rice and maize, as well as imported soybean, wheat and livestock byproduct meal (BPM). The impact categories global warming, acidification, eutrophication, land occupation and freshwater consumption were evaluated. Shrimp byproduct meal was generally associated with the largest emissions, followed by poultry byproduct meal. Wheat bran from Australia was the agricultural product with the largest acidification impacts, while rice bran had largest freshwater requirements. Overall, however, a shift is needed away from the overexploited local fish stocks towards alternative substitutes.
