Question 2 [50 Points]: Table 1: platinum, Alpha and Deluxe Legend 2017 2018 2019 Sales (US$) Platinum Alpha Deluxe a. Correct the mistakes in the provided figure (15 points) b. Point all the negative point in the below abstract (35 points) Abstract- Feasibility analysis has been performed to find the financially optimum green building label for buildings in Thailand conforming to the Thailand's green building standard (Thai's Rating of Energy and Environmental Sustainability for New Construction and Major Renovation, TREES-NC). Three sample buildings comprising an office building (4 floors, 1, m2), a school building (6 floors, 6 m2), and a hospital building (3 floors, 6, m2) were used in this study. To achieve each level of the green label (i.e., certified, silver, gold, and platinum), 4 groups of green measures according to the 8 topics in the standard were assumed to be implemented to earn credits in the following order: measures with no investment & provide benefits, measures with no investment & no benefits, measures with investment & provide benefits, and measures with investment & no benefits. The EnergyPlus software was used to evaluate the energy savings from the measures in the Energy and Atmosphere topic. It was found that both silver and gold labels were financially feasible. At those levels, energy and water savings were within a range of % and %, respectively. The investment would be % higher than that of the baseline building. The payback period was found to be within a range of years which was the shortest compared with the other labels. The net present value (NPV) and the internal rate of return (IRR) were found to be within a range of 108,486, Baht and %, respectively, which were the highest compared with the other
