| Abstract | In this study, the energy performance ofthe Shangri-La EDSA Plaza shopping mall at its present level of occupancy was assessed, general recommendations to improve the energy utilization efficiency proposed, and the most economically attractive CHP scheme that would best match the projected electricity and comfort cooling needs of the building determined. An energy audit of the building was conducted and quantification of savings on practical energy conservation opportunities was made, where possible. Full occupancy load profiles were established from which the sizing of the cogeneration system was based. In assessing the most profitable cogeneration scheme, the Total Energy Management software package was used. From the derived load demand patterns of electricity and cooling utility, equipment unit capacity costs, and other financial parameters which characterize the prevailing energy resource condition in the Philippines, the optimal CHP multiplant facilities leading to minimum total annual cost was derived using the linear programming model. The cogeneration scheme that would yield the highest IRR (66.2%) is a grid-dependent system combined with diesel generator set (4,200 kW), an absorption chiller (532 RT) and a cold storage tank (5,765 RT·h and a 640 RT compression chiller), and an auxiliary boiler (3 T/h). Investment required is $3.4 Million and the total annual cost is $3.01 Million. Another benefit is the reduction in C02 emission by 2,990 T/year corresponding to the fuel savings of 1.4 Million liters. An external factor that could greatly influence the profitability of the cogeneration project is the price ratio. In the Philippines cogeneration project is very attractive since the price ratio is about 4.5. But a price ratio of 2.15 (using tariff and fuel costs for Thailand) would drastically reduce profitability of CHP. Other significant sensitivity factors which are critical to the IRR include: (1) lending rate, initially taken as 15%, which when increased or decreased by 60% to reflect soft loan rate (6%) and commercial bank rate (24%), will improve or reduce the IRR by 25%, and (2) capacity cost, which has similar impact on IRR as in (1) if the capacity cost of the project is either decreased or increased by 20%. Evidently, going into cogeneration is a viable option. And the key to the acceptance of this technology by the private sector is through information dissemination. The shopping mall chosen for this study for its part may pursue the project on the condition that energy prices do not change significantly over the lifespan of the project. |
