Abstract

The aim of this research was to study the energy conservation guidelines under the Energy Conservation Promotion Act. As determining appropriate energy-saving measures and studying the cost-effectiveness of investment in economics for each measure from a case study of the Fortune Town Shopping Center building in Bangkok. The results showed that replacing the sprinkler heads at the 4 cooling towers with 500 TR can increase cooling efficiency and reduce energy consumption in the cooling system. Using electric energy 15,695.00 kWh/year (save electricity 187,785.00 baht/year) with IRR 86.00% payback 2.95 years. Replacing the Package Water-Cooled air conditioner can improve the energy efficiency of the air conditioner. But it can't pay back and save money. This is because the energy cost from the new machine has higher energy consumption compared to the old machine. And investment for the meter from changing fluorescent lamps to LED lamps, we found that both the plaza and IT mall buildings by the plaza can reduce electricity consumption up to 100,552.54 kWh/year (save electricity cost 407,237.77 baht/year) with NPV value got from energy-saving measures equal to 1,584,424.86 baht, with IRR value of 86.10%, payback of 1.11 years. As for the IT Mall building, it can reduce electricity consumption by 70,293.74 kWh / year (save electricity 284,689.66 baht/year), with the NPV value got from the energy-saving measure equal to 1,170,212.30 baht, IRR 109.64%, payback 0.89 years.
