520 _aAfter a long embargo period and a longer centralized administration of economy with its subsidized price mechanism, the economy of Viet Nam has started to develop strongly. Hochiminh city is a key economy area of the country . Industry, which plays an most important role in the economy of the city, is the biggest energy consumer with a continuously increasing growth rate. Outdated and second hand production equipment have lead to high increases in energy cost of industrial products. It seems timely to estimate the energy saving potential of industry. This is one of the key steps in the consideration of re-investment and renovation and may lead to reduction of investment or operation costs. In this study, three industrial sub-sectors including textile, food and non-metal industries have been considered due to their large contribution in gross industrial products, share in total industrial energy consumption and energy intensity. Three factories for each sub-sector were selected for energy audits. The energy saving opportunities could be classified as short , medium and long term based on investment requirement and pay back period. From the energy audit results, and through extrapolation, we estimate the saving opportunities of textile industry to be 1.8% using short term measures (mostly housekeeping, combustion tuning, blowdown control, insulation improvement) and 38% using medium term measures (such as combustion efficiency controller, flue gas recovery, heat recovery from hot effluents, heat recovery from condensate, insulation of bare pipe). In addition to these measures, another 6.9% saving can be expected by opting for long term options such as replacement of boilers and furnaces. In food industry, the saving opportunities could be 3% using short terms measures, 45.5% using medium and 8.5% using long term measures. Finally, the saving opportunities of non metal industry could be 0.1 % using short term measures, 0.7% using medium term measures and 11.4% using long term measures. These energy savings would lead to overall sub-sectoral reduction of 2% using short term measures for textile and food industry and 1 % for non metal industry. With medium term measures, the sub-sectoral energy consumption of textile would reduce by 31 %, that of food industry could reduce by 22% and that of non metal industry could reduce by 15%. The long term measures would to reduce 10% of sub-sectoral energy consumption of textile, 2% of food and 1 % of non metal industries.
