【 摘 要 】

50% of office building electricity consumption comes from air conditioning system. For the past years, researches have been focusing on air conditioning system parts, rather than the distribution of air to the space in order to reduce energy consumption. Thus, upgrading old air handling unit (AHU) is needed in order for old building to save energy. Therefore, this research provides a view of the importance to save energy for small office building with old AHU. Survey is done to 110 respondents that familiar with small office building. A prototype of small office building (4 rooms) with automatic damper equip with movement sensor in each room is developed based from the survey result. This system controls flow of cool air to each room based on occupant existence. Flowrate to each room, power consumption, and rough calculation for the cost of electricity for a month is determined. Based from the survey, 95% of respondents agree that implementation of automatic damper system is urgent and important for energy saving. Supplying air to only one room for 8 hours for the whole month, when three other room is vacant, with reduced fan speed, has significant result to the power consumption of the building.
