According to the previous inventory report of Taoyuan county greenhouse gases (GHG) emission, the residential/commercial sector takes 16% of total GHG emission. After evaluating the emission reduction capacity of each sector, Taoyuan County EPB selected the residential/commercial sector as one of the main carbon reduction targets in 2010 and guide them this initial implementation plan. The plan is designed for 10 months of execution period. The plan goal is to form the professional group to provide the consultation for energy conservation improvement. This group mainly works on the facility energy saving diagnosis, guidance, improvement to reduce the electric power waste and CO2 emission. In addition, the group also assists in promoting energy saving label equipments and products, spreading the usage of high efficiency products and increasing the energy efficiency. Through the various promotion and performance award activities, it is expected to enhance the residents’ awareness and concept of carbon reduction and anti-warming. The plan annually accepts 31 guidance applications from the residential/commercial sector enterprises, and implements the on-site visiting guidance orderly; accomplishes those 31 energy conservation and carbon reduction guidance and the improvement effectiveness evaluation. Based on the suggested items by the guidance group, it is estimated the total energy saving is up to 11,869,925 degrees annually and the carbon reduction is up to 7,394 tons. Furthermore, according to the suggested improvement facilities, the improvement in lighting reaches 3,750 tons of carbon emission reduction as the highest, and followed by 3,446 ton of carbon reduction in air condition system. Considering the cost effectiveness, the improvement cost of 31 enterprises is approximately NT$44.79 million while the annual energy saving amount is counted over NT$41.95 million. Among the 31 guidance enterprises, it is estimated 10 of them could achieve over 100 tons of carbon reduction after the improvement. Therefore, the plan, targeting the large-scale residential buildings and stores with the practical facilities improvements, would be anticipated the significant result of carbon reduction. In addition, choosing 8 enterprises among the various public and enterprises including department stores, warehouses, hospitals, restaurants/hotels, residential buildings and office buildings and etc, the plan would evaluate the high efficiency of energy saving and self-execution improvement projects that could be accomplished by June, 2011, and then implement the inventory of GHG emission quantity and provide the guidance. Through the inventory of GHG emission, it helps to realize the GHG emission structure. The main GHG emission of residential/commercial sector is the electricity usage. The electricity usage includes lighting and air conditioning systems. Therefore, this project’s focus will be on the lighting revolution and the improvement of air condition system. For the enterprise which has completed improvement, the plan has been provide the partial project financial support of total NT$237,563. According to the evaluation of the cost effectiveness of the improvement, this year a.mart Jian (Taoyuan store) invested the highest amount of approximate NT$1.38 million on the improvement, annual energy saving 2,038,890 degrees, 1,248 tons of carbon reduction, and the annual improvement effectiveness of NT$6,116,670. Followed by The Yorker De’luxe Motel, it invested NT$110 thousand on the improvement projects, which achieves 12,420 m3 of annual gas usage saving, 26 tons of CO2 emission reduction, and NT$198,720 per year of improvement effectiveness. The third is 3 residential buildings. The lighting facilities improvement reduces the carbon emission by 22 to 27 tons. For the production of media promotion, the plan uses the video record, promotion booklet about the carbon reduction result of residential/commercial sector which includes the carbon reduction experience and the cost effectiveness of the demonstrated enterprises. It is expected that the residents will follow and implement self-improvement energy saving annually.
