Until September 2013, 1150 cases in total passed the requirements for green building, of which only 132 obtained silver level marks and above. Related research shows that the cost of a green building is the main consideration of developers. However, is the cost of constructing a green building under the government’s incentives program really too high to reach? What is the cost of upgrading silver level mark to gold level mark? 　　This paper takes 8 mid and high-rise dwelling places in the metropolitan district of Taipei, to upgrade them from their current silver level mark to gold level mark and try to calculate the cost of every upgrading method. Materials with better heat insulation property to reduce heat conductivity are considered. The fixed energy consumption equipment adopts energy-saving hot water pipes and permeable pavement design. Moreover, it makes use of a shower bathtub and fifty-fifty proportion of shower and bath to avoid extra cost. Fallen leaves compost treatment and recycling measures are implemented. Floor construction is enhanced. Tree type (shrub) is changed to the trees capable of attracting birds and butterflies or Taiwan native tree species. Improvement is done on the usage rate of materials, storage permeation pool or storage permeation space design, central collection facilities for food waste system and regular cleaning of the facilities through outsourcing. The fixed energy consumption equipment incorporates an energy-saving gas stove and energy-saving water heater. In addition, it increases the airtight level of windows and chooses glass with better translucency as well as better heat insulation property. An additional NTD 0.22~327.99 is needed for every 3.3 square meters for the above upgrading methods. The maximum cost of each 3.3 square meters for the 8 cases that are to be upgraded from silver to gold on the average is NTD 820, which shows that the cost of constructing green buildings is not as high as mentioned in the market. Through proper methods or planning & design, it can reach the standards required to upgrade from silver to gold level mark. In addition, with the government’s incentives program forconstructing green buildings, it cannot only make the entire planning more effective with benefits outweighingthe needed cost, but also make Taiwan move further towards an environment friendly living space with sustainable development.
