Lots of countries are developing programs which are expected to contribute to economic recovery and to become a key element in greening the economy. Underlined the need to strengthen life‐cycle analysis of buildings and looking at the health effects. Low carbon, low cost and healthy issues should be considered as priority. According to statistics, Construction industries around the world, nearly consumed 50% of the global energy, 50% of water resource, 40% of the raw material and 80% loss of agricultural land. Simultaneously, construction industries generate 50% of air pollution, 42% of greenhouse gases, 50% of water pollution, 48% of solid waste and 50% of the CFC compounds. Therefore, to rethink the negative impacts due to inappropriate architectural design and construction methods should be one of the most serious tasks of all related professions. Wood architecture usually represents as a high awareness on ecological materials in many developed countries. The design concepts of wood architecture are also considered as priority for most of architects. Not only their excellent performance on energy saved and carbon reduction, but also they can provide better indoor environmental quality that benefit human healthy. Wood is the best low-carbon green material. Comparing to the other materials, the dry method of wood construction facilitate significantly the construction. The purposes of this research are in one hand, to discuss the role of wooden houses in low carbon design by reviewing the global trends including material characteristics, design and construction methods. In other hand, to study the influencing factors of the durability and physical situations of wooden houses in Taiwan, such as human behaviors, climate condition and construction regulations by investigating the users’ feed back in different cases. Finally the basis considerations for local design will be concluded and proposed. The results display, the key factors of promoting the wooded houses in Taiwan are related to followings: the construction quality, design request, regular maintenance and material control. Most of them can be technically overcome and in fact, different systems or construction methods of wooden houses are feasible in Taiwan. As conventional opinion pronounced, hot and humid weather obstructs the development of wooded houses in Taiwan. On the contrary, according to the results and analysis of this research, wooden houses can be promoted as a true ecological housing type in Taiwan by studying more details regarding the micro-climate problems of different localities in the low carbon era.
