Abstract

This independent study is aimed to assess the building by using evaluation criteria for Thai green building (TREES) including the information required for the assessment. This information makes us aware of important information used in calculating the score when applying evaluation criteria to assess Thai green building (TREES) for energetic and environmental sustainability. Data was collected from the real case study at the real place i.e., Central Festival Shopping Mall, Chiang Mai. The method conducted was the interview. This method was done by conducting the interview on the people involved both premises and system staff. Then, the consideration was made in order to choose alternative approaches to improve in the way of economic engineering and value engineering to be a guideline for making a decision. The study found that the TREES criteria were used in to evaluate because it could match the policy of the executive in order to improve the image of the building. It was also designed to be environmentally friendly with a relatively high score in the system as well. According to the evaluation in the energy and atmosphere sector, the score came out to be highest among 8 the sectors. The sector that got the lowest score was the construction materials and resources because of the time limit in the construction, so the score could be obtained only by using local materials. The other sub-sectors were divided into two areas: policy specification and the improvement that have an effect on energy cost reduction. Decrease in cost of energy and improvement found that the policy should define the category of the construction materials and resources from the stage of design. It is suitable for the construction that will occur in the future. The improvement that affects in cost reduction is in the category of innovation. This category will be able to score a lot further since the building in this case study provides a clear roadmap in terms of innovation. The improvement should be done efficiently and it was found that the possibility of getting the highest score was the category of energy and climate due to the high proportion. The building was being prepared starting from the step of design. As a result, energy simulation program using criterion scores could get standard score. The second category was the building management which could be easily scored. Although the proportion is not much, it is the intent of the owner of the building in environmental conservation. This independent study helped assess and can be used to guide the development and management of buildings to comply with the criterion of building a sustainable energy and environment in Thailand (TREES). Guidelines for building improvements to enhance capacity of the building will enable the awareness of the importance of the sustainable green building. It is also a good role model for building project for the society in the future.
