Green Building Assessment Indicators Applicability

The practice of Green Building assessment system sets up a bridge between such considerations as public security, traffic, sanitation, long underscored in the past architecture design, and the perspective that agrees with ecology and sustainable development. In Taiwan, the practice of Green Building assessment system is still in its early stage. Many details in actual practice and the adaptability of various assessment indicators still await the setting up of related research bases. The thesis, therefore, chooses to look into those approved cases of Green Building so as to learn more about the adaptability of the nine indicators listed below. The thesis sets out to study those approved cases of Green Building found in the fiscal year 2004. The study consists of two parts. The first part aims to learn, through the details and data of the nine indicators, from each and every approved case and excellent case the applied methods of Green Building; and, from the data, the actual adaptability of the indicators. The second part seeks to know, through a class interval analysis by making use of the histogram, the spread of each indicator's designed values to provide a basis on which to offer suggestions to the assessment system of future Green Building. As we know, the Green Building assessment systems in advanced countries, such as United States' LEED (Leadership in Energy and Environmental Design), United Kingdom's BREEAM (BRE's Environmental Assessment Method) and Japan's CASBEE, adopt general assessment and rating system to differentiate among various cases of Green Building. The current assessment system used in Taiwan, on the other hand, assesses only the lowest assessment level. It cannot reveal the actual level of an approved case of Green BuildingAs regards applied methods for Green Building, the findings are as follows.1. Biodiversity IndicatorBiotope ranks first. Soil ecology ranks last.2. Greenery IndicatorThe percentage and density of sparse vegetation of trees and large broad-leaf trees effectively determine the level of this indicator.3. Soil Water Content IndicatorQ1 Soil Water Content of green land, grass trip, and grass swale areused most pervasively. The use of Q4 ground surface storageinfiltration design can effectively transcend the benchmarks of thepresent indicator.4. Energy Saving IndicatorWhen it comes to the Energy Saving Assessment Method ofAir-Conditioning System, chiller capacity design of ACsc/Acs revealsexcessive design.5. CO₂ Emission Reduction IndicatorThe using rates of different factors are close. Lightness factor (Wi),however, is the highest.6. Waste Reduction IndicatorThe primary methods are PIe and PIa.7. Indoor Environment IndicatorThe scores derive mainly from ventilation and air exchange. The rateof using green building materials when using interior materials remainsto be elevated.8. Water Resource IndicatorMassive water consumption is indicated. The rate of a need to adopt mitigation measures is too high.9. Sewage and Garbage Improvement IndicatorDaily-life mixed drainage into sewage disposal facilities and theclassification and recycling system of garbage resources rank highest.
