綠建築評估系統外觀意象指標之研究—以低層建築為例

A Research on Appearance Image-related Indicators of EEWH--A Case Study For Low-Floor Buildings

本研究為瞭解民眾對於綠建築外觀之認知與偏好，彙整生態建築因應環境及氣候之設計特色、並分析其與綠建築評估指標之差異。依降溫、遮陽、通風等環境策略，歸納出熱濕氣候建築常用之六個造型(屋頂挑高、干欄式樓板架高、外加遮陽、騎樓陽台、通風口和覆土設計)及七種材質(木、竹、石、泥土、磚、金屬和混凝土)進行外觀意象研究。本研究採用李克特10點量尺，利用問卷及電腦模擬不同材質方式，找出受測者對於外觀意象的偏好。結果顯示，熱溼氣候建築外觀造型與偏好之關係，以干欄式樓板挑高之偏好平均值5.67最高；外觀造型與接受程度之關係，以覆土設計與干欄式樓板挑高之偏好平均值5.58最高；在綠建築外觀是否“須”傳達出意象之結果，以南部地區之(非常)認同，及景觀領域之受測者百分比最高。本研究結果可提供臺灣綠建築評估系統(EEWH)擬訂外觀設計原則之指標，期望使評估制度更加完善。

The research aims to understand the public cognition and preference for green buildings appearance, to consolidate the design characteristics of ecological buildings in various environment and climates, and to analyze the difference of evaluation index between ecological buildings and green buildings.
The appearance image research is conducted for the six hot-humid region architecture types generalized from the environmental strategies (e.g. cooling, shading and ventilation) such as high-ceiling roof, elevated floors with rails, extra sun-shade, corridor veranda, ventilation vents, and earth-coverage, and for the seven building materials such as wood, bamboo, stones, earth, bricks, metal, and concrete. The research adopts the 10-point Likert scale along with the questionnaires and computer simulations to find out the participants’ preference for the building appearance. Results indicate that in terms of the preference for hot-humid region architecture types, elevated floors with rails ranks first with average preference of 5.67, and that in terms of the acceptance level, earth-coverage and elevated floors with rails rank top with average preference of 5.58. As for whether the appearance of green building ‘needs’ to indicate the preference results, the participants in south region and scenery spots agree the most.
