摘要

本研究以台中地區選定二棟學校校舍作為本研究ENVLOAD的分析對象，以屋頂結構材料及立面開窗隔熱效能之現況條件下作一比較分析。
經由程式計算發現兩棟校舍原有之屋頂構造平均熱傳透率Uar及窗面日射取得量基準值AWSGs均不符合節能法規標準。爾後兩棟校舍各設定三種改善方案，其中以方案三(包括更新屋頂隔熱構材及開窗增設外遮陽)能符合最新法規要求，其程式計算之結果顯示：
1. A建築以方案三屋頂局部更新構材其Uar =0.97 W/ (㎡.K)；增設外遮陽其AWSGs =194.91kWh/(㎡.yr)，均能符合節能法規之Uar及AWSGs兩項標準。2. B建築以方案三屋頂更新構材其Uar =0.77 W/ (㎡.K)；增設外遮陽其AWSGs =197.81kWh/(㎡.yr)，均能符合節能法規之Uar及AWSGs兩項標準。本研究依相關分析結果所顯示之最佳方案進行相關建築外表構造材料降溫節能各項改善措施，並期望所得之數值，及建物改善方案能對相關之研究及未來學校類外殼節能措施設計上之發展有助益。

The research was conducted to study the heat insulation/transmittance efficiency of the 2 selected school buildings in the Taichung area with the use of ENVLOAD computer program which was recently developed in the construction industry to study the energy-related issues for buildings in Taiwan. The study was carried out also to analyze energy consumption efficiency between the selected schools with parameters revealing the structural material used and facial opening pattern/layout of the building.
The results of the computer analysis using ENLOAD program for the studied school buildings indicated that both the Uar (average thermal transmittance) of the roof top and ASWG (average window solar gain) of the building façade failed to meet the current code requirement for theenergy-related criteria. As part of the study, 3 improvement options were developed and re-analyzed to exhibit that Option III significantly modify both buildings to satisfy the current building code regarding heat insulation/transmittance efficiency, which include replacement of the floor material used on the roof top and addition of a shade canopy along both sides of the building façade.
The results of the study provide useful information for the school buildings to choose the most effective measure for reducing the solar energy transmittance and heat absorption, which in turn increases the energy conservation efficiency of the buildings, especially when using air conditioning in the summer time. In addition, the results of the study also provide useful reference for similar future projects for schools buildings in central Taiwan.
