摘要

全球性溫暖化所產生的高溫及氣候異變造成極地冰源融化現象，其速度遠遠超出科學家們的預期，因氣候異常的現象所造成之重大災情也較往年來得頻繁，每當災情不斷發生時，各國政府便更加的關注及檢討其生成的原因，多數學者及科學家們將災害的主因指向全球暖化的問題，因此，自1997年簽訂「京都議定書」至今，各締約國皆已其議定書內約定溫室氣體排放減量展開各種可能的因應對策，著手進行各項研究，以其能設法降低溫室氣體排放量及減緩地球暖化速度。

建築界在能源逐漸耗竭、原物料價格持續飆漲及環保節能減碳等約束之多重壓力下，也正積極的關注及推動「綠建築」政策，因此內政部營建署透過「營建白皮書」正式宣布將全面積極的推動綠建築政策，及建立「綠建築標章」制度；在「建築技術規則」建築設計施工篇增訂第十七章綠建築專章，自民國94年1月1日起也逐步實施。再再顯示政府積極投入「綠建築」政策的決心及響應全球節能減碳的目標。

本研究針對台北市南京東路四段及五段之老舊建築物外殼更新，進行可行性之分析探討，以永續的觀點提出外殼更新改善的可行方案，同時藉由研究及實際案例模擬操作，研擬可再生循環利用的節能建築物外殼系統，除了可達到節能減碳及減少廢棄物的目的外，亦可提升街道環境的觀瞻及降低熱島效應與洪泛的發生，在此，本研究將依其節能減碳及高性能建築的觀點，提出外殼更新、再生循環利用的系統構法及降低外殼更新完成後之使用維護管理成本，以達到真正落實節能減碳的環保目標。

研究成果如下：

1.建築外殼更新系統構法之建立：
在外殼系統構法之運用上以不造成二次環境破壞為前提下，採用保留原有外牆面材為原則，僅針對外牆劣化及污染部分進行修繕及施作防水後，再行施作透氣型之複層牆。依開口比例將單元模組化為1：1、1：2及1：3三種型式之格子遮陽單元系統。
2. 建築屋頂更新構造模組之設計：
於RC平屋頂構造上採用施工便利性佳且同時達到較佳的隔熱性能之通風型複層樓版，每一單元外淨尺寸182X182CM(內淨尺寸180X180CM)之活動式架高樓版進行模組化的單元組合設計。

High temperature and climate abnormal change arising from the global warming have led to melting of polar ice sheets, which speed has far exceeded scientists’ expectations. The major disasters due to climate abnormality are becoming more frequent than in previous years. When disasters happen continuously, governments around the world will pay more attention to and investigate their causes of occurrence. Most scholars and scientists ascribe the major causes of the disasters to the problem of global warming. Therefore, since the signing of the Kyoto Protocol in 1997, all its contracting states have carried out every possible solution and started working on various researches for their greenhouse gas emission reduction as agreed in the protocol, with the hope of trying to reducing the greenhouse gas emissions and slowing down the speed of global warming.

Under the multiple pressures concerning gradual exhaustion of energy resources, continuously soaring prices in raw materials, and the constraints on environment protection, energy saving, carbon reduction and other aspects, the architecture circle is also actively concerning about and promoting the “Green Building” policy. Therefore, through the “White Paper on Sustainability – Building Design & Construction”, the Construction and Planning Agency, Minister Of Interior has formally announced to fully and positively advance the “Green Building” policy and establish the “Green Building Label” system, and added the special chapter 17 on green buildings to the building design & construction section under the “Building Technical Regulations”, which has been gradually implemented since January 1, 2005. This again shows the government’s determination of positively engaging in the “Green Building” policy and its response to the goals of global energy saving and carbon reduction.

This study conducts a feasibility analysis on the renewal of the old building envelopes at the Sec. 4 & Sec. 5 Nanjing East Road in Taipei City, puts forward a feasible scheme on the envelope renewal and improvement in the perspective of sustainability, and works out a renewable recycling energy-saving building envelope system by application research, which can not only realize the goals of saving energy and reducing carbon and wastes, but also can improve the appearance of the street environment and reduce the occurrence of heat island effect. Thus, this paper will, from its perspectives of energy saving, carbon reduction and high-performance building, propose systematic structuke on the envelope renewal and renewable recycling, and to reduce the maintenance management costs to be used after the completion of the envelope renewal, in order to achieve the environmental protection goals of actually implementing energy saving and carbon reduction.

This contributions of this study are:

1. Establish a systemic structure of the renewal of building envelope :
Under the premise of no secondary damage is caused to the environment in the application of the envelope system formation, and based on the principle of retaining the original outer wall surface materials, after conducting repair and water proof treatments only for the outer wall’s degraded and polluted parts, make the wall into air-permeable multi-layer type. Modularize the units into the three types of grid sunshade unit systems of 1：1, 1：2 and 1：3 according to the opening proportions.
2. Design a ventilated multi-layer plates of roof system :
In RC flat roof construction, use ventilated multi-layer plates which are very convenient in construction and can realize better heat-shielding performance. The movable high-hung plate with an outer net size of 182 x 182cm (inner net size: 180 x 180cm) of each unit is undergone modular unit combination design.
