摘要：有鑑於能源危機不斷浮現，前瞻建築概念便在於善用再生能源科技與節能建材發展『零耗能住宅』（ZEH），類似的策略亦可用來發展低耗能交通工具。而為求早日實現上述目標並緩解能源需求的迫切性，積極研發具備自動日照調節能力之『智慧型窗戶』實為重要課題。電致色變窗戶可藉由改變外加電位可逆地調控入射光線之穿透率，進而調節日照所引起的室內加熱現象，有效地減少空調系統運轉的負載與照明耗電量。因此電致色變窗戶無論在住商建築、人工氣候室、汽車、火車、船舶、航空器等大眾運輸工具皆極富應用價值與商業潛力。故本計畫擬以兩年時程（民國96-97年）研發應用奈米結構鐵氰化銦（InHCF）為輔助電極之新型高節能效率電致色變窗戶系統。使用InHCF擬透明輔助電極時，工作電極不必預先著色與極化，可減少窗戶元件封裝難度並有效地提升系統操作穩定性；另一方面，InHCF為相對新穎之材料，所開發出之節能窗戶系統將極富專利優勢。96年度的主要研發重點在於以InHCF輔助電極搭配過渡金屬氧化物、過渡金屬氰化錯合物、有機聯啶分子及導電高分子等四大類型之高著色效率工作電極材料以及適當的固態高分子電解質，平行開發多種電致色變系統之小型先導元件，以利後續節能窗戶系統篩選與開發。
Abstract: By considering the continuous emergence of global energy crisis, several advanced building technologies aim to develop a “zero-energy home” (ZEH) based on renewable energy devices and energy-saving materials. The same strategy can be used to develop low-energy transportation. In order to realize the above goals in the near future and to relieve the urgent need of energy, R&D in “smart windows” with the capability of automatic daylighting control is of much importance. Electrochromic windows (ECWs) can modulate solar transmission reversibly by applying low dc bias and then control the interior solar heating. Hence, the energy or electricity required for air conditioning and lighting can be significantly reduced. As a consequence, ECWs are of great commercial value for the applications in ordinary housing, commercial buildings, greenhouses, automobiles, public transport, ships, aircrafts, and so on. Here we propose a two-year energy tech plan (2007-2008) to develop novel ECW systems with high energy-saving efficiency using a nanostructured indium hexacyanoferrate (InHCF) counter electrode. When using pseudo-transparent InHCF, the working electrode does not need precoloration and polarization during device assembly. Hence, the assembly process can be simplified, and the system stability can be enhanced correspondingly. Besides, the ECW systems developed by this plan will be advantageous for the patent application since InHCF is a relatively new material. In the first year (2007), we will focus on the parallel development of multiple pilot ECW systems by matching the nanostructured InHCF counter electrode with appropriate solid polymer electrolytes and high-coloration-efficiency working electrode materials, such as transition metal oxides, transition metal cyanides, organic bipyridines, and conducting polymers. The results will provide informative clues for high-energy-saving system screening and full-size window development in the next stage (2008).
