建筑行业作为能耗以及污染相对较高的行业，首当其冲。
而如何在建筑建造和运营过程中降低能源和资源的消耗，同时又最小化其对周围生态环境甚至整个地球生态圈的影响，是许多建筑师探索和解决的方面。
可持续设计与绿色建筑概念的提出，无疑是为了应对和解决这一问题。
在绿色建筑评价标准中，提出了绿色建筑的定义，即在全寿命期内，最大限度地节约资源（节能、节地、节水、节材）、保护环境、减少污染、为人们提供健康、适用和高效的使用空间，与自然和谐共生的建筑。
从绿色建筑的定义上，可以看出绿色建筑评价标准的核心内容是在保证健康舒适人居环境的前提下，减少能源资源利用，最小化环境影响的同时为环境保护作出贡献。

Research Plan1。
Present research related to research planMy present research mainly focuses on the late transition metal catalysts for olefin polymerization and coordination polymerization of polar vinyl monomers. A family of new cationic Pd（II) and Ni（II) complex catalysts reported shows good activity for polymerization of polar vinyl monomers and olefins. The easily varied steric and electronic properties of ligands are an important feature of the late transition metal complex catalysts。
The samples include [bis(2—biphenylylimino）acenaphthene］dichloronickel；［bis(1—naphthylimino)acenaphthene］dichloronickel;［（N-1-naphthy- limino-N’-2,6—isopropylphenylimino)acenaph-thene]dichloronickel; bis-[(N-2,6—diisopropyl phenylimino）—2-oxy-1—naphthylmethylene]nickel；bis[(N—2—methylphenylimino)—2-oxy-1—naphthyl—methylene］nickel，etc. The relationship between the structure of ligands and the activity of catalysts is the most important part in my present research。
