既有公共建筑轻质屋面光伏一体化探索与应用

Exploration and Application of Existing Public Buildings Light Roof Integrated Photovoltaic

既有公共建筑中绝大多数屋顶存在屋面形式复杂、可利用有效面积小等问题,导致屋顶太阳能光伏系统安装面积小、安装困难。本文主要通过技贸大厦屋顶改造工程的成功案例,探索将具有隔热功能的轻质采光系统屋面和光伏系统结合使用的可行性、难点、解决方案等及在各种既有公共建筑屋顶上实现光伏建筑一体化、规模化的可行性。

there are complex roof forms and few effective area available problems in vast majority of existing public buildings, which causes small installation area and difficult installation condition in rooftop solar photovoltaic system. This article is based on successful case study of technology and trade building, explores combination feasibilities, difficulties and solutions of light roof lighting system plus heat insulation with photovoltaic systems. It realizes large-scale and integration of building with photovoltaic in all kinds of existing public buildings roof.
