In a feature article by Jennie Morton in this month's issue of Buildings Magazine, Dan Bailey of Sieben Energy Associates is quoted several times discussing the future of solar photovoltaics. The article, "The Next Wave of Solar", introduces thin-film solar cell technology, which makes it possible for solar cells to be incorporated into functional parts of a building. They no longer need to be accessories placed on top of or next to the structure.
Building integrated photovoltaics (BIPVs) are a growing trend. BIPVs seamlessly combine the solar cells with standard materials used in the building envelope—such as roofs, glass, or façade. Solar cells are no longer confined to the domain of building engineering; they increasingly appear in the context of building design and building architecture.
