IHS BRE Press Building-integrated Photovoltaic Systems IP11/12

Learn about the challenges and opportunities that manufacturers and specifiers face in using BIPV rather than bolt-on BAPV systems. Information on BIPV products currently available and some of their typical applications is included. Author: S Pester Publish Date: 4/20/2012 ISBN: 978-1-84806-263-4 Abstract: The UK government’s feed-in tariff (FIT) incentives, building regulations and planning requirements have been driving the installation of building-applied photovoltaic (BAPV) systems in the UK. With the currently prevailing low interest rates, the FITs have transformed PV installations into a serious proposition for investors and they can also be a cost-effective way to achieve compliance with the local and national regulations. On the other hand, the uptake of building-integrated photovoltaics (BIPV) has been relatively low to date. This may be due to perceptions of high cost, questions over durability and maintenance, uncertainty concerning energy yield and ease of use for designers. Some of these perceptions may be valid and some based on misunderstandings, but what is clear is that the product manufacturers must address all concerns in an open and transparent way if they are to get their products specified in building projects. The aim of this Information Paper is to help to close the gap between building designers and manufacturers of BIPV products. Specifiers will find useful information on products currently available and some typical applications, whilst manufacturers may benefit from the feedback obtained directly from potential users of the technology. Information has been gathered from three main sources: a survey of products currently on the market; a survey of architects; and two stakeholder workshops held at BRE in 2010 and 2011.
