We are happy to be able to offer a free PDF copy of a major new IEA publication titled Transition to Sustainable Buildings -- Strategies and Opportunities to 2050, which would normally cost 80 Euro. If you are interested in receiving the PDF please respond to and we will then verify your membership and then send you an invitation to share the IEA document in our DropBox, where you will find the 23 MB document and the password. Please note that the IEA requires that the document should only be available to bona fide iiSBE members, so please do not pass this on to non-members.
