The Living Building Challenge Compliance Details are reviewed for updates on a quarterly basis. Updates may be needed to reflect new Clarifications and Exceptions, to add clarifying text, tables or graphics, and make other amendments or additions that improve the clarity and content of the Manual. When updates are made, they are published in this Program Manual in January, April, July, and/or October of each year, at which time the Manual cover page is date stamped with the latest revision. See Previous Versions of the Program Manual in the Table of Contents for a link to download PDFs of previous versions.
At each update, a summary of the substantive changes is provided in the following sections. Summaries of changes for the previous year will be retained here. To get copies of early summaries, contact lbc.support@living-future.org.
A summary of changes between LBC 4.0 and LBC 4.1 can be found under Program Summary of Changes here.
