Using the Knowledge Portal

Q: What is the content of the Knowledge Portal?
The content within the Knowledge Portal comprises:

  • All CIBSE publications. CIBSE members are given access free access to full texts as electronic (PDF) files, where available, free of charge. Besides these normal CIBSE books there are a small number of CIBSE Briefings, Bulletins and similar documents included. CIBSE books can also be bought as hard copy by members at preferential pricing. Non-members must buy hard copy books or priced pdfs wherever available.
  • A large number of papers presented at the various CIBSE Technical Symposiums. These have all been peer reviewed as part of the submission requirements for the Symposium and are made available to all users free of charge.
  • A large number of titles from a range of other leading publishers that compliment CIBSE own published knowledge. These are only available to purchase as hard copy at present - but with CIBSE members generally benefiting from a generous member's discount.

All entries within the Knowledge Portal can be browsed by title or identified by using text search functionality.

Q: Am I allowed to print/save/cut and paste from documents?
The Knowledge Portal is designed to allow CIBSE Members ready access to CIBSE publications for their own use. PDFs can be downloaded onto member’s own devices. For details see the 'CIBSE copyright' section of the 'Fair Use Policy' webpage.

All usage of the Knowledge Portal is subject to this Fair Use Policy. It is incumbent on CIBSE members to ensure that they do not abuse that benefit nor make their membership details available permitting abuse by a third party. Excessive or inappropriate use by valid users and other breaches of CIBSE copyright (without express permission) constitute abuse of this benefit.

Q: About PDF files
PDF files downloaded from the KP are stored on the users own equipment and may be large files. PDF files will benefit from enhance functionality built into their own document viewer (eg Adobe Reader) such as search, cut-and-paste etc. Note: PDFs downloaded from the Knowledge Portal are watermarked  to remind members of their responsibilities and CIBSE's ownership of the content. Responsibility to ensure downloaded documents are not abused nor CIBSE copyright infringed lies with the member making the download.

Q: What can a non-member gain from the Knowledge Portal?
Non-members of CIBSE can use the Knowledge Portal to search CIBSE publications and other CIBSE material made available of the site and selected documents from other publishers - selected to be relevant to building services and to compliment CIBSE's own knowledge. Many titles and titles are free to all users, including 100's of Technical Symposium papers. However, this does not permit online access to document texts of priced documents, as these are only availlable to CIBSE Members. Non-members can purchase these documents though the Knowledge Portal (or choose to join CIBSE).

Q: Can I copy and paste from a pdf document into my own reports etc?
Most of the PDFs that CIBSE supply do allow you to copy text of the PDF. To do this, you highlight the chosen area and right click to choose “copy” and then, moving to your document, right click in the area chosen to paste the text in, clicking on “paste”. Rules relating to copying content such as cut-and-paste are described in the 'CIBSE copyright' section of the 'Fair Use Policy' webpage. Normal cut and paste options are that you should copy and paste no more than 10% of the document for referencing purposes (or one Chapter if that is greater) and you should note on your document where the text has come from (eg CIBSE Guide A)..

Copying a graphic image eg a diagram, flow chart or table, you can use the snapshot tool (camera icon) in the menu, then select the graphic which will automatically save it to your clipboard, then paste the graphic in as above.

Q: Can I copy a PDF document file?
No. Electronic images of CIBSE documents (PDFs) are made available to both CIBSE members and to persons buying them on the condition that they are for their own personal use only. They may not be duplicated or circulated in any form, for use by others, for re-sale or for any other purpose. Under exceptional circumstances CIBSE may give permission for a partial relaxation of this but requires a specific written request to CIBSE by emailing and express permission has to be obtained.

Q: I am not able to download the PDF, what do I do?
PDF files are readable using a number of applications but the Knowledge Portal is designed to function with Adobe Reader (version 7 or later). Adobe Reader can freely downloaded from the Adobe website. Additional functionality has been added to the files to aid usability - such as bookmarking - but this may not function in all document viewers. Further Technical queries should be addressed to or tel: 020 8772 3647.

Q: How do I suggest changes to existing publications or the need for new ones?
This is explained on the “knowledge generation” page under “propose an idea”. If you have a developed proposal you can use the more detailed forms which are also accessible from that page which can be found here
