Tip: The following section can be edited by the webmaster as needed. It does not have to be about Whitepapers. You can edit that to be anything. To add, delete or reposition sections of the accordion, use the concentric arrows button in the editing toolbar at the top. When typing or inserting text into an accordion and there is more than one paragraph, you MUST use "shift + enter" between paragraphs. Be sure that you do not accidentally just use the "enter" key to separate the paragraphs. It will look OK but after you publish the page, the text after the 'enter' may no longer be editable.

Additional documents produced by the TC may be available for direct download or for purchase through the ASHRAE Bookstore, as noted below.

Please be aware that unlike symposium papers, seminar material is informal. This means that the content of these seminar presentations:
      • Has been inspected to ensure their content complies with ASHRAE policy regarding commercialism.
      • Has not been peer-reviewed in its technical respects. There may be disagreement with its content or conclusions.
      • Represents opinions of the individual presenter, not of either ASHRAE or our technical committee. If you have questions regarding the seminar material itself, please contact the presenter directly. But if you have questions about our program activities or if you have suggestions for future seminars that would help you meet your goals, contact us through the Chair of our Program Subcommittee.
