Building Materials and Building Envelope Performance
ASHRAE Technical Committee 4.4

Meeting Documents

Download documents from previous committee meetings below according to the appropriate society year. ASHRAE's society year begins on July 1 and ends June 30.

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.
