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.


Other Publications

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


ASHRAE members have free access to research project final reports. Non-ASHRAE members can purchase research reports for $30 per article from the ASHRAE Bookstore found at this link.

TC 4.10 - Indoor Environmental Modeling

The transport of potential infectious agents from human bodies under the impact of ventilation airflow is not well understood. Existing studies are largely based on simple scenarios and thus the conclusions have limitations. For general health requirement as well as protecting susceptible individuals when there may be infected persons as contaminant sources, it is important to design the ventilation system carefully to avoid the spread of infectious agents. Besides, the SARS epidemic in 2003 and current concerns about the risk of an avian influenza (H5N1) pandemic, have made this study timely.

The results can help ASHRAE members and other professionals to better analyze and design healthier and safer indoor environments, especially for ventilation design. The commonly used ventilation modes in actual engineering are evaluated for their performances on inter-personal contaminant transport control. Results derived from this study would provide useful information to better understand the possible link between ventilation and contaminant transmission. The efficiency on controlling person-to-person contaminant transport and economical energy using should be balanced for actual application. Thus a guide on proper ventilation design would also benefit engineering practice.
