TC 8.12 Research Strategy
Our technical committee has been active in promoting research to improve dehumidification and drying in general, as well as improving desiccant materials and equipment. If you see a research need which would help advance the state of the art in these areas, we are eager to hear about it through our research committee Chair.
Research Projects In Progress
At present there are no research projects in progress, but several are under development.
Research Projects Completed - Selected List
| 1047-RP - Development of a humidity control design guide |
 |
This project was completed in 2001. It produced the 512-page book titled "Humidity Control Design Guide for Commercial and Institutional Buildings", which is now available for sale at the ASHRAE electronic bookstore. A summary of the books content and its recommendations is described by a technical paper which was presented at ASHRAE Indoor Air Quality 2001 conference in San Francisco. Our technical committee was a co-sponsor of this project, and one of our members became the lead author for the book.

| 816-RP - Recalculation of weather design values for the ASHRAE Handbook of Fundamentals |
|
This project was completed in 1997. It produced correct design values for use in calculation of peak moisture loads which is now contained in chapter 27 of the Handbook of Fundamentals. Surprisingly, this data had never before been calculated in ASHRAE's 100-year history. The project was initiated by our technical committee because the collected experience of our members showed clearly that the previously common design practice of using peak sensible design values for calculating moisture load grossly underestimates the true peak moisture load.
