Trends in design and operations of UFAD buildings
In this draft report we provide preliminary details of results from our web-based questionnaire survey tool used to collect design and operational information on existing UFAD buildings. This project makes up part of CBE’s overall UFAD Case Studies project dedicated to learning about how UFAD buildings perform in actual practice. Fifty buildings were selected from our database of about 300 UFAD projects in North America. Invitations were sent to project team members to complete the web-bases survey; responses were received from 39 projects over a period beginning in November 2003 to August 2005. Although the sample size is too small to gauge how representative these results are, it does indicate that for the most part UFAD buildings are operating reasonably well. The results also suggest a “typical” UFAD building which is outlined in the Summary and Conclusions section.
