Project Case Studies
CBE is studying UFAD buildings in operation to help the building industry learn from the collective experiences of these projects.
This research provides information about UFAD building design, operation, and performance,
and illustrates how designers have addressed design issues.
We are developing three levels of information about completed UFAD buildings.
The three levels of study, in progressively increasing detail, include:
1. Project database Candidate study projects are identified and key
information is added to our database. Individuals associated with each
building are asked to fill out a web-based survey that covers key
building characteristics. This database may be used to identify trends and characteristics of UFAD projects.
In the future we expect to make the database available online to allow queries from interested parties using the CBE survey report generator.
See a draft of the UFAD project
list (PDF, revised October 2007).
We also have created an interactive map of the UFAD
buildings in North America that we have identified so far. We are
interested in getting additional data on these buildings,
so if you are familiar with a UFAD
building and would like to contribute information towards this research, please
provide your contact information on the
data submission form so that we may contact you for more details.
Project profiles are developed via site visits and interviews with
project designers, owners/developers, and facility managers. The
project profiles document and characterize underfloor system design issues
and solutions, describe the operation of the system, evaluate the overall
performance, and list noteworthy attributes discovered during the studies.
We have completed six project profiles that represent a variety of
underfloor systems. We have posted project
profiles on this website for the following buildings:
BC Hydro, Burnaby, BC
CSAA, Livermore, CA
FNBO Technology Center, Omaha, NE
SMUD Customer Service Center, Sacramento, CA
Teledesic, Bellevue, WA
Telus, Vancouver, BC
field studies are conducted on a few selected projects.
The field studies focus in more detail on design and operation, costs, and
evaluate performance from physical on-site measurements, implementation of
occupant satisfaction surveys, and analysis of energy usage. Results
from our Teledesic Broadband Center Field Study has been documented
in a Summary Report (PDF
In addition, we are currently conducting an extensive comparison field study of
two buildings in the Capitol Area East End Complex in Sacramento, CA. Details
