When examining energy use and thermal comfort, the subset of buildings that had under
floor air distribution (UFAD) systems appeared to have better energy performance and
lower thermal comfort scores. However, the buildings with UFAD systems have them only
in part of the building. In contrast to the whole building data shown in Figure 14, the
Center for the Built Environment survey results were examined by location within one
building, and the space in the building that had the UFAD system had the highest thermal
comfort scores in the building, with the other spaces scoring low, resulting in a low number
for the whole building. Although it is interesting that this subset of buildings has better
overall energy performance and lower thermal comfort scores, this is a very small sample
and even a meta-analysis within this building set showed there is evidence that the whole
building satisfaction levels are not representative of all UFAD spaces.UderfloorAir ye

Figure 14. Energy Star score and thermal comfort with UFAD
Although there is value in high-level, whole building performance analysis, Figure 14 is an
example of how summary data can be misleading if not carefully examined. The whole
building performance data provided in this study is intended only for a summary analysis of
the portfolio and to identify areas where further investigation may be needed.37
