SECTION 2:
he findings in this paper are based on data
that originates from four main sources:
CAMPAIGN PARTICIPANT DATA: Quantitative
data were collected on floor area with EMIS, annual
energy use, and EMIS costs. Campaign participants
self-reported qualitative information such as the type
of EMIS installed, how the EMIS has been used, and
the most frequently implemented improvements in
which they utilized the EMIS.

PRIOR EIS STUDY: Energy savings and EIS
costs from a prior study of nine portfolio owners
(Granderson and Lin 2016) was combined with
Campaign participant data. This integration of
datasets was possible because the cost and savings
methodologies were the same, with the exception
that the prior study did not collect estimates of the
time in-house staff spent using the EMIS. The cost
and energy savings results were similar as well. By
combining these data sources, more conclusive
findings can be drawn because the dataset is larger.
Throughout the Campaign results, the data from
this study have been referred to as “2013 EIS study
participants” since the study was completed in
2013, although the final journal paper was published
in 2016.

CAMPAIGN PARTICIPANT AND INDUSTRY
PARTNERS SURVEY: An online survey was used
to obtain additional information about enablers,
barriers, and future technical needs associated
with EMIS.

ONGOING INTERVIEWS: Participants are
interviewed to better understand their current
EMIS and MBCx implementation, then participate
in activities such as individual and group technical
