Risk management
•Performance Evaluation Plan• Define how performance is to be evaluated• Move operational risk from the owner to the total project team
• Align guaranteed outcomes to specific responsibilities
•“Operational” Modeling• Rethink how we model buildings• Shift from ideal state to reality focus• Intent for long term use and application

CASE STUDY: Design Considerations LESSONS LEARNED
Energy modeling
was revisited
multiple times to
ensure it fit
operational
conditions.
M&V adjustment
methodology was
challenging to
finalize post
contract.
Iterative process used for collaborative development of the Performance Evaluation Plan
Modeling limitations identified early in design:
• eQuest capacity limited• Specialty systems calculated outside of
model

• Start tracking performance of systems during construction
• OPRs may change, but how does it affect the guarantee? Working in an occupied building presented challenges

Getting the right
data at the right
time in a manner
that it can be
leveraged
efficiently is an
ongoing challenge
for any project.
Implemented technology solution encompassing:
• 90% of energy end-use metered• Over 4,000 data points collected every 15 min• Key performance indicators for whole building
and end-use performance monitored in real time

Performance measurement• Technology is an enabler – NOT a tool
• Means to improve timeliness and efficiency by which we measure performance
Database – System of Record
Action
Reporting –Work Flow
Analytics – Automation of Performance Valuation
Building Systems –Raw Data

and operators
understand how
small changes (e.g.
changing set
points) would
affect energy
performance and –
most importantly –
the guarantee.
