Monitoring Based Commissioning (MBCx)
Monitoring Based Commissioning (MBCx) will be a pilot program
for the CCC/IOU Partnership for the 2006-2008 Energy Efficiency
Program cycle. The program will borrow heavily from the UC/CSU
Partnership, which successfully demonstrated the value of this
approach, and will adapt many of the same guidelines and procedures.
It is envisioned that once pilot projects are completed at various
campuses, the program will be disseminated statewide and will
eventually become a significant component of the CCC/IOU
Partnership's energy savings portfolio.
This element of the program is a unique approach to obtaining
savings that combines the expertise of the Universities' statewide
campus facility management staff, additional utility and
subcontractor expertise, and the installation of energy monitoring
and metering equipment at the building submeter and system level.
Through these resources, a systematic, comprehensive continuous
commissioning program will be developed. To date, almost every
retro-commissioning program has consisted of a one-time review of
building operations, installation of equipment control measures, one
or two training workshops, and possibly development of commissioning
documents.
The approach of this portion of the partnership program is far
different. It includes the usual first step, a review of building
operations and installation of equipment. However, it will go beyond
the typical program to date in three aspects. First, the campuses
that participate in this aspect of the program will install
sufficient equipment to insure an extensive and comprehensive
built-in measurement and verification capability. Second, this
element of the program will be combined with the third element
(Energy Efficiency Education and Best Practices Development and
Training) to become a "continuous commissioning" program, that is
institutionalized at the campuses for the foreseeable future. In
this way, savings will be sustained well beyond those from the more
typical and limited retro-commissioning programs. Third, the program
will use the campus facilities management staff to identify new
cost-effective retrofit opportunities efficiently and at low cost.
The key to success for this effort will be the existing
infrastructure that the CCCs bring to this program - extensive
campus facility management staff who are already well-versed in
energy skills but who lack the tools to implement continuous
commissioning and the specialized training needed to do so in-house.
Building commissioning is increasingly recognized as a
beneficial, cost-effective process to ensure optimal building
performance, reduce energy use, and improve indoor air quality,
occupant comfort and productivity. Over the past ten years,
utilities in California and across the United States have been
important supporters of the commissioning industry, and their
support has led to significant energy savings. Still though, most
buildings have never undergone any type of commissioning or quality
assurance process, and are therefore likely performing well below
their potential. Further, almost all of the commissioning work done
to-date has been with new construction. Where these has been
retro-commissioning (commissioning of existing buildings), it
typically has been a "one-time" approach, as opposed to an
integrated retro- and continuous commissioning program. There
are very substantial energy saving opportunities in existing
community college buildings. The unique approach of this program -
continuous commissioning using existing campus facility management
staff and development of "best practices" methodologies that are
used on an on-going basis - will ensure persistency in savings not
seen by the typical retro-commissioning program to date.
Three Components
As noted above, this element of the program is a unique approach
to obtaining savings that combines the expertise of the community
colleges' statewide campus facilities management staff, additional
utility and subcontractor expertise, and the installation of energy
monitoring and metering equipment at the building sub meter level.
It will be integrated with the existing expertise of campus
facilities management staff and the third element of this
partnership program (Energy Efficiency Education and Best Practices
Development and Training) so that it delivers persistent savings not
experienced in typical retro-commissioning programs and
simultaneously identifies additional cost-effective retrofit
opportunities efficiently and at low cost.
This program element is comprised of three components, Energy
Information Systems/Building Diagnostics, Facility
Retro-Commissioning, and Continuous Commissioning. This third
element, Continuous Commissioning, done by campus staff using the
expertise gained in the Education and Training element of the
partnership program and their experience with the
Retro-commissioning component in this program element, is a unique
undertaking that will ensure continued savings not typically
achieved in building commissioning efforts. The UC/CSU/IOU team will
implement each component as follows:
Energy Information Systems/Building
Diagnostics
Central monitoring and data acquisition systems will be procured
and installed to give campus facilities management staff the tools
to reduce energy consumption and peak demand at the campuses by
having consolidated energy information at the building system level.
This aspect will incorporate a facility needs assessment where
hardware needs will be investigated, such as sub-metering each
building and locating monitoring points on major energy usage areas.
Software needs, such as databases to display and archive system and
building performance, will also be considered. Monitoring systems
will be permanently installed by subcontractors hired under this
program or campus facilities management staff and used by campus
facility management staff to perform facility retro- and continuous
commissioning as described below.
Facility Retro-Commissioning
Based on the energy information systems and building diagnostic
tools described above, existing campus facilities management staff,
using the additional utility and subcontractor expertise supplied
under this program, will retro-commission select buildings and
central plants to get them operating as efficiently as possible.
Prior to this work, campus facilities management staff will have
received training in Best Practices Retro-commissioning under the
Education and Training element of this partnership program. Campus
facilities staff will use the knowledge from the classroom training
sessions and will work directly with experienced commissioning
agents during actual commissioning to gain hands-on experience.
Continuous Commissioning
In order to ensure sustainable, ongoing energy savings, the
college staff, again with the help of the utilities and expert
subcontractors, will establish a program to continuously commission
the buildings, using monitoring systems to ensure ongoing efficient
operations. As with the Retro-Commissioning activity, this aspect of
the program will be depend upon the Best Practices training received
under the third element of this partnership proposal (Training and
Education). Campus facilities management staff will attend
Commissioning Best Practices classroom training sessions annually to
ensure their commissioning skills remain current and new campus
facilities management staff receive adequate training. Ultimately,
the CCCs will have both the trained staff, and the permanent
monitoring systems to continue to commission the buildings over
time, thereby ensuring persistent energy savings. The facilities on
CCC campuses are often similar to one another; and the experience
gained from performing a retro-/continuous commissioning project on
one facility can be reproduced on another facility on a different
campus.
Both the retro-commissioning and continuous commissioning effort
will also be developed and implemented so as to identify
cost-effective future energy retrofit projects. The combination of
retro-commissioning and continuous commissioning will extend the
useful life (and energy savings) of the commissioning measures
beyond the persistence assumed to date from existing
retro-commissioning programs. The CCC/IOU team will coordinate with
other organizations and institutions performing building retro
commissioning studies and programs.
