Two different strategies with great benefits

Building commissioning and re-commissioning are becoming a standard strategy for many building managers and owners. It started to grow in popularity over the last five years to answer the large demand of energy efficiency projects. Although this kind of solution brings substantial improvements to the building systems, savings may not be maintained over time if management processes are not reinforced as well. This is why ongoing commissioning, or continuous commissioning, is growing in importance in the market.
commissioning can be applied in two very different formats. It can
either be fully implemented within the building management processes to
allow the user to be independent, or it can be delivered as a service
by a subcontractor. This article explains both solutions' benefits and
Implemented ongoing commissioning
Implementing ongoing commissioning often involves changing the actual management culture of the local building operation team. It means the facility managers and maintenance employees adopt a continuous improvement approach in every daily activity to seriously improve energy savings and better manage operating costs. They use new implemented technology, on-site, to monitor their building and guide their decision making process.
Three main challenges reside in being fully independent with ongoing commissioning. The first one is obviously technology implementation within the team actual toolbox. Companies selling the approach provide all the required technical support, installation services and coaching to successfully start the process. However, local management needs to establish the proper training program to make sure all the employees understand the tools they are going to use. It requires a good analysis of the team knowledge and a plan on how to close the gaps.
The second challenge is to promote the continuous improvement culture and accelerate its adoption. Training the staff on a new technology is something simple enough to quickly generate benefits, but changing a management culture needs more time and discipline. When using ongoing commissioning, the team needs to change their thinking and open their management vision to new opportunities. It’s with coaching and success sharing that each person will understand the value added of ongoing commissioning.
The last challenge
is the end result of the two previous ones. In fact, training people
and implementing procedures in a team overloaded with tasks is the true
challenge. It is already hard to complete all the required work in
maintenance and emergencies that it is often too hard to implement new
methodologies and technology. This is why being independent in ongoing
commissioning requires a good training, a strong team in place and
clear targets to aim for.
ongoing commissioning can generate enormous benefits. A team that uses
ongoing commissioning as their own internal management strategies is
definitely in front of the competition. With this continuous
improvement culture, every team member acts as an analyst of the
building systems and generates value added information for decision
making. All this involvement simplifies improvement opportunities
identification and accelerates corrective actions implementation
because every member follows the same strategy and works to meet the
Another benefit of implementing ongoing commissioning on-site is to standardize the analysis at every management level. Using this approach reduces wasted time searching, analyzing and understanding the root cause of a problem. It also builds the team knowledge about the building systems, which enables to increase team productivity and reinforces building operations. Moreover, all team members speak the same language, which simplifies communication, one of the biggest challenges in any administration.
With today’s technology, multiple services are available offsite and a big part of ongoing commissioning can be done this way. Some companies in the industry are offering ongoing commissioning as a service, meaning that an external engineering team is looking at building systems with offsite connections. Often called remote commissioning, this method generally involves a sub-contractor (or a monitoring center in large portfolios) who analyses the building operations 24/7 and generates reports for the building managers. Most of the time, these reports include data about control systems and energy consumption with related corrective actions to improve overall building performances.
commissioning involves similar challenges as any other service supplied
to the building management team. Security in data exchange is a good
example. Many enterprises don’t want to share business related
information to limit risks of improper usage. Obviously, remote
commissioning deals with external connections to the building, but with
the right system in place, all the information sharing is fully
secured. Using remote services also means more coordination and more
communication with an external supplier. This increases the difficulty
in communicating the problem details or a solution to a local team, but
a big variety of tools like webcast, real time image exchange or cloud
database are available to simplify information sharing within various
Another challenge of remote commissioning is to use outsourced analysis in day to day operations. It is not always easy to quickly understand an analysis and start the action suggested by someone not necessarily aware of on-site emergencies and priorities. To minimize difficulties, the team can simply put in place prescheduled periods to revise priorities frequently based on reports items each time the data arrives.
Even if remote
commissioning may seem riskier, it has many advantages to consider. Not
having to implement and take ownership of new technologies means
significant savings in time and training. In a service format, the
overall cost of implementing ongoing commissioning can be spread on a
longer term reducing initial investments. This allows starting several
projects at the same time, which is a very useful when the team manages
a portfolio of buildings.
If the building
management team adopts the proper procedures to use the supplied data
from each report, overall energy savings and productivity increase can
be impressive. Working with a professional of remote commissioning on a
frequent basis helps the team learn faster and access a standard level
of analysis from the very beginning of the project. Basically, remote
commissioning brings a new team player with a strong expertise to the
Which is best?
both solutions are good. It all depends on the business strategy the
building management team wants to undertake. On one hand, implementing
ongoing commissioning is a longer term solution that ensures a new
level of performance within the team. It starts a continuous
improvement culture to create a new management philosophy based on
waste elimination and opportunities identification that will keep going
over time. It generally answers owners’ objectives to reduce costs and
increase the overall building value in a mid to long term investment.
On the other hand,
remote commissioning allows an easy access to ongoing commissioning
benefits with fewer challenges on training. It enables the team to
exchange with experts and get good prioritized recommendations on what
to do to increase building performance. Remote commissioning usually
fits best short to mid-term projects in which quick savings are
targeted. Facility managers and building owners then need to first
identify their goal to then decide on how they will use ongoing
commissioning as their new management methodology.
