About

Learn about the RetroCommissioning process and how to implement this process on an existing building, with lessons learned from a commissioning professional and Professional Engineers.

This course will give a quick overview of commissioning and the benefits of commissioning for existing buildings, followed by how to implement RetroCommissioning by walking the participant through each step of the process. Benefits of and difficulties with implementing the commissioning process on existing projects are evaluated. Finally, a sample case study is given by professional engineers, who discuss lessons learned on the Retrocommissioning implementation process.

Objectives

  1. Explain the benefits of commissioning a building
  2. Evaluate existing building opportunities
  3. Demonstrate the RetroCommissioning Process
  4. Determine how to implement retrocommissioning for an existing building, by applying case study knowledge and lessons learned

Overall a good course. Could spend less time "selling" commissioning since this is a course for technical people, not owners. Examples of problems found in the field (diffusers cut to make room for pipe, air handling unit where maintenance door can not open fully) are examples copied from the building commissioning module and really have no place in retro-commissioning. Provide better examples of what you find when retro-commissioning (old equipment, poor maintenance procedures, mold). Still, of the four USGBC courses I have completed to date, this is the first one I would recommend to others.

Thank you for taking the time to provide your comments. Several of the presentation examples including the cut ceiling diffusers were identified during a Retro-commissioning project and some were ideal low-cost / no-cost measures or improvements that met the project criteria for implementation. Thank you again for taking the time to provide your comments.

This is a good course as it outlines the all the procedures that are necessary to go through retrocommissioning for existing building. It also signifies that why commissioning is important part that every institution shall go through.

The course is owner and building manager orientated. But it is still useful for other professionals.
More of the spoken points could be shown in the slides however.

I would appreciate more educational presentations for the experienced commissioning and energy engineering professionals. This presentation was not educational for me; I've seen the same basic concepts presented dozens of times in the past 15 years. Time to stop repeating Cx basics and start helping each other deliver results that are meaningful and affordable to our clients. The amount of paperwork that this presentation suggests is necessary is way too much!

Also, Cx Providers and Energy Engineers: Please stop using simple payback; it is a meaningless statistic - especially ridiculous when talking about ongoing commissioning. ALL future ownership costs must be considered when evaluating energy efficiency projects, not just predicted energy savings. The best way to assess energy projects in life cycle cost analysis.

Plus, the go/no-go determination in simple payback years in completely arbitrary. In the example given in this presentation, the utility demands that all measues that payback in 4 years be implemented. Why not 5 years? What's better: a 4-year payback with a 5-year life expectancy or a 10-year payback with a twenty-year life expectancy? What about ongoing maintenance cost comparisions between the two choices?

Senior Commissioning Consultant, Green Building Services, Inc.

We appreciate your comments. The project case study presented was a utility funded program and the RCx documentation, payback calculations and go/no-go thresholds were all program mandates/requirements. I would agree that Life Cycle Costs are a much better tool for determining energy conservation measure implementation. Thanks again for taking the time to view this presentation and providing comments.

Commissioning Engineer, Leidos

I understand that your work was defined by your client. My point is that, as commissioning and energy engineering professionals, we should be leading our clients toward meaningful projects and away from worthless simple payback analysis. Life-cycle cost analysis may be more difficult to do, but the results are just as easy to understand as simple payback, even for complete lay-persons. Most people who are in charge of defining and acquiring commissioning work and energy efficiency projects are lower-level administrators who have never heard of life-cycle cost analysis, so they don't ask for it. I suggest that it is time that our profession start educating our clients, rather than having them lead us into performing meaningless work.

Especially, I urge those within our profession to stop writing educational articles that treat simple-payback as if it was a legitimate metric.

An excellent, highly detailed, step by step process to undertake building commissioning and retro commissioning in buildings. Great (real) photographs and detailed graphs and slides. Good presenter keeps the flow going (even with a little repartition) but at least makes it real.

This course will be very helpful for project team members working on LEED for existing buildings as well as facility managers in charge of building operations as it highlights the importance of building systems commissioning. Additionally, it provides a step-by-step approach of how to implement commissioning process at existing buildings. Consistency in structure, way of presentation and outcomes is clear throughout the course. On a personal basis, this course allowed me to better understand commissioning process at existing buildings.

Well done presentation with detailed process AND excellent examples and images! They do an great job with the total Retro-Commissioning process and describe a good standard-of-care for this kind of a project. The example of a real project with lessons learned was a good addition to the overall presentation.

We appreciate your kind words.

Very useful overview of the commissioning process for me.
I am involved in a similar type project retrocommissioning activity now with a certified commissioning agent.
This course supported my learing in this area.

Thanks for the comment. I am happy that this course supported your learning of existing building commissioning.
