Retrocommissioning

Only a small percentage of the existing building stock was ever commissioned, and as a result few buildings function as the design intended. RetroCommissioning is a methodical assessment process that identifies deficiencies in operation, design, and maintenance and develops solutions that are primarily focused on reducing operating costs. Every building is different - solutions may be as straightforward as reducing energy waste, and as holistic as improving occupant productivity through improved indoor environmental quality.

Utility Cost Reduction

Most buildings today are operating inefficiently. Facility personnel need to focus on maintaining occupant satisfaction and equipment functionality. Ensuring optimal energy efficiency is not integrated into existing standard O&M practices. Research shows that opportunities to reduce energy consumption exist in your building right now. Retrocommissioning is a highly effective energy conservation tool - in some cases delivering 25% reductions in energy consumption with simple paybacks as low as 8 months! The source of these energy savings can be traced to conditions that are common in all types of facilities:

• Long term "tweeking" of control devices to satisfy occupant demands.
• Equipment operating schedules determined by worst-case scenarios that are not in line with current occupancy schedules.
• Non-optimal or uncommissioned control setpoints and sequences.
• Uncalibrated control system components.
• Simultaneous heating and cooling.
• Constant volume equipment serving variable-demand loads.
• Dirty or clogged filters and coils.
• Faulty, inoperable or missing system components and equipment.
• Lack of operator training at original building system startup.
• Inappropriate maintenance focus.

Retrocommissioning is designed to uncover these common building operation deficiencies and improve the energy and comfort performance of your facility.

Retrocommissioning is a powerful energy conservation and comfort improvement tool but its ongoing value only comes from sustained application. Building systems often return to an "out of tune" state without appropriate maintenance. This normally leads to a resumption of occupant comfort complaints, rising energy costs and ever increasing demands on your maintenance staff to respond - a vicious cycle that simply increases the probability of building system problems. Improving the operation of your building starts with a well trained staff that understands the importance of maintaining the improvements you gained from your Retrocommissioning project. Numerous studies have proven that "commissioning based" maintenance of critical building systems saves time, reduces comfort complaints, trims energy costs and frees up in-house staff to focus on your day-to-day business and long-term building asset value.

Offered exclusively by RetroCom Energy Strategies, Supported Retrocommissioningsm enables our clients to carry on the work we have performed in their buildings, after our project with them is complete. This unique program offers critical skills training, maintenance management support, and measurement & verification of system performance that deliver the sustained outcomes you should expect from a Retrocommissioning project. Ultimately, we enable your staff to become your on-site Retrocommissioning experts through practical skills enhancement and ongoing project monitoring.

If you are like most clients, you want to be certain that your investment in a building system improvement program actually delivers results. And like most companies, RetroCom Energy Strategies wants to deliver those results. That's why our approach offers support beyond the completion of your project. Our post-project plan includes a full year of energy conservation measurement and building operator skills support:

• Ongoing Systems Monitoring
• Energy Engineering Support
• Maintenance Support
• Quarterly Energy Reports
• Quarterly Maintenance Reports

We believe strongly that the nature of training and maintenance in existing facilities has a direct impact on equipment performance, comfort conditions, energy consumption and employee commitment. We further believe, and independent studies have confirmed, that ignoring these factors contributes to deterioration of the gains captured during Retrocommissioning and eventually, a return to the very conditions that existed prior to commencement of the project.

Our objective is simple - to ensure that your investment continues to deliver value well beyond the completion of your initial Retrocommissioning project. Supported Retrocommissioning accomplishes that objective!
