Maine Medical Center RCx, Retrofit Planning, and Controls Upgrade

Cx Associates was retained by Maine Medical Center to provide an engineering assessment for optimizing the replacement of AHU-44, which is at the end of its expected service life. We recommended an advantageous solution and provided a design narrative for use in pricing. We provided services throughout the replacement, by evaluating hospital spaces and programs, space conditioning and ventilation requirements, performing submittal reviews, and developing the final sequence of operation. To round out the project, we will conduct site work to review the installation and operation.

Southwestern Vermont Medical Center

Cx Associates conducted a retrocommissioning qualification study for the chilled water plant at the Southwestern Vermont Medical Center. Our review of the facility focused on its chilled water plant, the BAS, as well as pumps and the cooling tower. Our study resulted in four measures we recommended to the owner. These four measures resulted in estimated annual savings of $17,000, which would result in a payback period of just 1.4 years.

Northwestern Medical Center Air Handling Unit Retrocommissioning

Cx Associates worked with Efficiency Vermont to complete a retrocommissioning (RCx) process of nine Air Handling Units (AHU) at Northwestern Medical Center (NMC). The nine AHUs analyzed in this RCx study served several areas of the 200,000 square foot medical building including operating rooms, surgical services, ICU, PCU, laboratories, cafeteria, office spaces, and the emergency department. In addition to the original scope, we identified three further items during the implementation phase of the work that would give additional savings of over $9,000 per year. The final RCx report indicates savings of over $33,700 per year.

Fanny Allen Hospital Comprehensive Building Automation System (BAS) Upgrade

We provided design and sequences of operation for an upgrade to Fanny Allen Hospital’s aging Building Automation System (BAS). This upgrade resulted in an increase in the facility’s Energy Star score from 15 to 31. Our team based our design on the not-yet-released ASHRAE Guideline 36 and implemented leading edge efficiency measures in the control of the HVAC systems.

Northwestern Medical Center Master Facilities and Chiller Plant Upgrades

Cx Associates provided commissioning services for Construction and Post-Occupancy phases of this multi-building project. The overall project was comprised of three separate projects: the ICU/Medical-Surgical addition, which included twenty new single occupancy patient rooms; the main entrance and lobby renovation, which included the outpatient clinic addition and contained multiple exam rooms; and a new standalone medical office building.

Maine Medical Partners Medical Office Building

Cx Associates provided design, construction, and occupancy phase commissioning services for this Compounding Pharmacy and Medical Office Building which houses dedicated dermatology and chemo infusion clinics along with a pharmaceutical lab. Because we were involved since the design review, we were able to work with the owners, designers, and contractors to ensure the compounding pharmacy HVAC system will satisfy the strict code requirements for this type of space.

Maine Medical Center Bramhall Campus

Cx Associates is commissioning this four-phase construction project, including the Congress Street Clinical Building, East Tower Vertical Expansion, Existing Visitor Garage Vertical Expansion, and Central Utility Plant Chiller. We are providing design, construction, and occupancy phase commissioning services for this project as well as occupancy phase monitoring-based commissioning. In addition, we worked with Maine Medical Center to develop an in-depth facilities Owner’s Project Requirements document that they are now using to inform other projects.

University of Vermont Medical Center Miller Inpatient Building

Cx Associates led the development of the Owner’s Project Requirements (OPR), and then provided commissioning services for Design, Construction, and Post-Occupancy phases of the project. Our design reviews resulted in over $220,000 in first cost savings and we identified and suggested solutions for over 200 issues during construction.

Currently we are providing measurement and verification services in compliance with LEED 2009-NC Version 3.0 – EAC 5 for Measurement and Verification. This work includes commissioning metering devices, building a public-facing web page that charts the Energy Use Intensity of the building, writing and executing a measurement and verification plan, and developing an energy model to measure actual building energy performance in comparison to baseline.
