Retro-Commissioning, Re-Commissioning, and Testing, Adjusting, & Balancing (TAB) of $10M multi-phase 1.1M square foot project, encompassing 31 buildings across Naval Station Everett, Smokey Point Naval Support Complex, & Jim Creek Naval Radio Station, WA, including:
- Administrative Office Buildings,
- Operations Office Buildings,
- Daycare Center,
- Galleys,
- Fire Station,
- Auto Shop/Repair,
- Exchanges,
- Commissary,
- Fitness & Natatorium,
- Bachelor Enlisted Quarters,

Testing, Adjusting, & Balancing (TAB) services per Washington state energy code (WSEC), NEBB TAB standards, and Naval Facilities Engineering Command (NAVFAC) requirements, including design review, submittal reviews, coordination meetings, TAB surveys, TAB agenda submittals, incorporation of TAB activities into project schedule, observation of deficiencies, commissioning coordination and back check, and submission of TAB final reports per building. Balanced air distribution systems included: constant volume air handling units, variable volume air handling units, industrial makeup air units, packaged rooftop units, heat recovery makeup air units, dedicated outside air units, fan coil units, heat pumps, fan-powered series terminal boxes, fan-powered parallel terminal boxes, squeeze boxes, fume hood exhaust, kitchen hood exhaust, and paint booth exhaust. Balanced hydronic distribution systems included: chilled water and heating hot water (constant volume and variable volume). NEI TAB team coordinated with building maintenance staff and contractors to fast track repairs, sheave changes, belt changes, motor replacements, speed controller installations, and system adjustments on existing and renovated systems to maintain project schedule, while providing comfortable work environments for building occupants, prolonging equipment life cycles, and improving system efficiencies.
Whole Building Commissioning (Cx) services were provided per Washington state energy code (WSEC), NEBB Retro-Cx & Re-Cx standards, and NAVFAC requirements, including design review, sequences of operations review, submittal reviews, coordination meetings, site visits, incorporation of commissioning activities into project schedule, witness of major equipment startup, writing and execution of pre-functional checklists and functional performance test reports, back check of testing and balancing (TAB), tracking of observed deficiencies into deficiencies log until closure, witness of Owner training, review of O&M manuals for commissioned systems and incorporation into project systems manual, and diagnostics testing / review of trend reports after substantial completion within each building. Commissioned systems included heating, ventilation, air conditioning, & refrigeration (HVAC&R), and Building Automation System (BAS).
Project-specific Retro-Cx and Re-Cx included investigating, reviewing, and analyzing existing building issues discovered during early site investigation phase, prior to contractor renovations. NEI worked directly with building managers, maintenance facilities groups, and end users to compile building surveys and Conceptual Energy Analyses per building, each with building/system-specific recommended design modifications. Recommended corrective actions were reviewed by the entire Cx Team from a global point of view, comprising of short-term improvements and/or long-term system reconfigurations/adjustments to the building’s air distribution, equipment components, and building automation sequences, as applicable. Recommended energy conservation measures were supported with life-cycle cost analyses. Retro-Cx, Re-Cx, and TAB services optimized the systems performance, energy efficiency, occupant comfort, & indoor air quality.
