Whole-Building Recommissioning in North Vancouver
Older commercial buildings rarely fail all at once. They drift. Schedules stop matching occupancy, sensors fall out of calibration, exhaust fans quietly underperform, and the result shows up as hot-and-cold complaints on the same floor. Monolith Housing Solutions was retained to complete a whole-building recommissioning and operational optimization project at 2030 Marine Drive in North Vancouver, correcting those deficiencies through investigation and verified adjustment rather than premature equipment replacement. This project follows the same diagnostic discipline as our building commissioning service, applied to a building that has been in continuous operation for four decades. Below is how the scope was defined, what the field investigation covers, and what the owner and tenants gain from it.
Project Snapshot
- Location: 2030 Marine Drive, North Vancouver, British Columbia
- Building type: Four-storey multi-tenant office building
- Year constructed: 1984
- Floor area: Approximately 23,984 ft²
- Program context: BOMA Enspire Retrofit Ready Program
- Service: Existing building commissioning (EBCx), functional testing, ventilation and pressure diagnostics, operational optimization, operator training
- Performed by: Monolith Housing Solutions
- Goal: Identify and correct operational deficiencies, improve occupant comfort and indoor air quality, reduce avoidable energy use, and replace reactive maintenance with structured preventative procedures
The Building We Work In Every Day
2030 Marine Drive is not a case study observed from the outside. It is the building Monolith Housing Solutions occupies, which means this recommissioning methodology was applied first to the spaces the team works in daily. That changes the standard of proof. Temperature variation between floors is experienced rather than read in a summary, ventilation performance is judged over months instead of a single site visit, and every schedule change or setpoint adjustment is measured against how the building actually behaves the following week. The same methodology is applied to commercial buildings across the Lower Mainland. It was tested here first.
The Starting Point: A 1984 Building Running on Standalone Controls
The building is served by existing HVAC, hydronic, ventilation, plumbing, lighting, and electrical systems, but it operates primarily through standalone controls rather than a centralized building management system. That distinction shapes the entire project. In a building with a modern BAS, much of the investigation can be done through trend data and remote overrides. Here, there is no central log to interrogate. Every schedule, setpoint, and interlock has to be verified at the equipment itself, which makes disciplined field procedure the difference between a real diagnosis and a guess.
The Concerns That Defined the Scope
Interviews with building management and a preliminary review of operations surfaced a set of concerns that were clearly related to one another rather than isolated faults:
- Non-uniform temperatures, with conflicting hot and cold complaints across tenant spaces
- Operational issues affecting the central HVAC system
- Insufficient or ineffective outdoor-air delivery
- Odour transfer between tenant areas and between building floors
- Potential pressure imbalances between spaces
- Limited preventative maintenance procedures
- A predominantly reactive approach to equipment maintenance
- Potential control, calibration, zoning, and air-distribution deficiencies
Why Odour Transfer Was Treated as a Building Physics Problem
Reported odour transfer at Level 1 and between Levels 2 and 3 received particular attention, because odour movement is a symptom rather than a cause. Air only travels from one tenant space to another when a pressure difference pushes it and a pathway lets it through. That points to exhaust performance, pressure relationships between zones, leakage through vertical shafts, stack effect across a four-storey structure, or unbalanced airflow between floors. Treating it as an air-freshener problem would have left the underlying mechanism in place, so it was scoped as a measurable airflow and pressure investigation from the outset.
A Two-Phase Recommissioning Strategy
Monolith developed a two-phase approach so that no corrective measure is implemented before the condition behind it has been confirmed by measurement.
1
Phase 1: Planning and Investigation
This phase establishes what the building is actually doing, as opposed to what its documentation says it should be doing. It begins with a review of available drawings, operating information, service records, equipment schedules, and existing maintenance practices, supported by interviews with ownership and operations personnel about recurring complaints, operating challenges, and historical system behaviour. The field work then verifies those accounts directly at the equipment.
2
Phase 2: Implementation and Verification
Once deficiencies are confirmed, corrective measures are developed, prioritized, and supported through implementation. Every implemented measure is subject to post-implementation verification to confirm two separate things: that the equipment now responds as intended, and that the change actually resolves the original operational issue rather than moving it somewhere else in the building.
What the Field Investigation Covers
The investigation examines the building as an interconnected system, covering mechanical operation, controls, air movement, water, lighting, and electrical condition:
- Building systems inventory and condition assessment
- Review of operating schedules against actual occupancy
- Thermostat, aquastat, and accessible sensor calibration checks
- Functional testing of HVAC equipment and standalone controls
- Verification of equipment enable and disable functions
- Review of operating sequences, alarms, and setpoints
- Assessment of air distribution within tenant spaces
- Ventilation and exhaust operational checks
- Relative-pressure measurements at entrances, doors, tenant areas, and vertical connections
- Investigation of odour-transfer pathways
- Review of simultaneous heating and cooling
- Domestic hot-water and plumbing-system review
- Lighting schedule, switching, timeclock, and occupancy-control checks
- Electrical-panel inspection for maintenance concerns, hot spots, and abnormal conditions
Electrical-panel screening in particular pairs well with our infrared thermal imaging work, where abnormal thermal signatures can reveal loose connections and overloaded circuits before they become failures.
Testing an Occupied Building Without a Central BAS
Because the building does not rely on a centralized building automation system, functional testing is performed directly at the equipment and standalone control level. Each test method is adapted to the existing system configuration instead of assuming a control architecture the building does not have. Just as important, the building stays occupied and working throughout. Testing sequences are planned to minimize disruption to tenants during normal building operation, which means coordinating pressure and airflow tests around tenant activity rather than shutting the building down to make the measurement easier.
Systems Included in the Recommissioning Scope
The scope covers the principal systems affecting energy performance, occupant comfort, indoor environmental quality, and operating reliability.
System group | Included in scope |
|---|---|
Air handling | Air-handling and air-distribution systems; outdoor-air, supply, and exhaust fans |
Hydronic | Hydronic heating and cooling distribution; terminal heating and cooling equipment |
Controls | Thermostats, sensors, timeclocks, standalone controls, system schedules, and operating sequences |
Plumbing | Domestic hot- and cold-water systems; sump pumps and associated controls |
Lighting | Interior and exterior lighting systems; switches, schedules, and occupancy sensors |
Electrical | Electrical panels and associated maintenance conditions |
Operational Optimization Measures
Corrective measures are developed from verified findings, with the emphasis on low-cost and operational improvements that deliver measurable benefit without immediately requiring major capital replacement. The table below pairs each measure with the condition it addresses.
Optimization measure | Condition it addresses |
|---|---|
Aligning equipment schedules with tenant occupancy | Equipment running outside occupied hours |
Correcting control settings and operating sequences | Comfort complaints and unstable system behaviour |
Optimizing hydronic and supply-air temperatures | Excess energy use and overheating or overcooling |
Improving outdoor-air and exhaust operation | Insufficient or ineffective ventilation |
Correcting pressure relationships between zones | Odour transfer between tenants and floors |
Reducing simultaneous heating and cooling | Systems working against each other |
Identifying passing control valves | Unintended heating or cooling flow |
Applying seasonal equipment-disable strategies | Off-season equipment operation |
Eliminating unnecessary lighting operation | Lighting energy outside occupied periods |
Identifying electrical-panel maintenance needs | Reliability and safety risk |
Improving water-use practices | Avoidable domestic water and hot-water consumption |
Developing current facility requirements and updated O&M documentation | Operating knowledge held informally rather than recorded |
Establishing structured preventative-maintenance procedures | Reactive, breakdown-driven maintenance |
Project Deliverables
Documentation is produced so that the building can be operated correctly after the project team leaves, which is where many commissioning efforts lose their value.
- Recommissioning plan
- Building systems inventory
- Site investigation and observation reports

Staff Training and Knowledge Transfer
Optimized settings only hold if the people running the building understand why they were chosen. Monolith provides practical training to the building operations and property-management teams, covering the project findings, revised equipment schedules, optimized setpoints, seasonal operating strategies, routine verification procedures, and appropriate responses to recurring operational problems. The objective is greater consistency in day-to-day operation and less dependence on reactive troubleshooting.
What Recommissioning Changes in a Building Like This
For a multi-tenant office building of this age and configuration, where day-to-day comfort drives tenant retention, recommissioning delivers on several fronts at once:
- Fewer comfort complaints, as temperature variation between tenant spaces is traced to calibration, zoning, and air-distribution causes rather than managed one thermostat at a time.
- Better indoor air quality, through verified outdoor-air delivery and corrected pressure relationships that close the pathways behind odour transfer.
- Lower avoidable energy use, by aligning operation with actual occupancy and eliminating simultaneous heating and cooling, which supports ongoing energy and carbon reporting obligations.
- More reliable operation, with preventative-maintenance procedures replacing breakdown-driven service calls.
This project demonstrates Monolith’s ability to investigate complex performance problems in an occupied commercial building, where HVAC operation, ventilation, pressure relationships, tenant comfort, indoor air quality, controls, and maintenance practices have to be evaluated as one interconnected system.
