Why Coastal Weather Makes HVAC Efficiency Important

Vancouver sits in a temperate zone, but cooling is still necessary. With warmer summers and urban heat island effects, commercial buildings in urban centres like Vancouver, Richmond, and Surrey see meaningful heating and cooling loads from June to September. Meanwhile, the grey, mildly cold winters, rarely below -0 °C but still persistent, mean heating systems run for months at a stretch. This dual demand makes a year-round HVAC strategy essential. A system tuned only for winter wastes energy during shoulder seasons and underperforms on the hottest summer days.

As a team offering residential and commercial HVAC services in Richmond and Vancouver, we constantly see this mismatch in older commercial buildings, and it’s one of the most cost-effective problems to fix.

Optimizing Heating and Cooling Setpoints

One of the simplest, high-impact changes is setting your temperature setpoints correctly. During the hot season, the target should be 21°C when the building is occupied and 16°C when it’s empty. For cooling, set the temperature no lower than 24°C during occupied hours. Given Vancouver’s mild climate, turn off mechanical cooling when the building is unoccupied.

A critical detail that many building operators overlook is the deadband between heating and cooling setpoints. The gap should be at least 2–3°C. Without this separation, heating and cooling systems fight each other. In other words, one turns on just as the other shuts off, wasting energy without improving comfort. This overlap is surprisingly common in Vancouver office buildings and is entirely avoidable with proper calibration.

In summer, the cool evenings are a genuine blessing. Running your HVAC system in economy mode overnight, drawing in cooler outdoor air to flush heat accumulated during the day, can significantly reduce the mechanical cooling load the next morning. This is a strategy we strongly recommend to commercial clients looking for assistance with heating and cooling throughout Greater Vancouver.

Smart Controls and Building Automation Systems

For most businesses, upgrading to programmable or smart thermostats is an easy win. These devices automatically step temperatures down at night and on weekends. This eliminates the costly habit of heating or cooling an empty office to full comfort levels. They are highly reliable, straightforward to install, and pay for themselves quickly given BC Hydro’s stepped pricing rates.

For larger or more complex commercial facilities, such as multi-tenant office buildings or retail centres, a full Building Automation System (BAS) offers more capability. A properly configured BAS manages heating, cooling, ventilation, lighting, and even domestic hot water as a coordinated whole. It can respond dynamically to occupancy, weather, and demand charges on your electricity bill. Energy savings typically range from 5% to 30%, with most systems paying for themselves in 2 to 4 years.

Harbour Energy Tip: Lock thermostat controls or restrict employee access. In our experience providing commercial HVAC service in Vancouver, unauthorized thermostat adjustments are a leading cause of unexpected spikes in heating and cooling costs.

Water heating controls are another underutilized tool. Outdoor reset controls, which vary supply water temperature in response to outdoor conditions, can meaningfully improve comfort and reduce operating costs. Shutting down hot-water circulation pumps during unoccupied hours with a time switch is a simple measure that can save thousands of dollars annually.

Reducing Heat Loss in Commercial Buildings

Local rain and humidity make building envelope performance more important than many property managers realize. Heat escapes not just through walls and windows but through uninsulated pipes, poorly sealed ducts, and gaps around loading doors. In a wet climate, those same pathways can introduce moisture that degrades insulation over time.

In high-ceiling spaces like warehouses, distribution centres, and manufacturing facilities, which are common in industrial zones such as East Van, Annacis Island, and the Fraser Valley fringe, warm air naturally stratifies near the ceiling. As a result, the heater runs almost constantly while occupants remain chilly at floor level. Installing ceiling fans to de-stratify the air is a low-cost, high-impact solution that can meaningfully cut heating energy in such environments.

In loading dock areas, especially, heat loss through open doors can be enormous. A relay that cuts heating when dock doors open, combined with vestibule partitions, can yield dramatic savings in buildings that receive frequent deliveries.

Insulate any pipes or ductwork running through unconditioned spaces, attics, parkades, and mechanical rooms. Uninsulated supply ducts in a cool parkade lose a significant fraction of their conditioned air before it reaches the intended space, especially during the long heating season.

Shutting Down Equipment When It’s Not Needed

One of the most overlooked sources of HVAC energy waste is equipment running when it doesn’t need to. Pumps, fans, and electric water heaters all draw power. In commercial buildings, they often default to “always on” unless someone actively programs otherwise. Establishing a discipline around equipment shutdowns, tied to occupancy schedules and outdoor temperature thresholds, can deliver consistent savings with no capital investment.

Heating circulation pumps, for instance, can often be shut down entirely when outdoor temperatures rise above 18°C — which happens regularly from late spring through early fall. Similarly, shut down chiller systems, condenser water pumps, and cooling tower fans as early as possible in the evenings and on weekends, except where dedicated computer room cooling is required.

Only Cool Necessary Spaces

Many commercial buildings heat and cool every square metre uniformly, regardless of whether those spaces are occupied. Vestibules, stairwells, storage rooms, and underused lobbies are common culprits. Redirecting or reducing HVAC delivery to these low-occupancy zones, or shutting them off, can trim energy costs without affecting anyone’s comfort.

In open-plan offices and retail environments, internal heat gains from lighting and office equipment are substantial. Every watt of power consumed by lighting, computers, or kitchen equipment eventually becomes heat in the building, adding to the cooling load. Switching to LED lighting, enabling power management on office equipment, and using a timer to shut down kitchen exhaust fans during unoccupied periods all reduce the burden on your cooling system during Vancouver’s summer months.

HVAC Maintenance: The Foundation of Efficiency

The damp, coastal climate takes a toll on HVAC components. Cooling tower fouling, condenser coil debris, and clogged filters all reduce system efficiency and drive up energy consumption, often invisibly, until equipment fails. Proactive HVAC service in Richmond isn’t optional; it is the baseline against which all other efficiency gains are measured.

Keep condenser coils clear of debris, especially in spring when biological growth is active. Cooling tower basins, intake strainers, and spray nozzles need regular inspection and cleaning to maintain both air and water pressure performance. Replace or clean filters on a schedule calibrated to your actual operating environment—urban areas have meaningful particulate loads that can shorten filter life relative to the manufacturer’s estimates.

Beyond cleaning, annual calibration of thermostats, sensors, dampers, and controllers ensures that the controls actually match the setpoints you intend. A thermostat that reads 2°C high means your building has been overheated every winter day since it drifted out of calibration, a common and easy correction that stops unnecessary costs.

Heating and Cooling in Richmond & Vancouver: System Upgrades Worth Considering

For organizations ready to invest in long-term energy improvements, installing variable-frequency drives (VFDs) on fans, chiller water pumps, and heating pumps can yield substantial energy savings. HVAC motors often run at full speed regardless of load, using far more power than necessary. VFDs let motor speed match actual conditions, and because fan and pump power scales with the cube of speed, even modest speed reductions yield significant energy savings.

Buildings with constant air volume (CAV) systems are strong candidates for conversion to variable air volume (VAV) systems. Similarly, dual-duct systems, which mix separate hot and cold air streams at each zone, are inherently inefficient and can often be converted to single-duct systems with meaningful ongoing savings. These are larger capital investments, but they typically qualify for BC Hydro incentives and can be evaluated through an energy audit.
