With energy prices rising across Canada and winter temperatures dropping sharply, heating costs have become one of the biggest seasonal challenges for property managers. Residential and commercial buildings consume significantly more energy during winter — often 30% to 50% more — due to increased heating loads, reduced daylight, and greater strain on HVAC systems.

For condos, multi-unit residential buildings, commercial towers, and mixed-use properties, cutting winter heating costs isn’t just about saving money. It’s also about:

• Improving energy efficiency
  
  
• Reducing mechanical failures
  
  
• Extending equipment lifespan
  
  
• Enhancing tenant comfort
  
  
• Lowering carbon footprint
  
  

This guide outlines practical, verifiable strategies that property managers can apply immediately to reduce winter energy consumption — while keeping buildings safe, warm, and compliant with Canadian standards.

Why Winter Energy Optimization Matters

Canadian properties face several winter-specific challenges:

• Higher HVAC demand due to prolonged sub-zero temperatures
  
  
• Heat loss from poorly insulated walls, windows, and roofing
  
  
• Increased risk of HVAC inefficiencies or breakdowns
  
  
• Frozen pipes causing energy waste
  
  
• 24/7 use of heating systems in multi-unit properties
  
  

Heating costs can account for up to 60% of total winter utility expenses in multi-residential buildings.

Optimizing building systems not only cuts costs — it prevents emergencies, reduces carbon emissions, and makes the building more resilient.

Optimize HVAC Systems for Maximum Efficiency

HVAC systems work significantly harder in winter. A few targeted improvements can drastically reduce wasted energy.

‍

1. Schedule Preventive HVAC Inspections

Preventive HVAC maintenance should always be performed before cold weather peaks. Key tasks include:

• Cleaning coils
  
  
• Inspecting heat exchangers
  
  
• Checking flue and vent systems
  
  
• Testing system pressure
  
  
• Lubricating moving parts
  
  
• Replacing filters (monthly or quarterly)
  
  

Dirty filters alone can increase HVAC energy use by up to 15%.

Tip: Track recurring maintenance tasks digitally using Onsite HQ to avoid missed inspections.

‍

2. Balance and Calibrate the System

Many energy losses come from imbalanced heating and airflow.

Property managers should ensure:

• Thermostats are calibrated
  
  
• Dampers and vents distribute heat evenly
  
  
• Airflow is unobstructed
  
  
• Exhaust fans aren’t over-running
  
  

Imbalanced HVAC systems cause some units to overheat while others stay cold — leading to unnecessary tenant complaints and higher bills.

‍

3. Upgrade to Smart Thermostats and Controls

Smart building controls optimize heating based on real-time data. Benefits include:

• Temperature setbacks during off-peak hours
  
  
• Occupancy-based heating
  
  
• Better indoor air quality control
  
  
• Automated scheduling
  
  
• Reduced overheating in common areas
  
  

Buildings with smart controls can reduce heating consumption by up to 12%.

‍

Improve Building Insulation and Reduce Heat Loss

Heat loss is one of the biggest contributors to winter energy waste — especially in older buildings.

‍

1. Inspect and Seal Windows & Doors

Air leaks can account for 25–40% of winter heat loss.

Property managers should:

• Replace worn weatherstripping
  
  
• Seal cracks around frames
  
  
• Install insulated curtains in common areas
  
  
• Repair drafts reported by residents
  
  

‍

2. Add or Improve Insulation

Consider insulation upgrades in:

• Attics and roof cavities
  
  
• Exterior walls
  
  
• Mechanical rooms
  
  
• Pipes exposed to outdoor-facing walls
  
  
• Basement ceilings
  
  

Even small insulation improvements can cut heating costs by 10–20%.

‍

3. Reduce Heat Loss in Common Areas

Areas often overlooked include:

• Laundry rooms
  
  
• Storage rooms
  
  
• Parkade entrances
  
  
• Utility corridors
  
  

Ensuring these spaces stay properly sealed helps maintain overall building efficiency.

‍

Preventive Furnace and Boiler Maintenance

Furnaces and boilers are the backbone of heating in many Canadian residential buildings.

Key maintenance tasks include:

• Annual professional inspection
  
  
• Thermostat calibration
  
  
• Flame sensor cleaning
  
  
• Boiler scaling checks
  
  
• Pump and valve testing
  
  
• Ensuring proper combustion air supply
  
  

Well-maintained systems last longer and consume significantly less energy.

Pro tip: Log each inspection inside Onsite HQ to build a year-over-year performance history.

‍

Use Smart Temperature Strategies

Small temperature adjustments can generate large savings without compromising comfort.

‍

Optimal settings for multi-unit buildings:

• Occupied spaces: 21°C
  
  
• Hallways/common areas: 18–19°C
  
  
• Utility rooms: above 10°C to prevent freezing
  
  

Other helpful strategies:

• Lower temperatures slightly at night
  
  
• Avoid overheating lobbies
  
  
• Ensure thermostats aren’t blocked by furniture or décor
  
  
• Use zoning to heat only where needed
