Whole-Home Performance
Electrification & Mechanical Systems
Efficient systems. Lower loads. Better homes.
High-performance homes aren’t just about insulation and airtightness. Heating, cooling, ventilation, hot water and electrical systems all need to work together.
Fluent Energy helps builders make informed mechanical and electrification decisions based on the actual performance requirements of the home.
The House Is a System
Every part of a high-performance home affects the others. Improving the building envelope reduces heating and cooling demand. Lower loads can mean smaller equipment, lower operating costs and more opportunities to electrify the home efficiently.
Better Envelope → Lower Loads → Right-Sized Equipment → Better Performance
1. Building Envelope
Reduce demand at the source.
↓
2. Heating & Cooling
Match equipment to the home’s loads.
↓
3. Ventilation
Provide controlled fresh air and exhaust.
↓
4. Hot Water
Plan efficient domestic hot water.
↓
5. Electrical Loads
Coordinate capacity and load management.
MECHANICAL SYSTEMS
The Systems Behind a High-Performance Home
Mechanical systems should be selected as part of the overall building-performance strategy—not as an afterthought. Early decisions also support your BC Energy Step Code and Net Zero Ready goals.
Heat Pumps
High-efficiency electric heating and cooling designed around the home’s actual heating and cooling requirements.
Air-source heat pumps should be assessed for cold-climate performance and the home’s heating and cooling demand. Heat-loss calculations inform equipment sizing and help avoid oversized equipment.
Heat Pump Water Heaters
Efficient electric domestic hot water can significantly reduce one of the largest energy loads in a modern home.
Heat pump water heaters (HPWH) need careful consideration of equipment location, interaction with conditioned space and energy modelling assumptions.
Heat Recovery Ventilation
Airtight homes need intentional ventilation.
As homes become more airtight, controlled mechanical ventilation supports indoor air quality and energy performance. HRVs—and ERVs where appropriate—coordinate fresh-air distribution, exhaust and heat recovery in airtight construction.
Load Management & Backup Power
Plan electrical service capacity around heat pumps, heat pump water heaters, EV charging and electric cooking, alongside solar, batteries and backup power.
Equipment selection, sequencing and smart load management can help optimize available electrical capacity as these systems work together.
Better Comfort
Consistent temperatures and cleaner indoor air.
Lower Energy Use
High-efficiency systems reduce operating costs.
Future Ready
Support BC Energy Step Code and Net Zero goals.
Expert Guidance
Integrated design for better performance and long-term value.
Right-Sizing Matters
Bigger isn’t always better.
Traditional rules of thumb can result in oversized heating and cooling equipment. Energy modelling and heat-loss calculations provide a clearer picture of what the home actually needs.
A better-performing building envelope can reduce mechanical loads, allowing equipment to operate more efficiently while improving comfort and potentially reducing upfront equipment requirements.
1. Better Building Envelope
Improve the home’s thermal performance.
↓
2. Lower Heating & Cooling Loads
Reduce the demand placed on equipment.
↓
3. Right-Sized Mechanical Equipment
Match equipment to calculated loads.
↓
4. Lower Energy Use + Better Comfort
Bring performance and everyday comfort together.
Planning for an All-Electric Home
Electrification works best when it is considered early in design rather than added one system at a time during construction.
These are planning considerations and options to suit the project, rather than requirements for every home.
Heating & Cooling
Heat pump
Hot Water
Heat pump water heater
Ventilation
HRV / ERV
Cooking
Induction / electric cooking
Transportation
EV charging
Solar Ready
Plan roof layout and electrical infrastructure
Battery Ready
Consider future or immediate energy storage and backup power
Load Management
Coordinate major electrical loads and available service capacity
Start With the Building
Mechanical design starts with understanding the building itself.
Insulation, windows, airtightness, orientation, thermal bridging and solar exposure all influence how much heating and cooling a home actually needs.
Improving the envelope can reduce the demand placed on mechanical systems—and sometimes change what equipment is required altogether.
Envelope Performance
The foundation for lower demand.
+ Energy Modelling
Understand how the proposed home will perform.
+ Mechanical Strategy
Coordinate equipment with the building’s needs.
= Whole-Home Performance
Bring the decisions together as one integrated system.
Where Fluent Energy Fits In
Fluent Energy helps builders evaluate mechanical and electrification decisions as part of the home’s overall energy-performance strategy.
MODEL
Understand expected energy use, heating demand and building performance.
SIZE
Use calculated loads and building-performance data to inform equipment decisions.
COORDINATE
Consider the envelope, mechanical systems and electrification together instead of treating them as separate decisions.
VERIFY
Testing, modelling and performance documentation help confirm that the completed home performs as intended.
Make These Decisions Before Construction
Mechanical and electrical decisions are easier to coordinate—and often less expensive to change—during design.
Bringing your Energy Advisor into the project early can help identify opportunities to improve the envelope, reduce loads, coordinate equipment and plan for electrification before those decisions become expensive changes on site.
Explore our projects and case studies, or find planning resources in Tools & Downloads.
Design Early
Evaluate energy performance before construction begins.
Coordinate Systems
Make sure the envelope, mechanical systems and electrical strategy work together.
Avoid Expensive Changes
Identify potential issues before equipment is ordered or construction is underway.
