The Confluence Building Castlegar,BC - High-Performance Ventilation Enabling Passive House Success
The Confluence Building demonstrates how high-performance ventilation enables Passive House success in a civic facility. By integrating Swegon GOLD air handling units, the project achieves exceptional indoor air quality, energy efficiency, and year-round occupant comfort while significantly reducing heating and cooling demand.
Project Overview:
Project Goal: Deliver exceptional indoor air quality while minimizing energy consumption through high-efficiency ventilation.
- Purpose of the building
- Passive House design goals
- Why ventilation is central to performance
- Importance of energy recovery
The Challenges:
Passive House buildings dramatically reduce heating and cooling loads but that shifts complexity onto the ventilation system. The system needed to:
- Deliver continuous outdoor air in an ultra-airtight envelope
- Recover maximum energy from exhaust air
- Maintain stable indoor conditions year-round
- Support multiple occupancy zones
- Operate quietly in a civic environment
The Swegon Solution:
Swegon GOLD energy recovery ventilation units form the backbone of the building's environmental strategy, delivering continuous fresh air with exceptional heat recovery and intelligent controls.
Key Advantages:
High-Efficiency Heat Recovery
Captures and reuses heat from exhaust air, significantly reducing heating demand and supporting Passive House performance.
Balanced Continuous Ventilation
Provides filtered outdoor air 24/7 while maintaining neutral building pressure and eliminating drafts.
Flexible Zoning
Multiple units independently serve different occupancy zones, ensuring consistent comfort throughout the facility.
Integrated Controls
Factory-installed controls simplify commissioning and maintain optimal system performance.
Quiet Operation
Low sound levels create comfortable office and public environments.
Performance Outcomes:
Energy Efficiency
Reduced heating & cooling demand
Indoor Air Quality
Continuous filtered outdoor air
Occupant Comfort
Quiet, draft-free spaces
Conclusion:
The Confluence demonstrates how Swegon solutions enable Passive House performance by delivering energy efficiency, indoor air quality, and occupant comfort in a single integrated system.
As buildings move toward lower carbon and higher performance, ventilation becomes the cornerstone—and Swegon delivers.
