- Particulate-sensing filtration
- Predictive airflow algorithms
System Performance Metrics:
| Component | Energy Savings | Air Changes/Hour | Maintenance Needs |
|---|---|---|---|
| Passive Stack | 100% | 3-5 | None |
| Heat Recovery | 50-70% | 8-12 | Quarterly |
| Smart Assist | 30-50% | 15-30 | Biannual |
These integrated systems represent the new benchmark in sustainable ventilation.
What is the future of green building?
The construction industry's transformation is accelerating. Tomorrow's buildings will function more like living organisms than static structures.
The future of green building points to regenerative designs1 that improve environments, net-positive energy structures, and fully circular material flows. Ventilation will evolve into building respiration systems by 2030.
