Build Equinox
Demand-controlled ventilation with air-quality sensing built in.
What they're known for
The CERV platform combines ventilation, filtration, sensing, and heat-pump energy recovery for airtight homes.
Build Equinox makes the CERV residential air-management platform for tight, high-performance homes. Rather than running ventilation at one fixed rate, the system monitors indoor conditions including carbon dioxide, volatile organic compounds and particulates, then adjusts ventilation and recirculation around measured demand. The platform combines sensing, filtration and heat-pump energy recovery in one system. It is a useful example of residential mechanical ventilation moving from fixed equipment toward responsive environmental control.
Credentials
