Mechanical Energy Recovery
Traditionally, inefficiencies in the building envelope are made up for with large mechanical systems that are expensive and prone to failure. Passive house buildings have extremely low energy demands, saving owners capital upfront and drastically reducing operating costs.
In addition to smaller mechanicals, Passive House buildings feature mechanical ventilation systems with energy recovery also referred to as ERV’s. Quite simply, these units are the lungs of any passive house building, constantly supplying fresh filtered air to the home. ERV’s not only provide higher indoor air quality, but they also provide moisture management, dramatically improving durability and comfort.
