Double-glazed windows are the most common for energy-efficiency and are commonly used in standard construction. However, installing three-glazed windows will provide with you with a higher energy-efficiency rate.
It’s necessary that mechanical ventilation is used to control moisture levels and maintain a healthy air flow due to the airtight nature of passive homes. The vent systems usually contain energy-recovery systems that outgoing air will cool or heat air incoming air.
