Image
In this ventilation configuration, an air handler provides outside air at the same rate as the air being exhausted from a bathroom fan; local kitchen exhaust has a dedicated makeup air intake; dehumidification is provided separately
Image
In tropical climates such as Puerto Rico, some houses have metal jalousie louvers instead of glass windows; metal jalousies look like shutters, but typically offer little debris resistance.

Image
Individual metering or submetering of each unit allows residents to understand and better manage their water use.
Image
Image
Image
Indoor measurement of a whole house mechanical ventilation system with a pressure balancing flowhood provides a sheltered location for measuring airflow
