During an in-depth assessment, an auditor will also run tests to measure airtightness in the building. A common method is a blower door test, which involves installing a fan in an exterior doorway to pull air out of the house, lowering the air pressure inside to help detect air leakage. ...
pressure drop, neck velocity, and noise criteria. These attributes help in the proper maintenance of the system.The ductwork design should be attained using one of the efficient methods, such as the static regain method. It is recommended to use computerized ductwork design analysis...
in the system static pressure, the zone thermostat won’t be able to sense the sudden increase of airflow. However, the pressure independent unit will deliver the required air volume to the room, even if the supply static pressure increases. A flow sensor is installed in the supply airflow...
The following enhancements coming in version 2 will help achieve optimal indoor air quality: Heating and cooling (HAC) equipment: For Gold level, all HAC equipment and ductwork must be located within the thermal and air boundary. There are several practical exceptions to this requirement, such as...
