Greenfab Blower Door Test: Air Flow

A blower door is a diagnostic tool designed to measure the airtightness of buildings. and to help locate air leakage sites. A blower door consists of a calibrated fan for measuring an airflow rate, and a pressure-sensing device to measure the air pressure created by the fan flow. The combination of pressure and fan-flow measurements are used to determine the building airtightness. The airtightness of a building is useful knowledge when trying to increase energy conservation or decrease indoor air pollution, or control building pressures.

Greenfab’s current project, located in Seattle’s Jackson Place neighborhood, is the first prefab, modular constructed home  targeting LEED for homes Platinum and Built Green 5 Star.

This demonstration home is the brainchild of Greenfab, a provider of sustainable, affordable and well-designed homes and communities with the long-term vision to encourage mainstream use of modular construction to provide healthier homes at a more affordable price point.  Currently under construction, the demonstration home will be open for tours for a limited time upon completion.

As this first Greenfab project continues construction, we are dedicated to updating you often on the process, progress and lessons learned.
