As a builder in Brookfield, CT, you’re likely familiar with the growing demand for energy-efficient homes and the regulations that support sustainable construction. Blower door testing has become a crucial component of modern building practices. This guide will explain why blower door testing matters and how it can benefit your construction projects.
What is a Blower Door Test?
A blower door test measures the airtightness of a building by using specialized equipment to identify air leaks. The process involves:
Installing a calibrated fan in an exterior door frame to pressurize or depressurize the building.
Measuring the rate of air infiltration using precise instruments.
Locating areas of air leakage, such as poorly sealed windows, doors, or construction gaps.
The results provide valuable data on the building’s energy efficiency and compliance with local blower door testing codes in Brookfield CT.
