Understanding the Blower Door Test

A blower door test is an essential process to measure the airtightness of a home. This test is commonly required for achieving energy efficiency certifications or meeting Florida’s building code requirements. By quantifying the amount of air leakage in a home, blower door tests provide valuable insights into energy performance and opportunities for improvement.

Energy Efficiency

A tighter home reduces the workload on heating and cooling systems, leading to lower utility bills.

Building Compliance

Florida’s Energy Conservation Code mandates blower door tests in many scenarios to ensure code compliance.

Incentives

Many programs, like the Weatherization Assistance Program (WAP), offer monetary rewards for homes that meet air leakage standards.

Home Value

A certified energy-efficient home is more attractive to buyers and can lead to mortgage inducements.

How the Blower Door Test Works

The blower door test is a straightforward yet highly effective process used to measure a home’s air leakage and energy efficiency. By simulating pressure changes, the test identifies how tightly a home is sealed and highlights areas for potential improvement. Here’s a step-by-step breakdown of how it’s conducted:

01

Door Setup

A temporary frame is placed in an exterior door, fitted with a specialized fan at the bottom. This frame is covered with vinyl or canvas designed specifically for blower door testing.

02

Pressure Control
The fan pressurizes or depressurizes the home by forcing air in or out. This step creates a controlled environment to measure air movement and identify potential leaks.

03

Data Collection
A pressure gauge (manometer) is used to measure the differences in air pressure, converting this data into airflow measurements to determine the home’s overall air leakage.
