Passive homes are designed to be ultra-energy efficient, reducing the need for artificial heating and cooling. A critical aspect of this design strategy is achieving a high level of airtightness. This guide will delve into the airtightness goals for passive homes, explaining why they are important, and how they can be achieved.
Before we dive into the specifics, let’s have a look at resilience in passive house design, which provides a comprehensive overview of the principles behind these energy-efficient structures.
Understanding the Importance of Airtightness
Airtightness is a key factor in passive house design. It prevents uncontrolled air leakage, which can lead to energy loss and discomfort for the occupants. Achieving a high level of airtightness requires careful planning and execution during the construction process.
Setting Airtightness Goals
For a house to be classified as a passive house, it must meet specific airtightness standards. These standards are set by the Passive House Institute and are measured using the air changes per hour (ACH) metric. The current target is 0.6 ACH at 50 Pascals pressure during a blower door test. This level of airtightness ensures optimal energy efficiency and comfort.
How to Achieve Airtightness Targets
Achieving the required level of airtightness involves meticulous attention to detail during the design and construction phases. It requires the use of quality materials and techniques, such as airtight membranes, careful sealing of all joints and penetrations, and thorough testing to identify and rectify any leaks.

As we near the conclusion of this guide, it’s important to highlight that achieving airtightness targets for passive homes is a challenging but rewarding endeavour. It not only contributes to the energy efficiency of the home but also enhances the comfort of its occupants.
