Air Pressure Testing
Air pressure testing or blower door testing, measures a building’s airtightness to identify air leaks. This ensures compliance with energy efficiency standards and building regulations. Essential for property developers, architects, landlords and real estate managers, it supports energy performance certifications (EPCs) and sustainability goals.
At Focus 360 Energy, we provide expert air pressure testing to ensure compliance, improve energy efficiency and reduce operational costs. Our certified team uses advanced equipment for accurate assessments of residential and commercial properties.
Why Air Pressure testing is essential for your property
Air pressure testing is a critical tool in the building industry. The results can affect everything from energy performance ratings to occupant comfort and safety.
- Compliance with Building Regulations
Building regulations in many regions, including the UK, mandate airtightness testing to ensure properties are energy efficient. Failure to meet these requirements can result in fines, delays and complications in obtaining occupancy certificates. Whether you’re building a new structure or refurbishing an existing one, air pressure testing helps ensure your project complies with all legal requirements. - Identifying Energy Leaks
Air leakage can lead to significant energy loss, resulting in higher heating and cooling costs. Air pressure testing allows property owners and developers to identify weak spots in a building’s structure, such as gaps around windows, doors and vents, where air may escape. By addressing these leaks, you can significantly improve energy efficiency and lower utility bills. - Improving Building Performance
Testing the air permeability of a building is integral to understanding its overall performance. An airtight building saves energy and enhances indoor comfort by maintaining consistent temperatures and reducing drafts. This leads to a more comfortable living or working

How Air Pressure testing works
Air pressure testing is a straightforward process, but it requires specialised equipment and expertise. Here’s a breakdown of how the test is typically conducted:
- Preparing the Building
The test begins by ensuring all windows and doors are closed and ventilation systems are temporarily sealed. This creates a controlled environment in which air pressure can be measured accurately. - Setting Up the Blower Door
A blower door unit is installed in an external doorway. This unit uses a powerful fan to depressurise the building, creating a difference between the indoor and outdoor air pressure. The fan’s speed and airflow are adjusted to measure the building’s air permeability. - Conducting the Test
Once the fan is activated, air will flow through any gaps or leaks in the building envelope. The test measures the amount of air that escapes or enters, determining the airtightness of the building. The results are recorded and the air changes per hour (ACH) are calculated. - Analysing Results and Recommendations
After the test, the results are analysed. If excessive air leakage is detected, the team provides recommendations for addressing the leaks, such as adding sealants or improving insulation. These solutions help improve energy efficiency and ensure compliance with building regulations.
Benefits of Air Pressure Testing
Air pressure testing offers several key benefits, from improved energy efficiency to enhanced building performance. Here’s how it can make a difference for your property:
- Energy Efficiency
By identifying and sealing air leaks, air pressure testing helps significantly reduce energy consumption. An airtight building is easier to heat and cool, resulting in lower energy bills and reduced environmental impact. - Improved Comfort
Air pressure testing also ensures a more comfortable living or working environment. Sealing gaps and cracks in the building prevents drafts, noise and moisture penetration, which can contribute to discomfort and health problems. - Faster Project Completion
Ensuring that your building is airtight from the outset can speed up the certification process. By passing air pressure tests, you can avoid delays and get your building ready for occupancy sooner, improving project timelines and reducing costs. - Sustainability
Sustainability is a growing concern for property developers and managers. Implementing air pressure testing as part of your building strategy helps you meet green building standards and ensures that the property is more environmentally friendly. It can also improve your building’s EPC rating, which is an increasingly important factor for tenants and buyers.
Who Needs Air Pressure Testing?
Air pressure testing is essential for a wide range of property professionals and owners:
- Property Developers
Developers building new residential or commercial properties must ensure their buildings meet the required air-tightness standards. Air pressure testing is an integral part of the building’s compliance and certification process. - Architects and Designers
Architects must design buildings that meet energy efficiency standards. By collaborating with energy assessors who conduct air pressure tests, architects can fine-tune their designs to ensure they achieve optimal airtightness. - Landlords and Property Managers
Landlords and property managers must ensure their buildings meet minimum energy performance standards. Air pressure testing helps identify and address inefficiencies that could increase operational costs and reduce tenant satisfaction. - Commercial Property Owners
Commercial property owners benefit from air pressure testing by ensuring that their buildings comply with energy efficiency standards. A well-sealed building can attract tenants who are increasingly looking for sustainable, cost-effective spaces.
