Air Pressure Testing in residential and commercial buildings

Air tightness testing, air pressure testing, or air leakage testing is a skilled method of determining uncontrolled airflow, air leakage, and unwanted drafts at a property that may result in heat loss. As such, a dwelling would not be deemed environmentally friendly and could prove expensive to run if it did not pass the test.

Since April 2006, new build and conversion properties have been required by law to comply with Part L of the Building Regulations. This states that the properties must undergo air tightness testing to ensure that they meet the standards of energy efficiency and do not have a high percentage of air permeability throughout the home.

By thoroughly tracing and monitoring air pressure and leakage, such heat loss can be eradicated along with the risk of CO2 emissions; a key principle of modern building regulations.

Depending on what type of property you have and the amount of homes in a development, the process to air tightness testing can differ slightly. Air pressure testing is only undertaken in a portion of homes within a development, and if they all pass the test then there is no need for further tests to be undertaken.

Discover our guide to common sources of air leakage.

Our process for measuring air pressure in a building

Air Leakage in buildings is measured by installing a large fan temporarily on-site to measure the pressure differential across the envelope of the property. To complete the test, we will book our visit at a time to suit you, and we require an empty building.

Throughout the air testing, the fan is used to gradually increase and decrease the pressure, which allows for a range of pressure and environmental readings to take place. The differential pressure is recorded between 25-70Pa (Pa is the unit of measurement for air pressure – ‘pascal’).

50Pa is the required air flow differential, so the total airflow needed to achieve this is calculated and divided by the total building envelope. This results in a leakage rate (m3/h/m2@50Pa).
Once we have completed the air tightness test, we will leave the building as we found it and work to prepare your report in a timely manner.

FREQUENTLY ASKED QUESTIONS

Although air tightness testing cannot be undertaken until the property or properties are completed, instructing a qualified tester should be considered at the beginning of the construction process at the planning stage.

This is because if a knowledgeable energy company, such as Falcon Energy, is consulted from the beginning, then we can help to suggest best practices for energy efficiency at an earlier stage. This ensures that once the dwelling is complete, it has a far higher chance of passing and achieving compliance with building control.

As soon as the build is complete, then air tightness testing can begin. To find out more about the process involved with air tightness testing, read our blog

To reduce air leakage of a building and to lower the results of the air tightness test. This reduces the amount of energy required to maintain comfort levels and in turn, reduces carbon dioxide emissions from heating.

Having an airtight home is both environmentally and financially efficient and saves homeowners money in the long term.

Proving the air tightness standard of a building is now required under Part L of the Building Regulations. Domestic energy accounts for more than 25% of the UK’s CO2 emissions, which the UK Government aims to reduce overall.

As a result, an air test is an important certification for developers in new build projects.

They’re the opposite of controlled air flow that you might experience with purpose built ventilators that result in desired air flow.

Air leakage paths are uncontrolled air flows and are undesired. These instances can occur through cracks in a building’s fabric, or even gaps.

Once these paths are discovered, they should be fixed to reduce or stop air leakage.

 Trustindex verifies that the original source of the review is Google. I needed an EPC certificate to market my property and decided to book it with Falcon energy. Josie arrived a couple of days later and completed the EPC in a very efficient manner. She was very friendly, professional and knowledgeable and she explained the whole process to me. Thank you so much. I wouldn't hesitate to use this company in the future.

My enquiry was dealt with quickly and efficiently. Jose arrived at the property at the agreed time, she was very polite, friendly and efficient. Excellent service all round. Good price, paperwork received immediately after receiving payment. I would definitely recommend.

 Trustindex verifies that the original source of the review is Google. This is the first EPC I have done for maybe 12 years so not very experienced however I was highly impressed how quickly this all happened. Enquiried, surveyed, paid and issued new certificate/posted to Gov website in less than 24 hours. Josie who did the survey was communicative, thorough, polite and very helpful when I had some questions. Instead of driving away and calling me back she got the answers she needed, knocked on my door again to clear the issue up, did a bit more survey work and that was it. So much more convenient and efficient than having to arrange another visit. Cost-wise the same as another quote I had.

 Trustindex verifies that the original source of the review is Google. After dealing with a bank who required an EPC at the last minute, Josie was fantastic. She was able to visit the property quickly, get the certificate provided promptly, and all for a fair price.

Would have no hesitation in recommending her and Falcon Energy.

 Trustindex verifies that the original source of the review is Google. I've worked with Falcon Energy for a number of years now for our EPC requirements as a housing association although that is only a small part of their service offering, their customer service and communication is second to none and are often very accommodating when quick turnaround times are needed. Highly Recommend!
