Specialists In UK Passivhaus Air Tightness Testing

Air tightness Testing at a PassivhausDeveloped in Germany in the 1990s, the Passivhaus is currently the fastest growing energy performance standard in the world. Passivhaus dwellings are designed with ultimate energy efficiency and thermal performance in mind.

The purpose is to develop a dwelling that has an excelled thermal performance, coupled with exceptional air tightness and heating. The high standards of build extend to the standard of less than 0.6 ACH that all Passivhaus properties must adhere to, too.

At Tophouse Assessments, we specialise in providing comprehensive air tightness and pressure testing services at Passivhaus properties across Kent, London and the South East. We will give you the advice and guidance needed to ensure that your property reaches the target goal of 0.6 ACH.

1st Fix Stage

We will conduct air tightness testing at the very first fix stage to ascertain the performance and whether it will achieve the ultimate goal of less than 0.6 ACH. During this stage, we will also calculate the average of depressurisation and pressurisation tests.

The volume will need to be calculated by the architect to the Passivhaus standard before we arrive for this initial stage.

On Completion

At the completion of the build, just before it is ready to be occupied, we will conduct another set of air pressure and tightness testing to the rigorous Passivhaus standard. During this testing, we will calculate the average of both pressurisation and depressurisation tests and then ensure that the air leakage complies with Part L of the Building Regulations and satisfied building control.

Based in Chatham, we work throughout Kent, London and the Home Counties, providing building companies and architects with the most reliable, accurate and specialist SAP calculations and EnerPHit air leakage testing services.

We have recently undertaken EnerPHit air leakage testing projects for clients in Gillingham, Rochester, Canterbury, Dover, Deal, Folkestone, Maidstone, Ashford, Tunbridge Wells, Tonbridge, Sevenoaks, Bromley, Ramsgate, Orpington, Dartford, Bexleyheath, Rainham, Aylesford, Chatham, Strood, Brighton, Chelmsford, Colchester, Reigate, Croydon, Epsom and Cambridge.
