Your Stroma engineer will work alongside your on site team to carry out the Air Tightness Test efficiently and with minimal disruption to other site activities. A UKAS calibrated fan or number of fans is placed within the building envelope in order to carry out a pressurised or depressurised test. Our standard process can be described as follows:
Air Testing (also known as Air Pressure Testing or Air Tightness Testing) is a requirement of the Building Regulations. Part L states that new developments must meet specific air permeability targets to minimise the risk of heat loss and energy inefficiency caused by air leakage. Stroma Built Environment has the world’s largest team of experienced Level 1 and Level 2 Air Tightness Technicians to carry out Air Pressure Testing. Our comprehensive Air Testing services help our clients to determine the development’s air permeability rating so you can meet your carbon reduction and sustainability targets and improve occupier comfort.
The benefits to having an air tight residential property include:
Air Tightness Testing should be undertaken when buildings are virtually complete (usually in RIBA stages 5 and 6) and under calm weather conditions. Depending on the size, complexity and height of the building, either large trailer-mounted fans or smaller electric ‘blower-door-fans’ are used to undertake the air tightness tests to determine any air leakage. Stroma can design and deliver a bespoke service package combining all, or a combination of our Air Tightness and Air Pressure Testing services to facilitate compliance with Part L 2013.
We can help you meet Part L of the Building Regulations and its stringent requirements to reduce CO2 emissions. Part L 2013 currently requires an overall 6% reduction in CO2 emissions and we can help you achieve this through focussed attention on your air barrier strategy and recommendation of a variety of carbon reduction measures.Book your Air Test
Part L2A of the Building Regulations requires every commercial building to undergo Air Tightness Testing and achieve a test result of 10m3/hr2 or less. Stroma Built Environment can provide the necessary Air Permeability and Air Pressure Testing for your commercial or mixed use developments to determine the air leakage and air permeability. Our consultants will work with you from the earliest stages of your commercial development, providing relevant advice and complementary services, such as necessary SBEM Calculations to help your building reach its air tightness targets. We approach Commercial Air Testing projects with a large multi-fan testing system to support accurate collection of air leakage data.
Stroma Built Environment is one of the world’s foremost experts in commercial testing and our engineers have undertaken projects across the globe, including in Asia and South America. Our experience in commercial buildings includes:
For non-domestic air tests, our engineers work closely with colleagues in our Energy department to analyse air leakage targets against the requirements of an SBEM Calculation. Engaging Stroma Built Environment means you can rely on coordinated and efficient support from our Air Tightness Engineers and SBEM Assessors as part of your Part L compliance requirements.Book your Air Test
The Building Regulations require all new build and existing dwellings to pass an Air Test. Stroma Built Environment offers domestic Air Tightness and Air Pressure Testing on all residential buildings to ensure your developments meet their efficiency targets and offer optimum comfort for the occupants. We work with you from an early design stage, offering expert advice and mitigation measures to support your projects in passing our domestic Air Tightness Test the first time. Our clients include major residential housebuilders on multi-plot developments to single plot private residential work. By employing the industry’s largest team of L1 and L2 qualified test engineers we can deliver a flexible and adaptable approach to testing your residential plots.
Clients for Domestic Air Testing tend to also engage our SAP Assessment team to deliver SAP Calculations as part of a Part L compliance pack. Our one plot offer for New Build Certification to Part L, F and G of the Building Regulations starts from only £599 and covers:
Stroma Built Environment has in-house capability to deliver management information and data about a site and project throughout the Pre-Construction phase, into Construction and to support building management Post Completion. Clients can access a web based MI dashboard to view real time information about your projects, including:
Our unique capability to deploy environmental sustainability services throughout the RIBA Plan of Work couple with our data analysis service allows Stroma Built Environment to deliver a holistic compliance package to our Air Testing clients.Book your Air Test
