Ventilation Testing and Commissioning

ventilation-testing-and-commissioning

Part F of the Building Regulations (2010) introduced the requirement to test the practical performance of ventilation systems in new dwellings. Since RJ Acoustics also offers air tightness and sound insulation testing, we are well placed to carry out ventilation testing whilst on site.

We have experienced engineers who have completed hundreds of tests across the country. Our engineers are all fully BPEC accredited, having completed the Domestic Ventilation course.

What is a Ventilation Test?

Ventilation testing and ventilation commissioning are actually two different things. Testing refers to extractor fans, like you would find in a toilet, bathroom or kitchen. These are tested to see how much air they extract. Commissioning refers to more complicated ventilation systems, such as Mechanical Ventilation Heat Recovery (MVHR). These need to be balanced, to make sure the correct amount of air is either being extracted from or supplied to every room in the house.

The tests must be undertaken using UKAS calibrated equipment and should be conducted by an engineer registered with a competent scheme with respect to domestic ventilation technologies. All RJ Acoustics engineers have successfully completed the BPEC Domestic Ventilation course and all of our equipment is fully UKAS calibrated

As part of our service, we offer our expertise from the very start of any project to give your property the best chance of passing

Why do Properties need Ventilation System Testing?

Ventilation is incredibly important in all dwellings. A property without sufficient ventilation is far more likely to have problems with mould, condensation and damp. In addition to this, Pollutants in your home’s air can cause poor indoor air quality, which in turn may cause dizziness and headaches, plus aggravate allergies and asthma. With a sufficient ventilation system, you’re ensuring a good supply of fresh air and improving yours and your dwelling’s well-being.

Types of Ventilation Systems

There are 4 different types recognised in building regulations part F. Testing and/or commissioning has to be carried out on Types 1, 3 and 4. The Types are:

Type 1: Intermittent extract fans with background ventilators – This is what is found in most houses – Extractor fans in kitchens, toilets and bathrooms and trickle ventilators on the windows.

Type 2: Passive Stack Ventilation – This is very rarely seen. It is a system which uses a combination of cross ventilation, buoyancy (warm air rising) and the venturi effect to ventilate. It is rarely used because it’s very much weather dependant.

Type 3: Mechanical Extract Ventilation (MEV) – This can either be a whole house system or a localise system for specific rooms. Multiple ducts will run from a constantly running unit to wet rooms (kitchen, WC, bathroom) continuously extracting stale air. When these rooms are in use, the system will boost up to extract a larger volume of air

Type 4: Mechanical Ventilation Heat Recovery (MVHR) – This is similar to Type 3, except that it also supplies fresh air to all non-wet rooms (bedrooms, dining room, living room). The heat from the stale extracted air is kept in the central unit and used to heat the fresh air from outside before it is supplied to the house.

What is needed for a Building Ventilation Test?

In order to complete these tests, we will need the SAP calculations, details of the property’s ventilation system and its design, and floor plans of the dwelling. In addition, the system in question will need to be fully installed and operational (read more in our FAQs).
