Building Regulations
Part F building regs govern the ventilations requirements and as per these regulations it is a requirement to test ventilation systems in new build properties. Part F volume 1 applies to dwellings, while volume 2 applies to all buildings other than dwellings.
Under Part F ventilation systems are divided into separate categories labelled as Systems:
- System 1 – Intermittent extract fans with background ventilators
- System 2 – Passive stack ventilation
- System 3 – Mechanical Extract Ventilation
- System 4 – Mechanical Ventilation with Heat Recovery (MVHR)
Each system has its own benefits depending on build type of your property and occupant requirements.
Why choose SEES?
- Accredited members of the Air Tightness Testing and Measuring Association (ATTMA)
- Coverage all over the UK with no mileage charges
- We provide practical information & guidance prior to visit to ensure best results possible
- If required, we can provide same day certificates
- We use the latest high power blower door fan systems
These calculations take into account the carbon emissions generated from operating the building and are then used to produce a non-domestic EPC which indicates the energy efficiency rating of the property from A to G.
How do we help?
We provide coverage all over the UK and our expert testers use UKAS calibrated equipment as is defined by Part F regulations. Ventilation testing can usually be coupled with airtightness testing, which would also warrant a discounted price on both services.
All mechanical ventilation fans should be tested for airflow rate. Any of the following may fall under this category:
- Intermittent extract fans.
- Cooker hoods.
- Continuous extract fans or terminals.
- Continuous supply of fans or terminals.
A calibrated air flow device with a proprietary hood should be used to measure the airflow rates at each room terminal.
