Vent-Axia Hosts Webinar on How Building Regulations Will Affect Ventilation in New Build Homes

  • 22 Feb 2022

Leading ventilation manufacturer Vent-Axia is to host a webinar, ‘Domestic Legislation for Ventilation’, on the recently launched Building Regulations. Aimed at housebuilders, M&E contractors, consultants and architects, the webinar will inform delegates of the recent changes to the legislation and explain how they will affect ventilation in New Build homes. 

Published on 15th December 2021, the Building Regulations bring significant changes for housebuilders with the new amended Part L (Conservation of Fuel and Power), set to help the UK deliver Net Zero with a reduction of almost a third less carbon for new build homes. However, increasingly airtight homes must consider indoor air quality (IAQ) to protect the wellbeing of inhabitants and so the new Part F (Means of Ventilation) sets out to increase ventilation rates and will drive adoption of low carbon ventilation as an industry standard. 

This essential webinar ‘Domestic Legislation for Ventilation’ will be an hour long and will take place on the following dates:

 – Wednesday 9th March 2022 at 12 noon

 – Wednesday 16th March 2022 at 12 noon

The webinar will be presented by Vent-Axia’s Product Manager Joe Tse and the company’s Product and Marketing Director Richard Paine. The webinar will explain the important changes to the legislation covering both Part L and F of the Building Regulations, with a particular detailed focus on Part F.

Other topics it will incudes are: an explanation of the ventilation solutions available for new build homes; design considerations such as noise and ingress of pollutants; as well as installation and commissioning. There will also be the option to ask questions at the end. To sign up click here.

Joe Tse, Product Manager at Vent-Axia (below), comments: “We welcome the new Building Regulations, which is set to help the UK deliver Net Zero with a reduction of almost a third less carbon for new homes.

“However, the cut in carbon emissions in Part L sets a challenge for housebuilders making it vital to increase ventilation in ever more airtight homes. 

“At Vent-Axia we are keen to help housebuilders comply with the Regulations by explaining the changes and how to meet them with our webinar offering the ideal opportunity to find out about the new legislation and to ask questions on how this might affect ventilation in their properties.”

For New Build residential homes, ventilation has increased in Part F to support the safety of residents with an overall move to more advanced ventilation solutions, such as Mechanical Ventilation with Heat Recovery (MVHR) and Continuous Mechanical Extract Ventilation instead of traditional Intermittent Extract Ventilation (now referred to as Natural Ventilation throughout the document).

Natural Ventilation is now only suitable for dwellings with a design air permeability higher than 5 m3/(m2·h) meaning many new build dwellings will be out of scope of this technology.

With the new Regulations, all properties must be air tightness tested and if a dwelling designed with natural ventilation becomes ‘highly airtight’ following testing expert advice should be sought and a continuous mechanical extract ventilation system should be installed. However, benefit within SAP may not be recognized if technology is not correctly selected. 

With the increased airtightness of buildings and increased minimum whole dwelling ventilation rates for continuous mechanical extract units, higher performing options are needed.

Here, housebuilders look to favour continuous mechanical extract units that offer a 125mm diameter spigot model since the larger surface area will allow greater airflow through the fan at a much lower noise level and SFP.

This means fewer fans are required to achieve whole house ventilation rates. The new Regulations also place emphasis on increased ventilation and installation compliance to ensure ventilation operates as specified.

For New Build residential Vent-Axia has launched the award-winning Multivent MEV family, a new range of mechanical extract ventilation (MEV) and decentralised MEV (dMEV) designed to provide a simple and effective solution to help housebuilders meet the Future Homes Standard.

The new Multivent MEV family is the ideal solution, helping housebuilders meet DER requirements through its market-leading energy efficiency and improving IAQ for homeowners.

The complementary other half of the Multivent family is Vent-Axia’s Lo-Carbon NBR dMEV, a range of continuous running, constant volume dMEV units. This includes a unique 125mm option, which further improves DER by improving efficiency and lowering noise and is ideal to meet the new Part F requirements.
