risks. In addition, indoor air can contain volatile organic compounds (VOCs) from household products, which can lead to long term health problems.


One of the challenges in implementing mechanical ventilation systems is managing noise levels. Updated guidelines in Approved Document F address acoustic performance, providing a framework for reducing noise in ventilation systems. Selecting ventilation systems that are proven to operate at very low noise levels can help maintain a peaceful indoor environment while ensuring adequate ventilation.


ENERGY EFFICIENCY & VENTILATION With the UK government’s commitment to achieving net zero emissions, energy effi ciency has become a focal point in Building Regulations. Approved Document F emphasises that ventilation systems must not compromise the overall energy effi ciency of a building Because of the regulation changes, housebuilders and developers are taking a much more proactive approach to ventilation. This includes working closely with ventilation manufacturers early on in the design of the buildings, ensuring they can achieve compliance with the new regulations, both now and in the future.


SELECTING THE RIGHT SYSTEMS Choosing the right ventilation system is vital for compliance and for good indoor air uality that benefi ts the health of occupants. Mechanical Ventilation with Heat


Recovery (MVHR) systems are increasingly being specifi ed to meet Building Regulations in new and refurbished homes, which not only provides a high level of indoor air quality but also recovers heat from extracted air, therefore saving energy. In addition, continuous Mechanical Extract Ventilation (MEV), which are ideal for dwellings with low air permeability as it ensures consistent air exchange. Positive Input Ventilation (PIV) systems are also extremely effective in managing humidity levels and helping to prevent condensation and mould which can be easily retrofi tted into most properties Housebuilders can ensure compliance


with Part O of the Building Regulations (Overheating) by selecting effective ventilation solutions designed to remove excess heat and promote thermal comfort within dwellings.


CORRECT COMMISSIONING


The commissioning process is crucial for ensuring that ventilation systems operate as intended. This involves testing and


adusting the system to meet the specifi ed airfl ow rates and performance criteria In addition, there is a need to maintain detailed records of the commissioning process, including any measurements and adjustments made.


Educating homeowners on the operation and maintenance of ventilation systems can also enhance their effectiveness and longevity.


There are many ways that ventilation manufacturers can work with housebuilders and developers to ensure they can achieve compliance with the latest legislation. This includes the delivery of CPDs, workshops and webinars on Approved Document F, L and O compliance. There is also an opportunity for onsite contractor toolbox talks, onsite installation support and best practice compliance training.


Some manufacturers also provide ventilation system design support for a project, which includes supplying detailed technical drawings to fully comply with your project needs, the latest building regulations and SAP requirements. This can remove some of the complexities of ventilation system design for housebuilders and contractors.
