Approved Documents
Approved Documents (ADs) are government guidance on how to meet the legal requirements set out in the Building Regulations. ADs are intended to provide guidance for some of the more common building situations. However, there may well be alternative ways of achieving compliance with the requirements. Thus there is no obligation to adopt any particular solution contained in an AD if you prefer to meet the relevant legal requirement in some other way. (Source: CIBSE)
highly efficient ventilation systems like MVHR, which require trained competent installers. Heat recovery systems are more complex to install
than single fan solutions and need to be fitted correctly to ensure performance, which is key when it comes to lowering carbon emissions. Currently there is a shortage of skilled installers trained to fit MVHR, and without contractors undergoing training now, we look set for a skills gap. To help with this, Vent-Axia offers the BEAMA CPD
seminar to try to support the rapid rise in demand for MVHR systems, and is also working to develop a competency framework with the industry to help deliver a longer-term, better-integrated training solution. To ensure the installed performance of MVHR units
meets the requirements of Part F, contractors must be rigorous about key areas of each and every installation – the product, ductwork, the electrical fixing, system balancing, control and maintenance. Here, best practice is important to ensure not only that MVHR systems are installed correctly, but that they are also maintained correctly. In countries where MVHR is an established technology, contractors are heavily involved in after-sales maintenance, which can potentially offer companies a new and successful revenue stream. With the Code for Sustainable Homes and the Building Regulations mapping out the coalition government’s hopes for future carbon reductions, we need to prepare now for the journey to zero carbon homes in 2016. As homes become inevitably more airtight to meet changes to the regulations, it will be essential to use energy efficient ventilation, such as MVHR. But meeting the challenge of zero carbon homes is about more than just making a product selection; we also need to work together to consider correct specification, commissioning and installed performance of products, ongoing maintenance and system design, which are all necessary to meet our shared goal of achieving good low carbon ventilation. l
