As most developers and builders already know, ventilation became a ‘notifiable work’ as a result of the 2010 revisions to Part F of the Building regulations. Ventilation must now be installed by a competent person and signed off by Building Control.
This means that all ventilation provision in new build properties must now be commissioned by a suitably qualified person resulting in a brand new vocation – the Domestic Ventilation Installer.
Good news for manufacturers who welcomed this following the 2007 BRE Guide: MEV & MVHR system post installation monitoring for SAP Appendix Q which uncovered numerous cases of poorly installed MVHR and MEV systems.
In some instances the units had been fitted so badly that they were not fit for purpose. It may seem like more red tape for developers and builders but ensuring that a ventilation system is installed correctly will save a lot of time, money and hassle in the long term. With today’s push on ensuing homes are built as energy efficient as possible in line with the Code for Sustainable Homes, ventilation plays a very important part of the equation.
EnviroVent have a selection of energy efficient heat recovery systems to suit all your new build requirements.
It is worth noting that a refreshing alternative to heat recovery and MEV Systems for new build projects is an approved BBA PIV unit.
Positive Input Ventilation (PIV) is a whole house ventilation system which works by delivering fresh, filtered air into a property at a continuous rate. To install PIV, the build costs are less than a third in comparison to other ventilation methods, which amounts to significant savings for most budgets. What’s more, PIV can sometimes show better results in SAP than some MVHR systems for domestic new build dwellings.
