Assessment Procedure) may lower the DER by 7-8 per cent. Another reason for the increasing adoption of
MVHR by the new build sector is the updated ErP Directive, which is encouraging a move to a more systems-based approach to ventilation. It was first introduced in 2013 and the second stage of the legislation which has recently been released, focuses on ventilation units over 30 W. This mainly impacts on mechanical extract
ventilation and MVHR systems and requires all ventilation units, excepting dual use versions, to be equipped with a multi-speed or variable speed drive. In addition, all bi-directional units are required to have a thermal bypass facility as an essential part of the design criteria, which prevents warm air being recovered in warmer weather. Building designers are recognising that MVHR helps them to cost effectively contribute
towards minimising CO2 emissions as required by Building Regulations. With MVHR, the incoming air is filtered, improving internal air quality and it also negates the need for window trickle vents. There is a rise in demand from the new build
sector for MVHR systems that are ever more effi- cient and take advantage of the latest technology to bring functional benefits to users. Recovering over 90 per cent of the heat that would normally be lost to the outside via trickle vents or extract
fans, and feeding it back into the house as warm fresh air, ensures that developers are able to reduce the overall energy requirement of the building. There are obvious benefits to home- owners looking to reduce their energy bills. Systems can also offer high energy efficiency and feature a summer bypass facility, making them fully compliant with the ErP Directive for venti- lation units. Whole house heat recovery units were specif-
ically designed for new homes and are very cost effective for the housebuilder and offer low run- ning costs for the homeowner. The units feature an automatic summer bypass facility, which con- tributes to an improved comfort level in summer.
Correct installation
A key factor in the effectiveness of ventilation systems, including MVHR and PIV, is correct installation by trained and experienced installers, plus the provision of high quality user informa- tion and guidance for homeowners. Since 2010, with the revision of Building
Regulations Approved Document F, domestic ventilation became notifiable work. More house- builders are therefore putting their electrical and heating engineers forward for BPEC training. Research shows that only 8 per cent of UK
residents currently have a continuous mechan- ical ventilation system in place, which is

worrying low when you consider the scale of the issue. Installing mechanical ventilation systems is the
most effective way that the new build sector can meet the increasingly stringent legislation in order to be able to provide a constant supply of clean air and reduce humidity levels. The trend towards fitting MVHR and PIV systems into new homes therefore looks set to continue as their efficiency and performance become more widely recognised.

A new eight-page brochure and online animation from brick support specialist, Ancon, show just how simple it is to create suspended masonry soffits on virtually any brick building, regardless of soffit dimensions, brick type or bond pattern. The animated installation video takes the viewer step by step through the process from initial fixing of the Ancon
MDC Nexus support system through the bolting on of the lightweight Nexus brick faced soffit unit and how it can be adjusted and levelled in all three planes, to the final pointing of the brick slip face.
