UK legislation driving greater airtightness
UK Legislation New Target Emission Rate (TER) representing a 6% improvement over the previous regulations. Encouraging a focus on improved airtightness and with it the requirement for adequate ventilation.

European Legislation
ErP • 1 st stage came into force Jan 2013 125W-500kW fans must comply • 2 nd stage Jan 2015 Focussing on domestic bidirectional fans and unidirectional fans over 30W. • Higher levels of localised control will be favoured e.g. sensors in individual rooms • Specific requirements for certain products e.g. All Heat Recovery Units must have thermal summer bypass
A ‘systems’ approach Creating a shift in ventilation methods towards the use of systems
Part F System 3: MEV
Part F System 4: MVHR 24,000 MVHR fan units were installed in the UK in 2012, mostly in new homes and this is expected to continue* *BEAMA
Heat Recovery in Europe
Considerations for MVHR best practice 1. Design • System Design – competent designer in accordance with manufacturer’s guidance to comply with legislation. Future-proof for BIM • Type of MVHR unit – suitable for application, user functionality and expected occupancy • Location – ease of access, ductwork in unheated spaces should be insulated • Noise – Careful consideration to size and performance of the system
2. Installation & commissioning • Support from manufacturers who are partnering with competent installers • Comply with Domestic Ventilation Compliance Guide
Importance of Installation Practice to System Performance Do Do Do Do � Ensure ducts take the path of least resistance to maintain system efficiency. Reducing amount of bends and flexible duct in the duct routes will help maintain performance. Flat ducts of an appropriate size for the system can be used instead of rigid round duct Don't Don't Don't Don't x Allow ducts to be unsupported x Introduce more bends than necessary Here, the system is using too much flexible duct and has sharp bends in close proximity, which will greatly affect performance
Retrofit T o achieve government’s target 2,500 retrofits have to take place each day, this works out at 333 completions per hour for the next 30 years! 25 million homes 25 million homes 25 million homes 25 million homes
5 million of them social housing
20 million private housing
Driving demand for retrofit ventilation methods Single Room Heat Recovery Units offer a practical green solution to replace old, inefficient extract fans. Recovers heat that would normally be lost through extraction. The unit uses the ‘recovered heat’ to warm fresh, clean air that it delivers back into the room .
Sustainable design T o have confidence in the product need to consider: � Long lifecycles and warranty periods � Reliability � User functionality � Ease of maintenance
Summary • Stringent airtightness in new homes driving the need for adequate ventilation. Electrical distributors should have a greater awareness of ventilation and the changes • New legislation is driving improvements in fan industry and steering future ventilation methods towards a ‘systems’ approach presenting new opportunities for Electrical Distributors • Electrical Distributors should be trained to offer a solution- driven approach to customers rather than just box-shifting exercise In order to ventilate right, you need to: � Design right � Install right � Maintain right
