Agenda

• 1. Update on legislation and the driving forces

affecting the future of ventilation

• 2. Discuss new markets and technologies
• 3. Highlight key considerations
• 4. Give you information to grow your sales

The UK Ventilation Market

What drives sales?

• Legislation
• Homeowners
• Landlords – Social and Private
• Developers

Carbon reduction plan

• Goal to cut the nation’s

carbon emissions by 80%

80% 80% 80% by 2050 by 2050 by 2050 by 2050. . . .

• Biggest issue is dealing

with the carbon emissions generated by the nation’s buildings.

• Domestic dwellings

account for 25%

nation’s carbon output, making them a pivotal part of the Government’s carbon busting plan.

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.

Where does it all go?

Energy efficiency of UK housing stock in the last half century

Number of asthmatics in the last half century

How do we compare to other European countries?

European Legislation

ErP

• 1st stage came into force Jan 2013

125W-500kW fans must comply

• 2nd 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

• 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.

• 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
