Masterclass: MVHR - making ventilation systems work

Date: 19 June 2013 Time: Introductory session 11.00 - 13.00 | Masterclass 14.00 - 17.00
Location: Callum Walker Energy Centre, Rosyth, Fife Cost: Masterclass: PHT Members £100+VAT; Non-members £150 +VAT | Introductory session: £50 + VAT

When designing to the Passivhaus standard, Mechanical Ventilation Systems with Heat Recovery (MVHR) are essential to achieve the required performance levels by providing fresh air supply with minimal heat-loss. MVHR systems are also increasingly specified in more conventional buildings due to increased air-tightness standards.

This Masterclass, limited to around 20 participants focuses on what to look out for when designing, specifying, installing and commissioning MVHR units. The masterclass aims to answer all the questions you have always wanted - and will be able - to ask, such as:

  • At which air-tightness levels is MVHR beneficial and why?
  • How do you write the specification for an efficient system?
  • What are typical running costs and capital costs?
  • What are maintenance and access requirements?
  • How is it controlled and how do occupants respond?
  • And many others...

This Masterclass will include a hands-on demonstration using a Paul MVHR unit, supplied by Paul Heat Recovery Scotland.

Delivered by

Alan Clarke, who is a leading energy consultant and building services engineer who has designed ventilation systems for a range of Passivhaus projects, seeing them through from concept design through to post occupancy evaluation.

Andrew Farr, who is the Green Building Store’s ventilation technical expert, and has commissioned most of the Passivhaus ventilation systems in the UK.  He will illustrate some of the principles discussed with an actual MVHR unit.


Who should attend?

Architects, engineers, planners, building control officers, energy managers, builders, housing associations, researchers and others who want to learn more on how to deliver real low energy buildings.

The Masterclass is aimed at those who have already designed a Passivhaus project OR completed the CEPH training course. 

If this is not the case, we recommend that you attend the morning introductory session before the Masterclass.
