MVHR - Making ventilation systems work

Date: 19th February 2013 Time: 14:00-17:00
Location: Jevons room, first floor of UCL Energy Institute, Central House, 14 Upper Woburn Place, London WC1H 0NN Cost: PHT Members £95+VAT; non-members £150 +VAT

When designing to 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?
  • What are other ventilation options? Why not just open windows?
  • What are typical running costs and capital costs?
  • How noisy is it? What about air-quality?
  • What are maintenance and access requirements?
  • How much space does it take up and what are aesthetic considerations?
  • Where should vent inlets and outlets be positioned? How do you write the specification for an efficient system?
  • What are the requirements for Passivhaus certification?
  • What are boost-functions, and summer-by-passes? 
  • How is it controlled and how do occupants respond?

The workshop will be delivered by:

Alan Clarke, who is an 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
