Passivhaus centre stage at the 2018 AECB Convention

AECB Convention 2018 at Garway Village Hall

This month (September 2018) saw the annual AECB convention take place in a remarkable Passivhaus venue, Garway Village Hall.

Herefordshire, a largely rural county of winding lanes and beautiful views, is an unlikely hotbed of Passivhaus activity, so convention delegates were afforded the opportunity to experience several local Passivhaus projects firsthand. Site visits were arranged to the RIBA award-winning - and UK Passivhaus Awards Finalist - Hope View HouseFishleys Passivhaus, Ty Pren, and Silver Birches.

Back at the convention venue, keynote speaker by Dr Steve Fawkes, an energy efficiency expert, introduced new ways to encourage funding in energy-efficiency from an investor’s point of view – sparking interesting ideas for future Passivhaus & low carbon developments. Mark Barry, a director of PHT Patron member Architype, presented an overview of the practice’s work across Herefordshire (which is their home base) from small to large. Small one-off projects like Fishleys, Clehonger Passivhaus or Hennerwood Farm can often be a test-bed for innovative techniques, serving a prototyping function for larger projects. And at the large end of the scale, Architype’s portfolio includes the unique HARC, the Herefordshire Archive and Records Centre, on which Mark was the lead architect.

Also in the county, Old Holloway, the self-built home of Architype architect Juraj Mikurcik - and another UK Passivhaus Awards finalist this year - was highlighted by AECB CEO Andy Simmonds as an exemplar of the kind of radical simplicity approach that can deliver a comfortable and healthy sufficiency, and that could be held up as an important design principle for a sustainable built environment.


Nick Grant and Alan ClarkeTalking of radical simplicity, other sessions included a presentation by Nick Grant and Alan Clarke, two invaluable members of the Passivhaus Trust Technical Steering Group, who cast an eye back over 25 years of low energy building experience. The talk ranged from their earliest ventures into sustainable building, incorporating several principles of Passivhaus even before the Standard had reached the UK, to more current analyses of the impact of different fuel choices, and PHI’s work anticipating the fully decarbonised grid of the future with their recently introduced PER concept.

Another useful learning opportunity, this time for PHPP aficionados, came courtesy of Tim Martel of Optimal Retrofit, the creator of PHRibbon, the very useful PHPP add-on. His workshop introduced and demonstrated the tool - find out more from his newly released demo video.
