Checking the Pulse: Passivhaus in Practice - Online
In the first decade of the 21st century, the passivhaus standards were often considered ‘nice to have but too expensive and difficult to build’ and it was not until 2009 that the first certified passivhaus building in the UK – a detached house in rural Wales – was completed.
Nine years later the number of certified passivhaus buildings including EnerPHit (passivhaus for existing buildings) exceeded 1000 and the building types now include houses, schools, offices and even a passivhaus church.
About the event
This informative session will chart the rapid acceptance of passivhaus in the UK and Ireland as an achievable, affordable standard that can make a huge contribution to reducing the impact buildings have on our environment.
After an opening address from Jon Bootland, CEO of the Passivhaus Trust, we’ll hear from Sally Godber, building services engineer and co-founder of WARM (energy consultancy and passivhaus design). Sally will look back at where passivhaus was at the beginning of this century, where we are now and what the future looks like for this important building standard. Sally will also touch on how costs for building to passivhaus standard have decreased as our understanding increases.
Hannah Jones and Paul Smith of Greengauge engineers will explain the implications that Covid-19 has had on ventilation systems, talk about the potential for aerosol transmission in poorly ventilated indoor spaces and the role of MVHR in reducing this risk.
They will then present some key mitigation measures we have available to improve the efficiencies of indoor ventilation to reduce the risk of spreading SARS-CoV-2 through airborne transmission and finish with the implications this has on MVHR design, unit selection, ventilation rates, power consumption and management control systems.
Following Greengauge’s talk, we will present four ’warts-and-all’ case studies to illustrate how the standard is applied across different building types, where the design team - a combination of the architect, client, contractor and building services engineer - encountered challenges and how they overcame them.

Setting the scene, how far we have come, where we are going, passivhaus costs.
10.45 Passivhaus and Covid-19: ventilation issues - Hannah Jones and Paul Smith, Greengauge engineers
Setting the scene, how far we have come, where we are going, passivhaus costs.
10.00 Case Study 1: Single dwelling – Niall Crosson, Group technical manager, Ecological Building Systems, co-presenting with his architect Niall Smith, Niall Smith Architects.
After nearly 20 years training, writing articles, and providing guidance to many low energy projects in Ireland and the UK, it was finally Niall’s turn to build his family home. Been in the fortunate position of having inherited a picturesque site in the north east of Ireland, the time was right for Niall and his family to finally build their own Passivhaus insulated with natural insulation materials. Building to the Passivhaus standard and using natural insulation was always an obvious choice for Niall, having trained so many in this field over the last 2 decades and having experienced its benefits through countless site visits, training and both national and international conferences. Niall will share his experiences, challenges and lessons learnt over the course of his project
10.30 Case Study 2: Social housing - Associate Director James Turner will discuss how Mikhail Riches delivered the RIBA Stirling Prize 2019 winner Goldsmith Street in Norwich, the UK’s largest 100% Passivhaus, 100% Social housing project at scale affordably.
11.00 Break and Networking
11.25 Case Study 3: School - Architype associate Christian Dimbleby, a dual-qualified Architect and CIBSE Chartered Engineer.
Christian will talk about the first Passivhaus secondary school in the UK: Harris Academy Sutton. He will explore how Architype took lessons learnt from more than 10 years of Passivhaus projects to push the boundaries of scale and design in this award-winning sustainable school in Sutton. His presentation will cover working with contractor and client to upskill and educate, simplifying complexity and detailing for contractors, as well as favouring low-carbon and biophilic materials to create a truly exemplar green space – a blueprint for a new generation of schools.
11.55 Case Study 4: EnerPHit (passivhaus retrofit standard) – Paul McNally, architect and Director, The PassivHaus Architecture Company co-presents with contractor Finbarr Favley two EnerPHit projects in Ireland. Paul and Finbarr will illustrate their experience in modernising existing buildings to certified PassivHaus and Enerphit standard, looking at a detached masonry two storey family home in Cork, and an urban mid-terrace three-storey pharmacy in Tipperary
