Passivhaus Large & Complex Masterclass Tall Buildings

Deep dive into a high rise at our third webinar (of six) as we continue the 2024 Large and Complex Passivhaus Masterclass series. Learn about student accommodation reaching new heights in London with this captivating case study Urbanest Battersea Park. Currently underway, it is applying Passivhaus at a mammoth scale.

Delivering this complex project required considerable expertise from both a thermal envelope and mechanical systems perspective. This webinar will provide an expert overview of key Passivhaus elements of what is currently one of the largest projects in the UK.

Large buildings & ventilation 

With Sally Godber, WARM and Liam McDonagh-Greaves,WARM

Sarah LewisSally GodberLiam McDonagh-Greaves

Embark on a journey into the world of Large and Complex Passivhaus design with our experts, Sally Godber and Liam McDonagh-Greaves from WARM low-energy building consultants and Passivhaus certifiers. Sally will share essential dos and don'ts for successful large projects. Following this, Liam will guide you through the intricacies of ventilating large buildings, offering design tips and insights for incorporating these strategies into the Passive House Planning Package (PHPP). Join us for a dynamic session filled with practical wisdom and expert advice on navigating the complexities of designing and ventilating large and complex buildings in the realm of Passivhaus construction.

Air tightness & air testing of large multi-residential blocks

With Piers Sadler, Delta Q, Megan Ancliffe, Delta Q and Paul Jennings, Aldas

Sarah LewisPiers SadlerMegan AncliffePaul Jennings

Air tightness design and air testing of large multi-residential blocks presents a number of design and practical challenges, especially in locations where planning requirements require building emission rates to improve upon Part L, such as within the Greater London Authority region. Issues we will cover are: defining the thermal envelope, choosing compartments for pressure testing, co-pressurisation tests, air tightness requirements for individual dwellings, interim testing and final testing including tall buildings. If these aspects are not carefully planned out before construction, testing and air tightness costs can spiral.

CASE STUDY: Tall buildings - Urbanest Battersea Park project

With Dr Thomas Henriksen, Henriksen Studio and Tomás O’Leary, MosArt

Sarah LewisThomas HenriksonTomas O'Leary

An 850-unit Passivhaus student accommodation project in Battersea is making solid progress and is set for completion in early 2024. Topping out at 19 storeys and clad in colourful terracotta facades, the project will undoubtedly make a bold impression on the London sustainability skyline. Delivering this complex project required considerable expertise from both a thermal envelope and mechanical systems perspective. The unitized curtain walling strikes a balance between oft-opposing winter and summer energy demands and the building services specification optimises indoor air quality and reduced internal heat gains. The webinar will provide an expert overview of key Passivhaus elements of what is currently one of the largest projects in the UK.

Heat pumps for large and complex buildings

With Alan Clarke and Gwilym Still, Max Fordham LLP

Sarah LewisAlan ClarkeGwilym Still

Join Passivhaus consultants and MEP designers Alan Clarke and Gwilym Still for an insightful discussion on the pivotal role of heat pumps in large and complex Passivhaus projects. Dive deep into essential design considerations, drawing on real-world case studies and the lessons gleaned, so far, from practical experiences. Throughout this session, Alan and Gwilym will share their wealth of knowledge, offering design tips for effectively integrating heat pump solutions into the Passive House Planning Package (PHPP), providing you with practical takeaways for your own projects.

Thermal bridging – strategies and insights for large concrete frame buildings

With Piers Sadler, Delta Q, Megan Ancliffe, Delta Q and Will South, Etude

Sarah LewisPiers SadlerMegan AncliffeWill South

Thermal bridging contributes significant heat loss which results in uncertainty during the design development of concrete frame buildings.  At the same time thermal bridge modelling can become a high cost design activity, with frequent update requirements. We will explore strategies for risk mitigation at early stage design, share λ- and ψ-values we have calculated for different situations and present some general observations from our 2D and 3D thermal bridge modelling. We will also cover technical design, construction quality and provide a certifier’s perspective.
