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.


Due to client sensitivity, this session is not available as a recording.

CASE STUDY: Tall buildings - Urbanest Battersea Park project

With Edwin Stokes, Henriksen Studio and Tomás O’Leary, MosArt

Sarah LewisEdwin StokesTomas 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.

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.
