2024 Large and Complex Passivhaus Masterclass

2022 Large and Complex Passivhaus Masterclass

Larger UK Passivhaus projects are emerging with increasing scales that bring new challenges. Continuing the success of our 2022 series, our online Passivhaus Large & Complex Masterclass series covers topics in demand! How do you airtest a high-rise block? What MVHR systems work best for 100+ home developments or bespoke non-domestic settings?

We have planned new in-depth case studies, as well as topic-focused sessions. Learn from expert practitioners working in the field. Enrich your practical and technical knowledge for your large-scale Passivhaus projects.

Ventilation 2  1.5hr 5 Topics | 1 Quiz Buy to unlock

Kick off the 2024 series with insights into design challenges for super-sized Passivhaus from PHT Patron and WARM experts. Learn essential dos and don’ts for large projects, including ventilating big buildings and incorporating strategies into the Passivhaus Planning Package (PHPP). Discover whether duct lengths matter and the pros and cons of centralised versus decentralised systems. Join a live session with Sally Godber and Liam McDonagh-Greaves of WARM for expert advice on designing and ventilating large Passivhaus buildings.

Airtightness & testing for multi-residential blocks 2  1.5hr 6 Topics | 1 Quiz Buy to unlock

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.

Learning outcomes
  1. Recognise options for final air pressure testing in Passivhaus multi-residential buildings.
  2. Assess implications of individual dwelling airtightness for surface area treatment in large Passivhaus blocks.
  3. Identify building compartments in multi-residency blocks.
  4. Understand the options for testing building compartments in Passivhaus buildings.
  5. Assess the suitability of co-pressurisation testing in multi-residency buildings.
  6. Plan interim testing for multi-residential concrete frame Passivhaus buildings effectively.

Heat pumps 2  1.5hr 5 Topics | 1 Quiz Buy to unlock

Join Passivhaus consultants and MEP designers Alan Clarke and Gwilym Still, Max Fordham LLP 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 a range of building typologies from retrofits and schools to multi-residential and student accommodation blocks, providing you with practical takeaways for your own projects.

First delivered on: 24 April 2024
Speakers

Alan Clarke
Gwilym Still

Learning outcomes
  1. Understand the Efficiency of Heat Pumps: Explain how heat pumps provide the most efficient means of decarbonising heating through electrification.
  2. Recognise the Impact of Heating System Temperature: Analyse the critical dependence of heat pump performance on heating system temperature and how this fundamentally differs from fossil fuel heating systems.
  3. Design for Low Flow Temperature: Identify the need for designing heating systems with low flow temperatures to optimize heat pump efficiency, including the new approaches required for emitter design and the separation of domestic hot water production.
  4. Implement a Combined Approach for Heat Pump Installation: Assess the requirements for replacing fossil boilers with heat pumps, including evaluating building fabric improvements and reassessing emitter capacity at low flow temperatures to determine necessary upgrades.

Thermal Bridging 2  1.5hr 6 Topics | 1 Quiz Buy to unlock

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.

First delivered on: 19 June 2024
Speakers

Piers Sadler
Megan Ancliffe
Will South

Learning outcomes
  1. Make decisions about thermal bridge modelling to effectively minimise both risk and expenditure
  2. Understand the outputs from a thermal bridge model
  3. Anticipate potential locations for thermal bridging in concrete frame construction
  4. Evaluate the relative importance of thermal bridges in a project
  5. Understand why thermal bridges are a factor in large buildings 
  6. Plan a timeline for thermal bridge calculations aligned with RIBA Stages
  7. Locate further resources to help in making thermal bridge calculations
  8. Understand how to apply your learning on a project via real world detail examples
