Green Urbanist - Sustainable Placemaking, Planning and Urban Design
100+ episodes exploring climate action in cities and neighbourhoods.
This show provides actionable advice and case studies on:
- Sustainable urban design and placemaking principles.
- How to design cities and neighbourhoods for biodiversity net gain and wildlife.
- Climate adaptation: How to build resilience to climate change in cities.
- Net zero carbon masterplanning and architecture.
- Circular economy: How to minimise waste and emissions in new development.
- Transport: How to transition cities away to sustainable and active travel.
- Regenerative Design: Delivering positive benefits for the environment and communities.
Who is it for? Urban designers, planners, developers, architects, landscape architects, urban ecologists, engineers, transport professionals and urban citizens.
The Green Urbanist podcast is hosted by Ross O'Ceallaigh, an urban designer and sustainable placemaking consultant.

#21: Jake Attwood-Harris (Hawkins\Brown) - Whole Life Carbon, Zero Carbon Architecture and Retrofitting for Sustainability
Jake is Sustainable Design Advisor at Hawkins\Brown where he led the development of the free open-source Hawkins Brown Emissions Reduction Tool, also referred to as H\B:ERT, which is a whole life carbon calculation tool. Jake works across all project stages; developing and reviewing key sustainability strategies and targets. His work is at the boundary between architecture and engineering; working with passive design techniques to create comfort in buildings before using modern technology where it counts.
In the episode Jake and I discuss:
- The practicalities of achieving net zero carbon by 2050
- Taking an evidence based approach to designing zero carbon buildings
- The challenges of retrofitting existing buildings for energy efficiency, and
- Why it is essential that Architects are trained and educated in sustainable design principles.
Heads up on some terminology we use:
Whole Life Carbon: an approach to designing buildings that takes into account emissions from the building's entire life, including construction and operation. So, it's the most accurate way of assessing actually how many emissions are associated with a building.
We also talk about Hawkins Browns' Revit Plugin for assessing carbon emissions. If you don't know, Revit is basically a 3d modelling software used by architects and engineers, which has a database built in so you can store data in the model.
Scope 1, Scope 2 and Scope 3 emissions: Scope 1 relates to emissions directly from burning fossil fuels. Scope 2 relates to indirect emissions from energy use. And Scope 3 relates to embodied emissions, in this case from building materials.
