We are a built environment specialist consultancy. Our aim is to reduce the environmental impact of buildings through a reduce-first consulting approach. Our services include advising on 1.5°C-aligned pathways for portfolios, passive design measures, performance-based certifications, and guiding sustainable masterplan developments. We are experts in building physics, thermal comfort, dynamic modelling, energy policy, and academic research. This enables us to provide holistic advice to clients — ensuring that built assets perform within the bounds of a 1.5°C climate change trajectory whilst achieving stringent indoor comfort criteria in a cost-effective manner.

We help align your portfolio with the 1.5°C climate change trajectory.
More real estate investment trusts are requiring their funded assets to meet various climate change targets — be it SBTi, CRREM, or the EU Taxonomy. Whether you have a portfolio of existing buildings or are considering funding a new development scheme, Joule can help you achieve these requirements. Read more →
The energy hierarchy: A reduce-first consulting approach.
Given the limited supply of zero-carbon energy available for each of the economy’s sectors, we firmly believe that an immense reduction in energy demand is needed to decarbonise the buildings sector. In this blog, Bashar Al Shawa explains the science behind this limit and how this shapes Joule’s approach to consulting. Read more →

Designing for a warmer climate: Back to basics?
The science is clear — the climate is warming, and architects and engineers need to future-proof the buildings they design. But how can we achieve that whilst avoiding the vicious cycle of warmer climate → more air conditioners → warmer climate? In his Fast Company article, Bashar Al Shawa talks about how reviving traditional passive techniques could mitigate the effects of climate change without making the planet pay. Read more →

How energy-efficient should buildings be under the Paris Agreement?
The industry has long focused on reducing buildings' energy demand through energy efficiency measures. But given the sector’s enormous projected growth until 2050, just how energy-efficient should buildings be under the Paris Agreement? In his latest research paper published in the Energy Reports journal, Bashar Al Shawa shows that extremely stringent energy efficiency levels — far greater than we've ever achieved — are needed.
