Revolutionising the approach to retrofit & building upgrades.

Retrofitting existing buildings is a complex challenge. Every building is unique, and each retrofit must respond to its specific materials, systems, and patterns of use.

To make informed decisions, we need to understand how the building truly performs today, not just its fabric and services, but also how size, orientation, and usage affect energy demand.

Too often, this process relies on assumptions, leading to poor outcomes and repeated mistakes.

Seven innovative organisations have come together to test scalable and accessible retrofit approaches in 14 non-domestic demonstrator sites across the UK, as part of a £2.4 million project funded by the Innovate UK Net Zero Heat Fund.

Alchemai addresses at scale the barriers which exist for non-domestic estate owners to decarbonise their buildings. By combining digital twin technology, building performance expertise, and immersive visual tools, we optimise decision making helping building owners make confident, data-led retrofit decisions—reducing risk, avoiding costly mistakes, and ensuring the right upgrades are delivered at the right time.

The benefits of data-driven retrofit decisions

Deeper building insights: Understand the genuine performance of fabric, systems and energy usage patterns.
Deeper building insights: Identify the most cost effective upgrades for improving comfort and reducing carbon emissions.
Reduced implementation risk: Test retrofit scenarios virtually before committing capital, avoiding costly mistakes.

Our solution enables you to visualise the impact of retrofit decisions before capital commitment, prioritise interventions based on cost, carbon and operational risk, and optimise investment across entire estates for maximum long-term value.
