Solutions connecting the retrofit value chain

Tallarna addresses the issue of large-scale decarbonisation by connecting all parts of the retrofit value chain. Creating a holistic ecosystem, customers are empowered to identify, design, insure, fund, and contract projects in one place. The company specialises in the social housing sector but has wider applicability to commercial real estate and, soon, industrial sites.

Initially, minimal data input is required to understand buildings’ energy usage and create digital twins. These are then leveraged to generate decarbonisation pathways and business cases. Tallarna’s AI platform, KESTREL, analyses thousands of retrofit options to find the best fit for a given portfolio and to suggest financially viable projects. Each project’s capex requirements and payback time are specified to fit the user’s goals, as well as the forecasted carbon and energy reductions.

KESTREL then quantifies the risk of project underperformance, with generated metrics mapping to a Fortune 500, A-rated insurer’s underwriting criteria. This enables a project’s financial outcomes to be guaranteed, providing confidence to ESG funders.

Tallarna facilitates access to large-scale ESG finance, with customers able to enjoy zero/low capex solutions and off-balance sheet treatment. Retrofit projects pay for themselves through the realised energy savings in a pay-as-you-save model. Between 10-25% of the energy savings stay with buildings’ residents/occupiers, helping address fuel poverty.

Tallarna provides access to a trusted ecosystem of technology partners and contractors for projects, or customers can introduce their own parties if preferred. This ensures procurement is undertaken with the greatest confidence and work is performed to the highest standards.

Tallarna offers customers ‘decarbonisation-as-a-service’. This translates to a yearly license fee which encompasses the onboarding and hosting of buildings on KESTREL, scoping of retrofit projects, forecasting of energy savings, and the delivery of initial financing terms. This fee is based on the number of properties uploaded, allowing customers to pay according to their needs. Once customers are confident that there is a business case to retrofit their properties, Tallarna will carry out technical, financial, and insurance due diligence. This equates to a one-off fee.
