Understanding The Problem

The Thermal Performance Gap — where design intent meets operational reality.

Low-carbon thermal systems are increasingly deployed across housing and public estates. Real-world thermal outcomes are not always continuously verified. This is the gap FutureTherma was built to close.

The Hidden Gap

Designed to perform. Not always verified to perform.

Building programmes rely heavily on design-stage assumptions — modelled performance and specified outputs used to justify investment and communicate outcomes to occupants and stakeholders.

Between design intent and operational reality, a gap frequently exists. Systems operate under variable conditions, occupant behaviour, grid pressures and seasonal loading that design models do not fully anticipate.

Without continuous operational verification, that gap remains invisible — until it becomes a complaint, a cost, or a compliance question.

The Shift

"The next challenge in Net Zero delivery is not installation alone. It is performance assurance."

Where It Shows Up

Operational failure modes.

Thermal Imbalance

Rooms heat unevenly — some zones over-perform, others remain persistently cold.

Fuel Poverty Risk

Underperforming systems can drive up energy consumption as occupants compensate for inadequate warmth.

Mould and Condensation Risk

Cold surfaces and poor thermal regulation create conditions that can accelerate mould growth.

Operational Inefficiency

Systems work harder than designed, and energy waste accumulates invisibly without detection infrastructure.

Limited Operational Visibility

Without structured evidence, demonstrating performance to funders or stakeholders relies more on assumption than data.

The Compounding Effect

Where unverified performance compounds risk.

When thermal performance goes unverified, consequences can compound across three interconnected dimensions.

Occupant impact

Cold homes, uneven temperatures and rising energy costs can disproportionately affect the most vulnerable occupants.

Asset impact

Retrofit and heating investments can underperform, with portfolio-level inefficiency compounding without visibility infrastructure.

Compliance impact

Regulatory frameworks increasingly ask for operational evidence, not only design-stage assumptions.

Regulatory Landscape

The evidence expectation is growing.

Several UK regulatory and funding frameworks are placing increasing emphasis on operational evidence of thermal and energy performance, alongside design-stage compliance. FutureTherma does not guarantee compliance with any of these frameworks, and structured evidence is not a substitute for statutory assessment or professional judgement — but it is designed to give operators a consistent evidence base to bring to these conversations.

SHNZS

Scottish Housing Net Zero Standard — sets expectations for evidence of Net Zero performance across social housing stock.

PAS 2035

Retrofit assessment framework — principles around ongoing verification that retrofit interventions deliver intended outcomes in operation.

SHDF

Social Housing Decarbonisation Fund — funders increasingly expect evidence that funded interventions deliver measured outcomes.

Awaab's Law

Thermal risk and mould visibility — obligations around demonstrating awareness and management of conditions that create thermal risk.

The FutureTherma Response

The challenge is no longer installation alone. It is performance assurance.

FutureTherma addresses the Thermal Performance Gap with a deterministic infrastructure layer that continuously measures, determines, detects, corrects and evidences thermal performance.
