The Smartest Retrofit

We all know the acronym ESG. It’s been thrown around in boardrooms and lending documents for years. But as we move deeper into 2025, the conversation has shifted. Investors aren’t asking whether buildings should be “green.” They’re asking: where’s the proof?

And here’s the quiet truth: the proof doesn’t come from glossy sustainability brochures or a new coat of paint. It comes from data — the kind that tells you not just how your asset looks, but how it performs, and how people live inside it.

That’s why the most important retrofit of this decade isn’t about glass and steel, but about wiring your assets for insight.

Data as your Insurance Policy.

If you own or manage real estate, risk is your constant shadow. From damp and mould claims to overheating complaints, the liabilities are real and increasingly public. The UK Housing Ombudsman has already warned that damp and mould cases are a “major source of resident distress and litigation risk.”

Without hard data, problems go unseen until they hit the courts or the headlines. With data — room-level temperature and humidity monitoring, air quality tracking, energy performance insight — you have foresight. You can prove compliance, pre-empt complaints, and avoid spiralling legal and reputational costs.

In that sense, data isn’t just a sustainability tool. It’s an insurance policy.

Why Residents still Hold the Keys.

For Purpose-Built Student Accommodation (PBSA), the lesson is even sharper. Students are more discerning than ever: they compare Wi-Fi speeds, community vibe, wellbeing support, and building management responsiveness before they even glance at square footage.

Research from Knight Frank and UCAS shows a clear gap: 76% of PBSA residents report being satisfied, compared to just 70% in the private rented sector. That may not sound seismic — until you realise satisfaction is the single biggest predictor of renewals and recommendations. The difference between keeping a resident for another year and losing them to a cheaper private flat can be the difference between outperforming your pro forma and missing it.

Data closes that gap. It tells you what rooms are overheated in one corner of the building. It shows you which amenities actually get used. It measures how quickly maintenance tickets are resolved. It’s the difference between guessing what residents want and proving you’ve delivered it.

PropTech isn’t an Add-On, it’s the Foundation.

This is where PropTech solutions step in — platforms like Utopi, stitching together building performance data with resident engagement tools. Imagine a dashboard that shows, in real time, the health of your asset and the pulse of your community.

That’s more than convenience. It’s strategy. You can prioritise investment where the data shows the biggest risk or the biggest return. You can demonstrate to lenders not just that you’ve “gone green,” but that you’re continuously measuring and managing outcomes. You can create a living feedback loop with your residents, instead of relying on once-a-year surveys that arrive too late.

The Cultural Shift: Buildings that Listen.

At its core, this is a cultural shift in real estate. For decades, we’ve built assets that stand still. Now, we need assets that listen — to the environment, to the resident, and to the demands of regulators and financiers.

Retrofitting for data isn’t glamorous. You won’t cut a ribbon for a new sub-meter. But in ten years, when your assets are still commanding premium valuations, still qualifying for green finance, and still holding onto their residents, you’ll be glad you did.

Because retrofitting data isn’t just about being sustainable. It’s about being resilient.

In the winter of 2024, YourTRIBE kicked off a campaign in their newly retrofitted gas asset in South Bermondsey. With new Utopi Smart TRV’s installed, they wanted to see their gas consumption reduce significantly. Data, insights and asset performance optimisation were the key focus in this instance, and by enhancing insights and empowering YourTRIBE with remote controls through the retrofit project, it would help transform their heating emissions.

Our data strategy was to use Utopi Multisensor data to assess temperature distributions, we would then analyse this alongside other factors like occupation and external temperature to gauge impact. This way we would get a holistic view of the asset’s consumption:

• Multisensors: Acquired daily avg. bedroom temperatures.
• PIRs: Acquired occupancy for each bedroom.
• External temperature data was used to select comparison periods with a similar external climate.

And the control regimes we would implement via The Utopi Platform to reduce outliers and monitor progress would be:

• TRV temperature limited at maximum 22-24°C.
• TRV set point stepped down to 20°c after 4-5 hours and to 15°C after 24
