London’s Heatwave: The red hot case for sustainable fit out
Industry Has Been Saying This for 30 Years.
More recently, young advocates such as Greta Thunberg have been clear about where we were headed. Not alarmist – clear. And weeks like this one we’ve been through are exactly the case study she, and countless scientists, designers, and sustainability professionals before and after her, have been warning about for decades. Except now, it’s not a warning. It’s the news.
Schools closed because it was too dangerous for children to travel or try and learn in overheated classrooms. Offices became greenhouses – all that floor-to-ceiling glass doing its job beautifully for natural light and external views until temperatures soared, at which point it became a liability. Air conditioning units run flat out, and electricity bills reflect this. Trains and commercial events are cancelled. The infrastructure and built environment we built for a different climate is simply not fit for this one or the one we’re heading towards.
At SKArating, we have been making this argument since our inception. Sustainable design is not a preference – it is engineering for reality. And weeks like this make it impossible to argue otherwise.
The Cost of Getting It Wrong
The irony of weeks such as in June 2026 is not lost on us. Buildings designed to project modernity – maximised glazing, open atria, south-facing facades with no shading or thermal comfort strategy – became the very embodiment of what sustainable design has long warned against. Solar gain unchecked. No passive cooling. No biophilic buffer. The result: indoor temperatures that make working dangerous, not merely uncomfortable, and energy bills that reflect the emergency mechanical cooling required to compensate.
These are not freak occurrences. They are design failures that were and still are predictable – and preventable.
The Triple Bottom Line
What distinguishes the SKArating methodology is its refusal to treat sustainability as a single-axis problem. The triple bottom line – people, planet, and profit – is a design framework that ensures every decision in an interior fit-out or refurbishment is evaluated across three interconnected lenses.
Planet. Reducing embodied carbon, maximising resource efficiency, selecting materials with verifiable provenance, and designing for circularity and longevity – not just for certification.
People. Thermal comfort, air quality, daylighting, acoustic wellbeing, and biophilic connection. Emotional health and comfort. A building that makes its occupants unsafe has failed, regardless of its energy rating.
Profit. Lower operational costs, reduced energy cost fluctuation exposure, higher occupant productivity, greater asset resilience, brand and image value and regulatory future-proofing. Sustainable design is the sound investment – and June 2026 weather patterns proved it in real time, on electricity bills and commercial or social activities across the country.
The SKArating framework assesses interior fit-outs and refurbishments across 80+ criteria to create drive and accountability at every stage of design, construction and operation. Not as a burden – as a discipline that makes better buildings.
