Why Lüften brings relief in the midst of winter

Keeping warm and staying healthy: why we need a winter ventilation rethink The UK is in the grip of freezing temperatures, with overnight lows falling well below zero. Windows are shut tight, draughts are blocked and everyone is trying to keep the heat in. It's an understandable instinct as heating costs are high, and homes lose warmth quickly. But, while closing everything up feels sensible, it brings a dangerous consequence: damp, condensation and black mould. As we heat our homes but reduce ventilation, indoor air becomes humid and stale. Hidden moisture settles on cold walls and windows, and, in the…

How on-demand transport will support an ageing UK population

Designing cities for the future: the changing cost of independence The way we move around our towns and cities is going to change dramatically over the next 20-25 years. Ageing populations, technology shifts, climate pressures and rising costs will reshape not only how we travel, but how our neighbourhoods function. For millions of people, mobility is more than a practical question - it is the foundation of independence, dignity and community life. For years, the sustainability debate has been dominated by discussions about vehicles: EVs, emissions standards, charging infrastructure, and the decline of the combustion engine. Yet the real transformation…

Retrofit and decarbonisation: it’s time to rethink the route to scale

Retrofit with purpose: rethinking decarbonisation and design Across the UK, the call for mass retrofit grows louder by the month. Buildings account for around 40 per cent of our carbon emissions, and if we are serious about meeting net zero targets, large-scale retrofit is non-negotiable. Yet despite the ambition, the path we are currently paving could make true scale impossible. From May 29, 2025, new rules in England require all new Air Source Heat Pump (ASHP) installations to comply with the MCS 020a standard, but the new rules will not come into effect until May 29, 2026. From this date, all air source…

On the brink: why climate resilience can’t wait

The UK's weather is no longer just 'unpredictable' The UK's relationship with weather has long been one of mild fascination, but the days of gentle unpredictability are fading fast. We are now firmly in the age of climate disruption - and it's getting worse. From overheating cities to flash floods, droughts, wildfires, and infrastructure failures, the UK is no longer insulated from extreme weather. These events aren't 'one-off's' either - they're part of a volatile new normal. What we are seeing are climate 'whips' (hydroclimate whiplash) - sudden swings between extremes, such as torrential downpours following long dry spells, or…

The solar tipping point: new-build homes to get mandatory solar panels by 2027

A landmark policy shift The sun is finally rising on a more sustainable housing future in England. The UK government has announced that by 2027, virtually all new homes in England will be legally required to have solar panels installed during construction. This isn't just a nod to greener ambitions - it's a practical, cost-saving, and long-overdue change that could redefine our national relationship with energy. For decades, the conversation around decarbonising the housing stock has been weighted heavily toward retrofitting old buildings. But this policy, which mandates solar photovoltaic (PV) systems for new builds, shifts the focus to future-proofing…

Finland ahead of schedule on coal phase out

Finnish company P2X Solutions' commercial green hydrogen production at its facility  'Green power' in Finland has more than doubled since 2020 The recent closure of a coal power plant in Finland brought the country to the brink of a full coal phase-out - four years ahead of schedule. Power utility company Helen officially decommissioned its Salmisaari plant in Helsinki on April 1st, dropping coal to a less than 1 per cent share of the country's energy mix. Alongside reducing emissions and increasing energy independence, it says the switch is also helping it to cut customers' electricity bills. "We have been…

£180m solar investment for school and hospitals

Massive solar investment Hundreds of schools and hospitals across the UK are set to receive £180 million for solar panels from the government's new state-owned energy company. The first major investment from Great British Energy was recently announced as part of government efforts to reduce the country's planet-warming emissions. The move was welcomed by the school leader's union and NHS providers who said it would also help to manage the "enormous financial pressure" of energy bills. The government also hopes that the project, to provide solar panels for 200 schools and 200 hospitals, will reduce the use of fossil fuels…

2024 was a chaotic weather year

The effects of climate change are becoming more evident 2024 was a record-breaking year for extreme weather in the UK. Storms and floods caused an unprecedented level of damage to homes and businesses, leaving many homeowners facing costly repairs and insurance claims. Heavy rainfall, high winds, and flooding were more frequent and severe. With climate risks intensifying, homeowners can no longer afford to be reactive. Instead, proactive measures like retrofitting offer a long-term solution to protect properties against extreme weather. Retrofitting homes with better insulation, flood resistance, and storm-proof features is not just about avoiding damage - it is about…
