The Oxford roof that led the way in tackling climate change
Thirty years ago, a quiet suburban street barely noticed the start of a revolution being built on its doorstep.A house constructed in 1995 was the first in Britain to incorporate a solar roof and would set the agenda for domestic renewable energy.Earlier this month, Energy Secretary Ed Miliband said the "vast majority" of new build homes in England will be required to have solar panels.Key pioneers and figures from Britain's solar energy community have gathered to mark the 30th anniversary of the Oxford Ecohouse that led the way.
Leading the way doesn't come cheap.The first ever solar roof cost Prof Sue Roaf £28,000 to build. With no planning regulations at the time that addressed such a construction, the build proved particularly challenging.She told the BBC: "To build this house, I had so much help from the industry because they bought into the vision."The idea that with the ordinary family home you could have a decent, ordinary life and have very little footprint on the planet."Despite the challenges the build was a success. The six-bedroom home produces 130kg CO2 a year per sqm. A comparable UK house produces 5,000kg CO2 a year per sqm."We were seen as living the ordinary life but just slightly differently," she said. "It was the solar life."
The award-winning house gained international attention and inspired a new wave of climate architects."Sue was this slightly legendary figure," recalls architect and TV presenter Charlie Luxton, who was studying at the time.The house brought photovoltaics (PV) - the process of converting light into electricity using semiconducting materials - and "low energy architecture to a very domestic setting", he said."The house could fit in on any street. I think that's what is so amazing about this project - that it could be everywhere, it should be everywhere."Every house built since then should have looked like this or at least had this level of thinking around PV and low energy and reducing the impact on planet and climate."
Despite the revolutionary house being built in 1995 the idea of solar on domestic properties took a while to catch on."It wasn't until 2010 that the panels really became affordable," said Prof Roaf.Fast forward to 2025 and Energy Secretary Ed Miliband has said builders will be required to fit solar panels to the "vast majority" of new homes in England under changes to be published this year.The rules will be included in the Future Homes Standard, which will detail a wider plan for improving energy efficiency and reducing carbon emissions.With a government target of 1.5 million new homes to be built by 2029, insisting new homes have solar panels could make a significant contribution.But architects like Alex Michaelis are worried such policies will not be permanent.He said: "The fear always with these things is that in five years' time, with a change in government, they scrap it."This is one of my big things, that a lot of these things should not be party-politically based but there should be another body that says 'right, we set this in stone for 20 years'."
One lasting legacy of the Ecohouse was the effect it would have on one of Prof Roaf's sons.Richard Roaf appeared as a schoolboy on Blue Peter when the programme featured the home. He gained the nickname "solar panel boy" but says that didn't put him off."I think my mum predicted it a bit before a few other people but I was actually inspired to get really involved in climate change campaigning," he said."I think both the solar house and being on Blue Peter, despite the nickname, did inspire me to go off in that direction."Standing on the balcony of the home she built, Prof Roaf reflected on what has been achieved as guests gathered for the anniversary party."I'm proud of what we built together because it wasn't me who bought the house, it was the team," she said. "And lots of them have come to celebrate."As for the running costs for the house?"Last month, for gas and electric without VAT and without standing charges, it was £7.56. I rest my case, your honour."

Volunteers rehome 1,500 BBC Gardeners' World plants in Leicester
Staff and students at the University of Leicester have installed 1,500 plants recently displayed by BBC Gardeners' World presenter Nick plants, worth in the region of £15,000 to £20,000, were used by Bailey during BBC Gardeners' World Live, which ran from 12 to 15 June at the National Exhibition Centre (NEC) in 20 volunteers spent three days in the heat - finishing on Friday - moving soil and replanting at the university's 16-acre botanic garden, of which Bailey is the said the work was "challenging" but that the additions to the garden were "superb". Bailey, who was appointed director of the botanic garden in May 2024, said he saw the opportunity to use his resources and combine his roles to improve the area for visitors."The BBC asked me to create the headline show garden for Gardeners' World Live," he said."Usually at the end of a show garden process there is a lot to dispose of."Bailey and the team of volunteers helped remove the weeds and soil from the area, before planting around the water garden area of the site in soaring temperatures."It's been challenging and it's the hottest week that we've had all year," he said."The good thing about show gardens is that all the plants are planted in their pots, after the show they can be transported straight here."What's great about the garden now is that there are so many different species, which are superb for different pollinators so it celebrates the biodiversity of the garden as well." One of the volunteers was Dr Katherine Clark, a senior lecturer of biological sciences at the university."I'm a keen gardener and constantly looking to learn more about plants and to have somebody like Nick Bailey here to direct us is brilliant and what this garden needs," the 53-year-old said. "It's suddenly turned from bare soil into this beautiful garden again." Fellow volunteer and computer science student, Vatsal Chaudhari, said it was "pretty satisfying" watching the garden change."It's been hard but we've had fresh hands helping every day, we were getting through 500 plants a day at around 50 plants per person," the 23-year-old said."The other volunteers have done an amazing job, I'd love to see more students get involved in keeping the garden looking like this, hopefully this will encourage more to join in next time we're planting."

Noise pollution harms health of millions across Europe, report finds
More than 110 million people across Europe suffer high levels of health-damaging noise pollution, according to a report. The resulting physiological stress and sleep disturbance leads to 66,000 early deaths a year and many cases of heart disease, diabetes and depression. The report, from the European Environment Agency (EEA), focuses on noise from cars, trains and aeroplanes and found that 20% of the population of the European Economic Area (EEA) were affected. Separate research, using a slightly lower threshold for dangerous noise pollution, found that 40% of the UK population were exposed to harmful transport noise. Seventeen million people endure particularly high noise pollution – 'long-term, high-annoyance' – and almost 5 million suffer 'severe' sleep disturbance. Fifteen million children live in areas of harmful noise. The harm to health from noise is greater than that from higher-profile risks including secondhand tobacco smoke or lead exposure, and incurs an economic cost of almost €100bn (£86bn) a year, the analysis found. The damage to health is likely to be an underestimate, the researchers said. Using the World Health Organization's stricter threshold for risky noise pollution gives an estimate of 150 million people across Europe exposed. The EU's target to cut the number of people chronically disturbed by transport noise by 30% by 2030 will not be met without further action, the researchers said. 'Noise pollution impacts our health by keeping our bodies in a constant state of fight or flight, even if we don't consciously realise it,' said Dr Eulalia Peris at the EEA. 'This can lead to harmful physiological responses such as inflammation and oxidative stress, and over time, this increases the risk of various health issues, including heart disease, diabetes, stroke, obesity, cognitive impairment in children and mental health problems.' 'Noise pollution is not only an annoyance,' added Peris, who has been affected herself. 'My God, yes. I'm very aware of the impacts of noise pollution, and I'm very sensitive to it. It limits your life.' The report is based on data reported by EEA countries on transport noise, which is the most widespread and significant type of noise pollution. Other kinds, such as loud neighbours and music from bars, are also likely to damage health but are difficult to measure because of their intermittency. The report found 92 million people across Europe were harmed by road transport noise, 18 million by railway noise and 2.6 million by aircraft noise. Published research on the health impact of noise pollution was used to estimate an annual toll of 66,000 premature deaths, 50,000 cases of cardiovascular diseases and 22,000 cases of type 2 diabetes. The number of people in Europe affected by noise fell by only 3% between 2017 and 2022, but the researchers said numerous measures could be taken. Cutting speed limits for vehicles in urban areas and boosting the use of low-noise tyres would cut road traffic noise, they said, as would promoting public transport, walking and cycling. The increasing number of electric cars will reduce noise less than might be expected, the researchers said, because the key source of noise at lower speeds is from the contact between the tyres and the road, not the engine. Traffic noise is also dominated by a small number of very loud vehicles. Sign up to Down to Earth The planet's most important stories. Get all the week's environment news - the good, the bad and the essential after newsletter promotion Railway noise could be cut by better maintenance of trains and track, and aircraft noise could be reduced by optimising landing and takeoff patterns and encouraging the introduction of quieter planes. 'Noise pollution is often overlooked, considered just an annoyance of everyday life,' said the EEA's executive director, Leena Ylä-Mononen. One reason for this is that transport noise pollution is chronic, unlike air pollution which has peaks that lead to health alerts and raise awareness. 'However, long-term impacts of noise on our health and environment are widespread and significant,' she said. 'Children are also particularly vulnerable to the effects of noise, and it's a problem all countries need to address urgently.'
