Shaping Tomorrow's Built Environment Today
January 9, 2025
Microsoft has been investing billions to enhance its AI infrastructure and broaden its data center network. Analysts expect Microsoft's fiscal 2025 capital expenditure (including capital leases) to be $84.24 billion. The company's capital expenditure in the first quarter of fiscal 2025 rose 5.3% to $20 billion. Read more
Experts have been hired to help the UK government fight misinformation about heat pumps and encourage adoption of the technology. A target of installing 600,000 a year by 2028 is part of a drive to achieve Britain’s commitment to reach net zero by 2050. However, misinformation shared in the media and by “other stakeholders” is impeding uptake, according to a £100,000 government contract awarded to the Behavioural Insights Team, which specializes in ideas to “nudge” the public into taking different actions. Read more

A reactor that splits water to make hydrogen using sunlight and photocatalysts, without conversion to electricity in between, has operated successfully for three years. Researchers at Shinshu University in Japan built a 100 m2 (1,076 ft2) prototype reactor using sheets of the photocatalyst SrTiO3: Al.  Read more
A university is probing whether retro-fitting homes to make them more energy efficient may reduce the amount of fresh air being circulated indoors, putting people with existing health issues at risk. The three-year study, a collaboration between Newcastle University, the city’s council and the London School of Hygiene and Tropical Medicine, has already collected data on 30 single-story terraced homes in the city that are due to have energy efficiency improvements implemented. Read more

Fueled by the rapid rise in artificial intelligence, data centers could triple their energy use by 2028, accounting for as much as 12% of the country’s electricity consumption, according to a new report backed by the U.S. Department of Energy. The findings from the Lawrence Berkeley National Laboratory add to the flurry of warnings about the toll that data centers could take on the nation’s electric grid. But administration officials say they’re not concerned about the grid’s ability to handle the needs of the growing industry. Read more
