Future of energy efficiency debate

Quanexattended the 23rd International Passivhaus Conference in China.

Taking place at the Gaobeidian Window City, Asia’s largest window industry exhibition centre, the event drew over 1,000‘thought-leaders’ from around the world to discuss the latest developments in energy-efficient construction.

Since it was established in the early 1990s, Passivhaus has gone on to become the world’s foremost voluntary standard for energy efficient buildings, and an initiative that Quanex has supported.

Managing director Chris Alderson said: “For over 30 years, we’ve been hugely passionate about energy efficiency as a business, and strong supporters of the Passivhaus standard.

“Until relatively recently, Passivhaus was niche – even today, there are only around 25,000 Passivhaus properties in the world, the vast majority of them in Germany, Austria and Scandinavia.

“But now, concerns about the environment are increasingly driving its adoption – and those concerns are only going to grow in the years ahead.

“Passivhaus is more relevant than it’s ever been, and in somewhere like China, it’s got enormous potential to do good.

“China is one of the world’s biggest and fastest-growing economies. Its rapid industrialisation has been one of the standout economic success stories of the last 50 years. But the environmental impact has been huge.

“Given that impact, and its vast population, what China does on sustainability matters, and for that reasonit’s been hugely gratifying to see it take action to radically improve the thermal efficiency of its buildings in recent years.

“China is making an immense effort to cut its carbon output, and initiatives like Passivhaus are a fantastic way to accelerate that effort, while helping 1.3 billion Chinese people live in more comfortable, energy efficient homes.”
