Hot on the heels of my blog post earlier this week comes news of the greenest building in the world!
I had a meeting with Juwi – a sustainable energy company in the week and they were keen to tell us about their ‘life choices’. The spiel goes, “Our headquarters in Wörrstadt are the world’s most energy efficient building in the world, which produces more energy than is used.”.
So, the World’s most energy efficient building. You can download their data sheet here. It makes for interesting reading.
On the face of it, it’s pretty ‘green’. Solar panels, wind turbines, natural ventilation -lots of natural light and all of the other features we have become used to.
They are a hugely successful company – 1,400 employees and €800m turnover. They do live a green way of life.
But is their claim about being the greenest building in the world right? Well, the answer is that I don’t know. I can’t get any information. It seems they produce more energy than they need. But I can’t work out how much. Nor can I find any information on what certification has been used for the building. In Germany I had thought the body responsible was the German Sustainable Building Council – they have a website here. It even has a list of certified buildings here.
This is not a blog post criticising Juwi – far from it, I think their building looks brilliant. And it clearly is ‘dark’ green! It has all of the features we have become used to – and they need to be congratulated on their work.
But, I think this reinforces my earlier blog post. we need some consistency in how we measure buildings. And be clear about what we are measuring. We also need to be careful if we make bold statements – like being the greenest, bluest, yellow-ist etc.
