When you are thinking of sustainable houses and offices, you can imagine solar panels on the rooftop, double glazing windows or smart reuse of rainwater. For a house owner these choices are relatively easy to make. But what if you’re not an owner but a tenant? The office of Greenpeace Energy & Greenpeace Germany in HafenCity-Hamburg shows that being a tenant doesn’t have to stop you from making sustainable improvements to your office or house.
Obviously, making a difference is easier for an international and well-organized NGO like Greenpeace. But hopefully this case inspires you to get in touch with your landlord to explore the possibilities for your situation.
So what did Greenpeace and their landlord agree upon? Here are some examples of the smart choices that have been made:
- The building is heated using ground source heat extracted by two heat pumps;
- The heat pumps are powered by wind turbines and photovoltaic panels on the rooftop;
- A wood pellet boiler can be used as a backup in case the pumps are unable to provide sufficient heating;
- The cooling load is minimized through highly efficient external shading and;
- Natural daylight is intelligently integrated into the structural design and layout of the building.
Thanks to these and other choices the building has received a Gold Label for Sustainable Building and is awarded the ‘Architecture and Energy Prize’ granted by Germany’s Ministry for Economic Affairs and Energy. If you ever visit Hamburg, don’t hesitate to stop by at Greenpeace to see the office building with your own eyes!
