Sustainability has been a central theme of Foster + Partners' work for more than 40 years. To remain at the forefront of advances in sustainable design, our Research and Development Group includes a multi-disciplinary Sustainability Forum and dedicated Sustainability Co-ordinators. We consider environmental performance holistically: from the embodied energy of materials to life-time energy performance. In many of our projects, we have pioneered renewable energy solutions, which have offered dramatic reductions in pollution and carbon emissions. Working with industry, we have created a new generation of super-efficient wind turbines and new forms of cladding systems that can harvest solar energy.
