Sustainable in every respect
We want our architecture to help to make the world a better place. That is why sustainability is such an important issue at Ector Hoogstad Architects. The healthy, pleasant living and working environments we design are constructed with the aid of sustainable materials, using sustainable production methods, and generate their own energy as far as possible. Our expertise in the field of sustainable design and construction has been proven in many projects over the years, and is still growing. 

We built the energy-efficient town hall in Lelystad as long ago as the 1980s, while in the following decade we developed a smart climate control concept for the Ministry of Housing, Spatial Planning and the Environment in the Hague. We used the BREEAM assessment method to demonstrate the sustainability of our designs before it was introduced for general use in the Netherlands. And we remain leaders in this field: we recently built the first energy-neutral school in the Netherlands, the Focus school in Heerhugowaard. The laboratory we built for the Dutch Institute for Fundamental Energy Research (DIFFER) was the first in the Netherlands to win a BREEAM Excellent rating; and the PULSE education centre we created for Delft University of Technology sets a new standard for sustainable university buildings. 

Our buildings are sustainable in every respect: they have a low environmental impact, and a long life. This is achieved by taking advantage of technological advances on the one hand and the best that nature has to offer on the other. Our buildings have minimum energy requirements, and the materials used in their construction are carefully chosen for minimal environmental impact. Our ambition is to reduce the consumption of building materials still further with the aid of new design and production methods, and to adopt a circular design philosophy in which only used or reused materials are employed in building construction. The timeless appeal of our buildings will, we hope, encourage future generations to keep on using and reusing them for a long time to come. 

The main contribution we make towards the achievement of real sustainability is our undogmatic, open attitude that helps us to arrive at smart, all-embracing solutions. We are ready for the next generation of sustainable buildings – energy suppliers based on continuous recycling of materials.
