A selection of the remarkable, sustainable projects in which Deerns has been involved as consultant.
Duindorp residential area, The Hague
A concept for heating houses by extracting heat from seawater. The over-all return from heat generation with this system is 50% better than with conventional high-yield boilers. Completion 2005-2008
De Brug (Unilever head office), Rotterdam
Heating and cooling by river Maas water.
New City of Dehsabz (Kabul), Afghanistan
Study into a sustainable energy infrastructure for a city area of ca. 40,000 hectares.
Station and city offices Delft
A design that performs 35% better than the EPN-norm requirements.
Martini Hospital Groningen
After renovation, the present building’s energy consumption will be reduced by 48%.
The new building (completion 2007) is in the top 3 of low-energy hospitals in the Netherlands.
Central Station Utrecht
Study into sustainable energy supply for shops in the station area.
Zero energy building Suntech, China
By applying a mix of sustainable energy generation and systems, some 80% of the energy demand will be generated in a sustainable way.
Port of Antwerp, Belgium
Study and pilot project into heating buildings with water from the port.
The "Balanced Greenhouse"
A concept for energy-efficient and CO2 neutral heat exchange between houses and greenhouses.
Interior gardens form a buffer between the outdoor climate and offices. In winter the naturally preheated air is used to ventilate the offices. In summer plants and water cool the ventilation air through evaporation.
Burj al Shams (Tower of the Sun), Concept
Concept for an energy neutral tower. With special attention paid to, amongst other things, the specific shape of the building, the efficient use of solar power, and smart daylight features.
