Abstract

Every decade the Dutch horticulture has a great exposition event, the 'Floriade'. The next Floriade 2012 will contain a greenhouse characterised by ergonomic office workplaces in a green surrounding. Normal offices are located within the greenhouse in different climates including particular vegetation.

This literally and environmentally greenest office is also the greenest building in the Netherlands, lacking public utilities, except ICT. The size of the building is 42,500 m2. A low glasshouse roof on the south side climbs up till six floors of office on the north side. The silhouette of the building is dominated by large parabolic solar collectors.

The seasonal surplus of heat and cold from the solar power system is stored in the aquifer approximately 50 m beneath the building. The building is equipped with a heating system based on very low-temperatures (24-25 ŻC), enabled by fine wire heat exchangers recently invented. The cooling of the indoor climate in summer is based mainly on the same system.

The vacuum sewer system and organic waste collection are aspects of ecological innovation. By means of an anaerobic bioreactor and a micro-turbine, electricity can be produced on location with addition of organic waste.  The filtered exhaust gases are used as nutrients up till 1,000 ppm, in order to take care of the CO2 balance. Pure water can be retained within this process, which takes two or three days.

The parabolic solar collector roof construction is the most visual innovation. During a 24 hours period a new coating on mirrors enables the harvesting of boiling water and PV electricity on a sunny day and cold and condensing water by clear night sky.

In a country of regulation the Dutch government needs to decide on the building permit for this building that will not be plugged into public utilities. The paper will discuss all issues related to the trail-blazing Floriade greenhouse.

SB08 congres Melbourne

28-oktober-2008   (door:Wim Welmer)
Dit evenement met de belangrijkste partners van de CSIRO, Duurzaamheid Victoria, de United Nations Environment Program, het Internationaal Initiatief voor een duurzame gebouwde omgeving (iisbe) en de International Council for Research and Innovation in Building and Construction (CIB) werd van 21 tot 25 september 2008 gehouden in Melbourne en door ons kantoor bezocht door Jon Kristinsson en Wim Welmer.
Door Jon Kristinsson werd een lezing gehouden over The greenest office in the Netherlands (Floriade 2012)
De voordracht kreeg veel bijval doordat het verder gaat dan "Cradle to Cradle". Ook voor de toepassingen van de innovatieve laagtemperatuur technieken van de energieproducerende kas (fijne draadwisselaars) en de anaŽrobe vergisters bleek veel belangstelling te bestaan in het buitenland. Kortom een succesvol congres.
