WWF Netherlands is world’s first zero carbon building
The headquarters of the Netherlands chapter of the World Wide Fund for Nature was completed in October 2006. It also happens to be one of the single most sustainable buildings created in recent years. This building is claimed to be the world’s first zero carbon building because it is naturally ventilated and it also obtains its heat requirements from staff and equipment in the office while the solar arrays provide electricity and hot water. A backup biomass system is also in place. The ceilings are moisture-balancing made of mud with continuous circulation of water through little glass tubes taking care of the spreading of human and mechanical warmth and also the cooling. All materials that are used are scanned for environmental friendliness as well as for child labor. The building also has bird friendly roofing tiles and bat basements.
