The IUCN Story
SOME KEY FACTS AND FIGURES
• Ground external surface: 7,000 m2
• Built surface 3,400 m2
• Gross floor area surface: 5,400 m2
• Atrium, terrace and balcony: 1,900 m2
• Parking in the sub-basement: 2,200 m2
• 25 million Swiss francs
• Over 130 workspaces on 2,000 m2
• Through all aspects of design and construction, IUCN is working to achieve the highest U.S. Green Building Council standard rating: LEED Platinum (Leadership in Energy and Environmental Design). IUCN’s goal is to be the first office building in Europe with LEED Platinum certification. www.usgbc.org/LEED
• MINERGIE-P-ECO®. The MINERGIE standard is a voluntary, Swiss-based construction standard that promotes the rational use of energy and use of renewable energy sources. It mitigates negative environmental impacts and sets high demands in terms of comfort. www.minergie.com
• High efficiency drinking water system
• Rain water is collected on the roof and used to flush toilets and irrigate the garden
• Waterless urinals
• Geothermal heat pump reversible: 15 wells at 180 meters deep.
• Heating and cooling through thermal mass of concrete
• Production of hot water through recuperation of heat on refrigerators.
• 100% of the energy consumption comes from renewable sources
• A photovoltaic installation producing 145MW per year.
• 27% of that energy is used to run the building, which covers 20% of its total energy need.
• The most innovative and low consumption lighting system available: EU Energy Label – Class A
• Presence and daylight sensors to optimise the use of artificial lighting
• Maximization of daylight through skylights
Materials and Resources
• Minimal use of materials - no cladding or painted surfaces
• 40% of concrete from recycled sources
• Innovative use of thermal concrete to reduce heating energy consumption
Indoor Environmental Quality
• A building and site that explicitly supports a healthy work and lifestyle, interaction and innovation.
• A decentralized CO2 controlled air supply system.
• Balconies and adjustable blinds to avoid overheating in summer and allow passive solar gain in winter, while taking advantage of natural light.
• Climate control system which draws fresh air from the balcony that surrounds the top floor
