The Conference Center
Reducing Water Consumption
The CHI Conference Center has one of Europe’s largest herbaceous plant rooftop gardens!
🌻 It not only adds ecological value, but also retains rainwater to water the adjacent park and serves as a habitat mainly for insects 🐛
🌻 Eco-friendly cleaning agents to minimize pollution and reduction of water consumption is a top priority
🌻 The CHI Conference Center uses water-saving fixtures to reduce water flow rates and rinse volumes
Reducing Power (Electricity) Consumption
Light up – in an eco-friedly way!
💡 The state-of-the-art LED lighting and media technology used by the CHI Conference Center is extremely energy-efficient.
💡 100% eco-friendly energy generated from water or wind power since 2011
Reducing Energy (Heating) Consumption
Did you know you can recycle heat? The CHI Conference Center is doing just that!
♻ 99% of the energy we used for heating the buildings is recovered waste heat from the district heating network
♻ The exhibition halls are equipped with waste heat recovery systems to reduce thermal losses
♻ The cooling effect of the adjacent “Planten un Blomen” park is used to minimize the need for artificial night-time cooling during the summer months
♻ The heating, ventilation and air conditioning systems of all halls can be controlled individually to avoid wasting energy in unoccupied rooms.
Think outside the trash…Recycle!
In the CHI conference centre…
🗑 Wherever paper is required, recycled paper is used
🗑 There is no plastic cutlery or other plastic eating utensils
