The intended savings of 15 percent have yet to be realised. The total water consumptionProcentuele in Gasverbruik 2011verandering was slightly higher t.o.v. 2008 8% in 2010 as a result of the higher than 4% commercial occupancy rate. Additionally, 0% Amsterdam RAI decided to prohibit the -4% use of electric coolers in the halls to save -8% energy and use water coolers instead, -12% which results energy 2008 in a lower 2009 2010 consump2011 tion but a higher waterGasverbruik consumption. Amsterdam RAI is also legally required to flush systems regularly to prevent legionella.
There are several measures planned to achieve the intended 25 percent reduction in water consumption by 2013: • A test with a new water filter and foaming soap, which is expected to reduce water consumption while washing hands by 75 percent. • Amsterdam RAI is looking into an alternative for water cooling. If it is found, water cooling in the halls will be prohibited. • Amsterdam RAI is looking into a new method for managing the risk of legionella that would minimise water consumption. • In the planned new construction, Amsterdam RAI will be using a grey-water system in which rain water is collected via the roof and then used for watering all the plants within Amsterdam RAI.
