Litres Arlanda airport, Sweden Over a period of o
ne year, the Swedish National Aviation Administration (Luftfartsverket) carried out tests at Arlanda airport which compared conventional single lever mixers with mixers equipped with the Mora ESS energy saving system and Mora Eco, to study the potential for energy and environmental savings. • The tests were performed in the most frequently used public toilets in Terminal 4, where flow meters for hot and cold water were installed on four washbasins. • The results showed a 60 percent reduction in hot water consumption. Average daily consumption during the measurement period 150 58 l CW 125 (38,4 %) 100 75 92 l HW (61,6 %) 50 25 35 l HW (27,6 %) Conventional single lever system Mora ESS single lever system Energy calculator – moraarmatur.se A four-person family can save over SEK 4,000 a year by making energy-smart choices.
