The most environmentally friendly cistern usingÊa free, sustainable water supply that has previously been drained to waste.
Water savings
Data from hotel specialist STR Global shows 93,984 rooms in 302 hotels are currently being built in the MENA region.Ê Compared to traditional cisterns, using Encore would save the average 311-bed MENA hotel 7.9m litres based on standard 80% occupancy levels.Ê In total, Encore would save them 2.4bn litres of water a year, filling the equivalent of 960 Olympic swimming pools.
How it works
Encore holds 18-litres of water – three times more than a conventional cistern but its dual-chamber design means it fits like standard models.ÊThe bottom chamber holds 6-litres, which comes from the mains pipe.ÊÊThe upper 12-liter chamber is filled with air conditioning condensate.ÊWhen the toilet is flushed, the lower chamber empties then refills with condensate from the upper chamber.ÊIf there are multiple flushes close together or the air conditioning is not in use, the cistern is filled by the mains fed pipe.ÊIf the toilet is not used for a period, surplus condensate is fed away.
Invention
Encore was invented by David Davis and Graham Kelly, directors of the UK-based G&H Group, a £25 million Building Services company.
“For decades we’ve designed and installed schemes and watched the stream of water produced by air conditioning units literally go down the drain but not via the toilet,” adds Mr Davis. “Responsible businesses striving to construct the greenest buildings know how hard to get LEED and BREEAM points are.
