"Office developers typically invest 2% more when targeting buildings with higher breeam ratings and recover the additional investment in 2-5 years through savings in their energy and water bills"
Breeam aims to reduce the consumption of potable water for sanitary use in new buildings from all sources through the use of water efficient components and water recycling systems.” Credits can be achieved by the use of low flushing WCs for example with 4 litre or 6/3 flushing functions.
Credits can also be achieved by the use of water controls that have low water consumption, for example 6 litres per minute. There are lots of WCs with low water flushing capacities and new technology which helps provide this for a lower Breeam rating.
Within the BREEAM guidelines the section on water consumption states that Credits will be given “where evidence provided demonstrates that the specification includes taps, urinals, WCs and showers that consume less potable water in use than standard specifications for the same type of fittings. Therefore credits can also be achieved for waterless technologies.
