consumers of water and electricity are individually
metered and monitored to avoid waste and modify
behaviours as necessary. Water efficient fittings
reduce potable water consumption, as does
recycling of fire test water. Lighting occupancy
sensors and limited power density keep a rein
on electrical energy usage, and the kitchens run
