WE P1 - Water sense as a must have

It will be an prerequisite to only use toilets, urinals and private lavatory faucets and shower heads, which are Water Sense labeled. The water sense label basically sets a maximum flush/flow rate and requires independent testing of that and the map test, just to name a few things. I think it's great to finally restrict flows per fixture and have a form of verification as to function of the fixture. So the reduction doesn't scarifies the function. However I'm working on lots of international projects and get lots of questions from international teams in regards to where they can find products that can even help meeting the current LEED requirements. If we add even stricter limits and additional certifications to that. It will be impossible for many projects to meet the minimum requirements. So to be more specific: toilets shall not exceed 1.28 gallons ( 4.8 liters). In Germany you need an exemption from the public sewer district to use toilets below 5l, which be the way usually gets denied. Urinals: 0.5 gpf (1.9 liter) Shower 2 gpm (7.6 liter) Private faucets: 1.5 gpm (5.7 liter)at 60 psi, not less than 0.8 gpm (3 liter) at 20psi In Europe they are just getting started with certifications that would cover this, but it's a long way to have just a few products to choose from that would meet the requirements for this prerequisite. If my current projects in Europe would have to use LEED 2012, they would not be able to unless they import products form the US, which don't have the required testing labels to used in buildings, which want to ever get a property insurance. So de facto I would not be able to meet WE P1.
