Dear LEED-experten,
has anyone experience about the low-flow lavatory faucet on the restroom washbasin in Europe? Actually the LEED-baseline has a much lower value (2 l/min) than the European standard value (normally up to 5l/m bis 7l/min).
We has planned to install the aerator on the facet to reduce the flow-rate on the same pressure condition, same as the other leed project in Europe. But we’re wondering if this measure really has the benefit for our project? When a project located in a developed campus und has the existing sewage systems and pipes, the too low waste water flow will not complain with the certain filling ratio of the pipe, it is also a risk to damage the pipes.
Has anyone some advices or idea about this situation?
Thank you very much in advance.

I don't have direct experience with this situation. I would simply advise that this and other issues with low-flow fixtures have cropped up relative to LEED and building code issues, so you would not be alone in having this concern. Although I'm not qualified to speak to the specific technical issue, I don't think anyone, including USGBC, would advise you to pursue a LEED credit at the likely/potential expense of major impact on infrastructure -- which would, if it came about, have its own environmental burdens. I would also weigh the environmental benefit of lowering the water usage. This is not equally a priority in all parts of the world.
