Dear Fellow LEED Users, In the Irrigation Design Case tabulation, can I declare "reject water" from reverse osmosis equipment system of campus, as the source of non-potable water? Thanks in advan

We have a project in Scandinavia, where there are no local authority requirements about landscaping. The site is industrial in a rural location.

During a certification process I have found an electronic irrigation controller (model Hunter Pro-C) that is equipped also with a rain sensor (model Hunter Rain-Click).

We are participating in the certification of a building in the Europe Square in L’Hospitalet, Barcelona. The Europe Square area was previously and industrial area.

The reference guide states that the same K_MC value nust be used in botzh design case and basline.

Hi!! Should we include interior vegetation on the calculations of this credit? This a building with several interior plants, including trees that need irrigation.
