    Does anyone have any thoughts (intelligent or otherwise) on how best to design an irrigation system to support a commercial building getting LEED certification? I just won a bid on supplying the irrigation, now they've come back to me asking me to supply an alternate price based upon trying to support a higher LEED rating.

    So.. anyone done anything in this area?

    I had pretty much figured on an ET controller and doing drip for the shrubs, tree bubblers on trees. The biggest challenge appears to be the few areas of turf. I really don't like the thought of putting down miles of netafim for the turf... even at nice commercial rates....

    i'm suprised with the LEED they are even putting in irrigation, the whole premise with that is to minimize energy use so they stress drought resistant shrubs and grass

    what might be a possible is to suggest catching all of the roof drains into under ground holding tanks then using that to irrigate with

    Definitely a big part of the LEED environmental aspect is to use hardy native materials.

    I don't think the city planning commission gives a damn about that. They force all commercial buildings to have irrigation; any multi unit housing must have irrigation, etc. If the planning commission feels that a place won't be occupied by the owner, they force irrigation as part of the permit approval to ensure that the grass gets watered. Other than being the beneficiary of this, I have mixed feelings to the approach.
     
  7. RainBird Sam/prs spray heads, I-20's or rotors with check valves for lowend drainage , rain sensor, freeze sensor, wind sensor, Et controller, drip irrigation- etc... Like you stated..also system set up with correct hydrozones ...anything on the premise of "water conservation"...
    I was just talking with a friend about Leeds this past weekend....

    they will take a hit on their points rating with any type of irrigation so as long as you eliminate run off then you should be good

    i have sat through so many lectures and readings on all this LEED crap it boggles my mind...for the amount of time, money, and materials it takes to get these buildings to achieve any type of LEED rating i would like to see some real numbers on energy savings and how long it takes to make back their money, rather then the theoretical numbers they always give
