Hi,

according to Reference Guide, if smart-sensor technology that meets WaterSense criteria is installed in project, additional 15% savings can be claimed. Tipically this controls can include:

1) optimized zoning and schedules;

2) rainfall sensors;

3) soil moisture sensors.

Can you please confirm that having only one of the above referred componentes labled by WaterSense is enough to get the 15% savings against baseline?

Regards,

Hi Pedro, The reference guide doesn't specify which smart sensor technology needs to be used, only that it meets Water Sense Criteria. To my best interpretation, it would appear that as long as you have one control which meets the Water Sense Criteria (found here: https://www.epa.gov/sites/production/files/2017-01/documents/ws-products-minireport-irrigation-controllers.pdf ) then you can get this 15% additional savings.

Hi, How do I calculate the 15% additional savings due to smart controls? To the best of my interpretation, I am calculating 15% of prerequisite LWR. By "prerequisite LWR" I am considering 70% of baseline consumption. Is this correct? thanks!

Pedro, are you using the Water Budget Data Finder to estimate your baseline? If you're going for a 30% reduction, then 70% of a baseline consumption seems correct. Then, the reference guide gives this equation for Smart Sense controls: Final LWR = LWR or Adjusted LWR – (.15 X LWR or Adjusted LWR) The adjusted LWR would be your 70%. So I think by this, you automatically get a 15% reduction if you use WaterSense Smart controls.
