What irrigation efficiency should be used for hand watering?

Hi we are attempting this credit for one of our existing schools project.The project does not have permanent irrigation system.The landscape area is irrigated manually by the facility staff member

If we install subsystem metering for the irrigation systems to comply with WEc1 can we follow the “Non-Metered Irrigation” option at WEc3?

For a project where turf grass area is replaced by native low-irrigation demanding planting would baseline landscape type include turf whereas design type include the new water efficient species?

My team and I are in the appeal phase for our project. WEc3 was denied because the total area of exterior landscaping is 3,276 square feet, which is less than 5% of the total site area and therefor

Hi, We are using 100% treated waste water for irrigation. It is not sub metered and therefore we are trying to use the option 2.

I'm looking for a calculator or guide that would suggest how much rainwater could be collected in Mid-summer or the month with the highest irrigation demand.

Some portions of the site are irrigated, while other areas are not. Non-irrigated areas include adapted grass,shrubs and trees which are shaded by the building and do not need irrigation.

I'm working on a building with a large portion of natural vegetation which is not irrigated. There is also a separate area of turf, trees, shurbs that is irrigated.

The intent of the credit says "To limit or eliminate the use of potable water or other natural surface or subsurface resources available on or near the project site for landscape irrigation." I ha
