Calculations and
Methodology
the overall landscaping plan;
� System specifications including cut sheets and/or manufacturer’s specifications
for the following equipment:
� Override sensors;
� Backflow valves; and
� Separate meters.
� Drawings showing the location of each device on a site plan.
Recycled Water
� Completed Building Water Calculator confirming that 100% of the exterior irrigation
demand can be served using the Exterior Water Allowance; and
� A composite utility schematic illustrating routing of recycled water mainline and
laterals.
Schools Only
� Confirmation that all playing fields use turf substitutes requiring no irrigation
water;
� Site plans indicating location and size of playing fields; and
� Specification/manufacturer’s details of turf substitutes.
� Revised As-Built documentation as per Design Rating; and
� Photographs of the installed irrigation systems, landscaping, school playing fields
(where applicable), water recycling systems (where installed) and routing of
recycled water mainline and laterals indicating their color code.
Plant Selection
� Landscaped area refers to the plot area excluding the building footprint and all
water feature / swimming pool areas, and is made up of all hardscape and
softscape areas. Where communal rooftop amenities are provided (e.g.
podium/skylight gardens), any landscape associated with these spaces must also be
included in the calculation.
The average irrigation demand for all landscaped areas is calculated as follows:
AP = Plot Area,
AB = Building Footprint Area,
AS = Softscape Area (grade level)
AW = Water Feature/Swimming Pool Area (grade level),
ARA = Roof Amenity Area
ARS = Softscape Area (roof level),
ARW = Water Feature/Swimming Pool Area (roof level)
