Analysis Assumptions

Cost Estimate & Savings Assumptions

A. Rainwater

A. Payback Assumptions

-Average rainfall data 30-year climate normals from

A. National Climate Data Center OR

B. U.S. Climate Data

-9% increase in annual water rates -2% increase in annual inflation B. Upfront Cost Estimates

-85% runoff coefficient for rainwater collection B. Irrigation water savings

-Cost breakdown by materials and labor based on Hyphae’s past experience, manufacturers, Sweets 2015 cost estimating manual.

-Irrigation water use based on MWELO estimated total water use calculations, approved plant factors, and assumed irrigation efficiency coefficients

-Cost estimtaes provided by contractors provided for generic systems and for specific Eden sites based on site plans and (for some) site visits.

-Reference evapotranspiration values based on data for ETo zones in California -Savings from landscape and irrigation conversion based on literature and landscape maintenance contactor estimates C. Fixture Use Assumptions Toilets -1.6 gallons per flush fixtures -4 uses per tenant per day average Laundry -Laundry water use based on data provided by WASH Multifamily Laundry Systems - calculated from total site revenue collected -For sites with more than one laundry room, it is assumed that all machines are used equally

SCHEMATIC DESIGN ASSUMPTIONS

C. Maintenance Costs -Maintenance costs assume that site maintenance staff are trained to cover regular monitoring and maintenance of all systems (and outside maintenance only called in case of emergency) -Maintenance costs reflect material replacement costs only -Assumed that maintenance cost for landscapes are approximately the same for different types of landscapes (confirmed by landscape contractors)
