6. Why And How To Track Water Usage • Why? • Helps owners understand how much is used by a building to target retrofits and conservation. • Helps owners compare building is normalize data per person or per bedroom. • Triggers water conservation actions to save owners money and save water. • How? • Collect and input water data. • Explore benchmarking/tracking software. • Review data monthly or quarterly, when new data are entered.

8. Tracking Water Expenses Annual Boston Area Water Expenses per ApartmentSometimes usage in gallons is not available, dollars provide clues about extreme use 5 to 1 ratio in expenses from about $1500/apartment to low of $300/apartment

9. Key Steps to Benchmarking • Gather water bills. • Confirm meters for each building. • Enter data in tracking software or spreadsheet. • Examples of benchmarking software for water and energy: • www.wegowise.com • www.psdconsulting.comBuilding Performance Compass • www.brightpower.biz

10. Myths Or Realities Of Water Usage • Shower use accounts for the greatest amount of water used by most people (excluding irrigation). • Toilets installed before 1993 use nearly twice as much water as toilets available in 2010. • Low flow toilets just don’t work. • Water conservation can yield significant savings.

11. Daily Water Use Targets Super Water Conserver: <44 gallons/person <66 gallons/bedroom* Good Water Conserver: <55 gallons/person <83 gallons/bedroom* • Poor Water Conserver: • >55 gallons/person • >83 gallons/bedroom* Sources: American Water Works Association (2010) & Steven Winter Associates *Targets assume 1.5 people per bedroom

12. Water Saving Opportunities for Owners Leaks: Fix problems that are wasting significant water. Check usage data for spikes. Check meters at 3 am, when usage is low to identify leaks. Low Cost Upgrades: Effective actions in most properties: repair toilet flappers; install low flow showerheads and aerators. Rehab Opportunities:Replace toilets (especially 3gpf) with EPA WaterSense, upgrade clothes washers with WaterSense equipment, complete upgrades in #2 above.

13. 1. Fix Leaks • Leaking toilet could waste 100 gallons/day • Faucet leak 1 drip/second wastes 5 gallons/day • Hot water leaks waste water and energy • Leaks account for 14% of household water use • Severity of leaks can be found by looking at your water meter at 2am • Water running at that time is typically from leaks

14. 2. Repair or Replace Toilets • New Toilets – Use EPA Water Sense 1.28 gallons/flush (gpf) • Existing Toilets – Fix leaking flapper or replace pre-1993 toilets using > 3 gpf Flapper

15. Evaluate New Toilet Performance • Consult MAP (Maximum Performance) testing annual study for detailed results: • Water use • Performance in flushing solid matter • Download MAPT results from www.map-testing.com Simulated solid matter for toilet testing

16. 3. Replace Faucet Aerators • EPA Water Sense Aerators 1.5 gallons/minute (gpm) • Or better in bathroom, try .5 gpm • Water pressure can affect performance, test aerator

17. 4. Replace Showerheads • EPA Water Sense 2 gpm • Or better: <1.75 gpm

18. 5. Use ENERGY STAR Clothes Washer • Use ENERGY STAR Washer • Use 30% less energy and over 50% less water than regular washers

19. EPA WaterSense Program • Labeled products 20 % more water efficient • Products tested & listed on website www.epa.gov/watersense • Products include: • Toilets • Showerheads • Faucet aerators • Urinals

26. Water Case Study #2: Retrofit Payback • Retrofits in 14 buildings, including: • Fix leaks • Replace toilet flappers • Install low flow showerheads (1.75 gpm) • Install low flow aerators • Payback is under 6 months. Source: WinnResidential

27. What Would You Do? • Complete Exercise Water Conservation 1 • Review baseline conditions: • Water usage 92 gallons/person/day • Toilet: 5 gpf (leaking) • Showerhead: 4 gpm • Kitchen Sink: 2.5 gpm • Bath Sink: 2.5 gpm • What is the water use & payback for the below actions: (use spreadsheet package #1) • Showerhead: 2 gpm • Kitchen Faucet: 1.5 gpm • Bath Faucet: 1 gpm • Toilet: 3 gpf (assumes flapper repair to 3 gpf existing toilet achieves 3 gpf)

28. How Does Toilet Replacement Affect Payback? • What is the water use & payback for the below actions: (use spreadsheet package #2): • Showerhead: 2 gpm • Kitchen Faucet: 1.5 gpm • Bath Faucet: 1 gpm • Toilet: 1.28 gpf (WaterSense approved) • How does replacing the toilet versus repairing the existing toilet affect payback? • Note we assume $450 for toilet replacement costs (parts and labor – you can adjust these assumptions) Try a package of your own design.

29. Property Management Actions • Review baseline data & target high users > 83 gallons/bedroom/day • Repair leaks • Fix running toilets • Install low flow faucets • Install low flow toilets • Install low flow clothes washers • Reduce irrigation • Finance internally or use 3rd party

31. The Checklist Benchmark & target high use buildings> 55 gallons/person/day or 83 gallons/bedroom/day Fix leaks Upgrade water fixtures:showerheads, faucet aerators, repair toilet flappers or replace pre-1994 toilets (or others using > 1.6 gpf) Specify ENERGY STAR clothes washers Minimize water for plantings:Avoid irrigation and use draught tolerant plantings

32. Review Learning Objectives • Understand the value of tracking water usage • Identify 4 significant water usages in buildings • Identify 3 actions property managers can take to conserve water • Understand how to evaluate the cost effectiveness of water conservation strategies
