Agenda 1. Identify (Drought) Opportunities with Facility Survey 2. Resources for Benchmarking Efficient Technologies 3. Case Studies of Audits (with Training) University of San Francisco, California Honolulu Board of Water Supply, Hawaii 4. Lessons Learned for Drought Response 5. Questions 2
PART 1: Conduct Facility Survey Typical CII Customer Types Government Facilities Offices Grocery Stores Shops Restaurants Automobile businesses Microbrewery Hotel/Motel Schools Parks/Greenbelts Honolulu District, Oahu, Hawaii 3
Summary of Steps to CII Survey Step 1. Line Up Support and Resources (water utility) Step 2. Take Immediate Action, Do the Obvious First Step 3. Conduct Water Survey (with utility support) Step 4. Identify Water Saving Opportunities Step 5. Prepare an Action Plan Step 6. Implement Measures Step 7. Document Findings Step 8. Complete Communication to Water Utility and then Publicize Success
Step 1. Line Up Support and Resources Get Top Management Support Stress benefits of saving water/energy Develop Management Actions Get Employee Participation Get Outside Help
Step 2. Take Immediate Action, Do the Obvious First Look for leaks and fix them Read meters during no activity periods Inspect facility Leaks on process plumbing Leaks on toilets and faucets Eliminate Waste and Unnecessary Uses Install timers Eliminate unnecessary hot water Simple retrofits to save water
Step 3. Conduct Water Audit Preparation Identify key persons Gather records Understand the Site Determine Value of Saved Water Energy and chemical bills Water & wastewater bills Water Use, gal/day 30,000 25,000 20,000 15,000 10,000 5,000 0 Jul-97 Oct-97 Jan-98 Apr-98 Jul-98 Oct-98 Jan-99 Apr-99 Hospital X Water Use History Jul-99 Oct-99 Jan-00 Apr-00 Jul-00 Oct-00 Jan-01 Apr-01 Jul-01 Oct-01 Jan-02 Apr-02 Jul-02 Oct-02 Jan-03 Month-Year Bimonthly Consumption Linear (Bimonthly Consumption) 12 per. Mov. Avg. (Bimonthly Consumption)
Step 3. Conduct Water Audit Survey the Facility, may ask for utility staff support Make a Water Balance, if needed Quantify or Evaluate key use areas: Cooling Process Sanitary Cleaning Ice Machine Kitchen Landscape Irrigation Cooling Tower / Boiler / Ice Chiller 15% Dialysis and X-Ray 3% Sterilization/ Autoclave 7% Ice Machine 3% Hospital X Water Balance Kitchen Use 11% Leaks 9% Faucets 5% Toilets 24% Showers 4% Urinals 8% Misc. Cleaning and Hospital Use 11%
Step 4. Identify Water Saving Opportunities If feasible, install meters at high flow points Water efficient equipment Recirculate process water Identify uses for non-potable Water Treat and reclaim/recycle water
Step 5. Prepare and Action Plan Evaluate Water Efficiency Measures Costs and Benefits Payback Periods Prioritize Measures including meeting criteria in the Green Business Checklist Example: Sacramento Sustainable Business http://www.sacberc.org Develop budget and schedule Quantify goals (save % by certain year) Identify implementation responsibilities Submit a Plan to top management for review 10
Step 6. Implement Measures Get top management approval Make funding available Allocate resources Set-up monitoring program
7. Document Findings/ Complete Green Business Checklist Different Checklists for: Hotels & Resorts Office and Retail Restaurant & Food Service http://energy.hawaii.gov/wp-content/uploads/2011/10/hotel-resort-checklist-rev.12.2011.pd http://energy.hawaii.gov/wp-content/uploads/2011/10/office-checklist-rev.12.2011.pdf http://energy.hawaii.gov/wp-content/uploads/2011/10/restaurant-checklist-rev.12.2011.pdf
Step 8. Complete Site Verification and Publicize Success Complete site verification walk-through with Green Business Team Receive Reward for Achievements Announce and proudly display the certification!

PART 3: Case Study #1: Large CII Audit University of California, San Francisco (UCSF) Medical School Project Goals Create complete water fixture inventory of 5.4 million building square feet Provide prioritized list of recommended cost effective conservation projects with costs & savings Summary report and tables in final written audit report 22
Benefits of using Water Audit Tool for Inventory and Tracking Changes Efficient electronic data entry in the field No transcription time or errors Provided MS Excel database to management staff so know exactly which fixtures need to be replaced / repaired Serves as a tracking inventory when changes made 23
Highlights of Tablet Technology Three main types of tablet platforms: 1. Windows 2. ipad 3. Android Not all tablets are created equal Windows 8 Not all tablets have the same battery life Not all tablets can run Microsoft Excel Not all tablets are the same cost $$ Software written for one tablet cannot run on another ipad 24
Electronic Data Entry for UCSF: Potable and Non-potable water systems Medical teaching facility School of Dentistry School of Optometry Hospital + Clinic Extensive Medical Research Steam Sterilizers / Autoclaves Laboratory faucets Toilets Urinals Library / Classrooms Toilets Showers Faucets Food Court Spray Valves Ice Machines Dishwashers Athletic Center Pool Laundry Showers Faucets Toilets 25
Overview of Water Audit Software 5 Basic Steps to the Water Audits Software MS Excel Application: 1. Enter Basic Site Data 2. Select Area with Water Using Equipment / Fixture ( Rooms ) 3. Enter Equipment / Fixture Data 4. Review List of Projects & Summary Data 5. Report Summary Graphs / Tables / Charts 26

Case Study #2: Hands-on Training Session Honolulu Board of Water Supply: Waikiki Prince Hotel Project Goals: CII audit training over 3 days with 24 attendees from all Hawaiian Islands Attendees learned equipment & recorded data electronically during training including MWM Water Audit Tool 36
Electronic Data Entry for the Prince Hotel: Sample of 521 Hotel Rooms Faucets Toilets Showers Cooling Towers Pool (Outdoor) Fitness Center Public Restrooms Wash Down Food Service 3 restaurants Pre-Rinse Spray Valve Dishwashers Ice Machines Landscaping On-site Laundry Water Features Meters Leaks 37
Paperless Review of Prince Hotel Water Use History 2006-2011 (gallons per day) 38
Benefits: More Connection to Training Concepts & Efficiency Levels Training attendees learned data with real time results for fixture flow rates Very helpful to reinforce levels of efficiency Detail needed for documentation and photos Hotel provided the software with list of projects Lobby bathroom and other plumbing fixtures Landscape improvements Cooling tower adjustments On-site laundry upgrades (supporting justification) Kitchen equipment (dishwashers, defrosting methods) 39
More Benefits: Creditable Findings & Follow-through on Recommendations BWS reviewed the software and findings along with providing written suggestions with hotel staff Hotel maintenance staff received robust justification for more investment from property owner Validation Tool for Green Business Certification Overall more follow-through on audit recommendations Irrigation Audit Training in Hawaii, July 2013 40

Lesson Learned #1 All Stylus are not created equal Does NOT work well! Rounded stylus tip is very difficult to use Having a stylus port is useful so it does get lost Pointed tip stylus pen much easier! 43
Lesson Learned #2 An external battery charger is useful External battery pack works for full day of audits Multiple types of ports allows tablets, laptops and phones! 44
Lesson Learned #3 Screen size is important Ideal screen size is minimum of 1280x800. The new Microsoft Surface Pro 2 planned is available and is 1920x1080. Smaller screens are difficult for data entry. Smaller is not always better! 45
Lesson Learned #4 Neck strap helpful with arm fatigue, safety of the tablet (dropped) 46
Lesson Learned #5 Use of photos in the field Photos help for verification of the model and serial number when back in the office Photos of the site are a nice addition to individualized site reports 47
