Gather Information/Data • Utility bill data • Building characteristics & site info
Agenda – Today’s Adventure
Prioritize Project Rollouts
• 5 factors to consider
Measure & Report Results
• KPIs • Frequency
Gather Information/Data
Utility Bill Data − Consumption or usage − Rates
Building Characteristics & Site Information − Operating divisions (districts, regions, etc.) − Existing systems & equipment − Gross floor area (sqft) − Site type / site profile / property characteristics − Energy Drivers (transactional data)
Fuel centers Open vs. closed cases Refrigeration controls
Amenities Occupancy Guest room
fixtures & controls
Building Characteristics & Site Info
Landscaping Hood size & type
Lighting
Site type Brand
Lighting HVAC controls
Water Projects
Restrooms − Aerators − Urinals, Toilets − Showerheads
Kitchens − Aerators, PRSV − Steamers − Ice machines − Dishwashers
HVAC − Cooling towers, boilers − Evaporative cooling
Refrigeration − Ice machines − Walk-in cooler
Irrigation − Native vegetation − Efficient systems − Smart irrigation − Rain sensors

Prioritize Project Rollouts
5 Factors to Consider: 1. Region
2. Utility rates
3. Consumption/Usage
4. Utility incentives/rebates
5. CO2e
Don’t forget about timing!
1. Region
More Sites Fewer Sites
2. Utility Rates
Higher $/kWh Lower $/kWh
3. Consumption/Usage
More sites with unfavorable performance Fewer sites with unfavorable performance
4. Utility Incentives/Rebates
Higher Rank Lower Rank

Prioritize Project Rollouts
• 5 factors to consider
Example A: Interior Lighting Project
Project – LED retrofit
Data and Information – Utility bill consumption and cost data – Utility rates by location – Existing lighting inventory
Prioritization Methodology – Region – Utility rebates – Utility rates
Measure & Report Results – Quarterly kWh/sqft and $/sqft – Annual % change to baseline
Results: Saks Fifth Avenue
Project – LED retrofit
Results – 23% annual energy reduction
at participating stores – Over $1M in savings
Motivation – Public demand for change
(sustainability) – Government incentives – Energy efficiency technology
Example B: Water
Project – Aerators, pre-rinse spray vales – Smart irrigation and rain sensors
Data and Information – Water bill consumption and cost data – Landscaping – Equipment inventory
Prioritization Methodology – Region – Utility rebates – Utility rates
Measure & Report Results – Monthly performance reporting – Year over year comparison
Results: Shari’s Cafe and Pies
Project – Aerators , pre-rinse spray vales – Heated dipperwells – Smart irrigation and rain sensors – ENERGY STAR dishwashers – Submetering
Results (2009-2014) – $1.8M avoided cost – Over 66 million gallons saved
(100 Olympic pools!)
Motivation − Utilities 4% of total costs − Stewardship − Municipal water tax
