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

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

Measure & Report Results

• KPIs • Frequency

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
