The Process
Obtain Energy
Star Rating
Create Energy Plan: Manage Energy Costs, Energy Star & LEED-EB
Understand Building Characteristics
Reduce Energy Usage & Costs
Create Sustainable Energy Program
Go For Energy Star Certification
Use Energy Star For LEED-EB Certification
Market Energy Star Rating
Setup LEED-EB Management
Incrementally Improve Energy Star Rating
Track Energy & Bldg Operations
Itemize, Track & Manage LEED-EB Points
Market LEED Certification

Getting Started
First: Obtain Energy Star Rating• Twelve months of utility bills
• Building construction information
Second: Understand Building Characteristics• HVAC system
• Temperature control operations
• Generate list of potential energy measures
5
Energy Plan
Five Fundamentals1. Establish an Energy Policy
2. Create Awareness Program
3. Manage Space Usage
4. Measure & Verify Energy Performance
5. Track & Evaluate Equipment Performance

Managing Energy Costs
Getting Started Utility Tariffs
• How energy costs are charged
• Demand is usually separate charge (~ 50%)
Utility Bills• Complex charges
Billing Data• Collect demand and usage as well as cost
• Include billed and actual demand charges
13
Energy Star
Leveraging Energy Star
EPA national rating service Percentile rating method Energy Star is national
benchmark Use to reduce actual energy
usage & cost Improve LEED-EB rating
14
Energy Star Impact
Improved Building Valuation * Up 30%+ ($352 vs $290 per sf)
Improved Building Lease Rates * Up $2.00 to $2.35 per sf

Example: from four previously audited buildings, we evaluated the multiplying effect where the ratio of total savings plus rental rate increase produces ratios of 3.40 to 6.00 – a huge multiplier over energy savings alone.
The results of the CoStar study show that every $1.00 saved in energy cost can produce $3.40 to $6.00 in total annual value. This level of return significantly improves classical payback calculations.
Add premium sales price for high Energy Star rated buildings and….
Every energy $1 saved can yield an additional $10 to $20 in building valuation over 5 yrs.

Obtaining LEED-EB
Certification Levels Certified 34 – 42 points Silver 43 – 50 points Gold 51 – 67 points Platinum 68 – 92 points
Start with Certified – minimum 34 points
Leverage Energy Star – up to 15 point contribution
17
Energy Plan & LEED-EB
Energy & Atmosphere – 30 points 15 points for Energy Star rating 3 points for Performance Measurement
Indoor Environmental Quality – 19 points
5 points for Indoor Air Quality 5 points for Occupant Comfort
