TRANSCRIPT
ENERGY STAR Program
1. Joint program of the U.S. Environmental Protection Agency and the U.S Department of Energy - 1992.
2. Helps individuals, organizations, property managers and owners adopt cost-effective energy efficient technologies to manage energy costs and address climate change.
ENERGY STAR Program
• Credible and objective source of information.
• 3rd party verification of products and building energy performance.
ENERGY STAR Buildings
• Consume less energy
• Cost less to operate
• Provide utility bill savings
• Reduce carbon emissions
• Avoid the need for new power plants
ENERGY STAR results represent 1/3 of the total greenhouse gas emission reductions from the U.S. Climate Change Program
ENERGY STAR and Global Climate Change
ENERGY STAR 2006 Statistics
• Prevented 37 million tons of greenhouse gas emissions
• Saved 14 billion on utility bills
• Helped to avoid 35,000 megawatts of peak power
ENERGY STAR 2006 Statistics
• 3,200 buildings with Energy Star label
• 575 million square feet
• 35% less energy use
• Saved 600 million on utility bills
ENERGY STAR 2006 Statistics
• 300,000 buildings were rated using EPA’s energy performance rating system.
• 5 billion square feet
• 42% Hospital Space, 30% Supermarket Space, 18% School Space, 25% Office Building Space.

• Commercial buildings can generate $2.00 to $3.00 of incremental asset value for every $1.00 invested in energy performance improvements.
ENERGY STAR Financial Case
ENERGY STAR Market Barriers
• Lack of Corporate Commitment
• Lack of Information
• Lack of Measurement Tools
• Tenant/Landlord Split Incentives
ENERGY STAR Program
• By encouraging top-level commitment.
• By creating easily accessible online information.
• By establishing a standardized energy performance rating system.
• By promoting system integrated approach to upgrade buildings.
How to attain an ENERGY STAR Label for a Commercial Building
• A Professional Engineer (PE) must perform the 3rd party validation of the building
Gather UtilityData
Verify, IAQ thermal comfort, illumination levels
Meet ENERGY STAR criteria ?

2. Gather Utility Data
• Eleven (11) months of consecutive utility data
• EPA Portfolio Manager rating of 75 or greater for ENERGY STAR Label
• EPA Portfolio Manager rating of 60 is prerequisite for LEED EB certification in Energy and Atmosphere category.
3. Verify IAQ, Thermal Comfort, and Illumination Levels for Building
A Professional Engineer (PE) is required to perform a site assessment to determine if building complies by:
• ASHRAE 55 – Thermal Comfort Criteria
• ASHRAE 62 – Outdoor Air Ventilation, Indoor Air Quality
• IESNA – Illumination Criteria
4. Submit Documentation for Energy Star Award
• PE Signs a Statement of Energy Performance and submits the document to the EPA for evaluation and ENERGY STAR award label.
Case Study – Capital Circle Office Center (CCOC), Department of Management Services, Tallahassee, Florida
• Fifteen (15) High Performance Buildings
• 1,225,704 square feet
• Designed for efficient operation, low maintenance costs, flexible floor plans, extended life cycle
Capital Circle Office Center (CCOC), Department of Management Services, Tallahassee, Florida
High Performance Features
• Central energy plant on densely developed campus
• Low-e glass• Sealed thermal envelope• Light sensors in office areas• Mandates for ENERGY STAR
equipment• Variable air volume HVAC
equipment• Digital Controls for faster
reliable adjustments as well as operating use
CCOC Energy Star Study Data Collection
• Several buildings were eliminated due to either poor performance or inaccurate data output.
• Only four (4) buildings yielded consistent chilled water and electrical consumption readings.

Site Assessment for Two (2) ENERGY STAR Eligible Candidates
• Temperature, humidity, illumination readings and volumetric airflow measurements were performed for office spaces, air handlers, and exhaust fans.
• One building did not satisfy the ASHRAE ventilation criteria.
Building Performance for Energy Star Award Winner
Relative to a similar building type and square footage with an Energy Star rating of 23
