Agenda
• Facility Benchmarking• Building Energy Codes• Energy Audits• Energy Efficiency Opportunities• On-site Generation and Energy Storage
Opportunities
Why Energy Efficiency??
• Creates local economic development opportunities• One of the most affordable and immediate ways to
improve – energy self-sufficiency– control energy costs– improve local air quality and public health– limit a community’s carbon emissions and insulate its
exposure to climate impacts
Facility Benchmarking
• Benchmarking the energy performance of your buildings is a key first step to understanding and reducing energy consumption
• Benchmarking drives action and works best when it’s done consistently over time
• Sometimes required for utility rebate and incentive programs or by state or local policies
Energy Codes• International Energy Conservation Code (IECC) • American Society of Heating, Refrigerating and
Air-Conditioning Engineers (ASHRAE)– AHSRAE 90.1
• Adoption and incorporation into building design and construction by local jurisdictions– Title 24, part 6
Energy Codes• Code benefits
– Reduced energy consumption– Building owner cost savings– Reduced CO2 emissions
• Code challenges– Adoption, implementation, compliance, and
enforcement challenges– Lack of training and manpower are roadblocks to
proper enforcement
Energy Audits
• Identify and provide the savings and cost analyses of all practical energy efficiency measures
• May also provide a listing of potential capital-intensive improvements that require more thorough data collection and engineering analysis
Lighting
• Lower wattage fluorescent lamps• Light emitting diodes (LEDs)
– Reduces downtime and labor costs– Reduces cooling requirements
(interior lighting)
• Delamping• Skylights or daylighting
Lighting
• Venue Lighting• Parking lot lighting• Slot machines• Overhead lighting• Hotel room lighting
HVAC Systems
• Higher efficiency equipment– Coefficient of Performance (COP)– Energy Efficiency Ratio (EER)– Annual Fuel Utilization
Efficiency (AFUE)
• Insulating pipes and ducts• Variable Air Volume Systems
Motors and Pumps
• Premium efficiency Motors and Pumps– Fountains, domestic water pumps, pool/spa pumps,
etc.
• Variable Speed Drives
Controls
• Commissioning (Cx)• Retrocommissioning (RCx) and
Monitoring Based Commissioning (MBCx)
• Energy Management Systems (EMS)• Measurement and Verification (M&V)
Controls
• Lighting– Multi-level lighting controls– Automatic daylighting controls– Occupancy sensors– Bi-level lighting in secondary spaces– Demand response controls – Photosensors and automatic scheduling
Controls
• HVAC– Smart thermostats – Economizers– Demand Control Ventilation– Temperature resets (water and air side)– Static pressure reset– Variable speed motors and drives– Control sequence/scheduling optimization
Computers, Appliances and Other Plug Loads
• Vending machine controls• Smart power strips• Power management software• Data Center Optimization
On-Site Generation and Storage
• Combined Heat and Power (CHP)• Solar Thermal
– Central heating systems, Domestic hot water, laundry facilities
• Solar Photovoltaics (PV)• Wind
Leveraging Available Programs
• Local Utility Programs– Rebates, incentives, financing, technical assistance
• State or Federal Programs– DOE CHP Technical Assistance Partnership (TAP)– Self-Generation Incentive Program (CA only)
• Third Party Performance Contracts
