Slide 7: Boiler Burner Controls
Boiler Burner Controls • Boilers waste energy during start-up cycle – the more cycles the more waste • M2G Boiler Controller by Greffen Systems (US) Reduces boiler cycles and saves energy www.greffensys.com YourEnergySavings.com
Slide 8: Boiler Controls
Boiler Controls • O2 Trim • Boiler Aquastat Reset Control YourEnergySavings.com
Slide 9: Space Cooling
Space Cooling • Comfort • Operating Cost • Indoor Air Quality YourEnergySavings.com
Slide 10: Space Cooling - Dehumidification
Space Cooling - Dehumidification • Desiccant Dehumidification – Removes humidity without cooling the air – No ‘cold-clammy’ feeling from air that is over-cooled yet still too humid • Energy Recovery – Ventilation Air – Works in heating and cooling mode to supply fresh air without loosing heat/cool/h
Slide 11: Space Cooling - Dehumidification
Space Cooling - Dehumidification • New smaller sizes • More focus on energy recovery www.novelaire.com YourEnergySavings.com
Slide 12: Space Cooling - Dehumidification
Space Cooling - Dehumidification • Reactivation heat source can be gas, electric, or waste heat • Energy recovery units may not require reactivation air heat source in all modes of operation YourEnergySavings.com
Slide 13: Ventilation – CO2 Demand Control
Ventilation – CO2 Demand Control • Ventilation air is expensive – both heating and cooling • Poor indoor air quality can be MORE expensive • CO2 Demand Control assures the right amount of fresh air under all occupancy conditions YourEnergySavings.com
Slide 14: Waste Heat Recovery
Waste Heat Recovery • Air, water, or product/process • Higher the temperature and the longer the run hours the better the economics • Must have a concurrent need for cold incoming supply at the same time in relative amounts as the hot exiting supply YourEnergySavings.com
Slide 15: Waste Heat Recovery – Air to Air
Waste Heat Recovery – Air to Air • Clean waste air stream such as from central ventilation system • Works in heating and cooling modes; with and without humidity recovery www.semcoinc.com YourEnergySavings.com
Slide 16: Waste Heat Recovery – Air to Air
Waste Heat Recovery – Air to Air • Air to Air Heat Recovery with unique design for high-efficiency especially in cold weather www.tempeffnorthamerica.com • Michigan representation: www.thermalnetics.com YourEnergySavings.com
Slide 17: Waste Heat Recovery – Electric Generation
Waste Heat Recovery – Electric Generation • Waste water stream of about 200 gpm up to 200F (or clean air stream equivalent with additional heat exchanger) • Produce up to 50 kWh (depends on waste stream flow) www.prorenewables.com (Michigan Representation) www.electratherm.com (Manufacturer) YourEne
Slide 18: Food Service Equipment
Food Service Equipment • Cooking Equipment • Kitchen Ventilation Equipment • Booster Water Heating • Dishwashing Spray Nozzles YourEnergySavings.com

Slide 25: Water Heating Systems
Water Heating Systems • Tankless • High-efficiency tank-style • Consider: – Capacity – Schedule • Look for efficiencies >80% YourEnergySavings.com
Slide 26: Water Heating Systems
Water Heating Systems • Direct Contact water heaters are used in VERY high volume applications – laundry, food processing, etc. • Most are now approved for direct food contact • Efficiencies can exceed 100% at low operating temperatures (combustion process makes hot water in addition to supplied col
Slide 27: On-Site Power Generation
On-Site Power Generation • Technologies include: – Micro-Turbines – Engine-Driven – Fuel Cells • With Michigan energy rates, MUST have simultaneous demand for electric and hot water For detailed info see: www.PowerOnsite.org YourEnergySavings.com
Slide 28: Add Natural Gas to EXISTING Diesel Standby Gensets
Add Natural Gas to EXISTING Diesel Standby Gensets • Burn up to 70% natural gas in diesel gensets • Greatly increase run time with on-site fuel storage • Reduce running cost • Improve emissions • Fast payback with normal run time www.gti-altronicinc.com YourEnergySavings.com
Slide 29: Natural Gas Vehicles = NGV Compressed Natural Gas = CNG
Natural Gas Vehicles = NGV Compressed Natural Gas = CNG • Benefits of NGV’s: • Economics • Environmental • Energy Security • Target vehicles: • Pick-ups, • Vans, • Busses / Shuttles, • Heavy duty trucks with predictable routes or areas • Target locations – Existing public “fast-fill” fueling station
Slide 30: What is the Customer Value Proposition?
What is the Customer Value Proposition? NGVs produce approximately 25%-30% less CO2 as compared to their gasoline / diesel Environmental counterparts. 70-90% reduction in all other vehicle emissions. 86% of the natural gas consumed in the U.S. is domestically produced – 98% if you include Energy Sec
