  1. Electric Baseload BasicsACI 09 FUND 8: Wednesday, April 29, 20092:00 pm to 3:40 pm Kansas City, Missouri Rana Belshe Conservation Connection Consulting Fairchild, Wisconsin 715-334-2707 A. Tamasin Sterner Pure Energy Lancaster, Pennsylvania 717-293-8990

  2. Session Objectives Learn how to separate electric baseload from whole house electric use Explore how occupants, equipment, and use patterns affect electricity consumption Evaluate options and actions to reduce use

  3. Today’s Topics The equipment we will talk about today: • Electronics • Lighting • Refrigeration • Water Heating • And a few other things • What they use • How they work • What can be done – in terms of measures and behaviors

  4. Weatherization Core Competencies

  5. Baseload + Seasonal = Total Household Electric Use Baseload: Electricity that power things—lights and appliances--used year round Seasonal use: Electricity used to provide heating, cooling, often dehumidification The goal is to understand how a particular household uses electricity, identify the possibilities for reducing that use and dialogue with the occupant for the best possible outcomes.

  7. Houses don’t use energy. People do.

  8. Reasons to Address Baseload Sometimes, reducing electric baseload can guarantee better savings than measures geared toward reducing the cost of heating and/or cooling: Savings Follows Use. Plug loads are increasing. Electric energy waste (energized equipment not in active use) is increasing.

  9. “ Electricity originates inside clouds. There it forms lightning, which is attracted to the earth by golfers. After entering the ground, the electricity hardens into coal, which, when dug up by power companies and burned in big ovens called “generators,” turns back into electricity, which is sent in the form of “volts” (also known as “watts” or “rpm” for short) through special wires with birds sitting on them to consumers’ homes, where it is transformed by TV sets into commercials for beer, which passes through the consumer and back into the ground, thus completing what is known as a “circuit.” Dave Barry, Funny Times, 2002

  10. Electricity: Energy & Power Energy From meter to utility bill power over time • Watt hour - Wh • kiloWatt hour - kWh (1,000 Wh) Power Nameplate – potential –instantaneous demand • Watt - W • kiloWatt (1,000 W) – kW • Watt - is one joule per second or the power supplied when a current of one ampere is driven by a potential difference of one volt

  11. Energy Cost & ValueFebruary 4, 2009 Cost/Unit x Unit/MBtu = Cost/Mbtu Pricing Source: ww.eia.doe.gov.neic/experts/heatcalc.xls

  12. General Baseload Analysis

  13. Tools of the Trade 2-3 prong adapter MicroWeir or stop watch and container Drip gauge Lamp harp and diffuser extenders Product sheet showing replacement light fixtures Screwdrivers, pliers, or a multipurpose tool like a Leatherman™ Laptop computer with appliance use software • Consumption history • Calculator • Camera • Clipboard & pen • Tape measure • kWh meter • Ground tester • Thermometers • Flashlight • Ladder • Gloves (to remove hot bulbs) • Extension cord

  14. Establish Baseload Use Obtain (a printout of) the customer’s electricity use for at least one year prior to the site visit. Separate the baseload use from the total use by: adding together the three lowest months (not weird numbers) dividing the sum by 3 to get an average baseload month’s use multiplying that number by 12 months This can easily be done visually from a bar chart. There are lots of ways to do this. They all work.

  15. Annual Customer Usage Printout LANCASTERPA17603 LANActive 40256S25894Non Ele Ht Cool 1. Three lowest months = 892+ 1,056+ 1,134 = 3,082 ÷ 3 months 2. Average monthly use = 1,027 kWh/mo 3. 1,027 kWh/mo x 12 mo = 12,328 kWh/yr baseload

  16. Consumption History Approximate monthly baseload use ~ 600 kWh or about 7,200 kWh/year

  17. Annual End Use Consumption Ranges (kWh) National averages trued up to PA utility program experience

  18. Assess the Opportunity for Energy Savings Determine if the customer’s use is in the low, mid range, or high range using their consumption history or data on their utility bills. Focus your efforts in the home based on your determination. Since savings follows use, you will likely find more opportunities to save energy where the use is high. If any category of use is low, then save time and focus where the use is medium or high

  19. Savings Follows Use / Waste Total electricity use relates directly to potential electricity savings

  20. Reasons for High Baseload • Time on – 24/7 adds up quickly • High demand / power (kW) • Poor control strategies • Not known to be operating • Faulty equipment • Intermittent use • Hidden loads • Lots of people in the household PPL Managing CAP Credits Pilot Program, 2006

  26. Power Settings & Mode ON REALLY OFF “OFF” • Standby power • Phantom load • Vampire power • Idle power Anything with a remote, display, touchpad, or light is using power even when turned “off” Active power Low power mode Indeterminate power Sleep/hibernate No power Unplugged Power switched off with strip or other control device

  28. Power Supplies: A Growing Component Function: convert wall voltage ac to low voltage dc needed to operate today’s digital chips, LED indicators, displays, etc. 6% to 10% of U.S. electricity flows through the nation’s 3.6 billion power supplies • Roughly 1 to 2% of U.S. electricity could be saved by improving power supply efficiency • $2.1 to 4.2 billion saved by consumers on their electricity bills • Prevent release of 40 to 80 million tons of CO2 into the atmosphere • Equivalent of taking 2.3 to 4.6 million cars off the road • Equivalent of building roughly 4.5 to 9 average sized power plants 2007 Ecos Consulting, “Final Field Research Report”

  29. Sample Annual kWh of TVs by Mode Standby power is similar regardless of TV type or size. Newer TVs use a lot more energy than older ones. Larger and newer technologies (plasma & rear projection) tend to be used more and are frequently part of a larger entertainment set up. Source: Ecos Consulting, “Final Field Research Report”, 2007

  30. Managing Computer Power Use Teach everyone that it makes sense to Turn off monitor if not using for > 5-20 min. and both CPU and monitor if not using for > 30-60 min. Use power strips for positive “off” and control of peripherals Learn about and teach others about how to Activate Power Management Functions Maximize sleep features in the operating system

  31. Battery Charging Strategies • Chargers can draw 5 to 20 times more power than they can store so... • Unplug chargers once battery is charged • Use timer to control charge cycle • Choose equipment based on charging performance Buy efficient chargers Use rechargeable batteries Use power strips to simplify disconnecting chargers

  33. Strategies to Control Home Electronic Energy Use Unplug stuff you don’t use Manage control settings for maximum efficiency Turn equipment off when not actively using Minimize standby use with power strips, switched outlets, unplugging, etc. Purchase less stuff Buy the most efficient products possible

  34. Nighttime from the Space Shuttle

  35. What Affects Lighting Use? Number of sockets/bulbs Hours of use Wattage Lumens (brightness) Restrictive fixtures / colors Task vs general lighting For each bulb: • Watts x hours = Wh • Wh x .001 = kWh • kWh x $/kWh = Cost

  36. Incandescent vs. CFLs

  37. Lumen Comparison http://www.energystar.gov/index.cfm?c=cfls.pr_cfls

  38. Lighting Lighting can be a surprising share of baseload-- 15-20% Average home has 25 - 43 sockets/bulbs CFLs can typically reduce use electricity use by two-thirds or more Reduced waste heat saves on air conditioning and improves comfort

  39. Choosing Bulbs Look for Energy Star logo Select the best bulb for the fixture Shape Location Color quality Dimmability Highest lumens per Watt Be aware of weight and overheating Mercury content/disposal Lumen equivalency, not Watts Electronic interference

  44. Hard-wired Fixtures http://www.energystar.gov/index.cfm?c=fixtures.pr_light_fixtures

  45. Feedback From the Field Issues: The light is not bright enough The bulb doesn’t fit within fixture The bulb takes too long to brighten The bulb looks weird The bulb was installed without customer acceptance Too few were installed Disposal and mercury concerns So, to assure client satisfaction, choose carefully. There are plenty of excellent CFL’s available.

  46. Baseload and Building Science • One example: • Recessed lights are holes in the envelope, most of which leak air • Local hot spot enhances exfiltration forces • A 13 watt bulb increases air flow through a leaky can by 60% when it’s on, a 50 watt bulb by 170% and a 100 watt bulb by 400%!
