  4. 4. Sustainable Danville Area’s Top Ten
  5. 5. Eliminate Phantom Energy Watt meters: helpful in gauging the „phantom‟ or „vampire‟ power used by electronics in standby mode  Kill-A-Watt ($25) & WattsUp ($96)  Consumer Reports has confirmed readouts on these meters matched those from a calibrated watt meter in their labs.  Kill-A-Watt – Available for loan from the CC Library System Smart Strips ($29): power strip automatically switches devices on/off when not in use to save energy PG&E‟s SmartMeters: track real-time energy use online  PG&E offers free Energy Efficiency Workshops to all customers. Lots of topics, schedule available at www.pge.comSustainable Danville Area – January 2011: Save Energy
  6. 6. Water – Every Last Drop Counts Mindful water use  Fix leaky faucets and toilets  Remember to turn off faucet when brushing your teeth  Time your showers or beat stress, take a bath  Use cold water and only wash full loads laundry  Run the dishwasher only when full  Use a broom to clean driveways and sidewalks  Water your lawn only when it needs it  Adjust sprinklers so they don‟t water driveways and sidewalks Plant California-friendly trees and plants Consider grey water systems to collect shower and laundry water for landscaping useSustainable Danville Area – January 2011: Save Energy
  7. 7. Water – Every Last Drop Counts Maintain your water heater, consider replacing with energy efficient model  Choose energy efficient on-demand or solar units (30% tax credit until 2016) Consider alternatives to running hot water when washing dishes  Soap all pots/pans, dishes before rinsing  Use a basin full of hot water verses running water  Install a pedal valve to control sink water (kitchen or bathroom)Sustainable Danville Area – January 2011: Save Energy
  8. 8. Landscape for shade and windbreak Plant for Summer Shade  Trees planted on the south-west side of house can cut air conditioning costs an estimated 30% compared to an un-shaded house  Trees, shrubs, ground covers and grass affect solar radiation more than structural devices, such as awnings by absorbing sun‟s heat while transpiring (release water vapor from leaves) cooling moisture into the air Temperature under a tree can be 9ºF lower than an adjacent area - and up to 25ºF lower than air near a blacktop surface street Plant for Winter Windbreak  Barriers to reduce & redirect cold winds and protect area from blowing dust, rain and soil erosion.  Generally a single or multiple row of trees, shrubs, perennial crops, tall grasses or fencing  Can reduce wind by 50% and winter heating by up to 25%Sustainable Danville Area – January 2011: Save Energy
  9. 9. Purchase Energy Star Appliances ENERGY STAR® is a voluntary labeling program designed by the U.S. government to identify and promote energy-efficient products:  Reduce greenhouse gas emissions and other pollutants caused by inefficient use of energy  Make it easy for consumers to source energy-efficient products… save money on energy bills without sacrificing performance, features and comfort. • Refrigerator • Water Heaters & Coolers • Audio/Video • Freezer • Air Cleaners & Purifiers • Battery Chargers • Dishwasher • Dehumidifiers • Computers • Washer/Dryer • Air Conditioners • Cordless Phones • Microwave • Furnaces • Displays/Televisions • Ranges & Ovens • Boilers • Light Bulbs & Fixtures • Heat Pumps www.energystar.govSustainable Danville Area – January 2011: Save Energy
  10. 10. Purchase Energy Star AppliancesAmerican homes consume six timesthe energy of the world average. • Replacing old appliances is one of the most important things people can do to reduce GHG. • Front-loading washing machines are much more energy efficient than top-loading models • ENERGY STAR refrigerators use 40% less energy today than models did in 2001.Tax Credits –30% of the cost in 2009 & 2010 (<$1,500 total) forenergy-efficient improvements to existing homes fornew windows, doors, insulation, roofs, HVAC systemsand water heaters.30% of the cost (no max) until 2016 for solar panels,geothermal heat pumps, solar water heatersSustainable Danville Area – January 2011: Save Energy
  11. 11. Lights, Please “Low-hanging fruit” for reducing energy consumption. Lighting accounts for 22% of all electricity consumed nationwide One-fifth of all energy used by commercial buildings is consumed by lighting Lighting has evolved in response to unprecedented amount of new laws focused on energy efficiency & environmental protection: Light … Energy Efficient Light … Environmentally Conscious Energy Efficient LightSustainable Danville Area – January 2011: Save Energy
  12. 12. Three main technologies available today:  Incandescent: warm dimmable light but fragile filaments and glass, lasts about 1000 hours, only converts 10% of energy used to produce light – so 90% is wasted as heat  Fluorescent: more energy efficient but wastes 30% of energy as heat, ballasts consume energy when fixtures “off”, unpleasing buzz, delays & color, poor „dimmability‟, unpredictable life, relies on igniting mercury vapor within fragile glass… hazardous materials cannot go into garbage (but they do because lack of messaging & services)Sustainable Danville Area – January 2011: Save Energy
  13. 13.  LED (light emitting diode): digital device that emits light, fits existing fixtures, exceptional color & quality, requires highly engineered thermal management to ensure longevity & performance. Typically 50,000 to 60,000 hours (50 times longer life) More Energy Efficient – saves up to 80% Recyclable, no mercury or lead or fragile glass Smooth phased „dimmability‟ & full brightness without delays High Cycling Capacity – never loses life with frequent on/off‟s Directional, Versatile & Scalable – light goes where it is neededSustainable Danville Area – January 2011: Save Energy
  14. 14. Lights, Please Wild-Wild-West of LED Lighting – Buyer Beware • Very crowded, unregulated product category today • Lots of products being rushed to market… unreliable, poor light quality • Causing consumers to lose confidence in the technology LED lighting is not hype, just not ready for retail market yet • Commercial-grade products delivering outstanding performance & ROIs • Large buildings able to capitalize most on the energy savings today (volume) • Once demand by facilities drives production up, pricing will fall to make advanced features and quality products cost effective for general consumers (within next 2 years)Sustainable Danville Area – January 2011: Save Energy
  15. 15. Paradigm Shifts in Lighting• Refer to light output rather than watts to describe the intensity of a bulb• Integrated system (like heating & cooling); phasing out bulb + fixture• “Cost of ownership” vs. initial cost• Hopefully leading away from “product obsolescence”• Collective buying programs within school districts, HOAs, Chambers of Commerce to help residents & small businesses benefit from reliable LED products todaySustainable Danville Area – January 2011: Save Energy
  16. 16. Stricter building codesraising energy efficiencystandards for residential &nonresidential buildings,with specific requirementsfor lighting (i.e. CA Title 24)Energy Independence &Security Act of 2007:requires general-purposelight bulbs that produce 310–2600 lumens of light be 30%more energy efficient by 2012to 2014. Starting with 100-watt bulbs in January 2012and end with 40-watt bulbs inJanuary 2014.Point-based green buildingprograms: LEED, HERS,HOME STAR®, CHPSSustainable Danville Area – January 2011: Save Energy
  17. 17. Program your thermostat Using a programmable thermostat in your home is one of the easiest ways to save energy, money and help fight global warming. • Average household spends more than $2,200/year on energy bills - nearly half goes to heating & cooling. • Homeowners can save about $180/year by properly setting programmable thermostats & maintaining those settings.Sustainable Danville Area – January 2011: Save Energy
  18. 18. Program your thermostatSustainable Danville Area – January 2011: Save Energy
  19. 19. You can achieve significant savings by sticking with these default settings (intended to deliver savings without sacrificing comfort)… SETPOINT TEMPERATURE PROGRAM TIME (HEATING) (COOLING) Wake 6 AM ≤ 70º F ≥ 78º F Day 8 AM Setback at least 8º F Setup at least 7º F Evening 6 PM ≤ 70º F ≥ 78º F Sleep 10 PM Setback at least 8º F Setup at least 7º F … or adjust them as appropriate for your household. But keep in mind the number one failure of these devices is manual overridesSustainable Danville Area – January 2011: Save Energy
  20. 20. Getting the most out of your programmable thermostat• Keep temp set at energy savings set-points for long periods (at least 8 hours)• You use more energy (and spend more money) by consistently overriding the pre-programmed settings; overrides are cancelled automatically at next program start.• Units have permanent/vacation & temporary hold features. Avoid permanent hold feature to manage day-to-day temperature settings. Youll waste energy & money if “hold” is at a comfort setting while youre away.• Cranking your unit up to 90º or down to 40º will not heat or cool your house any faster. Most thermostats begin to heat or cool at set time, to reach set point temperatures sometime thereafter. (Adaptive recovery units constantly calculate amount of time required to heat or cool house.)• Multiple HVAC zones? Customize programming to maximize comfort, convenience & energy savings throughout house.• Don‟t forget to change batteries if your thermostat is not hard-wired.Sustainable Danville Area – January 2011: Save Energy
  21. 21. Heat and Cool EfficientlyMaintain your equipment  Change your filter at least two times per year – 4 times per year is best  Consider using electrostatic filters which last 12-15 years  Need to be washed every two months  Rated Allergy Gold  “Whistling could be an issue  Have a Professional tune up your HVAC system each Spring and FallSustainable Danville Area – January 2011: Save Energy
  22. 22. Heat and Cool Efficiently Ducts that move air from forced heating/cooling systems are often energy wasters – typically up to 20% can be lost to leaks Seal air leaks using mastic sealant or metal tape – do not use duct tape Make sure connections at vents and registers are sealed where they meet floors, walls and ceiling – common locations for leaksSustainable Danville Area – January 2011: Save Energy
  23. 23. Heat and Cool Efficiently Energy Star recommends considering a change to your system if:  Some rooms are too hot or cold, have humidity problems or excessive dust.  Your equipment needs frequent repairs and your energy bills are going up.  Your heating and cooling equipment is more than 10 years old. Age & condition of your heating and cooling equipment may have caused it to become less efficient. Consider replacing it with newer, more efficient equipment.  You used EPA‟s ENERGY STAR Home Energy Yardstick (www.energystar.gov/yardstick) and your score is below 5 – which means you‟re paying for more energy than most Americans.Sustainable Danville Area – January 2011: Save Energy
  24. 24. Heat and Cool Efficiently Purchase ENERGY STAR qualified gas furnaces:  have annual fuel utilization efficiency (AFUE) ratings of 85% and 90% - or greater, making them up to 15% more efficient than standard models.  have highly efficient blower motors. Purchase ENERGY STAR qualified central air conditioners:  have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings, making them about 14% more efficient than standard models.  The only way to ensure that your new air conditioner performs at its rated efficiency is to replace your heating system at the same time. It‟s especially recommended if your furnace is over 15 years old.Sustainable Danville Area – January 2011: Save Energy
  25. 25. Insulate Insulation Energy Loss Areas of Concern:  55% Attic  35% Exterior Walls  5% Outlets and around windows  5% Subfloor with crawl space To get the biggest savings, the easiest place to add insulation is the attic. Type of Insulation to use:  Fiberglass, recycled glass, is the safest and most cost effective way to insulate your home. 40% produced in US with remaining usually from Canada  Cellulose (70% recycled newspaper) contains fire-retardant/control for vermin and mold chemicals  Blue jean material is heavy & and hard to fit properly around pipes and electrical (hard to cut).Sustainable Danville Area – January 2011: Save Energy
  26. 26. Insulate To get the biggest savings, the easiest place to add insulation is the attic.  Recommended levels of insulation for your attic  Existing 3-4 inches of insulation: R25 - R38  Floor: R19 – R25 If you are removing siding from a wood-frame wall without insulation:  Add R5 insulation wall sheathing beneath new sidingSustainable Danville Area – January 2011: Save Energy
  27. 27. Seal the air  Seal the "envelope“ of your home - outer walls, ceiling, windows, doors, and floors  Many drafts are easy to feel – leaky windows & doors. Seal with caulk, spray foam, or weather stripping  Holes hidden in attics, basements, & crawlspaces are usually bigger energy problems.  Fireplaces without doors are one of the biggest heat loss & cold gain areas in your home. Add doors!  After any home sealing project, have a heating & cooling technician check to make sure that your combustion appliances (furnace, water heater, and dryer) are venting properly.Sustainable Danville Area – January 2011: Save Energy
