Home Energy Workshop Mark Porth & Bob Schultheis June 20th, 2015 Bolivar, MO

Energy Management for Home goals … • save energy

• provide comfort • assure safety and health

2

Two Myths to Dispel

• I’ve heard all this before! • Weatherization only applies to wintertime!

3

"I've Heard All This Before!!"

• Many of these - you probably have • However, do you know

– How much do they cost to install? – How hard are they to install? – How you can install these? – How much energy can they save?

• Hopefully learn some new ways to save energy!

“Weatherization Only Applies to Wintertime!”

• Not so fast!!! • Weatherization keeps “CONDITIONED AIR” inside

the house regardless of if it is heated or cooled.

Energy Saving Practices Where does our energy go? Home energy checklist Home energy losses Weatherstripping Insulation Storm Windows

Conservation … - saves energy - saves $$$

Home Energy Consumption

8

A house energy “audit” guides weatherization priorities! 9

1. Climate and Home Site

2. Structure/Building Envelope

3. Occupant Habits and Behavior

3 factors … Consumption

10

• Temperature • Precipitation • Wind • Solar • Orientation of home • Topography of site • Vegetation on site

Climate and Building Site

11

Structure/Building Envelope • Size and design of building • Building materials used • Insulation type and application • Use of vapor & air barriers • Air sealing methods • Type & quality of doors & windows • Fuel and heating system choice • Ventilation • Lighting selection • Appliance choices 12

• Temperature settings • Energy ethic and behavior • Appliance selection and use • Heating/AC system maintenance • Hot water usage • Building envelope maintenance

Occupant Habits and Behavior

13

Home Energy Checklist • Many different ones

available • Allows you to evaluate

your current situation • Can form an energy

savings plan custom fit to your needs

14

Priority weatherization measures …

An audit consists of 5 assessments: • Building envelope evaluation • Building insulation and air tightness • Mechanical system assessment

• Occupant behavior assessment • Electric base-load assessment

Home Energy Checklist • Helps you evaluate: Insulation Holes in the structure Windows Doors Heating/Cooling systems Water heaters Appliances

19

Home Energy Checklist • Use the information to form an

energy savings plan What areas need addressed first? What is the easiest project? What project is the least expensive to do? Which project will have the fastest payback? Which project will have the largest payback?

Low Cost/No Cost

24

Phantom Energy Losses

• Phantom, vampire or drain losses can account for up to 5% of energy expenditures – Anything with a clock – Anything with a remote – Anything that uses a charger – Anything with a converter

25

Ways to Control Phantom Drains

Unplug it! Use a Power Strip/Surge Protector

Conventional Switched Automatic

Energy Star rated devices

26

All weatherization measures can be applied to mobile homes.

27

Five Minute Energy Savers

• Simple • Low cost • No special tools • Anyone can do them • Potential for a large payback!

28

Five Minute Energy Savers

• Programmable Thermostat – Set back 1° for 8 hours/day = 1% Energy savings – Cost -$30-50

29

Programable Thermostat Economics

• Reduce from 70° to 69° from 10 PM to 6 AM – Saves 1% on energy bill – Monthly bill is $200 – saves $2.00 per month

• What if reduced 5° for 8 hours? – Saves 5 % or $10.00 per month – 12 months of the year = $120.00

30

Five Minute Energy Savers • Replace Dryer Vent

– Shuttle design can reduce heat loss by 80% – Cost - $20.00 – Payback – approx 1 year depending on location

31

Five Minute Energy Savers • Change the furnace/ac filters

– Can reduce efficiency by 20+% – Cost – about $1.00 – Payback – less than 2 days

32

Five Minute Energy Savers • Receptacle and switch gaskets

– Can reduce drafts – Cost – about $0.30 each – Payback – depends on the wall!

33

Five Minute Energy Savers • Adjust the refrigerator temperature settings. • Optimum refrigerator range is 37 to 40°F • Optimum freezer range is 0 to 5°F.

– Cost - $0.00 – Payback – Immediate!

34

Five Minute Energy Savers • Clean the lint from the clothes dryer after every

load. Wash it in soap and water every 1-2 months • Save up 1% on your electric bill.

– Cost - $0.00 – Payback – Immediate!

35

Five Minute Energy Savers • Install a whole house fan • Draws cool air into the home through windows • Use in early morning and late evenings • Save up to 5% of total home energy costs

– Cost - $200.00 – Payback – 1 season

36

Five Minute Energy Savers • Use the air-dry setting instead of heat-dry • Cut the dishwasher's energy use 15 to 50%. • Save up to 1% of total home energy costs • If there is no air-dry setting, turn the dishwasher off

after its final rinse and open the door. – Cost - $0.00 – Payback – Immediate!

37

Five Minute Energy Savers • Check your tire pressures

– Can decrease fuel economy by up to 5%! – A low tire has more rolling resistance and takes more

energy to turn – plus you can wear out the tire faster – Cost – $0.00 – Payback - immediate

38

Five Minute Energy Savers

• Replace your auto air filter on a regular basis – Can decrease fuel economy by up to 10%! – Cost - $8-$25.00 – Payback – depends on how much you drive
