1 Home Energy Workshop Mark Porth & Bob Schultheis June 20 th, 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! "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! 3 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 5 1

2 Conservation saves energy saves $$$ Home Energy Consumption 7 8 Consumption 3 factors 1. Climate and Home Site 2. Structure/Building Envelope 3. Occupant Habits and Behavior A house energy audit guides weatherization priorities! 9 10 Climate and Building Site Temperature Precipitation Wind Solar Orientation of home Topography of site Vegetation on 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 2

3 Occupant Habits and Behavior Temperature settings Energy ethic and behavior Appliance selection and use Heating/AC system maintenance Hot water usage Building envelope maintenance 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 Priority weatherization measures An audit consists of 5 assessments: Building envelope evaluation Building insulation and air tightness Mechanical system assessment Electric base load assessment Occupant behavior assessment Energy Audit Blower Door Duct Blaster Inspection Energy Audit Duct Blaster Energy Audit Thermal Imaging Blower Door Inspection

4 Home Energy Checklist Helps you evaluate: Insulation Holes in the structure Windows Doors Heating/Cooling systems Water heaters Appliances 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? Lighting Low Cost/No Cost

5 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 Ways to Control Phantom Drains Unplug it! Use a Power Strip/Surge Protector Conventional Switched Automatic Energy Star rated devices All weatherization measures can be applied to mobile homes. Simple Low cost No special tools Anyone can do them Potential for a large payback! Programmable Thermostat Set back 1 for 8 hours/day = 1% Energy savings Cost $30 50 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 = $

6 Replace Dryer Vent Shuttle design can reduce heat loss by 80% Cost $20.00 Payback approx 1 year depending on location Change the furnace/ac filters Can reduce efficiency by 20+% Cost about $1.00 Payback less than 2 days Receptacle and switch gaskets Can reduce drafts Cost about $0.30 each Payback depends on the wall! 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! 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! 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 $ Payback 1 season

7 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! 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 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 Electrical flow interrupter device Resources
