A house energy “audit” guides weatherization priorities!
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
Factors that influence consumption
1. Climate and Home Site
2. Structure/Building Envelope
3. Occupant Habits and Behavior
3 categories …
Factors that influence consumption
Climate and Building Site• Temperature• Precipitation• Wind• Solar• Orientation of home• Topography of site• Vegetation on site
Factors that influence consumptionStructure/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
Factors that influence consumption
• Temperature settings• Energy ethic and behavior• Appliance selection and use• Heating/AC system maintenance• Hot water usage• Building envelope maintenance

Heating System - control heating
thermostat- try 68°F.

3Insulate and turn down water heater.
120°F for electric mid or warm for gas
3
Stop hot water leaks and insulate pipes.
4
Close off unused spacesand unplug unnecessaryappliances.
Use tube fluorescent and energy efficient compact fluorescent lights (CFLs) in fixtures throughout your home to provide high-quality and high-efficiency lighting. Fluorescent lamps are much more efficient than incandescent (standard) bulbs and last about 4 to 10 times longer.

Top 5 Tips to Saving Energy at Home
Moderate/High Cost Tips
1
Windows – storm windows(Inside is best)
This option is low cost.
1
Windows – thermal curtains
Heating system tune-up and cleaning.2
Heating system up-grade or replacement.2
2Heating System – Installation of duct mastic & insulation
Insulation –go for easy access
3
The higher the “R” value the greater the “resistance” to energy
flow – the better the insulator.

3
Insulation – type will depend on application
Insulation – rolls and loose fill

3
Insulation – glass fiber R 2.2 – 3.2/inch
3
Insulation – Rock Wool R 2.2 – 3.2/inch
3
Insulation – Polyurethane & PolystyrenesR 4.5 – 6.5/inch
3
Insulation – cellulose fiber - R 3.7/inch
Insulation – vermiculite R 2.2/inch

All weatherization measures can be applied to mobile homes.
1. Estimated energy consumption on a scale showing a range for similar models
2. Estimated yearly operating cost based on the national average cost of electricity.
