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.

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.
