Planning Your Half Program


Doing your own half plan l.jpg
Doing Your Own “Half” Plan

Making a “Half” Plan

  • Make a BIG list of project ideas

  • Estimate energy and CO2 savings for each project

  • Prioritize Projects

  • Make it Happen!


Doing your own half plan46 l.jpg
Doing Your Own “Half” Plan

1) Make a BIG list of ideas

  • Consider anything

    • Include all of your energy uses

    • Include conservation, solar, …

  • Sources of ideas

    • Attached resources list


Sources of project ideas l.jpg
Sources of Project Ideas

Some good sources for ideas:

  • Build It Solar www.BuildItSolarMy site -- Look at the Projects page and the Half Plan pages.

  • Utility audit program – these can be quite good, and some even include blower door tests to check your house for infiltration.

  • Rocky Mountain Institute www.rmi.orgThe “Energy Briefs” papers are very good.

  • Energy Star www.energystar.gov/Lots of good information on Energy Star rated appliances as well as a wide variety of other energy efficiency subjects.

  • ”The Carbon Buster’s Home Energy Handbook”, Stoyke, 2007

  • The EERE site www.EERE.Energy.gov/Consumer

  • Home Power Magazine, Mother Earth Magazine, …

2) Evaluate each project for how effective it will be in reducing energy, CO2 emissions, and cost.

  • This is the key to getting the best results for the money you have to spend

  • Projects rates of return will vary over a very large range – this step helps you pick the good ones.


Tools to evaluate projects l.jpg
Tools To Evaluate Projects

  • Insulation Upgrade Calculatorwww.builditsolar.com/References/Calculators/InsulUpgrd/InsulUpgrade.htmThis simple calculator can be used to evaluate insulation upgrades, window improvements, storm windows.

  • The “Half Plan” Exampleshttp://www.builditsolar.com/References/Half/Projects.htmThese example projects each include details the details on how the energy saving was calculated.

  • “The Carbon Buster’s Home Energy Handbook”, Godo Stoyke, 2007Many concrete examples of energy reduction projects.

  • Carbon emissions calculator --Infinite Power http://www.infinitepower.org/calculators.htm

  • Car Carbon emissions -- Hybrid Cars dot Com http://www.hybridcars.com/calculator/

  • If you get stuck – contact [email protected] do my best to help or find someone who can.

3) Prioritize -- Decide what order to do projects in

  • Cheapest and best payoff first

  • Some may need to go earlier

  • The most interesting ones

4) Do the projects

The fun part!

Keep track of your bills for rebates and tax credits


Can it make a difference l.jpg
Can it make a difference?

If 100 million families each reduced greenhouse gas emissions by 20 tons, it would reduce total US green house gas emissions by 25%
