18 IMPROVEMENT ANALYSIS REPORT Jack and Laura Stone Page 4 Existing: Proposed: 1. Units As Spec. Measure: Performance End Group Criteria Ranking Criteria: SIR Cutoff: Maximum $ Limit: No Limit Measures: Non-Interactive The home's energy efficiency is rated using the HERS Index as defined in the RESNET "Mortgage Industry National Home Energy Rating Systems Accreditation Standards," 26. An Index of 1 represents a home that meets current energy codes. A lower Index indicates the home uses less energy than a code home, a higher Index indicates the home uses more energy than a code home. The rating considers all energy use in the home. The rating should be used only for comparison, since it assumes average climate and thermostat settings, quantities of hot water, and internal loads for a typical household. Energy costs are based on local energy prices at the time of rating. If energy efficiency improvements are made to the home, or energy prices change significantly, the rating and annual energy costs may change. Although every effort has been made to provide accurate information, this rating does not constitute a warranty, expressed or implied, about the energy efficiency or operating costs of the house. Estimated savings for each improvemen are calculated assuming accordance with all local codes and standards, and that no other improvements are implemented. The cost estimates for improvements are established by the local HERS provider.

19 Home Energy Retro-Fit Jack and Laura Stone 17 S Ocotillo Dr Apache Junction, AZ 8512 by: Kirsten Shaw Advanced Energy Efficiency October 24, 213 REM/Rate - Residential Energy Analysis and Rating Software v Architectural Energy Corporation, Boulder, Colorado.

20 Home Energy Retro-Fit The Home Energy Retro-Fit report lists changes, or retrofits, that you can make to your home to save energy and money. Acting on the energy retrofit recommendations will make your home more comfortable, more valuable, and more affordable. Advanced Energy Efficiency recommends these retrofits, based on data gathered in a detailed inspection of your home. If you desire more detail on the retrofits or the cost estimates, contact Advanced Energy Efficiency, which provided you this service. Energy Retro-Fit Table The Energy Retro-Fit table shows a package of energy retrofits for you to consider. The energy savings associated with each retrofit does not consider interactions with other retrofits in the table. This means when considered as a package, individual energy savings will most likely decrease due to interactive effects. You can see how good of a financial choice these measures are by looking at the last column.

22 Energy Costs by End-Use The Energy Costs table compares the "before" and "after" annual energy costs to show energy cost savings. It groups retrofits by "end-uses," which are broad categories of how energy is used (or generated) in a home. Note that Photovoltaic panels (PV) generate energy, so as a result this "end-use" shows negative costs, if present. The Total Costs bar chart gives a visual sense of how the annual operating costs of your house could change by incorporating all the listed energy retrofits. The HERS Index bar chart provides a snapshot of your home s energy efficiency before and after retrofits. The HERS Index shows the energy efficiency rating of your home, similar to the way a miles per gallon rating shows the efficiency for a car. Energy Costs ($/year) Total Costs ($/year) HERS Index End-Use As Is With All Improvements Savings Heating Cooling Hot Water Lights and Appliances Photovoltaics - - Service Charge TOTAL As Is Improved The bar chart below displays the annual energy cost savings ($ per year) associated with the energy retrofits you choose. Some retrofits interact with one another, and the total savings offered by each can change if the package of combined retrofits changes. For example, if you increase the insulation of your home, the energy savings you can gain from installing a more efficient furnace will be less than if you only install the furnace. However, the total savings will be greater if you choose both retrofits.
