Jackie decided to improve the energy efficiency of her home in 2006. Strategies included finding out where the electrical loads were, doing as much of the work ourselves as possible, and replacing inefficient appliances with Energy Star models as resources were available. To date, her projects have included the following:

• Fall 2006: Installed compact fluorescent light bulbs and two programmable thermostats for the two heat pump units. 
                   We also replaced an old refrigerator with an Energy-Star model.

• Spring 2007: The dishwasher was replaced with an energy-efficient Kenmore from Sears.

• Summer 2007:  With a sunny, south-facing roof, this house was a good candidate for solar technology.
                             A solar hot water system was installed in June 2007.
                             The new system has two 4ftx 7ft flat panel collectors tilted at approximately 45 degrees to provide a
                             bias towards winter efficiency.
                            The old 50-gallon hot water heaters were recycled, and replaced with an 80 gallon solar storage tank
                             with an electric backup.

• Fall 2007: A whole house meter was installed to monitor energy use. 
                   In addition, a plug meter was used to test individual appliances. 
                   An inefficient basement humidifier was replaced.

• Winter 2007-2008: A blower-door test was conducted in the house to identify air leaks (house was very leaky).  Air infiltration was found in the recessed lights,
                                 around fireplaces, and around windows and doors.  Caulk and mastic were used where appropriate to seal air leaks.

• Spring 2008: Gila reflective shades were installed on south-facing windows to reflect summer heat. 
                        Thermal imaging was also used at the house to identify areas where insulation was not doing its job.

• Summer 2008: Jackie installed radiant barrier in the attic, and added insulation. The results of the thermal imaging camera were used to improve insulation
                           effectiveness.  A draft-stopping air pillow from Battic Door was installed in the fireplace to eliminate air leaks.

With the exception of one month, the reduction in energy use (and the associated electric bill) has been dramatic.  The following table shows electricity use in kilowatt hours before (from 2003-2006) and after (2007-2008) energy improvements were made.
