<br />Preliminary Results <br /> <br />Water <br /> <br />The results of the mean of differences for the pre-test and post-test period <br />are shown on the tables and graphs on the following pages. Winter water <br />use was evaluated from November through February. The table of water <br />consumption data shows a decrease in water use for the months of <br />November and December with an increase for January and a decrease for <br />February. These four months show evidence of water savings as this is a <br />time when exterior water use is at a minimum. Preliminary results show a <br />savings of 21.09% for these four months. The overall savings for the first <br />year was 12.34%. <br /> <br />Gas <br /> <br />The results of the mean of differences for the pre-test and post-test period <br />are shown on the tables and graphs on the following pages. Gas <br />consumption was evaluated from November through February. The table of <br />gas consumption shows an increase of gas use for November and <br />December, with a decrease for January and February. These four months <br />represent an increase in gas consumption by 13.81 %. The overall savings <br />for the first year was 36.93%. <br /> <br />Electricity <br /> <br />The results of the mean of differences for the pre-test and post-test period <br />are shown on the tables and graph on the following pages. November <br />through February were again the months evaluated. The table of electric <br />consumption shows an increase in electrical use for the months of <br />November, an decrease in use for the months of December, January and <br />February. The four months represent an increase of electrical consumption of <br />1.99%. The overall savings for the first year was 2.93%. <br /> <br />SUMMARY DISCUSSION <br />As in any real life project, this project had many variables to consider. The number <br />of total participants was reduced from 100 to 89. The reduction was primarily due <br />to ownership changes or other situations which were not acceptable for <br />evaluation. The weather was an important variable to consider during analysis. <br />November of 1991 was the coldest November on record. This most likely accounts <br />for the increase in gas and electric consumption. <br /> <br />4 <br />
