that about 30 percent of the sampled homes have responded to the promotion of a 68 degree day time thermostat setting. This drops to about 28 percent during the evening hours and then jumps to 57 percent at night. Another frequency distribution by age of home is shown in Figure 1-10 for the presence of storm windows. Inasmuch as the numbers of windows per home varied, the data were grouped to show homes with no storm windows, storm windows on less than and more than half the windows and homes that had all windows equipped with storm windows. It is interesting to note that nearly 90 percent of all homes sampled had over half of their windows equipped with storm windows.

Danbury Profile

A similar series of summary information for Danbury is presented below based on the 616 homes participating in the pilot test.

Ceiling Insulation

Forty-seven percent of the participating homes had an
average of only 3 inches of ceiling insulation.
Increasing this to 6 inches would produce an

average annual heat loss reduction of 364 therms per
home.

Storm Windows

Thirty-six percent of the homes sampled lacked
some number of storm windows. On the average
home this represented between 6 and 7 windows
which, if equipped with storm sash, could yield
an average annual heat loss reduction of 145 therms
per home.

Storm Doors

An average of two doors on 44 percent of the
homes sampled lacked storm doors. The average
annual reduced heat loss that would result from
their installation would be 110 therms per
home.

Weather Stripping/Caulking

Over two-thirds of the participating homes
reported infiltration around doors or

windows. With the installation of appropriate
weather stripping and caulking, these homes
could realize an average annual heat loss
reduction of 96 therms.

• Thermostat Set Back

Only 30 percent of the homes sampled had
thermostat settings over 68 degrees. Although
the average thermostat setting in these homes
was 69.8 degrees, set back to 68 degrees would
reduce their annual heat loss by 87 therms.

These findings are summarized in Table 1-12 along with the estimated fuel savings. The conversion from heat loss to fuel savings assumed heating plant efficiencies of 50% for oil, 60% for gas and 100% for electric. Similar caution to that cited above in the Topeka Profile section is urged when estimating total potential savings for a home.

Employing the data base of housing characteristics as was done for Topeka, a frequency distribution of the existing amount of ceiling insulation by age of home was produced and is shown as Figure 1-11. The profile illustrates that a substantial number of older homes have been equipped with four to six inches of ceiling insulation. The 40 percent of the newer homes likely reflect conservation awareness and the increased construction of electrically heated homes. Over all, however, nearly 75 percent of the homes with unheated, unfinished attics reported less than six inches of ceiling insulation which is nearly identical to the Topeka sample. The frequency distribution of
