The average single-family home built today is 2,657 square feet, more than twice the average single-family home built in 1920. To determine how homes have changed over the past century, 24/7 Wall St. estimated the size of a newly constructed single-family house between 1920 and 2014.
To estimate the energy savings it is reasonable to assume that the average length to the fixtures in the house is half the trunk length plus the length of the branch to the fixtures. The 1-story house has an average length of 67 feet; the 2-story house and the apartment have an average length of 31 feet.For simplicity we will use a range of 30-60 feet. The average volume in the 1-story house is about 1.5 gallons; the average volume in the 2-story house and the apartment is about 0.6 gallons.o estimate the energy savings it is reasonable to assume that the average length to the fixtures in the house is half the trunk length plus the length of the branch to the fixtures.
