Marker Time – Energy Efficiency (Utility Costs)

Today’s Marker Time is the first in a series of videos that will look at the Energy Efficiency of the 100K House project. The first in this series looks at the utility costs of the 120K House versus that of a similar new construction house built to code and an existing house that is not new. This video is a bit heavy on the numbers and was filmed late in the day when my enthusiasm levels were a bit drained, but hopefully our points come across fairly clearly.

Marker Time – Energy Efficiency (Utility Costs)

Here is a recap on some of the numbers covered in the video:

Second Radiant Heating System Quote
  • The 120K House uses half the energy of a standard code built home
  • An existing (non new construction) home uses 2.5 times more energy than the 120K House
  • A code home will cost an extra $1,037/year or $86/mo compared to the 120K House
  • The extra utility cost of the code home raises the actual cost of a $250K purchase price to $263K
  • An existing home will cost an extra $2,034/year or $170/mo compared to the 120K House
  • The extra utility cost of the code home raises the actual cost of a $250K purchase price to $276K
  • If you applied the extra $170/mo to the mortgage on the 120K House that you would be saving in utility costs
