r value question

BigErl Member Posts: 29
I am attempting to do a heatloss calculation on a brick row house 15 feet wide by 37 feet long.  There is a similar attached row house on both sides along the 37 foot wall.  Since there is a heated home on either side what type of R value should I assign to these walls?

    row houses

    Are the two houses on either side heated?  If so, you can usually disregard losses through those walls.

    Thanks SWEI. Yeah both houses have heat in them.
