you need to use the linear expansion coefficient of the material of the building.
let the coefficient be x
let the required temperature be t
then .471=1671*(t-15.5)*x
solve for t from this equation.

You need to know the expansion rate for steel since the steel framework is ultimately what's going to determine the difference. Is the framework exposed to outside temperatures or is it moderated my the controlled climate inside the building?
Oh, one other thing, 15.5C being cold? Ha! Maybe you should try figuring the difference in height of the Sears Tower in Chicago on a 35C summer day and a -25C winter day!
