Calculating heat loses.

(OP)
i am having a hard time calculating the heat loses for a building.

Building 18' x 18'Plain concrete block on a concrete slab (4" assuming). (Footer will be larger.) No windows. a 36 sf steel door. All vents equal a 46 sf. the roof is asphalt shinged hip style roof, 10' walls. Temp In = 65 F and Temp out = -5 F.

Can anyone help point me in the right direction? I have a book with Qt = Qtr + Qinf + Qvent. I have worked with this clculation but am not confident with answers.
