There are several ways that you can make a determination. One is the use of an infrared heat meter. On a cold day, using the meter, you stand outside the building and take readings of the infrared radiation given off by various parts of the building. You will most likely find the largest amount of heat loss is through the fenestration.
Another method is to compare energy usage of the building against others of the a similar sq. footage. This method will give you a relative energy efficiency.

Yes; it's your electricity meter. The more energy you consume per square foot of floor space or per cubic foot of air inside the building, the less energy-efficient you are.

First of all, not sure why this question is here...
You have to know what type of insulation, window type, etc that you have, and how many sqft of each.
There are HVAC trade books which have heat transfer coefficients that you multiply by sqft., but you might start below.
