A method for determining heat and/or energy loss from a building using a thermographic image of the building, the image of the building being captured at a pre-determined angle, preferably perpendicular to the building, the method comprising analyzing automatically the image to determine the temperature of areas of the image, determining the real size of the scene associated with the image areas that are above a pre-determined temperature and using this to determine heat and/or energy loss from the building.
