Building
A building, or edifice, is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, and aesthetic reasons.

Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.
Building
I knew, as everyone knows, that the easiest way to attract a crowd is to let it be known that at a given time and a given place some one is going to attempt something that in the event of failure will mean sudden death. That's what attracts us to the man who paints the flagstaff on the tall building, or to the 'human fly' who scales the walls of the same building.
