WebApr 11, 2024 · 5. Radiant Barrier Insulation Radiant barrier insulation is similar to reflective insulation, and it uses aluminum foil to reduce the transfer of radiant heat energy. Radiant and reflective insulation is more effective in hot climates as it can significantly reduce heat gained by the metal building. 6. WebJan 30, 2024 · Energy is measured in terms of its ability to perform work or to transfer heat. Mechanical work is done when a force f displaces an object by a distance d: (1) w = f × d. The basic unit of energy is the joule. One joule is the amount of work done when a force of 1 newton acts over a distance of 1 m; thus 1 J = 1 N-m.
