The Thermal Performance Energy of the building

Wood-frame construction practices used in North America today have evolved over a long period of time in all country of word . Changes have been driven by the availability of materials; development of new building materials; population growth (the need for more multi-unit buildings); and pressures to use labour, materials, and energy more efficiently. While this evolution has accelerated rapidly in the last 30 years, the fundamental wood-frame structural system has remained unchanged for much longer.
