Summary:

Buildings account for 40 percent of the total primary energy consumed in the U.S. Of that primary energy consumed in residential and commercial buildings, space heating and cooling represent approximately 30%. The building envelope plays a key role in determining levels of comfort, natural lighting, ventilation, and how much energy is required to heat and cool a building. Progress in materials science, chemistry, and engineering may lead to dramatic breakthroughs in managing thermal energy and moisture transport in buildings that could significantly reduce the energy required to heat and cool a building and improve occupant comfort.
