This third book in a series of three dealing with building physics and its application, looks to the impact a performance requirements linked approach has on building design and construction. It starts with a resumption of what's expected from buildings, followed by discussing a range of materials needed to guarantee a correct heat, air, moisture response. Then, looked is to preparing the building site, the excavations needed, the foundations, the below-grade parts and spaces, the structural systems commonly used, the floors, different types of outer walls, different types of roof assemblies, inside walls, the glazing, windows, outer doors, glass façades, balconies, all kind of shafts, chimneys, stairs, timber-frame construction, wall, floor and ceiling finishes. Each time again, not only the heat, air, moisture related metrics but also structural integrity, durability, fire safety, acoustics, maintenance, sustainability and buildability are discussed. The whole ends with looking to the risks deficiencies may cause. For this new edition, all chapters have been critically reviewed, actualized and gifted with additional figures where needed, so incorporating the experiences gained from 38 years of teaching to architectural and building engineering students, from 36 years of research, and from 53 years of practice, curing damage cases due to failing performance.
