In this reading Ching talks about building performances. He startes off with how buildings need moisture and thermal protection. This varies on the style of the building and the climate of the environment. One method is flashing. Flashing is installed in the walls to collect moisture that goes through the walls. There many types which include head flashing, sill, base course, parapet, and spandrel. When it comes to masonry walls, veneer is used.  Ching then explains thermal insulation. It is to control the flow or transfer of heat through assemblies of a building. He gives a list of thermal resistance for each material and materials that are used for insulation. Each basic structure of a building (concrete, steel, wood) has a way to place the insulation for floors and walls. However, there should be enough room for ventilation. Different types include whole-house ventilation, energy-recovery ventilation, roof and attic, and crawl space.
