​An introduction to the processes by which construction materials and systems are evaluated, selected, incorporated, and detailed in building design. Both measurable and immeasurable design responses to environmental energies are explored in soils, concrete, masonry, and metals. In addition, concrete construction will be studied in some detail because of its predominance in our building culture. This emphasis on· a single system will establish a foundation for further study of larger scale systems in subsequent courses. Issues of sustainability in building system design and construction process will be engaged throughout.
