ABET The recognized accreditor for college and university programs in applied science, computing, engineering, and technology. Aesthetics The quality of an object that deals with art, beauty, and taste. Allowable Strength Nominal strength divided by the safety factor. AIA The American Institute of Architects (AIA) is the professional society representing the field of architecture and others working in the architecture field. Air Handling Unit A device used to condition and circulate air as part of a heating, (AHU) ventilating, and air-conditioning ( HVAC ) system. Arch A curved structure for spanning an opening, designed to support a vertical load primarily by axial compression. Architect An individual trained in the art and science of designing and constructing buildings. Architectural Research and decision making process that identifies the scope Programming of work for a design project. Architectural Written statement setting forth design objectives, constraints, Program and criteria for a project, including special requirements and systems, and site requirements. The program is usually prepared by the architect with input from the owner regarding the goals, needs, and function of the project, design expectations, available budget, and pertinent building code and zoning regulations. ASCE The American Society of Civil Engineers (ASCE) is the professional engineering society representing the field of civil engineering and others working in the civil engineering field. ASD Allowable Strength Design. A method of designing structural elements such that the allowable strength is greater than or equal to the strength necessary to support the required load combinations. Axial Force A force that acts along the longitudinal axis of a structural member. Axial tension causes elongation of the member. Axial compression causes shortening of the member.

Balance The pleasing or harmonious arrangement or proportion of parts or elements in a design or composition. Ballast A heavy material installed over a roof membrane to prevent wind uplift and shield the membrane from sunlight. Baseline A parallel of latitude running through an arbitrary point chosen as the starting point for all sectionalized land within a given area. Beam A structural member, usually horizontal, that carries a load that is applied transverse to its length. The use of physical laws and mathematics to compute internal Beam Analysis forces, stresses, and deformations. Bearing A horizontal direction indicated by an angle from either due north or due south toward either the east or west. Bearing Walls Solid walls that provide support for each other and for the roof of a structure. Berm A horizontal ledge cut between the foot and top of an embankment to stabilize the slope by intercepting sliding earth. Brownfield Real property of which the expansion, redevelopment, or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Building Code Legal requirements designed to protect the public by providing guidelines for structural, electrical, plumbing, and mechanical areas of a structure. Building Envelope The portion of a building that encloses the treated environment, including the walls, ceiling or roof, and floor. Built-up Roof (BUR) A roof membrane laminated from layers of asphalt-saturated felt or other fabric, bonded together with bitumen or pitch.
