3 Characteristics to an excellent design - {answer}-1. It functions well and serves the needs of its
users
2. it is made of carefull selected quality components and appropriate materials.
3. it is aesthetically pleasing.
Leonardo da Vinci - {answer}-Developed a system of proportions using the human figure with
outstretched arms and spread legs, with arms and legs touching a circle inscribed in a square.
Anthropometry - {answer}-the scientific study of the measurements and proportions of the human
body.
Ergonomics - {answer}-The study of workplace equipment design or how to arrange and design
devices, machines, or work space so that people and things interact safely and most efficiently.
Textures - {answer}-The actual and perceived details on a surface and describe the relative
roughness or smoothness of a surface, the hardness and softness as well.
The Golden Ratio - {answer}-Seemingly magical relationship with the
Fibonacci Series turn out to relate directly to
,natural phenomena such as the clockwise and
anticlockwise spirals on the surface of
pinecones and pineapples and in the centers
of daisies.
Radial balance - {answer}-Is based on a circle with elements arranged
around a single point.
Symmetrical - {answer}-The "Mirror" effect, or when one object is reflected across a plane to create
another instance of itself.
Symmetrical Balance - {answer}-Often associated with formal rooms or traditional interiors. Consider
this when choosing objects for a mantle.
Asymetrical balance - {answer}-distribution achieved by arranging non-identical elements on both
sides of an imaginary center line on the screen. (Associated with contemporary, casual, or country
interiors)
Rhythm - {answer}-involves the repetition of elements in space. Can provide a theme for a room that
the eye enjoys following. (Ex: Stadium Seats can create rhythm and balance)
Emphasis - {answer}-the focal point of a space or object. (Ex. fireplace or large window)
Structural Patterns - {answer}-Those usually created by architectural members or decorative
construction techniques and are three-dimensional.
Applied Pattern - {answer}-Typically a decorative design used on a flat surface and is almost always
based on the repetition of smaller design motifs.
Ornamentation - {answer}-Visual extras added to enrich a design.
Normal Traffic Pattern - {answer}-24"-30", but 36" or more is best.
, Comfortable range of distance for conversation - {answer}-4 and 10 feet
Patterns - {answer}-Create perceived textures.
most used materials for both structural
soundness and interior enhancement - {answer}-1) wood 2) masonry 3) metals 4) glass 5)
plastics 6) other new materials,
sometimes called hybrids
Concrete - {answer}-a wet combination of cement, aggregate and water mixed together.
Cement - {answer}-A dry mix of chalk and clay ground into fine particles then heated until they fuse
together to form ball-shaped particles of cement clinker.
Aggregate - {answer}-materials are gravels and sands used to form the bulk in the concrete mix.
Classified as fine (sand) or coarse (gravel) Ex: Clinker, clay or pumice
Strength of Concrete - {answer}-primarily determined by the ratio of water to cement. The less
water used, the stronger.
Steel - {answer}-Made by removing some of the carbon content of iron. Prone to failure in fire when
temperatures go above 550 degrees Celsius, coated with sprayed concrete or encased in other non-
combustible materials, corrodes in damp conditions, so it is often sprayed or 'hot dipped' with zinc.
Conifer Trees or Softwoods - {answer}-used for rough carpentry or joinery and finished strip and
panel work. (Pine, cedar, redwood, fir, spruce, larch and hemlock).
Deciduous Trees or Hardwoods - {answer}-Dense; chosen for their beauty, quality, and function.
(Oak, Ash, Beech, Birch, Elm, Maple, Poplar, Sycamore, Walnut, Mahogany, rosewood, cherry, and
teak). Used for doors, panels, staircases, fireplaces, ceilings, parquet flooring, and dividing.
Bamboo - {answer}-native to the Far East where it is used structurally and decoratively in buildings
and interiors. Suitable for walls, screens, furniture and flooring. It is often woven into mats, woven
blinds, even cabinet fronts.
