select a type of window operation for each situation a) a window that can be let open in the rain b) a window that must induce the max. possible ventilation from breezes c) a window in a high-rise office d) a window to frame an expansive mountain view e) a window that can operate as a casement or hopper
|
a) awning or hopper b) casement c) most inswinging windows d) single/double hung and sliding windows, fixed(prime) windows e) tilt/turn windows
|

|
compare the advantages and disadvantages of wood, plastic-clad wood, PVC, aluminum, and steel as window frame materials
|
WOOD:good insulator, little change with temp changes, not a good with moisture & subject to decay when wetted. CLAD WOOD: most popular for wood frames, more weather resistance and less maintenance. ALUMINUM: strong, easy to form, less vulnerable to moisturre damage, needs thermal breaks for heat flow, more expensive PVC: cheap, never need paint, cheap, good thermal insulators, not strong and have bad thermal expansion. STEEL: very strong, less conductive to heat than aluminum, moderate thermal insulators

|
compare good and bad thermal performance windows with a wall that has a U-value of .05 and an R-value of 20. figure 18.19
|
would be the best in comparison if only single-glazed. would be as bad as aluminum if window was double-glazed with low-e.

|
select a type of door for each situation. a) you bedroom b) a front door of a house c) front door of a department store d) a door opening to the cafeteria in a high school e) a door on a warehouse loading dock
|
a) interior hollow core flush, swinging b) solid core or wood panel, inswinging stile-and-rail, sheet metal doors c) full glass steel doors d) fire door with noncombustible mineral core e) overhead or coiling steel door
|

Why is it so difficult to make cladding watertight?
|
the five forces that contribute to water leakage make it difficult to deal with. any crack or crevice can and will be an entry for water.
|
|
|
List the functions that cladding performs and list 1 or 2 ways in which each of these functions is typically satisfied in cladding design.
|
Keeping Water Out: can use capillary breaks, drips, labyrinths, a wash, pressure-equalized wall design. Preventing Air Leakage: sealants, weatherstrips, and air barriers.
Light Control:external shading, strategic placement of windows. Heat Conduction: avoidance of thermal bridges, insulation, glazing. Controlling Sound: airtight walls |
|
|
Explain the principles of sealant joint design using sketches. List several sealant materials suitable for use in the joints you have shown.
|
figures 19.12 & 19.14
|
|
|
What are the forces that can move water through a joint in an exterior wall? How can each of these forces be neutralized?
|
Gravity: slope internal surfaces of joints towards the outside (wash)
Momentum: design each joint as a labyrinth Capillary Action: use capillary breaks Surface Tension: use drips Wind: pressure-equalized walls |
|
|
List the potential range of functions of a finish ceiling and of a finish floor
|
Ceilings: controls diffusion of light and sound, resists the passage of fire, assists in distribution of conditioned air
Floors: visual aesthetics, affect the acoustics, interact with light, primary wearing surfaces of a building, resistance to fire |
|
|
What are the advantages and disadvantages of a suspended ceiling compared to a tightly attached ceiling?
|
+) can hide mechanical & electrical, can serve as a membrane fire protection,
|
|
|
When designing a building with its structure and mechanical equipment left exposed at the ceiling, what precautions should you take to ensure a satisfactory appearance?
|
the design of mechanical and structural work. higher labor costs and to make sure the drawings and specs tell exactly what results are expected
|
|
|
List several approaches to the problem of running electrical and communications wiring beneath a floor of a building framed with steel or concrete
|
cellular raceways, cellular steel decking, poke-through fittings, raised access flooring, undercarpet wiring systems
