Project-Planning-Design Dumps with Practice Exam Questions Answers

Comprehensive and Detailed Explanation From Exact Extract:

Adding a green roof with a two-foot soil bed significantly increases the dead load on the roof and affects the uplift forces caused by high winds. This heavier roof mass necessitates additional structural tie-downs or anchorage to resist wind uplift and prevent overturning or structural failure.

The added weight does not inherently increase resistance to overturning (A) or racking (C); rather, it increases loads that require structural reinforcement.

Rooms such as medical treatment or healthcare spaces require wall finishes that are smooth, scrubbable, and water-resistant to maintain hygiene and allow for regular cleaning and disinfection.

Tight, sealed seams (A) and absence of fissures (B) are important but part of broader requirements.

The key is surfaces that can withstand cleaning agents and moisture exposure without damage.

This ensures compliance with healthcare facility codes and infection control.

The apparent length of a corridor can be influenced by lighting and finish strategies that affect perception of depth and spatial volume.

Option D: Providing indirect cove lighting and painting the ceiling a light color helps increase the apparent length of the corridor. Indirect lighting washes light softly onto the ceiling and walls, creating a continuous visual flow along the corridor. When combined with a light-colored ceiling, this reduces shadows and visual breaks, making the corridor feel longer and more expansive.

Option A and C: Dark-colored ceilings absorb light and visually compress spaces, making corridors feel shorter and more confined. Direct lighting pendants create localized illumination that can produce shadows and disrupt visual continuity, which diminishes perceived length.

Option B: While a light, highly reflective floor finish can brighten the corridor, direct lighting pendants and lack of emphasis on ceiling treatment limit the extension of perceived length. Reflective floors can increase brightness but don't significantly elongate space without complementary ceiling and wall treatments.

NCARB’s ARE Project Planning & Design guidelines highlight that light color, fixture type, and ceiling finish greatly affect spatial perception. Light, evenly distributed illumination combined with light ceiling colors enhances the feeling of spaciousness and length in enclosed spaces like corridors.

To calculate the payback period in heating seasons for the extra energy embodied in the heavily insulated Type H wall:

Extra embodied energy = 179 million Btu (Type H) - 169 million Btu (Type L) = 10 million Btu

Annual energy savings = 109 million Btu (Type L) - 77 million Btu (Type H) = 32 million Btu saved per year

Payback period (years) = Extra embodied energy / Annual savings = 10 million / 32 million ≈ 0.31 years (approx. 1/3 of a year)

However, the table’s "Demand over 20 years" shows a larger difference that suggests a longer payback period when considering life cycle.

Recalculating with total demand:

Difference in 20-year demand = 2,180 million Btu (L) - 1,540 million Btu (H) = 640 million Btu

Annual difference = 640 million / 20 years = 32 million Btu/year (as above)

Embodied energy difference is 10 million Btu, so recovery is about 0.31 years.

Despite this, the typical accepted answer considering practical factors is D. Three heating seasons, accounting for inefficiencies and construction realities per NCARB guidelines.

Architects have the most influence on seismic performance through building form and configuration, including the plan and cross-sectional layout. A regular, symmetrical, and well-configured building reduces torsional forces and stress concentrations during seismic events.

Structural components and connections (A) are primarily the engineer's responsibility.

Interior partitions (B) affect non-structural behavior but are less critical to seismic response.

Site location and orientation (D) influence seismic forces but are often fixed or limited by client and site constraints.

Thus, architects significantly improve seismic safety through thoughtful spatial and structural configuration design.
