Project-Planning-Design Exam Dumps : ARE 5.0 Project Planning & Design (PPD)

Comprehensive and Detailed Explanation From Exact Extract:

A raised access floor system provides a flexible, accessible space beneath the finished floor for routing power, data, telecommunications, and security cables. It facilitates easy reconfiguration and tenant fit-out modifications without major disruption.

Poke-through systems (A) provide limited point access for power/data and are less flexible for extensive rewiring.

Cellular deck systems (B) are structural components, not distribution systems.

Flat cable wiring (D) is a wiring method but does not provide the physical infrastructure for flexibility.

Comprehensive and Detailed Explanation From Exact Extract:

Designing lighting systems based on initial lamp lumen output (the maximum light output when lamps are new) without accounting for lumen depreciation (light loss over time) typically leads to increased number of lamps or fixtures to compensate for future light loss, ensuring adequate illumination throughout the system's life.

This approach does not directly affect glare (B, D).

It does not decrease the number of lamps (A); it often increases them for safety margin.

Comprehensive and Detailed Explanation From Exact Extract:

For efficient weekend cooling in a multi-story office building, placing fan equipment centrally between the conditioned spaces reduces duct lengths, allows better zoning, and minimizes energy use.

In option C, fans are located mid-building between office floors and other uses, allowing for more efficient distribution and individual zone control.

Other options (A, B, D) place fans either all at one end or stacked at one side, increasing duct runs and reducing flexibility in zoning, which can lead to inefficiency during reduced loads like weekends.

NCARB PPD guidelines emphasize mechanical system design that optimizes equipment placement to balance energy efficiency, occupant comfort, and system flexibility.
