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.

Comprehensive and Detailed Explanation From Exact Extract:
Location C is centrally located near the main entrance lobby and accommodates program requirements. It aligns with circulation patterns and building massing necessary to support efficient vertical transportation and access to all unit types, including bicycle storage.
Locations A and B are less centralized or do not provide convenient access, making C optimal.

Comprehensive and Detailed Explanation From Exact Extract:
Central building automation systems (BAS) monitor and control HVAC and other systems to optimize energy efficiency by selecting the best combination of available systems and adjusting operation based on demand and conditions. This reduces energy consumption and operational costs.
BAS does not eliminate the need for facility managers (A), who oversee broader operations.
It aims to reduce, not increase, energy costs (C).
BAS is applicable to all mechanical systems, not limited to solar or natural cooling (D).

Comprehensive and Detailed Explanation:
Dewatering during construction (A): The deep excavation (20' below grade) near sea level likely intersects the water table, necessitating dewatering to keep the site dry during construction.
Water table height (B): Proximity to the coast raises the water table, which affects foundation and waterproofing design.
Potential corrosion due to salt (D): Salt in water vapor and marine air can corrode metal exterior finishes and reinforcements; materials and coatings must be selected accordingly.
Hydrostatic pressure on basement walls (E): High water tables create significant lateral water pressure requiring robust waterproofing and structural resistance.
Spread footings (C) may or may not be suitable depending on soil but are not specific to coastal or basement conditions.
Radiant flooring (F) is unrelated to site conditions and more a mechanical choice.
