Answer: C

Explanation:

Implementing passive design strategies should be the primary focus as they utilize the climate to maintain a comfortable temperature range in the building, reducing the reliance on mechanical heating and cooling systems. This approach can significantly improve energy performance and reduce operational costs by maximizing natural heating, cooling, and daylighting before considering mechanical or electrical systems.

Reference: The LEED v4 Reference Guide for Interior Design and Construction emphasizes the importance of passive design strategies within the integrative process for optimizing energy performance1. Additionally, the LEED v4 energy update reflects a focus on increased energy efficiency and greenhouse gas emissions reductions, which can be effectively addressed through passive design23.
