According to Hawaii Building Code, what is the minimum required wind speed rating for impact-resistant windows in coastal high-wind zones?
Correct Answer
A) 160 mph
Impact-resistant windows in Hawaii's coastal high-wind zones must be rated for 160 mph wind speeds to meet hurricane protection requirements.
Why This Is the Correct Answer
160 mph is the minimum wind speed rating required for impact-resistant windows in Hawaii's coastal high-wind zones. This rating reflects the hurricane-force winds Hawaii's coastlines can experience, ensuring windows resist both wind pressure and wind-borne debris during major storm events.
Why the Other Options Are Wrong
Option C: 180 mph
180 mph exceeds the minimum required rating. While windows rated above the minimum are acceptable, 180 mph is not the threshold set by Hawaii Building Code for coastal high-wind zones.
Option D: 140 mph
140 mph is below the required minimum. Windows rated only to 140 mph would be insufficient for Hawaii's coastal high-wind zones and would not meet code requirements for hurricane protection.
Memory Technique
Associate '160 mph' with 'Category 5 territory' — Hawaii's coastal zones demand near-Category 5 rated windows (Cat 5 starts around 157 mph), making 160 mph the logical minimum benchmark.
