As an introduction, U.S. disaster losses from wind, floods, earthquakes, and fires now average $100 billion per year, and in 2017 exceeded $300 billion-25% of the $1.3 trillion building value put in place that year. Fortunately, there are affordable and highly cost-effective strategies that policy>nakers, building owners, and the building industry can deploy to reduce these impacts. These strategies include adopting and strengthening building codes, upgrading existing buildings, and improving utilities and transportation systems. The benefits and costs associated with these mitigation measures have been identified through the most exhaustive benefit-cost analysis of natural hazard mitigation to date and documented in Natural Hazard Mitigation Saves report. This fact sheet summarizes the study findings and significant savings associated with various mitigation measures. Comm. N `�� 'I V Ref. To: I Rku 4 County of Hawaii is an Equal Opportunity Provider and Employer. Ref. Date JUL Z 1 2021 Adopting the latest building code requirements is affordable and saves $11 per $1 invested. Building codes have greatly improved society's disaster resilience, while adding only about 1% to construction costs relative to 1990 standards. The greatest benefits accrue to communities using the most recent code editions. Above-code design could save $4 per$1 cost. Building codes set minimum requirements to protect life safety. Stricter requirements can cost-effectively boost life safety and speed functional recovery.
