The MIT-hosted Concrete Sustainability Hub has developed Break Even Mitigation Percent (BEMP), a new tool to estimate the cost of weather hazards on a building. In its July research brief, “A break-even hazard mitigation metric,” CSHub staff finds that a $10 million non-engineered wood building is expected to face more than half a million dollars in hazard related damages over 50 years, while a $10 million engineered concrete building is expected to face only $165,000 over the same period.
