Devastating hurricanes like Andrew and Katrina have resulted in new disaster-mitigation efforts as communities rebuild buildings and infrastructure. The recent deluge of hurricanes in Texas, Florida, Puerto Rico and the U.S. Virgin Islands also offer an opportunity to use state-of-the art strategies to improve rebuilt communities’ ability to withstand future natural disasters.
These resilience strategies include energy efficiency measures. According to a recent newsletter from the U.S. Department of Housing and Urban Development’s Office of Policy Development & Research, materials and technologies that enhance buildings’ energy efficiency can also make them more durable and resilient to hurricanes and other natural disaster.
“Although these efforts may incur additional costs or slow construction or rebuilding, high-performance buildings generate significant long-term savings in energy costs, increase the structures’ durability and reduce the waste produced from damaged or destroyed buildings,” the newsletter states.
The HUD newsletter lists specific energy-efficiency measures that also help protect buildings against natural disasters, including:
In the chaos during and after a natural disaster, energy-efficient buildings may not be a priority. Developers, homeowners, communities and governmental entities may also have different goals when it comes to rebuilding. That’s why the National Association of State Energy Officials and its 56 state and territory energy offices recommend making energy efficiency part of disaster mitigation planning and response.
For instance, NASEO’s Resiliency Through Energy Efficiency report says strong working relationships between utilities; private-sector partners; and federal, state and local agencies before a disaster strikes allows for better response, recovery and rebuilding efforts. And if there are already energy-efficiency building codes, energy-efficiency and renewable-energy financing mechanisms, and consumer education efforts in place, that can also make post-disaster rebuilding quicker and more effective.
The HUD newsletter also details how communities can be proactive in both energy efficiency and disaster planning. For instance, solar panels, biomass and heat pumps on buildings in flood zones not only save energy, but remain operational during high-water events like hurricanes.
Microgrids allow a community to disconnect from a utility during a natural disaster. They also encourage on-demand energy usage on an everyday level. And energy-efficient smart meters can provide crucial information to utilities about the location of power outages during natural disasters.
“Energy efficiency is an essential component of any resilience strategy because it aids emergency response and recovery, helps with disaster mitigation, and provides social and economic benefits,” the HUD newsletter concludes.
