Climate Change Resilience by Blunt Force Instrument

By Energy Rant No Comments
Per the last couple of posts, we examined policies, trends, and physics behind property destruction, storms, and fire. This week provides ways to avoid destruction and loss from fires, floods, hurricanes, tornadoes, and extreme cold, which we are experiencing again. Have you seen the temperatures in Florida lately? Construction of Choice One type of construction can serve as the answer for many climate-related hazards, and that would be insulated concrete forms (ICF) with appropriate roofing and exterior finishes. (The third little pig had a point, ya know) The white sections in the drawing represent the insulating forms, which are typically…

Climate Resilience – Tornadoes, Canes, and Curve Balls

By Energy Rant No Comments
This week we continue responding to the reader question, “What kind of home can withstand fire, hurricanes, floods, heat domes & polar vortex?” Before we get into design considerations, let’s look at modes of failure. From my research, hurricanes and tornadoes function similarly with similar wind speeds. Their difference is size and duration, of course. Let’s look at the scales used for hurricanes (Saffir-Simpson) and tornadoes (Enhanced Fujita). Tornado and Hurricane Engines Low-pressure systems, tornadoes, and hurricanes all spin counterclockwise in the northern hemisphere, and they all represent rising air. Rising air results in cloud formation (condensation), and if the…
