Girls in STEM, featuring young women scientists and engineers who wowed the President and the nation at the White House Science Fair in February, shines a spotlight on these extraordinary young role models and their exciting projects — ranging from a machine that detects buried landmines, to a prosthetic hand device, to a lunchbox that uses UV light to kill bacteria on food. http://www.pbs.org/newshour/rundown/girls-stem-take-center-stage-white-house-science-fair/
Build Change CEO Elizabeth Hausler Strand recently attended both the World Economic Forum on Latin America and the World Economic Forum on East Asia, connecting with economic issues related to our disaster risk reduction program in Colombia and our post-disaster recovery programs in Indonesia and the Philippines. Build Change presented at the World Urban Forum in Medellín, Colombia in early April to encourage the use of retrofitting as a cost-effective approach that makes buildings safe and fosters community resiliency.
Our Chief Operations Officer took this photo in Haiti today. “T-shelters” or “transitional shelters” are a popular solution in post-disaster situations. They’re built to withstand earthquakes and hurricanes, to keep residents from being displaced again. They are expensive and subtract funds which could be used for retrofitting damaged homes or rebuilding homes. A family is living in this t-shelter, which is three years old now and clearly deteriorating. By some estimates, the [2010 earthquake in Haiti] killed 200,000 people and made 1.3 million homeless overnight by destroying or damaging 172,000 homes or apartments. But the new projects do not necessarily … Read More
Look at the top of the wall. The decision to lay the top course of blocks on its side for extra ventilation was an extremely bad one, making it so the seismic load in the roof slab has no competent load path to the shear wall below. In the retrofit evaluation our engineers give this wall no credit for seismic resistance–it will have to be fixed.
Written by Elizabeth Hausler Strand I started Build Change 10 years ago with the mission of reducing deaths and injuries from housing collapses during earthquakes. It was the 2001 earthquake in Bhuj, India that inspired me – most people were killed because their house collapsed on them. It is possible and affordable, even in an emerging nation, to build houses and schools that don’t collapse in earthquakes or hurricanes – it’s a man-made problem with a man-made solution. By building safe buildings, we reduce the need for emergency services, wound care, infection prevention, and so on. But we don’t actually … Read More
By Gordon Goodell, Build Change Chief Operations Officer Feb. 27, 2014 Years before I came to Build Change I worked on a mountain rescue team. The first rule for rescue is “My safety, and the safety of my team.” At Build Change we work to limit our risk to the extent possible by ensuring that all buildings we use are seismically safe. By the nature of what we do, most of our staff at Build Change spend a lot of time in zones of high seismic hazard. We make our best effort to ensure that offices and other buildings rented by … Read More
Sure, if they’re designed and built to be safe in earthquakes At Build Change we mostly teach people to build masonry houses or timber houses. We do not use plastic bottles, tires, straw bales, earth bags, or any number of other approaches which have been touted as environmentally-friendly, cost-effective methods to rebuild devastated areas. Why? What’s wrong with homes made from waste materials? Or plastic bottle houses? Or straw bale houses? Well, nothing, really. A lot of argument goes on over whether one building system is better than another, particularly in the seismically active zones where we work. There are … Read More
The problem we have at Build Change is that the destruction in the wake of major natural disasters is so huge and the need to rebuild is so great, that we don’t have enough hands to rebuild it all. Teaching local people how to build an entirely new, unfamiliar structural system, whether it is earthships, plastic bottle homes, or precast concrete panels, adds unnecessary work to an already enormous task. Instead, we choose to work within the systems and designs the local builders already know and use. We teach about lateral systems and connections, which make structures able to withstand … Read More
