The concept of a bubble has surprisingly inspired many designers within the construction industry in recent years. There’s the inflatable bubble building in Shanghai that is supposed to help air and light quality, the inflatable tunnel that will protect pedestrians and business during road construction in Canada, and even a solar cell that was created to be lighter than a soap bubble. We can now add Binishells to our list.
Binishells are flowing, domed concrete buildings that utilize air as their formwork. Once the slab-on-grade foundation is laid, an air filled bubble, called a pneumoform, is inflated and rebar is placed around it accordingly. Concrete is then sprayed on the form and rebar to create the exterior shell. When hardened, the form is deflated and ready to use on the next project.
The building process began in the 1960’s, when the current owner, Nicolo Bini’s, father developed the technology. The company touts several benefits on its website, including:
- ½ the cost to build and operate
- ⅓ the lifecycle footprint in terms of sustainability
- ½ the resources, of which all are locally sourced,
- Resistance to natural disasters
- 3 times faster to build
- MInimal upkeep and easily repurposed.
Bini’s current focus is on tackling homelessness and he hopes Binishells can be the solution. You can watch the video below, from Mashable, for some additional information about the product.
Dubai has been on the bleeding edge of pushing the boundaries of construction for over a decade. The famous Burj Khalifa, the current World’s Tallest Building, but the United Arab Emirates on the map. Since then, the country has poured money and resources into the construction industry and have sets their sights on a new challenge: 3D construction printing.
Across the United States, any mass timber building designed to be taller than six stories high has to receive special approval from the building codes department. After a recent addendum was added to the Oregon’s building code, the state has become the first in the country to allow high rise mass timber buildings without receiving any special considerations.
Last summer, Tesla announced that the first of their solar roof tiles had been installed on test houses. However, as has become customary with many Tesla products, the company is experiencing significant manufacturing delays.
Since the dawn of green buildings, these projects have always been synonymous with LEED certification. The process of obtaining that LEED certification has not always been an easy one for contractors; there is a ton of paperwork and documentation that needs to take place in order to prove all LEED credits have been rightfully earned. A new construction standard, called BREEAM, is hoping to disrupt the United States’ green building certification world with its impending New Construction Standard Release in 2019.
One of the biggest hassles of site work in construction is the hauling away of spoils. It’s costly and time consuming to bring in truck after truck to take unneeded soil off to an unknown dump site. When Elon Musk and his team, The Boring Company, started digging a tunnel for a HyperLoop system in Los Angeles, they knew there had to be a better way to handle to soil than to haul it away.
The following is a guest post written by Laurence Banville, Esq.
With much talk about climate change both politically and socially, citizens and the business world have started to calculate the way in which climate change will alter how we live and work. In the past, the construction industry has made a number of speculations about how it would change as the planet gets warmer, however, changes have only started coming in light of the rising temperatures and their effects on the industry.
The USGBC recently released their 2017 data for the Top 10 US States for LEED construction, which is sorted by Gross Square Footage per Capita. That ranking system allows them to get a fair comparison of states, despite differences in population and number of buildings.
As the world not only becomes more familiar with green products, but also starts demanding them, researchers and contractors alike need to be ready to embrace the ever-changing world and meet their customer’s demands. Each year, new products are released that hoping to reduce waste or harness renewable energy sources, but only some of them reach the mass market.
Below are 8 green products, processes, and stories that we found most interesting in 2017:
Wood construction has typically been used for purely residential products in the past few decades and especially after fire protection standards became more stringent. Besides fire rating, concrete and metal has several other benefits over wood, including overall strength, resistance to insects, and resistance to rot. Wood, however, does have some advantages over concrete and steel, like its relative light weight and it’s much less harmful to the environment.
The Netherlands has a ton of bridges, especially pedestrian and biking bridges, thanks to its abundant system of canals. Perhaps because of that, they have become a leader in 3D printing technology when it comes to bridges.
