“The Salt Project is a biomimetic attempt to create architecture using seawater in the desert. By using locally available resources we can grow plants and create architecture without producing waste. The idea is to pump up seawater in arid areas around the world, split it in salt and fresh water, use the fresh water for produce and use the salt for architecture.” [Read more…]

I am a registered architect and I have a passion for African vernacular architecture. I recently (Sept. 2014) traveled to Malawi to document the vernacular architecture in the entire country. 4,700 pictures are on the web page.http://www.malawiarchitecture.com/
I also wanted to share with you my latest project… a data base on African vernacular architecture. This project was started because of the lack of information available on line. The data base includes images from every African country. Here is the link to the site:
http://www.africavernaculararchitecture.com/
The goal of the project is to have people, who live or work in an Africa country, submit pictures of vernacular structures to the data base to share with the world. Full credit is given for every picture submitted. For too long, African vernacular architecture has been a topic that has been both under-documented and, unfortunately, ignored. People say there needs to be documentation but yet nothing is done. Whether this is due to difficulties in obtaining funding or just apathy, the fact remains that very little data can be found online.

Architecture is as much of a part of a countries culture as is language, music or art. African vernacular architecture is disappearing. I witnessed that fact in Malawi. There are many reasons why vernacular materials and construction techniques are being abandoned in favor of western ones. One main reason is the lack of documentation, especially finding information on line.
I am hoping you could share the project with your readers, the more awareness, the better the chance to convince people to submit pictures to the data base. There is no other resource for African vernacular architecture like the data base: there is no organization gathering information, there is no active research, there is no voice for it. I will gladly answer any questions that you might have about the project.
Cheers,

“How do we go about designing buildings today for tomorrow’s weather? As the world warms and extreme weather becomes more common, sustainable architecture is likely to mean one major casualty: glass. For decades glass has been everywhere, even in so-called “modern” or “sustainable” architecture such as London’s Gherkin. However in energy terms glass is extremely inefficient – it does little but leak heat on cold winter nights and turn buildings into greenhouses on summer days.”
“For example, the U-value (a measure of how much heat is lost through a given thickness) of triple glazing is around 1.0. However a simple cavity brick wall with a little bit of insulation in it is 0.35 – that is, three times lower – whereas well-insulated wall will have a U-value of just 0.1. So each metre square of glass, even if it is triple glazed, loses ten times as much heat as a wall. Cutting back on glass would be an easy win. Windows need to be sized, not glorified, and sized for a purpose: the view, or to provide natural light or air. Windows also need to be shaded. Many would argue that we need to re-invent the window, or the building. We need to build buildings with windows, rather than buildings that are one big window.”

“In Plymouth, Massachusetts — the site of the first English colony in America — Matteo Brault spends his days living a 17th century life, along with dozens of other re-enactors on the modern-day Plimoth Plantation. Brault works full-time as a 17th-century style blacksmith, using traditional tools like a grindstone, hand-made nails and a large bellows for making the fire hot enough for forging iron and steel. He also helps build the traditional shelters.”
“The simplest homes in town were built using cratchets — natural forks in trees — as support for the ridgepole of the roof. The walls are built up with “wattle” — small sticks for the lattice structure — and “daub” — a mortar of clay, earth and grasses. Instead of using the traditional English lime wash to protect the walls, the colonists took advantage of the plentiful wood in the America and created clapboard siding by cleaving wood into thin boards. For the thatch roofs, large bundles of water reed or wheat straw are woven with a giant needle by two people working in tandem (one outside and one inside). “It’s like a giant quilt made of grass,” explains Brault, “which makes a water-tight roof that essentially acts as a giant sponge. It absorbs water and laps it off.”

Almost a quarter of a million windmills worldwide will need to be replaced by 2030. The rotor blades are made of valuable composite materials that are difficult to recover at the end of their energy generating life. New generation rotor blades made of glass or carbon fibre composite material have average lifespans of between 10 and 25 years. Recycling of glass fibre composite is possible though complex. Recycling of the more highly valued carbon fibre composite is currently impossible. In many EU countries landfill of carbon composites is now prohibited. Thus, many rotor blades at the end of their wind turbine life are currently shredded and incinerated. At current growth rates, by 2034, there will be about 225,000 tonnes of rotor blade composite material produced annually, worldwide.
The Dutch firm Superuse Studios has found a solution to the growing mountains of waste generated by the wind industry: making use of end-of-life rotor blades in design and architecture. The realised projects demonstrate the technical applications and potential for blade made designs and architecture. In their second life as design and architectural elements, rotor blades could be used for a further 50-100 years, or more. Blade made designs are durable, iconic, compete economically, and reduce the ecological footprint of projects in which they are used. [Read more…]
“All across America, blocks of older, smaller buildings are quietly contributing to robust local economies and distinctive livable communities. This groundbreaking study demonstrates the unique and valuable role that older, smaller buildings play in the development of sustainable cities.
Building on statistical analysis of the built fabric of three major American cities [San Francisco, Seattle, and Washington, D.C.], the research demonstrates that established neighborhoods with a mix of older, smaller buildings perform better than districts with larger, newer structures when tested against a range of economic, social, and environmental outcome measures.”
