Building Façades: Natural Morphological Adaptations for Evaporative Cooling

Building Façades: Natural Morphological Adaptations for Evaporative Cooling | Biomimicry | Scoop.it

"The overheating of buildings and their need for mechanical cooling is a growing issue as a result of climate change. The main aim of this paper is to examine the impact of surface texture on heat loss capabilities of concrete panels through evaporative cooling. [...] A systematic process was been undertaken to examine the impact of different variables on the cooling ability...[...] This study demonstrates the potential exploitation of morphological adaptation to buildings, that could contribute to them cooling passively and reduce the need for expensive and energy consuming mechanical systems."

Using Saharan Silver Ants as an Inspiration for Surface Cooling Coatings

Using Saharan Silver Ants as an Inspiration for Surface Cooling Coatings | Biomimicry | Scoop.it

"Yu’s team is the first to demonstrate that the [Saharan silver] ants use a coat of uniquely shaped hairs to control electromagnetic waves over an extremely broad range from the solar spectrum (visible and near-infrared) to the thermal radiation spectrum (mid-infrared), and that different physical mechanisms are used in different spectral bands to realize the same biological function of reducing body temperature. [,,,] Their discovery that there is a biological solution to a thermoregulatory problem could lead to the development of novel flat optical components that exhibit optimal cooling."

Hydroceramic Walls Could Cool Buildings By Sweating Like Human Skin

Hydroceramic Walls Could Cool Buildings By Sweating Like Human Skin | Biomimicry | Scoop.it
Our reliance on air conditioning, however magical an innovation, has become a serious environmental burden. Which is why researchers in Barcelona designed a material they say can naturally cool rooms by about 5 degrees Celsius, using a moisture-absorbing polymer that "sweats" much like our own body.

Human Brain Inspires Use of "Electronic Blood" in IBM Computers

Human Brain Inspires Use of "Electronic Blood" in IBM Computers | Biomimicry | Scoop.it

"If you think about it, the human brain is a magical thing. It's capable of computing complicated algorithms on only 20 watts of energy, making it a computationally powerful and compact natural creation that is 10,000 times more dense and efficient than a computer. That natural efficiency has inspired IBM to create a computer fueled on liquid energy, or "electronic blood" that has the ability to carry power in and take heat out — much like the human circulatory system already does."

Termite Technology to Shape New ‘Breathing’ Buildings

Termite Technology to Shape New ‘Breathing’ Buildings | Biomimicry | Scoop.it

"Researchers are investigating how termite mounds can be used to shape future buildings which feature walls that breathe as part of a major new international study involving Nottingham Trent University (UK). The $1.35millon project will examine how the unique structure of the termite mound enables stale and fresh air to be exchanged while maintaining a comfortable level of temperature. Described as a lung by the researchers, the termite mound is the only habitat known in the animal kingdom to have been proven to exchange oxygen and carbon dioxide without losing heat, which enables termites to live in harsh climates they could not otherwise inhabit. One of the ultimate aims of the project is to create buildings which feature walls that breathe in the same way and reduce the need for central heating or air conditioning."

Silvery Hairs Turn Ants into Walking Mirrors

Silvery Hairs Turn Ants into Walking Mirrors | Biomimicry | Scoop.it

One ant species in the Sahara Desert is covered by a silvery sheen of body hair that acts as a wearable sun shield for the creatures, a new study finds. The silvery hairs completely reflect the light like mirrors, preventing the ants from absorbing too much heat. That may help to explain how the Saharan silver ants can stay cool when temperatures in the arid region reach a blistering 122 degrees Fahrenheit (50 degrees Celsisus).

Pressurised Structures – Cacti

Pressurised Structures – Cacti | Biomimicry | Scoop.it

"A cactus (plural: cacti, cactuses, or cactus) is a member of the plant family Cactaceae, within the order Caryophyllales and is a succulent system that contains pressurised water that gives the organism structural stability as well as being a fundamental life source.

Being a water-container, means that there is no need for other rigid structure such as bark to give structural performance against external loads. Water is an element already in compression and similar structural strategies have been derived from this natural phenomenon in man-made hydraulic structures."

Solar Energy: A Sunflower Solution to Electricity Shortage

Solar Energy: A Sunflower Solution to Electricity Shortage | Biomimicry | Scoop.it

"A new piece of solar technology from IBM not only provides electricity – it can desalinate water for sanitation and drinking. [...] IBM and Airlight Energy’s 30ft concrete ‘sunflower’ was inspired by the branched blood supply of the human body."

Future Windows Could Use A Biomimetic Circulatory System To Save Energy

Future Windows Could Use A Biomimetic Circulatory System To Save Energy | Biomimicry | Scoop.it

"Windows, our source of life-giving sunlight indoors, are a menace to your electrical bill. In the summer, windows bleed cold and in the winter they ooze heat. To save energy, researchers want to give window panes a circulatory system that could pump in cool, liquid relief when they get too hot. In research published in Solar Energy Materials and Solar Cells, researchers from Harvard describe an artificial vascular system, which could help make windows more energy-efficient by controlling their temperature with water."

5 Natural Air-Conditioning Designs Inspired by Nature

5 Natural Air-Conditioning Designs Inspired by Nature | Biomimicry | Scoop.it

"With heat waves gripping much of the planet, electricity grid operators are sweating even more than their customers. Air-conditioning uses a tremendous amount of energy, but a new group of designers think they can solve the problem by mimicking Mother Nature's craftiness."

Interesting thing about birds is their two-phase lungs. I did the first steps of analysis on adapting that kind of system to a building scale heat exchanger last year.
David Parr's curator insight, July 9, 2013 6:36 AM

Interesting ideas, though being inspired by tornadoes and hurricanes should be 'meteomimicry'. Also, I've always found bird's two phase lungs a more interesting model than their feet.
