Engineers must design more efficient internal combustion engines capable of running on alternative fuels such as alcohol, and new research into battery power should be undertaken… Wind motors and solar engines hold great promise and would reduce the level of CO2 emissions. Forests must be planted… - Prof. Svante August Arrhenius, 1925 01 Feb 2008 R.

Economic sustainability Man-made capital (buildings & equipment) Weak sustainability 01 Feb 2008 vs Environmental sustainability Natural capital (natural resources & ecosystem services) Strong sustainability R. Shanthini Examples of Natural Capital: Natural resources such as - water, minerals, biomass and oil Ecosystem services such as - Land which provides space to live and work - Water and nutrient cycling - Purification of water and air - Atmospheric and ecological stability - Pollination and biodiversity - Pest and disease control - Topsoil and biological productivity - Waste decomposition and detoxification 01 Feb 2008 R. Shanthini Weak (or Economic) Sustainability Sustainable development is achievable as long as Total (which is natural plus man-made) Capital remains constant. It means it is okay to reduce the natural capital stocks as far as they are being substituted by increase in the man-made stock. Increasing man-made stocks provide high incomes, which lead to increased levels of environmental protectionism. (Substitutability Paradigm) 01 Feb 2008 R. Shanthini Strong (or Environmental) Sustainability Sustainable development is achievable only when the natural capital is maintained constant independently from man-made capital. (Non-substitutability Paradigm) Substituting man-made capital for natural capital leads to disaster. Examples? Boats for Fish Pumps for Aquifers Saw mills for Forests 01 Feb 2008 R. Shanthini Radical Resource Productivity (or Eco-efficiency) 01 Feb 2008 R. Shanthini Radical Resource Productivity (or Eco-Efficiency) The Industrial Revolution led to a radical increase in the productivity of labour and capital at the cost of exploitation of natural resources since they are considered abundant. What we need now is a radical increase in the productivity of resources since we know that natural resources are indeed limited (examples: trees, oil and fish). 01 Feb 2008 R. Shanthini Radical Resource Productivity (or Eco-Efficiency) dramatically increases the output per unit input of resources (such as energy, man-made materials & natural resources such as air, water, or minerals). 01 Feb 2008 R. Shanthini Radical Resource Productivity (or Eco-Efficiency) World Business Council for Sustainable Development (WBCSD) has identified the following seven elements of eco-efficiency: - reduce the material requirements for goods & services - reduce the energy intensity of goods & services - enhance material recyclability - maximize sustainable use of renewable resources - extend product durability - increase the service intensity of goods & services - reduce toxic dispersion 01 Feb 2008 R. Shanthini Whole System Design 01 Feb 2008 R. Shanthini Whole System Design optimizes an entire system to capture synergies. WSD requires creativity, good communication, and a desire to look at causes of problems rather than adopting familiar solutions, and it requires getting to the root of the problem.

One heat-transfer loop was designed to use 14 pumps totaling 95 horsepower by a top Western firm. Dutch engineer Jan Schilham (using the methods learned from the efficiency expert Eng Lock Lee of Singapore) cut the design’s pumping power use by 92% to just 7 horsepower Source: http://stephenschneider.stanford.edu/Publications/PDF_Papers/LovinsLovins1997.pdf 01 Feb 2008 R. Shanthini Whole System Design How was that possible? The pipes diameter was increased. Since friction falls as nearly the fifth power of pipe diameter, small pumps were enough. Pipes were laid out first, and then the equipment were installed. The pipes are therefore short and straight, with far less friction, requiring still smaller and cheaper pumps, motors, inverters, and electricals. The straighter pipes also allowed to add more insulation, saving 70 kilowatts of heat loss with a twomonth payback. Source: http://stephenschneider.stanford.edu/Publications/PDF_Papers/LovinsLovins1997.pdf 01 Feb 2008 R. Shanthini Whole System Design What about the cost? When optimizing the lifecycle savings in pumping energy plus capital cost of not just the pipes but of the whole system, the extra cost of the slightly bigger pipes was smaller than the cost reduction for the dramatically smaller pumps and drive systems. Whole-system life cycle costing is widely used in principle, but in practice, energy-using components are usually optimized (if at all) over the short term, singly, and in isolation. Source: http://stephenschneider.stanford.edu/Publications/PDF_Papers/LovinsLovins1997.pdf 01 Feb 2008 R. Shanthini Whole System Design Like the engineering profession itself, engineering education is often compartmentalized, with minimal consideration of systems, design, sustainability, and economics. The traditional design process focuses on optimizing components for single benefits rather than whole systems for multiple benefits. This, plus schedule-driven repetitis (i.e., copy the previous drawings), perpetuates inferior design. Source: http://www.frugalmarketing.com/dtb/10xe.shtml 01 Feb 2008 R. Shanthini Whole System Design Rocky Mountain Institute kicked off Factor Ten Engineering (“10XE”), a four-year program to develop and introduce pedagogic tools on wholesystem design for both engineering students and practicing engineers. The focus is on case studies where whole-system design boosted resource productivity by at least tenfold, usually at lower initial cost than traditional engineering approaches.

Shanthini Biomimicry (or Bionics) 01 Feb 2008 R. Shanthini Biomimicry (or Bionics) Study nature, observe its ingenious designs and processes, and then imitates these designs and processes to solve human problems. 01 Feb 2008 R. Shanthini Interactions between organisms in an ecosystem (symbiosis): Mutualism: both populations benefit and they need each other for survival Protocooperation: both populations benefit but the relationship is not obligatory Commensalism: one population benefits and the other is not affected 01 Feb 2008 R. Shanthini Interactions between organisms in an ecosystem (symbiosis): Amensalism - one is inhibited and the other is not affected Competition – one’s fitness is lowered by the presence of the other Parasitism – one is inhibited and for the other its obligatory 01 Feb 2008 R.

Shanthini Biomimicry (or Bionics) Termite mounds include flues which vent through the top and sides, and the mound itself is designed to catch the breeze. As the wind blows, hot air from the main chambers below ground is drawn out of the structure, helped by termites opening or blocking tunnels to control air flow.

Shanthini Biomimicry (or Bionics) Trapped air in the interstitial spaces of the roughened surface of the lotus leaf results in a reduced liquid-to-solid contact area. This allows water's self-attraction to form a sphere. However, due to natural adhesion between water and solids, dirt particles on a leaf's surface stick to the water. Since a ball rolls easily, the slightest angle in the surface of the leaf (e.g., caused by a passing breeze) causes balls of water to roll off the leaf surface, carrying away the attached dirt particles.

Shanthini Biomimicry (or Bionics) GreenShield™ coats textile fibres with liquid repelling nano particles in order to create water and stain repellency on textiles, and results in a 10-fold decrease in the use of environmentally harmful fluorocarbons, the conventional means of achieving repellency. Other products inspired by the Lotus Effect include Lotusan paint and Signapur glass finish. http://biomimicryinstitute.org/case-studies/ 01 Feb 2008 R. Shanthini Biomimicry (or Bionics) Polyaramid Kevlar, a tough fiber that can stop bullets, is made by pouring petroleum-derived molecules into a pressurized vat of concentrated sulfuric acid and boiled at several hundred degrees Fahrenheit in order to force it into a liquid crystal form, which is then subject to high pressures to force the fibers into alignment as we draw them out. The energy input is extreme and the toxic byproducts are odious. The spider manages to make an equally strong and much tougher fiber at body temperature, without high pressures, heat, or corrosive acids. If we could learn to do what the spider does, we could take a soluble raw material that is infinitely renewable and make a super-strong water-insoluble fiber with negligible energy inputs and no toxic outputs. Janine Benyus, 1997 01 Feb 2008 R. Shanthini A multidisciplinary (engineering, science, social science, and governance) process of solution development that takes a holistic view of natural and human system interactions is known as Earth Systems Engineering. - US National Academy for Engineering Earth System Engineering emphasizes five main characteristics that apply to all branches of engineering: Characteristic 1 Our ability to cause planetary change through technology is growing faster than our ability to understand and manage the technical, social, economic, environmental, and ethical consequences of such change. Since modern engineering systems have the power to significantly affect the environment far into the future, many engineering decisions cannot be made independently of the surrounding natural and humanmade systems. http://www.naturaledgeproject.net/ESSPCLP-Intro_to_SD-PreliminariesKeynote1.aspx 01 Feb 2008 R. Shanthini Characteristic 2 The traditional approach that engineering is only a process to devise and implement a chosen solution amid several purely technical options must be challenged. A more holistic approach to engineering requires an understanding of interactions between engineered and non-engineered systems, inclusion of nontechnical issues, and a system approach (rather than a Cartesian approach) to simulate and comprehend such interactions. http://www.naturaledgeproject.net/ESSPCLP-Intro_to_SD-PreliminariesKeynote1.aspx 01 Feb 2008 R. Shanthini Characteristic 3 The quality of engineering decisions in society directly affects the quality of life of human and natural systems today and in the future. http://www.naturaledgeproject.net/ESSPCLP-Intro_to_SD-PreliminariesKeynote1.aspx 01 Feb 2008 R. Shanthini Characteristic 4 There is a need for a new educational approach that will give engineering students a broader perspective beyond technical issues and an exposure to the principles of sustainable development, renewable resources management, and systems thinking. This does not mean that existing engineering curricula need to be changed in their entirety. Rather, new holistic components need to be integrated, emphasizing more of a system approach to engineering education. http://www.naturaledgeproject.net/ESSPCLP-Intro_to_SD-PreliminariesKeynote1.aspx 01 Feb 2008 R. Shanthini Characteristic 5 Multi-disciplinary research is needed to create new quantitative tools and methods to better manage non-natural systems so that such systems have a longer life cycle and are less disruptive to natural systems in general. http://www.naturaledgeproject.net/ESSPCLP-Intro_to_SD-PreliminariesKeynote1.aspx 01 Feb 2008 R. Shanthini Creativity is not so much having a new idea as stopping having an old idea. - Inventor Edwin Land Green indoor walls Home for an ecologist 01 Feb 2008 R. Shanthini
