ARCH 4561 Final Exam

Natural Step

Developed by Swedish oncologist Karl Henrik Robert in 1989, this system provides a framework for considering the effects of materials selection on human health. The basic principles, or The Four Systems Conditions, assert that in order for a society to be sustainable, • Nature's functions and diversity are not systematically... 1. ...subject to increasing concentrations of substances extracted from the Earth's crust. 2. ...subject to increasing concentrations of substances produced by society. 3. ...impoverished by over- harvesting or other forms of ecosystem manipulation. • Resources are used fairly and efficiently in order to meet basic human needs globally.

(Croxton)

Precautionary principle

Requires the exercise of caution when making decisions that may adversely affect nature, natural ecosystems and global biogeochemical cycles.

Precautionary principle

Requires the exercise of caution when making decisions that may adversely affect nature, natural ecosystems and global biogeochemical cycles. The Four Tenets of the Precautionary Principle: 1. People have a duty to take anticipatory action to prevent harm. 2. The burden of proof of harmlessness of a new technology, process, activity, or chemical lies with the proponents, not the general public. 3. Before using a new technology, process, or chemical, or starting a new activity, people have an obligation to examine a full range of alternatives, including the alternative of not doing it. 4. Decisions applying the Precautionary Principle must be open, informed, and democratic and must include the affected parties.

Life-Cycle Analysis (LCA)

A method for determining the environmental and resource impacts of a material, a product, or even a whole building over its entire life. All energy, water, and material resources, as well as all emissions to air, water and land are tabulated over the entity's life cycle. The life cycle, or time period, considered in this evaluation can span the extraction of resources, the manufacturing process, installation in a building, and the item's ultimate disposal. The assessment also considers the resources needed to transport components from extraction through disposal.

Sim Van der Ryn and Stuart Cowan's 5 Ecological design principles

• Solutions grow from place: Every location has its own character and resources. • Ecological accounting informs design: The impact of all decisions must be taken into account, not just economic factors. • Design with nature: Foster a collaboration with natural systems - mimic nature. • Everyone is a designer: The participatory process is key. • Make nature visible: Celebrate natural systems through architectural features.

Biomimcry

• The conscious emulation of life's genius. • "Doing it nature's way has the potential to change the way we grow food, make materials, harness energy, heal ourselves, store information, and conduct business." • "In a biomimetic world, we would manufacture the way animals and plants do, using sun and simple compounds to produce totally biodegradable fibers, ceramics, plastics and chemicals." Biomimetic guidelines for humandesigned systems: • Use waste as a resource • Diversify and cooperate to fully use the habitat • Gather and use energy efficiently • Optimize rather than maximize • Use materials sparingly • Don't foul the nest • Don't draw down resources • Remain in balance with the biosphere • Run on information • Shop locally

The human brain is a hybrid: an evolved hierarchy of three brains in one. A primitive "lizard" brain, designed millennia ago for survival, lies at its core and cradles the roots of the ancient dopamine reward pathways. the "border crust"—of the early mammalian brain, which is the root of kinship behavior and nurturance. The evolution of mammalian species is marked by a continuous expansion of this cortex, with the prefrontal lobes of the human brain—the powerful information-processing or "executive" brain
