Organizational Sustainability Planning & Implementation Sustainability in Design • Presenter: Jane Ahrens, AIA, LEED AP • Date: April 19, 2010
Client Awareness - Sustainability • No consensus definition • Brundtland Report definition • Ecosystem definition
Four System Conditionsof Sustainability • In the sustainable society, nature is not subject to systematically increasing… …concentrations of substances extracted from the Earth’s crust; ….concentrations of substances produced by society; or ….degradation by physical means And that in society…. ….human needs are met worldwide. Source: The Natural step for Business:
Eco-efficiency • Incremental improvements in resource consumption, waste generation or pollution, but still violate 4 system conditions • Eco-effectiveness • Activities that work within natural systems and do not violate the four system conditions Eco-efficiency vs.Eco-effectiveness Source: Cradle to Cradle

Sustainability Schematic • Least effort spent • philosophical • Most effort • actions Source: Dancing with the Tiger: Learning Sustainability Step by Natural Step
Radical Resource Productivity • Biomimicry • Nature as model, measure and mentor • Service and Flow Economy • Provide the service, not the product • Investing in Natural Capital • the stock of natural ecosystems that yields a flow of valuable ecosystem goods or services into the future Four Central Strategies Source: Natural Capitalism
Life cycle assessment – LCA • Design for the Environment – Dfe • Ecological Footprinting – EF • Green Procurement Guidelines • EONS – Economic viability, Operational Efficiency, Natural Resource Conservation and Social Responsibility • Environmental Management Systems – EMS • ISO 14001 standards • Ecological and social accounting • LEED, Energy Star, Architecture 2030 • Sustainability Management Systems – SMS Processes
Sustainability Plan vs. EMS • EMS is NOT a Sustainability Plan • A plan full of eco-efficient endeavors will not make an organization's actives sustainable. • A Sustainability Plan can be implemented with an EMS
Process focus vs. system thinking • Using LEED as a strategy rather than a process • Commitment to incremental improvements vs. sustainability • Eco-efficiency vs. • eco-effectiveness • Isolating design team to single process rather than a fluid movement through the sustainability schematic. Conflicts in design process

What does an efficient building cost?What does an efficient car cost?
Down and dirty Hensley FieldOperations Center, Dallas, TXLEED NC v2.1 GOLD 780-acre site that previously housed the Dallas Naval Air Station reassumed by the City of Dallas, the property is being converted into both public and private use for industrial/aviation use.
Raised Floor(No added cost)existing uneven 8” – 12” slabno way to feed electrical in an open office environmentquick connect electrical rather than hard wiring saves money and time in future churnsstaining concrete raised floor panels saves resources over carpetimproved indoor air reduced energy consumption and labor for under floor HVAC

Common organizational goals reflected in built form • Elimination of “point buying” or exploiting unintended consequences of LEED • “Permission” to pursue alternative concepts in traditional terminal design expectations. Primary benefits to design process
