Gulf Coast Green Symposium 2009
Reducing the Regions’ Footprint: options for reducing the region’s carbon and ecological footprints while we continue to grow and consume
The presentation by Steve Dumez, FAIA, Design Director for Eskew+Dumez+Ripple architects based in New Orleans, reviews the history and key issues of Sustainable Design within the building industry. In addition, the overall cost and environmental impact of LEED-certified building is broken down by rating and long term benefit.
15. Note: Percentages shown are from a 2007 survey.
Voters in a recent study attributed just 4% of
greenhouse gas emissions to buildings.

21. Coal, Oil and Natural Gas
(non-renewable hydrocarbons)
represent over 2/3 of all energy
sources used to generate
electrical power.
22. BP, a company that has spent nine
years saying it was moving “beyond
petroleum”, has been getting back
to petroleum since 2007, paring
back its renewable program…..
…..In its long-term forecast, Exxon
says that by 2050, hydrocarbons –
including oil, gas, and coal – will
account for 80 percent of the
world’s energy supplies, about the
same as today.

55. PREMISE: Architects need to re-engage the forces of nature
(sun, wind, water) to inform design and foster an
ecologically based future.
Three Key Steps toward 2030 readiness:
build on “sustainable” and “high-performance” initiatives
#1 - Reduce loads/demand FIRST (utilize passive heating, cooling and
ventilation, day lighting, sun shading, building orientation, etc.) – BACK
TO BASICS
#2 - Meet loads efficiently (utilize energy efficient lighting, high efficiency
MEP systems, advanced controls, etc.)
#3 - Use on-site generation / renewables to meet energy needs (doing
steps 1 & 2 before will result in the need for much smaller renewable
energy systems – making carbon neutrality achievable)
56. What can we learn from the vernacular
architecture of our region that we can
incorporate into our work today?
Provide overhanging roofs to shade walls/windows
Promote ventilation
Use lightweight materials that do not hold heat
Use stack effect to ventilate through high spaces
Raise above grade to protect against flooding
Cistern water collection to maximize resources

75. MISSION:
To demonstrate, educate and engage New Orleans youth in Emeril’s
Central Green, an urban farm and eco-friendly interpretive center that
teaches farm-to-table philosophies about food origins, healthy cooking,
nutrition and healthy lifestyle choices, regional food culture and history,
and the creativity and possibilities that can result from these experiences.
