DC Tops LEED States

The White HouseThe U.S. Green Building Council (USGBC) released the top ten states in terms of LEED certified building square footage per capita for 2010 last week. Washington DC tops the list, with almost 2 1/2 times the amount of LEED space as the second place state, Nevada. DC has over 25 square feet of LEED certified building space per person, while Nevada has almost 11.

“Using per capita, versus the more traditional numbers of projects, or pure square footage, is a reminder to all of us that the people who live and work, learn and play in buildings should be what we care about most,” said USGBC SVP of LEED, Scot Horst. “2010 was a difficult year for most of the building industry, but in many areas, the hunger for sustainable development kept the markets moving.”

The top LEED states per capita, including the District of Columbia:

  1. District of Columbia: 25.15 sf
  2. Nevada: 10.92 sf
  3. New Mexico: 6.35 sf
  4. New Hampshire: 4.49 sf
  5. Oregon: 4.07 sf
  6. South Carolina: 3.19 sf
  7. Washington: 3.16 sf
  8. Illinois: 3.09 sf
  9. Arkansas: 2.9 sf
  10. Colorado: 2.85 sf

According to USGBC, notable newly certified projects in 2010 include the Susitna Valley Jr./Sr. High School in Talkeetna, Ark.; the Wells Fargo Center in Denver, Colo.; the two International Monetary Fund (IMF) headquarters buildings in downtown Washington, D.C, which earned LEED certification for the operations and maintenance of an existing building; Parc Huron multi-use residential property in Chicago, Ill.; the Edina Crosstown Medical Building in Edina, Minn.; Barcelona Elementary School in Albuquerque, N.M.; Centennial Hills Library in Las Vegas, Nev.; The Allison Inn & Spa in Newberg, Ore.; KPMG: Greenville in S.C.; and multiple fire stations and the Bank of America Fifth Avenue Plaza in Seattle, Wash.

Of the projects represented on the list, the most common project type was commercial office and the most common owner type was for-profit organization. The cities most represented in the list were Chicago and Washington, D.C.

USGBC’s LEED green building certification system is the foremost program for the design, construction, operation and maintenance of green buildings. Over 40,000 projects are currently participating in the commercial and institutional LEED rating systems, comprising over 7.9 billion square feet of construction space in all 50 states and 117 countries. In addition, nearly 10,000 homes have been certified under the LEED for Homes rating system, with nearly 45,000 more homes registered.

Studies from M.T. Miles and Co-Authors Have Provided New Information about Transcription Factors. in our site at still university

Pain & Central Nervous System Week June 6, 2011 According to recent research from Kirksville, United States, “To examine potential mechanisms for the reduced resting membrane potentials (RPs) of mature dystrophic (mdx) muscle fibers, the Na+-K+ pump inhibitor ouabain was added to freshly isolated nondystrophic and mdx fibers. Ouabain produced a 71% smaller depolarization in mdx fibers than in nondystrophic fibers, increased the [Na+](i) in nondystrophic fibers by 40%, but had no significant effect on the [Na+](i) of mdx fibers, which was approximately double that observed in untreated nondystrophic fibers.” “Western blots indicated no difference in total and phosphorylated Na+-K+ ATPase catalytic alpha 1 subunit between nondystrophic and mdx muscle. Examination of the effects of the NF-kappa B inhibitor pyrrolidine dithiocarbamate (PDTC) indicated that direct application of the drug slowly hyperpolarized mdx fibers (7 mV in 90 min) but had no effect on nondystrophic fibers. Pretreatment with ouabain abolished this hyperpolarization, and pretreatment with PDTC restored ouabain-induced depolarization and reduced [Na+](i). Administration of an NF-kappa B inhibitor that utilizes a different mechanism for reducing nuclear NF-kappa B activation, ursodeoxycholic acid (UDCA), also hyperpolarized mdx fibers,” wrote M.T. Miles and colleagues (see also Transcription Factors).

The researchers concluded: “These results suggest that in situ Na+-K+ pump activity is depressed in mature dystrophic fibers by NF-kappa B dependent modulators, and that this reduced pump activity contributes to the weakness characteristic of dystrophic muscle.” Miles and colleagues published their study in the Journal of the Neurological Sciences (Reduced resting potentials in dystrophic (Mdx) muscle fibers are secondary to NF-kappa B-dependent negative modulation of ouabain sensitive Na+-K+ pump activity.
