The EPA is recognizing 290 federal facilities for supporting renewable energy, reducing pollution and operating more efficiently in 2015.
The participants in the Federal Green Challenge, as part of the
Sustainable Materials Management Program, saved more than $21
million in natural gas, fuel oil, water, municipal solid waste and
The reduction of greenhouse gas emissions is equivalent to
annual emissions of more than 518,000 passenger vehicles with a
carbon dioxide equivalent of more than 2.4 million metric tons.
Awards are offered in two categories: data driven and narrative. Data awards are given in the categories of Waste, Electronics,
Purchasing, Energy, Water and Transportation, while narrative awards are given in Innovation, Education & Outreach and
Leadership and are self-nominating.
The Texas Army National Guard of Austin, TX, reduced 3,506
tons of municipal solid waste and construction and demolition
from landfills, saving $157,849 in tipping fees to earn the award
for Highest Increased Percentage Over Previous Year in the Waste
In the field of Energy and Education and Outreach, the
Minnesota National Guard of Little Falls, MN, earned recognition
for reducing natural gas from 121,628,235 cubic feet in 2014 to
96,582,662 in 2015, a 20% decrease.

BREEAM, the international green building certification first launched in the UK, is a step closer to full deployment in the
The BRE Group, which launched the longest-running building
sustainability designation in 1990, and Building Wise, a U.S.-based
LEED certification consultancy, partnered to create a new technical manual for BREEAM USA In-Use. The manual is based on the
international version of the BREEAM In-Use system for existing
buildings, but is tailored to the needs of U.S. buildings by accounting for American legal requirements, government regulations and
The system has no prerequisites or restrictions on the building’s
size, age or condition – just register the building online and fill out
the online self-assessment. Performance is measured in nine categories: Energy, Water, Transport, Management, Waste, Pollution,
Health and Wellbeing, Land Use and Ecology, and Materials. Users
instantly receive an unverified initial score that helps identify areas
for improvement. Certification by a licensed assessor is optional
and can be repeated every year.
The Bloc in downtown Los Angeles, which is being remodeled
into an open-air urban destination with retail, restaurant, office
and hospitality facilities, is one of the first properties to undertake
BREEAM USA In-Use. To see if BREEAM is right for your building,

Scientists have uncovered a new way to make ethanol using carbon dioxide.
Researchers have discovered that adding CO2 gas during the
deconstruction phase of biofuel production neutralizes the toxicity of
ionic liquids, making the procedure reversible and allowing the solvent to be recycled.
This discovery made by researchers at the Department of Energy’s
Lawrence Berkeley National Laboratory and Sandia National
Laboratories signals positive developments for the process of
streamlining future biofuel productions. According to this study,
using ethanol could lower production expenses by 50-65% compared
to prior methods that used ionic liquid-based pretreatments.
“Pretreatment is the most expensive part of the biofuels produc-

Pretreatment at Joint Bioenergy Institute (JBEI), a DOE bioenergy
research center led by Berkeley Lab. “If you count the whole produc-
tion cycle, pretreatment is second only to the cost of growing and
obtaining the feedstock itself.” B
