Study Suggests Southern Cities Are Surprisingly Sustainable
ANN ARBOR, Mich.—U.S. cities in warm climates are generally thought of as less sustainable than their northern counterparts because of their climates' impacts on water and energy resources. However, a new study comparing Minneapolis and Miami found that the Minnesota city is three-and-a-half times as energy demanding as the Florida city. The study did not look at actual energy consumption. Rather, it calculated differences in energy demand by comparing heating and cooling degree days in each location, the energy efficiency of heating and cooling appliances, and the efficiency of power plants. The study is published in the journal Environmental Research Letters.

Owners of Energy-Efficient Homes Less Likely to Default on Mortgages
CHAPEL HILL, N.C.—A new University of North Carolina study suggests that owners of energy-efficient houses are less likely to default on their mortgages and that there is a connection between monthly savings on utility costs and the probability customers will pay their loans on time. The researchers found that mortgages on homes with Energy Star recognition were on average 32% less likely to default compared with loans on homes with no energy-efficiency improvements.

Facebook to Build Green-Roofed Second HQ Building
MENLO PARK, Calif.—Facebook has been given municipal approval to build a 433,555 ft2 (40 300 m2) second headquarters building. The building will have a sloping design as high as 73 ft (22 m) in some areas and only 45 ft (14 m) in others. It will be covered by an expansive green roof with oak trees. The new building, designed by noted architect Frank Gehry, will connect to Facebook's existing headquarters via an underground tunnel.

Building Commissioning Boom Under Way, Says Study
BOULDER, Colo.—The demand for building commissioning services is accelerating worldwide, according to a new report by Navigant Research. North America will lead the world in the expanding market, accounting for $13.8 billion, or nearly half, of the $28.8 billion in total worldwide revenue for building commissioning services during the period from 2012 to 2020. Over time, the delivery of commissioning services will be transformed through the advent of building energy management systems with continuous commissioning capabilities, according to the report.

Meet an Embedded Energy Engineer
HALIFAX, Nova Scotia—David Bligh is employed by Efficiency Nova Scotia. However, his time is spent at municipal health-care provider Capital Health, where he has the unusual title of "embedded energy engineer." His job is to handle energy inefficiency problems everywhere from the large kitchen in the Veterans Memorial Building to the operating rooms in the infirmary. Unlike many large institutions, Capital Health doesn’t have a manager dedicated to energy efficiency, so it contracted with Efficiency Nova Scotia, an independent, regulated organization. “We are putting me in there and… trying to prove the fact that this (position) is valuable,” Bligh said. “I can find enough projects to more than pay for my salary, and we can save money.”

Illegal Fuels Scheme Leads to 15-Year Sentence
WASHINGTON—A businessman has been sentenced to 188 months in federal prison, fined $175,000 and ordered to pay more than $54.9 million in restitution for his scheme  to defraud the U.S. Environmental Protection Agency (EPA). The man falsely represented that he was in the business of producing biodiesel fuel, yet he did not have a biodiesel fuel-producing facility. Instead, his business operation consisted of falsely generating renewable fuel credits and selling them to oil companies and brokers. He instructed purchasers to wire payments to a bank account he solely controlled, and as a result, more than $41 million was deposited into that account.

2013 Version of Standard 90.1 to be More Stringent
The 2013 version of ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings, is scheduled for publication later this year. Many changes are being proposed to strengthen its requirements. The 2013 version of the standard includes a 40% whole building energy cost goal, and a 50% target for regulated loads. Twenty-six addenda are proposed for the standard. Twenty-two proposed addenda are open for public comment until April 21. One is open for comment until April 28. Three are open until May 6.
