Could Fujitsu Pave the Way for Data Center Energy Ratings?

In November of 2013, Fujitsu claimed the first National Australian Built Environment Rating System award of four stars for its data center facility, the Noble Park Data Centre. The facility demonstrates how high demands of energy can be met with little impact on the environment. The four star rating indicates it is 20-percent more efficient over similar structures that rate at a three-star level.

Financial Reasons to Improve Your Home's Energy Rating

Increasing a home’s energy rating score isn't merely about helping the environment or committing yourself to a "greener" way of living. The Home Energy Rating System (HERS) Index is the industry standard by which a home's energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home's energy performance.The HERS is actually a system that determines how energy efficient the home is and how much potential there is for the occupant to save money.

Australia's Ambitious Commercial Building Disclosure Policy

We recently sat down to talk with Bronwyn Shirley, the Assistant Director of Australia's Commercial Building Disclosure Program. Shirley works at the Department of Climate Change and Energy Efficiency implementing this exemplary policy.

How Benchmarking Makes Cities Smarter

2013 looks like it will be a banner year for building energy benchmarking and disclosure policies. With Philadelphia’s policy adoption closing out 2012 on a high note, Minneapolis got us started strong in January of 2013—becoming  the seventh U.S. city, and the first in the Midwest, to pass a policy requiring transparency of energy performance in large commercial buildings.

How DC Crunched the Numbers on Its Own Buildings

In his State of Union address this week, President Obama mentioned that Americans need not a bigger government but a "smarter government." Washington, DC’s city government started a movement towards smarter operations back in 2009 – by measuring and publicly reporting the energy use of all its buildings. That includes the government's own buildings.

What Explains the Success of NABERS?

Australia’s Commercial Building Disclosure (CBD) program has now been fully implemented for over a year, and about 66 percent of Australian office space has an energy rating.  Under the program, sellers or lessors of office space greater than 2,000 square meters (approximately 22,000 square feet) are required to disclose a Building Energy Efficiency Certificate (BEEC) if the space is being sold, l

Benchmarking on Two New Continents

National programs for benchmarking buildings’ energy use can be found in the U.S., Europe, China, and Australia. But new players on the international stage, with growing economies and influence, are joining the ranks. Energy performance benchmarking is on the rise in Brazil and South Africa, too.

SEED and the Possibilities of Open Energy Data

Last month, New York City became the first jurisdiction in the U.S. to publicly post energy efficiency information for its building stock. The data—a maze of mind-numbing Excel tables—is hard to sort through. But it’s a critical first step to opening up energy transparency in the real estate market. As we’ve noted, benchmarking and disclosing energy efficiency info is a rapidly growing trend among U.S. cities.

What has changed in DC’s new benchmarking regulations?

On July 20, the District of Columbia took an important step towards fully implementing DC’s groundbreaking energy benchmarking law by publishing a new proposed rulemaking in the DC Register, along with supporting guidance documents published online. DDOE has made numerous substantive changes since the last proposed rulemaking last October. You can download all these documents, including an extensive FAQ, on the District Department of the Environment (DDOE) website.
