The Great Plains Institute has compiled a list of all the Energy Star certified buildings in Minnesota, hoping to set a baseline of information and look for the progress being made in Minnesota toward resource saving.
Buildings that are Energy Star certified use 35 percent less energy than a typical commercial building, according to the report. Overall, Energy Star buildings save $2 billion in energy costs nationwide in more than 300,000 buildings that are tracked with Energy Star’s Portfolio Manager.
There are 561 Energy Star buildings in Minnesota ranging from schools and office buildings to warehouses and commercial buildings such as retail shops, banks and senior care facilities. And those buildings cover a total of 105 million square feet of space.
Trevor Drake, of the Great Plains Institute and one of the report’s authors, said earning an Energy Star rating can be tough. “The candidates need to enter 12 months of energy usage into Portfolio Manager, the EPA’s tracking tool,” he said. “Then, they need to have a professional engineer look at their data and verify the results.”
A score of 75 means that a building is more efficient than 75 percent of the 300,000 surveyed buildings. But only 20,000 buildings nationwide have earned Energy Star certification.
In Rochester, there are eight Energy Star buildings, with Cottagewood Senior Community—formerly Sunrise Cottages—a senior living facility earning a perfect 100 score in 2012. It was the second certification for the building; it earned a 98 in 2011.
