Featured Certified Building: St. Anthony Hospital – Lakewood, Colorado

St. Anthony Hospital

In June, St. Anthony Hospital in Lakewood, Colo., achieved its second consecutive ENERGY STAR certification. How did they do it? Key to the hospital’s success was the formation of an energy optimization team in 2012, comprised of St. Anthony’s facility operators and managers as well as professionals from design, commissioning, and controls and construction firms. In 2013, the team implemented a number of measures which will reduce their energy use by an estimated 8 percent and save $84,000 annually.

Energy savings measures implemented in 2013 include the following:

  • Reprogrammed air flow in operating rooms to achieve variable flow – this reduces flow to the minimum flow required by code, but allows for air flow to increase quickly in response to surgery staff requests for cooler room temperatures. This measure saves fan, chilled water, and boiler energy when the extra air is no longer needed to cool the space; more than 80 percent of the occupied periods do not require extra air.
  • Administrative area occupancy scheduling – space temperature and setpoints were programmed to achieve fan and plant energy reduction during unoccupied periods.
  • Anesthetizing Area Humidity reduction – the hospital took advantage of an ASHRAE 170 change recently adopted by CMS that allows minimum humidity in anesthetizing areas to be reduced from 30 percent to 20 percent; this is a big energy saver in Colorado's dry climate

EPA’s ENERGY STAR National Building Competition: Battle of the Buildings

For the sixth consecutive year, EPA’s ENERGY STAR program is hosting the National Building Competition: Battle of the Buildings to help school districts and organizations improve the energy and water efficiency of their buildings, save money, and protect the environment.

Improving energy efficiency in buildings is the single most effective way to eliminate energy waste. Energy use in commercial buildings accounts for nearly 20 percent of total U.S. greenhouse gas emissions and energy use at a cost of more than $190 billion per year. On average, 30 percent of the energy used in commercial buildings is wasted. Most of the energy used in the buildings where we work, play, and learn comes from the burning of fossil fuels at power plants, which contributes to climate change. The less energy we use, the fewer greenhouse gases we produce.

Be a Winner!

In the spirit of popular weight-loss competitions, participants from all 50 states and the District of Columbia are battling it out to see who can reduce their energy and water use the most. More than 125 teams and more than 6,500 individual competitors are measuring and tracking their building’s monthly energy and water consumption using ENERGY STAR® Portfolio Manager®, EPA’s online measurement and tracking tool. Many will work toward earning ENERGY STAR certification, the symbol of superior energy efficiency.

 Battle of the Buildings

EPA will recognize the overall Top Teams and Top Buildings, determined by the percentage-based reduction in energy or water use achieved between 2014 and 2015. EPA will also recognize Top Buildings by building category using the same metrics, as well as all individual and team competitors who reduce energy or water use by 20 percent or more between 2014 and 2015.

Previous competitions provided a valuable platform for organizations to test innovative approaches and technologies that can be expanded to entire building portfolios. Today, the results of previous competitions serve as a source of best practices, lessons learned, and public energy performance data that can help inform the commercial building market. Achievements of past competitors are summarized in wrap-up reports on the competition website.

EPA maintains a competition website featuring a list of competitors and their “weigh-in” results, as well as tips and links to EPA’s existing inventory of ENERGY STAR tools and resources.

ENERGY STAR® Brand Awareness Continues to Grow

Brand Recognition Increases

May 2015, Washington, DC – Results from the National Awareness of ENERGY STAR® for 2014 are now available. Analysis of the data from the fifteenth annual Consortium for Energy Efficiency (CEE) household survey shows the strength of the ENERGY STAR brand by measuring label recognition, understanding, and influence on purchasing decisions.

Consortium for Energy Efficiency

Consistent adherence to the brand tenets by EPA and DOE and long-term brand promotion by members of CEE and trade allies has paid off. In 2014, 89 percent of households recognized the ENERGY STAR label when it was shown to them. This constitutes an increase of 48 percent since CEE first conducted the survey in 2000.

“This year’s survey results show that the ENERGY STAR label continues to be strongly recognized and used by the majority of Americans,” observed Kira Ashby, Program Manager with Evaluation, Research and Behavior at CEE. “This research demonstrates the continued impact efficiency program administrators have in promoting the label, and CEE members are proud to support this report.”

Washington, D.C., Emerges for the First Time as Top City with the Most ENERGY STAR Certified Buildings

Today, the U.S. Environmental Protection Agency (EPA) announced the 2015 list of top cities with the most ENERGY STAR certified buildings. For the first time since 2008, a city other than Los Angeles leads the rankings. Washington, D.C., debuted in the top spot with 480 ENERGY STAR certified buildings in 2014. These and other cities across America are seeing the important role that their buildings can play in reducing greenhouse gas emissions.

“This list shows how America’s cities are leading the nation in cutting carbon emissions and fighting climate change,” said Jean Lupinacci, chief of the ENERGY STAR Commercial & Industrial program. “By embracing energy efficiency as a simple and effective pathway to reach their sustainability goals, these cities are demonstrating the tangible benefits that result from simple, cost-effective reductions in energy use.”

2015 Top Cities Infographic

In most cities, commercial buildings are the largest source of carbon emissions. Chicago, for example, estimates that the energy used by buildings accounts for 70 percent of the city’s carbon emissions. In New York City, that figure jumps to nearly 80 percent.

To date, more than 25,000 buildings across America have earned EPA’s ENERGY STAR. These buildings have saved more than $3.4 billion on utility bills and prevented greenhouse gas emissions equal to the annual electricity use from 2.4 million homes.

Energy use in commercial buildings accounts for 17 percent of U.S. greenhouse gas emissions at a cost of more than $100 billion per year. ENERGY STAR certified office buildings cost $0.50 cents less per square foot to operate than average office buildings, and use nearly two times less energy per square foot than average office buildings. Commercial buildings that earn EPA’s ENERGY STAR must perform in the top 25 percent of similar buildings nationwide and must be independently verified by a licensed professional engineer or a registered architect. ENERGY STAR certified buildings use an average of 35 percent less energy and are responsible for 35 percent less carbon dioxide emissions than typical buildings. Many types of commercial buildings can earn the ENERGY STAR, including office buildings, K-12 schools, hotels, and retail stores.

ENERGY STAR® is the simple choice for energy efficiency. For more than 20 years, people across America have looked to EPA’s ENERGY STAR program for guidance on how to save energy, save money, and protect the environment. Behind each blue label is a product, building, or home that is independently certified to use less energy and cause fewer of the emissions that contribute to climate change. Today, ENERGY STAR is the most widely recognized symbol for energy efficiency in the world, helping families and businesses save $300 billion on utility bills, while reducing greenhouse gas emissions by two billion metric tons since 1992.
