    Recent Trends In Energy Management

    Posted by CleanAlert Blog Team on Jul 20, 2016 8:30:00 AM

    Throughout the United States, about $400 billion is spent on energy each year to serve commercial and industrial buildings. About 20% to 30% of this energy is lost. By now most facility managers (FMS) recognize that energy efficiency can decrease costs and aid in the bottom line, but they might still be seeking the most efficient solutions. Despite the fact that there is no “one size fits all” when it comes to efficiency solutions, the desire to innovate and collaborate is necessary.

    In fact, leading CEOs, FMS, and other executives of U.S. companies, universities, school districts, multifamily organizations, and state and local governments are happily collaborating and innovating when it comes to efficiency. By their participation in the Better Buildings Challenge—a national leadership program launched in 2011 with the goal of making commercial, multifamily, and industrial buildings 20% more energy efficient in the next decade, they’re proving that common barriers such as financing, access to data, and internal hurdles can be overcome with innovative thinking, action, and proven strategies. For the Challenge, the U.S. Department of Energy offers technical assistance and highlights innovative solutions as models for others to follow. While the solutions are varied, the results are the same: partners in the Challenge are leading the way and sharing their strategies so that other organizations can learn, adapt, and benefit.

    Retailer Improves Comfort And Savings

    Within the walls of a Best Buy store, customers understand they can find any number of energy saving products to purchase and a “blue shirt” salesperson ready to aid them. But what they don't know is that the stores themselves are energy savers. Best Buy has reduced energy use by 24% across more than 47 million square feet of retail space.

    Within its Las Vegas store, the company implemented a multi-faceted energy upgrade that involved installing skylights and a dimmable fluorescent lighting system to harvest daylight, decreasing lighting energy use by an average of 45%. Best Buy also installed sub-metering for lighting in the store, which allowed alarms and energy models to secure proper lighting schedules during unoccupied hours, employee-only hours, and store hours.

    Allowing more natural light into the store enhanced the overall customer and employee experience—especially on sunny days. Also, the retrofit is tied to an enterprise energy management system that alerts staff when critical equipment isn’t performing to capacity, allowing Best Buy to be proactive and ensure that issues are fixed before negotiating the customer or employee experience.

    Best Buy is one of the first partners to achieve the Better Buildings Challenge’s 20% portfolio-wide reduction goal.

    “At Best Buy, we set a goal to diminish our carbon emissions 20% by 2020, which aligned with the Better Buildings Initiative, making our participation an easy decision,” says Hugh Cherne, environmental sustainability senior manager for the company. “We share the belief that solutions which can be scaled, such as our 800 store lighting retrofit, lead to the greatest reduction in carbon emissions as well as improved financial performance.”

    Committed To Health And Energy Reduction

    Healthcare facilities, particularly inpatient centers, are among the most energy-intensive commercial buildings. Cleveland Clinic is doing its part to tackle the energy use of this sector by working across a portfolio of more than 60 buildings and 20 million square feet. To date, Cleveland Clinic has improved its energy performance by 5% through an employee behavior change campaign, hospital lighting upgrades, and the installation of more efficient HVAC and water systems.

    Specifically, its “Greening the OR” initiative empowers a team of surgeons and hospital staff to improve the effectiveness of operating rooms and encourages them to link patient care to smarter energy choices. These efforts provide money that previously spent to power the hospital to be reinvested into services or other building upgrades, increasing value to patients and shrinking the hospital’s carbon footprint.

    Manufacturing Energy Savings

    To manufacture gypsum wallboard (otherwise known as drywall) is highly energy intensive. However, that didn’t prevent manufacturer Saint-Gobain from building its new 500,000 square foot plant in Roxboro, NC to be as energy efficient as possible. From conception to construction, high performance was at the heart of the design of the facility.

    The company used a number of smart design innovations to enhance the plant’s energy efficiency by 10%, including employing multiple heat recovery systems in every major product process step. Using heat recovery for the gypsum board dryers alone improved efficiency by 15% over conventional methods.

    Also, as oppose to using calciners that vent process gas, the company chose direct contact calciners to contain gas and reuse the latent heat in a closed loop system, leading to improved efficiency. Additional features include a closed loop system to diminish process water usage and the reuse of in-plant wallboard scrap back into the manufacturing process. Since 2009, Saint-Gobain has decreased energy intensity across its 118 U.S. manufacturing operations by 10%.

    Cities And Schools Saving Energy

    The City of Beaverton, OR, like many municipalities, is determined to reduce energy use in its own buildings, while also cultivating a community-wide commitment to greater efficiency. In the case of Beaverton, this suggests more than 1.5 million square feet of space.

    To begin its promise to save energy under the Better Buildings Challenge, the city implemented a number of energy efficiency upgrades at the Beaverton City Library. These comprised of complete lighting and heating controls retro-commissioning. Also as part of this project, employees monitor energy usage, enabling them to identify trends, respond quickly to equipment malfunction alerts, and make changes in real time. The retro-commissioning project cost $54,600 and has saved $23,000 annually, paying for itself in less than two and a half years.

    Stevie Freeman-Montes, sustainability coordinator, Sustainability Program, City of Beaverton, says, “From an internal, organizational perspective, I believe engagement in real-time energy monitoring was a tipping point for the city to buy in and support energy efficiency. When we were able to see immediately the effects and savings from these efforts, it was immediate gratification and validation of the initiative.”

    Freeman-Montes adds, “I’m also hoping our strong cross-sector collaborations will help build momentum for other buildings throughout our community to join the Challenge and that other entities can realize actual savings and the associated positive environmental impacts.”

    Across the river in Camas, WA, the Camas School District is renovating Lacamas Heights Elementary, one of the district’s six primary schools. Completed in March 2014, the project involves some energy efficiency initiatives and is expected to achieve at least 21% savings. The project consists of numerous efficiency upgrades, covering of the refurbishment and improvement of the HVAC systems serving the Pod areas (modular classrooms), and replacement or upgrade of most of the HVAC systems working the main school building and offices. Also, the control systems were modified to improve comfort and reduce energy usage throughout the school.

    Effective Affordable Housing

    A very powerful message from the Better Buildings Challenge is that partners in every sector are demonstrating their commitment and sharing their innovative energy efficient solutions—from large corporations to schools to nonprofits. One such nonprofit is Aeon, an affordable housing developer, owner, and management firm that has built, preserved, or renovated more than 2,000 apartments and townhomes in Minnesota since 1986.

    “Becoming part of the Better Buildings Challenge made practical sense and was a quick and easy decision for Aeon,” says Gina Ciganik, vice president, Housing Development, Aeon. “We have been engaged in finding high performance, energy efficient solutions for a long time. We liked how the Challenge offered an excellent framework to organize the work of various Aeon departments as well as the opportunity to share information. Not only would we be part of a national group who could teach us, but we could also share experiences and help advance the cause.”

    After the successful completion of a multi-building, multi-family development on the western edge of Chaska, MN, the City of Chaska approached Aeon with The Landing Apartments, a new development opportunity to assist in discussing the need for affordable senior housing.

    Aeon operated closely with the city to make sure the design met the needs of current and future residents and complemented the surrounding Minnesota River and historic districts. The Landing Apartments focus is on aggressively reducing the energy consumption. Passive House principles such as superinsulation, building orientation, and thermo coupling as well as geothermal heating and cooling, were integrated into the building’s design. Savings are expected to be estimated at 34%.

    Aeon is not stopping there. They’re about to break ground on The Rose, an affordable housing development that uses Living Building Challenge standards as a sustainability framework, and is anticipated to be about 75% more efficient than the current energy code.

    By fixing the energy performance in commercial and industrial buildings by just 20%, more than $80 billion can be saved annually throughout the nation. Better Buildings Challenge partners see the opportunity, and by sharing performance data, documenting how results are obtained, and collaborating across sectors and among peers, they provide a successful model for others to follow.
