Sports Stadiums Go Green


Reducing costs, enhancing the fan experience, attracting environmentally minded sponsors – these are just some of the reasons why sports stadiums around the country are focusing on sustainable practices and operations. Greening sports facilities is uniquely challenging, however. “They get a massive influx of people in a short period of time, and then they sit vacant for days,” explains Steve D’Iorio, senior vice president at Jones Lang LaSalle in Washington, D.C.

BUILDINGS recently highlighted stadiums that successfully made the leap to the greener side. See below for some of the changes at these landmark facilities:

  • M&T Bank Stadium, Baltimore: The Baltimore Ravens’ stadium reduced energy usage by 5 million kWh between 2005 and 2012 using ENERGY STAR® The stadium was the first existing outdoor professional sports facility in the U.S. to achieve LEED® Gold certification.

  • Levi’s Stadium, Santa Clara, California: The home to the San Francisco 49ers generates its energy via three solar-paneled pedestrian bridges and one solar-paneled roof deck. The stadium installed controllable and programmable lighting and thermal comfort control systems for improved energy efficiency.

  • Lincoln Financial Field, Philadelphia: 11,000 solar panels and 14 wind turbines allow the Philadelphia Eagles’ stadium to generate almost all of its electricity on-site. Energy programs and management systems have reduced consumption by more than 33 percent.

  • Safeco Field, Seattle, Washington: The Seattle Mariners ballpark reduced natural gas use by 60 percent, electricity by 30 percent and water by 25 percent by upgrading the stadium’s lighting and mechanical systems. Side note: The MLB team also co-founded the Green Sports Alliance.

  • AmericanAirlines Arena, Miami: A building automation system monitors and controls the facility’s HVAC operations for strategic energy usage. Energy efficiency initiatives enable the Miami Heat’s arena to consume 53 percent less energy than comparable facilities.

  • STAPLES Center, Los Angeles: The home to the LA Lakers features a 1,727-panel solar array that provides up to 20 percent of the energy used, contributing $55,000 in savings per year. A variable-speed HVAC system increases the arena’s energy efficiency.

A building’s sustainability can be improved easily with “better discipline about turning things off when they’re not being used,” says Scott Jenkins, general manager of the Atlanta Falcons stadium and chairman of the Green Sports Alliance.

We agree. Controlling the facility’s mechanical systems can significantly reduce costs and conserve energy, benefitting both stadium owners and the environment. Innovative cooling and heating technology, like our Variable Refrigerant Flow zoning systems, allow facility managers to monitor and control exactly where and when energy is being used. Management can turn off units in unoccupied areas of the stadium during the week and easily turn them back on for game days to minimize energy use. VRF systems also maximize comfort. The three-level press box at the University of Notre Dame’s football stadium used to soar over 90 degrees Fahrenheit during early season games. Now, with our Y-Series VRF zoning system, the space maintains a cool and comfortable temperature.

Project Profile: Renaissance Schaumburg Convention Center


The Renaissance Schaumburg Convention Center (Renaissance Schaumburg), located in the metro Chicago city of Schaumburg, hosts up to 6,400 attendees each event. The facility restrooms are always in demand, creating an abundance of landfill waste.

Renaissance Schaumburg explored alternatives to using paper towels in the high-traffic spaces. Robert Lang, the facility’s director of engineering, said, “We ultimately decided to invest in Mitsubishi Electric Jet Towels for two reasons: quieter operation than competing hand dryers and the ability to contain water rather than spilling it onto the floors and walls. We wanted a drain tank that would keep the restrooms safe and dry for our guests.”

The Jet Towel is the only hand dryer to meet National Sanitation Foundation Standard 169, and its clean operation comes at no reduction in effectiveness or comfort; it dries hands in 10 seconds at a decibel rating equivalent to elevator music. Best of all, Renaissance Schaumburg reported saving $6,000 per year by using our energy-efficient hand dryers.

How VRF Zoning Help Hospitals Save


There were 7,156 hospitals in the U.S. in 1975; currently, there are 5,723. The competition among hospitals to attract patients, and thus stay in business, has never been stiffer. As Harvard Business School Professor Michael Porter explained at the recent Hospital of Tomorrow Conference, hospitals that provide the highest value care at the lowest cost will outlast those that don’t, so cost savings is key.

FacilitiesNet.com’s Executive Editor Greg Zimmerman points out that hospitals can start saving with energy management. Hospitals are one of the largest consumers of electricity in the commercial sector so managing a building’s energy usage smartly and efficiently can offer substantial savings. You need to be able to evaluate the building’s performance and have hard data in order to optimize its efficiency and reduce energy costs. “We collect data so we can understand operational and demand profiles. When you focus on how systems are being used, where there is inherent energy waste, you can determine where the energy savings are,” said Michael Della Barba, director of commissioning services at Environmental Health & Engineering, Needham, Massachusetts.

Cooling and heating contributes to nearly half of a building’s energy consumption. So outdated, inefficient HVAC systems can be significant energy drains. Hospitals that choose Variable Refrigerant Flow (VRF) zoning systems make a particularly wise investment. Here’s why:

  • Zoning. Although hospitals provide around-the-clock care, seven days a week, not even half of the facility is used 24/7. You wouldn’t leave every light on in a hospital, only the ones in the occupied rooms. The same is true for HVAC. The zoning capabilities of VRF zoning systems give hospital administrators control where and when energy is spent by conditioning only the areas in use.

  • Control. VRF zoning systems feature intelligent, intuitive controls that allow facility managers to easily and conveniently control the building’s systems. Our CITY MULTI Controls Network lets them set an operating schedule tailored to the needs of the patients, staff and the building.

  • Savings. In addition to lower utility bills, some of our VRF zoning systems are ENERGY STAR®-qualified and can help earn tax rebates. VRF zoning systems are cost effective over time as well. The systems’ payback period is just 10 years.

New Study Puts Green ROI to the Test

March 6_SBRA Home Energy Testing Image 2

Now, more than ever, it is important to distinguish which technologies will give homeowners and building owners the most bang for their buck. What energy saving benefits truly justify the costs of the products themselves?

To answer that question, we’ve signed on as a research sponsor along with the System Building Research Alliance (SBRA) and other manufacturers to conduct a year-long study on energy performance. Co-sponsored by the U.S. Department of Energy Building America Program and underwritten by Tennessee Valley Authority (TVA), the study will monitor the performance of three test manufactured homes – one that meets HUD thermal standards, an ENERGY STAR® home and the first manufactured DOE Challenge Home-certified home in the U.S.

The data will be incredibly valuable as it will paint a clear picture of the impact energy-efficient systems have on a home and the energy saving possibilities. This will, in turn, provide important insight into what efficiency improvements are worth investing in.

We’ll be sure to share our findings. In the meantime, click here for SBRA’s press release on the upcoming study.

Residential Energy Guarantee: Equipping Green Builders with Evidence

1.214 blog image

Results from an independent study found that people are 70 percent more likely to purchase a home and 75 percent more likely to choose builder-suggested products if they had an energy guarantee. With that in mind, Bonded Builder Warranty Group launched a new Residential Energy Guarantee program that provides third-party verification of a home’s energy performance and savings – allowing builders to prove their construction’s energy efficiency without facing skepticism or doubt from their clients.

The Residential Energy Guarantee is based on the Home Energy Rating System (HERS) rating report projections on the total energy use of the home. As a testament to the validity of the program, Bonded Builders Warranty Group will pay a home buyer for any additional annual natural gas and electric costs that are over the HERS project for qualifying energy-efficient homes.

As an added incentive, Bonded Builders Warranty Group is offering a special discounted pricing for builders who partake in the Home Innovation Research Labs National Green Building Standard (NGBS) Green Certification Program. For participating builders, Bonded Builders Warranty Group will offer the guarantee at the same price that is usually only available for builders purchasing more than 100 guarantees per year, making energy-efficient construction more appealing and affordable for even the lowest-volume home builder.

To learn more about how both builders and home buyers can benefit from the Residential Energy Guarantee, read the article from BUILDER magazine here, and visit www.mitsubishipro.com for energy-efficient HVAC products that’ll help secure the guarantee.

Project Profile: Miami University, Oxford, Ohio


Founded in 1809, Miami University of Ohio (Miami) is the 10th oldest public university in the country. When Miami decided to develop a plan to grow its campus and shrink energy costs, renovating its two oldest buildings, Elliott Hall and Stoddard Hall, became the top priority. Another aspect of the plan was to end on-campus coal burning by 2025, which sparked the search for a cooling and heating replacement for the two halls.

Doug Hammerle, director of energy systems at Miami, knew that a geothermal system was the way to go. Because temperatures underground in Ohio stay relatively constant over the year, the geothermal well fields remain at a steady temperature, maximizing energy savings.

When Hammerle presented the school’s plan to nearby Cincinnati distributor Habegger Corporation, Brian Isaacs, director of corporate sales at Habegger, immediately knew what system would be ideal for the halls. Having read that modular water-source systems were the industry’s most advanced technology to partner with existing geothermal loops, Isaacs recommended that the university install our water-source VRF zoning systems.

Our systems replaced the existing boiler/chiller system for the two buildings. Accessible mechanical rooms in the attic of each hall now house three heat pumps and a centralized controller. Custom wood cabinets encase the indoor units to preserve the historic architecture of the halls’ interiors. Most importantly, the new VRF zoning systems allowed for a 61 percent decrease in energy usage, making the two oldest buildings now the most energy-efficient on campus.

“Renovation of any historic building is a complex undertaking requiring a balance between the original architecture and modern building systems,” said Alec R. Carnes, senior principal at the project’s mechanical engineering firm, Heapy Engineering, Dayton, Ohio. “Mitsubishi Electric’s superior VRF engineering allowed us to preserve this historic architecture and control energy efficiency, two goals important to Miami University.”
