St. Patrick Catholic Church
Since its inception in 1910, St. Patrick Catholic Church (St. Patrick’s) in Lake Forest, Illinois, has been a place for the community to gather. Over time, as the Lake Forest community grew, the 3,900-square-foot building underwent several structural renovations to accommodate new members and guests. In 2016, after tolerating many years without air conditioning, the church decided to install a new HVAC system in an effort to make the space even more comfortable for the large congregation. It turned to Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric.
The Move
Just 30 miles south of Colorado’s state. capital, tucked away in the Colorado Mountains, sits the community of Castle Rock. With a little more than 56,000 residents, Castle Rock prides itself on its small-town charm, historic downtown, small businesses and community involvement. Over the past few years, business population began to grow exponentially, and shortly thereafter, office space quickly became limited. To prevent local businesses from moving, the town and the Castle Rock Economic Development worked together to propose a new office building called The Move – a name that symbolized how businesses wouldn’t have to move outside of city limits to expand. The town decided on a 50,000-square-foot, four-story building to house businesses from fast-growing industries like marketing, food auditing and general contracting. To keep businesses productive and comfortable in the new workspace, the project team wanted a quiet and reliable HVAC system that could meet tenant needs throughout the entire year. The solution was Variable Refrigerant Flow (VRF) systems with Hyper-Heating INVERTER® (H2i®) technology from Mitsubishi Electric.
The Bank of San Antonio
Since its inception in 2007, The Bank of San Antonio, San Antonio, Texas, has been built on strong relationships and quality service. However, when the bank’s success started to grow exponentially, it needed to find a space to accommodate employees and customers. After breaking ground on a new, 56,000-square-foot office space in 2015, the bank needed to find an energy-efficient HVAC system that offered quality comfort and control. The search ended by selecting Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric.
Asbury United Methodist Church
The Asbury United Methodist Church (AUMC) has been in operation for 228 years. Its current home in Harrisonburg, Virginia—a century old, three-story stone building— recently underwent a major renovation. As part of the effort to repair and upgrade the entire space, Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric was selected for AUMC’s education wing, classrooms and outreach room – a total of 23,000 square feet.
MacRostie Winery & Vineyards
Luke Higgins, director of operations for MacRostie Winery & Vineyards (MacRostie), Healdsburg, California, described the ultimate wine tasting room as one with “an environment of casual sophistication. It has a highend touch but is still accessible for all people.” When MacRostie created its new Estate House, it was this vision that drove the design. To offer patrons comfort and create the desired ambiance, that meant cooling and heating with a Variable Refrigerant Flow (VRF) system from Mitsubishi Electric. The result is what Higgins called “our dream tasting room.”
Drummond Island Medical Center
Drummond Island, Michigan, is home to just over 1,000 people. Toward the center of town sits the Drummond Island Medical Center, a 2,973-square-foot facility dating back to the 1950s. The center houses a medical clinic and its staff, an x-ray room, a physical therapy area, multiple labs and a dental office. After years of discomfort and needing more space, a renovation brought the facility up to current hospital standards while expanding the interior. Renovation challenges included consolidating the mechanical room, decreasing the sound traveling between rooms and ensuring a healthy environment for visitors and staff. Zoned Comfort Solutions® from Mitsubishi Electric solved every challenge while ushering in a new era of comfort.
Choctaw General Hospital
Fred Rogers, Rush Health Systems’ veteran vice president, chief resource officer and facility manager decided to renovate an existing building for the administration portion of his new hospital and enlisted architects to create plans for a new 44,000-square-foot addition to house the patient care section. For the new patient care addition, Rogers easily selected the Variable Refrigerant Flow (VRF) zoning system from Mitsubishi Electric. “Fortunately, I installed my first Mitsubishi Electric VRF [zoning] system years ago in our flagship Rush Health Systems hospital in downtown Meridian. That system saved me $36,000 the first year.
The Covenant School
The Covenant School was founded 30 years ago in Charlottesville, Virginia. The lower school, for students in pre-K through 6th grade, is located in a 65,000-square foot historic brick building dating back to 1935. With almost 300 students, faculty and staff members, the school needs to operate seamlessly. When an old boiler system became what board member Jay Taggart called a “ticking time-bomb,” the school knew a new heating system was needed. Variable Refrigerant Flow (VRF) from Mitsubishi Electric served as the ultimate answer to that need, providing zone control, air filtration and the added bonus of cooling. 
Burton Center for Arts & Tecnhology (BCAT)
The Burton Center for Arts & Technology (BCAT) serves almost 800 high school students on its Salem, Virginia, campus. Students take classes on a wide variety of topics—including automotive technology, computer information technology, mechatronics, culinary arts, performing arts and cosmetology. When the school’s old HVAC systems needed replacing, the district’s attention turned toward technologies that could ensure comfort and efficiency. For the school’s front building—20,000 square feet of offices and classrooms—that meant Variable Refrigerant Flow (VRF) from Mitsubishi Electric.
Aljoya Mercer Island
Aljoya is one of eight senior communities owned and operated by Era Living, LLC., a private Seattle-based company founded in 1987 by Eli and Rebecca Almo. A respected and recognized leader in senior living throughout the Puget Sound region, Era Living is dedicated to providing innovative housing, engaging programs and a variety of service choices for seniors. After studying the field of available HVAC systems, the Era Living design team concluded that the Variable Refrigerant Flow (VRF) technology from Mitsubishi Electric would be the most energy-efficient and cost-effective system for Aljoya’s needs. Wagner liked the Mitsubishi Electric VRF system’s unique ability to transfer heat within a building controlled by variable capacity heat pumps. He knew this would lead to considerable savings in energy costs.
