Project Profile: Screven Elementary School

Screven Elementary School (Screven) in Sylvania, Georgia underwent an extensive renovation but one problem still remained: an inefficient and dated HVAC system. The original pipes had deteriorated, and a simple repair was out of the question. Superintendent William Bland found a solution when he attended an educational session on our CITY MULTI® units. “The more we studied and researched and questioned other users, the more we liked the product,” said Bland.

Our VRF system provides easier maintenance with less impact on ongoing operations. The entire installation, completed in less than 12 weeks, took place during the summer when school was out of session. The system is compartmentalized, meaning one part can be serviced without having to shut down the whole system. School officials can control the cooling and heating in each individual classroom from a centralized controller as well.

That control has provided the school with substantial cost savings. The average yearly savings post-renovation is $16,226 a year. Screven was also able to remove the boiler and cooling tower, saving on both energy and gas.

Project Profile: The Market at Liberty Place

The Market at Liberty Place is a popular gathering spot for friends and families in Kennett Square, Pennsylvania. LGB Properties, LLC demolished and rebuilt the three-story, 31,000-square-foot building, which now holds nine food vendors, offering everything from seafood to pizza to ice cream and coffee. The challenge when renovating this space was finding an HVAC system that would be efficient and diverse enough to meet any vendor’s needs.

Selecting our VRF system was an easy choice. To heat the patio during the winter, the system reclaims heat from the building’s west side, where the solar load, ovens and grills are located, and transfers it to cooler areas. The same process keeps the patio cool in the summer. Inside, the system maintains a comfortable environment. “On a 100-degree humid day or a cold day, with the door opening and closing, it’s nice in there,” said Larry Bosley, president and CEO of LGB. Between the year-round occupant comfort, quiet operation, low-energy usage and ease of control, Bosley calls our R2-Series VRF system “a dynamite system.”

Project Profile: Grand Lake Mental Health Center

Economy was a big concern for Grand Lake Mental Health Center, Inc. (GLMHC) when it decided to transform a 20,000-square-foot bar and dance club into its eighth clinic in northeast Oklahoma. The challenge was finding an HVAC system that could provide the patient privacy and comfort essential to health and wellness facilities and deliver cost savings. Our R2-Series VRF system was the obvious solution.

“A risk in a therapeutic environment, where return air systems are tied together, is that voices carry,” says Larry Smith, GLMHC’s chief operating officer. The minimal ductwork of our system allows for privacy. The technology is zoned to optimize both comfort and cost savings, allowing GLMHC to control the temperatures throughout the facility based on the activity in each area. Patients undergoing exams in one part of the facility can be kept warm while patients working out can be kept cool. The system is also able to keep the on-site pharmacy’s medicine cool, despite the surrounding heat-producing equipment. Any area not in use can be shut off entirely to avoid unneeded cooling and heating.

Read the full case study to learn why Smith says our system is “the ideal design for integrated care.”

The Division Is Going Green!

Image 1
Image 2We’re thrilled to announce that our headquarters, located in Suwanee, Georgia, recently received two Green Globes from the Green Building Initiative (GBI).

Green Globes is a green building rating and certification system that awards a building one to four Green Globes based on its sustainability features and practices. According to the system, our two Green Globes demonstrate “excellent progress in the reduction of environmental impacts and use of environmental efficiency practices.”

Our Suwanee offices opened in 2013 and were designed with the Green Globes rating system in mind. In fact, the offices feature our very own Variable Refrigerant Flow (VRF) zoning systems, which contributed a substantial number of points in the Energy and Indoor Environment assessment areas. To further support our sustainable efforts, we’ve also created an Environmental Committee, whose sole purpose is to promote a company-wide focus on energy reduction, reuse and recycling. To date, the committee has successfully introduced recycling in our coffee areas and lunchroom, as well as created a wood and plastic collection area in our local warehouse.

We’re proud of this prestigious accomplishment and look forward to finding new ways to continue our commitment to sustainability. Click here to learn more about Green Globes and how to make your building a symbol of sustainable practices.

Industry Celebrates Third Anniversary of First VRF Certification Program

October 7 Image
We introduced Variable Refrigerant Flow (VRF) zoning technology to the U.S. more than 10 years ago and currently, it’s the fastest growing HVAC technology on the market. There were two critical steps in its path to industry and end-user acceptance: the passing of Air Conditioning Heating and Refrigeration Institute (AHRI) Standard 1230 and the launch of the AHRI VRF Certification Program. This year, we celebrate the third anniversary of its success.

We began working with AHRI and other HVAC manufacturers on the program in 2003. AHRI Standard 1230, the first and only standard in the world for testing VRF zoning products, was passed in 2009. The AHRI VRF Certification Program, which validates the performance of VRF zoning equipment based on the standard, was officially launched in September 2011 with five manufacturers on board – us being one of them. To date, the program includes nine manufacturer participants and 1,367 certified models with at least 168 more expected to be certified this year. We are proud to report that all of our systems that have gone through certification verification testing over the past three years have passed! Here’s why the program continues to pick up steam:

All-Inclusive: The program tests a full range of VRF capacities, from 5,000 Btu/h indoor units to 760,000 Btu/h outdoor units. It allows manufacturers to certify ratings including full load cooling capacity, energy efficiency ratio (EER), heating capacity, coefficient of performance (COP) and simultaneous cooling and heating efficiency (SCHE). The program also provides a method for testing and rating integrated energy efficiency ratio (IEER), which involves four tests at different capacities and temperatures to simulate annual usage – this is where VRF really shines.

Third-Party Validation: Products are tested, under the direction of AHRI, at a state-of-the art Intertek facility in Plano, Texas, which was designed with input from all manufacturer participants to ensure that equipment is tested fairly and accurately. Manufacturers’ performance claims are independently measured and verified by the experienced Intertek team.

Reassurance: The program ensures that manufacturers are rating and certifying their products honestly and, better yet, adhere to a higher standard when developing VRF zoning systems. It ensures that products will perform as specified, provide predictability, optimize energy efficiency and improve client satisfaction.

Check out the August issue of JARN for more information on the program. To view the certified products and ratings, go to

Project Profile: Choctaw General Hospital

Choctaw General Hospital (Choctaw) is the first and only critical access hospital in Choctaw County, Alabama. Meridian, Mississippi-based Rush Health Systems (Rush) first broke ground on the new 74,000-square-foot facility in 2012. The project team decided it could renovate an existing building for the administration portion of the new hospital but the patient care section required a new 44,000-square-foot addition and an HVAC system that could meet the specific needs of the health care environment.

Rush’s Vice President, Chief Resource Officer and Facility Manager Fred Rogers previously installed our Variable Refrigerant Flow (VRF) zoning systems in Rush’s flagship hospital and saw $36,000 in savings the first year. After witnessing the benefits of our technology firsthand, Rogers began specifying our technology for all of the critical access hospitals they build: Choctaw being the fifth.

Patient care is the top priority at Choctaw and our VRF zoning systems deliver. The individual zoning and simultaneous cooling and heating capabilities provide each patient with the most precise and comfortable environment possible.
