New Building Trends in Retail Facilities

Mall_560x340

The average brick and mortar store is evolving. Customer experience is paramount and store owners are now looking to building design to drive customer traffic. According to Chain Store Age, retailers are rapidly adopting interactive technology that benefits both the customer and building management. Based on their “Smart Building Trends” list, here are a few concepts facility managers should keep in mind:

Energy Efficiency is Key: According to ENERGY STAR®, “On average, 30 cents of every dollar spent on energy use in commercial buildings is wasted through inefficiencies.” ENERGY STAR suggests choosing energy-efficient systems is one of the easiest and most cost-effective ways to reduce energy use.

Use Smart Controls: Many retailers are implementing consumer-facing apps and innovations to bring in patrons, but smart technologies can also be a game-changer for building management. For example, Diamond Controls™ from Mitsubishi Electric Cooling & Heating pairs automation and facility management to allow users to control multiple systems through a single interface. Users are able to control a whole building or multiple building sites with Diamond Controls.

Augmented Reality for Maintenance: Last year, IBM stated that, “augmented reality is transforming building management.” Augmented reality allows users to experience and interact with video, images and audio ­– which are superimposed over real physical spaces and objects – through their smart devices. For example, QR codes can be programmed and scanned to reveal pertinent information about a system to a contractor. This can help easily identify any issues or errors within a system.

From an HVAC perspective, there is so much changing and evolving in the industry that can benefit retail spaces. At Mitsubishi Electric Cooling & Heating, our products reflect this evolution to provide occupant comfort and facility control.

VRF Eligible for Massachusetts Clean Energy Center Rebates

july12_2017

As part of their commitment to reduce greenhouse gas emissions across the state, Massachusetts expanded its Clean Heating and Cooling rebate program to include VRF products in all building applications. Many of our VRF systems qualify as part of the Massachusetts Clean Energy Center’s (MassCEC) five-year, $30 million investment in clean heating technology.

A few of our VRF systems were added to the list of rebate-eligible products because of their esteemed reputation for efficiency. According to MassCEC Program Manager Josh Kessler, heating accounts for around 30 percent of the greenhouse gas emissions in Massachusetts. He said, “VRF is a high-performing technology. “There have been a lot of advances in recent years and we want to increase awareness of what the technology looks like.”

The rebates cover the incremental costs associated with upgrading to VRF from a traditional system or incorporating VRF in new building projects. A MassCEC qualified, pre-approved VRF project can earn a rebate between $800 per ton and $2,000 per ton up to $250,000 depending on the project type, the system’s heating capacity and the product’s heat recovery capability.

We will continue to work with MassCEC to provide world-class clean heating technology to residents and business owners throughout the state. Eric Dubin, Senior Director of Utilities and Performance Construction, Mitsubishi Electric, said, “Clean heat is one of the few places where reducing our carbon footprint can also save people a lot of money.”

Project Profile: New York LEED Home

may3_2017

Hurricane Sandy made landfall October 2012, damaging or destroying hundreds of thousands of homes. One of those homes was a 1940s cottage that belonged to Kim Erle, LEED® AP, founder and president, Sunset Green Home, LLC, New York. When it came time to rebuild, Erle didn’t set out to build a new home, she set out to build the coastal home of the future – a highly efficient, resilient house that would stand up to storms and serve as a model for responsible building practices. The HVAC system up to the challenge was none other than our Zoned Comfort Solutions™.

It was a decision the whole project team agreed on. Rich Manning, owner, Energy Master LI Building Consultants, Hauppauge, New York, served as the project’s energy specialist. He said with zoned technology, “you can have individualized comfort, and there won’t be a duct issue because the mini-splits would have short ductwork from the attic.” From Doug Matz’s perspective, serving as the owner of Flanders Heating & Air Conditioning, Riverhead, New York, going with Zoned Comfort Solutions meant reliability. He said, “Mitsubishi [Electric] has been in the U.S. for decades . . . They have a reputation of being the best, and their service support and engineering support are second to none.” And for Erle, our Zoned Comfort Solutions meant assurance and practicality: “We really like the idea of multi-zone. It allows us to capture more efficiency despite the house’s occupancy varying greatly.”

From here, Erle filed for LEED® Platinum certification. She’s also thought a lot about how comforting it is to be in a home that will not just stand up to the weather but do so efficiently and sustainably. Luckily, she selected the right equipment for the job.

For 80 years, the historic R.J. Reynolds Building in Winston-Salem, North Carolina, served as the corporate headquarters for The R.J. Reynolds Tobacco Company, a subsidary of Reynolds America, Inc. In 2009, when Reynolds America relocated offices, the building went up for sale. But in 2014, the building gained new owners. PMC Property Group, Philadelphia, and Kimpton Hotels & Restaurant Group, San Francisco, purchased the building with the plan to offer a boutqiue hotel and luxury apartments to visitors and/or future residents of Winston-Salem.

A challenge of the Reynolds Building’s restoration was replacing the outdated HVAC system with a modern, energy-efficient system that could meet the building’s needs. The building needed an unobtrusive and whisper-quiet system while providing tenants with individual control. The mechanical contractor on the job, First State Mechanical, Boothwyn, Pennsylvania, knew Mitsubishi Electric Variable Refrigerant Flow (VRF) technology was the only solution because of its flexibility in design and installation, and because it would not cause any damage to the building’s architecture.

With technical assistance from Comfort Supply, Inc., Pittsburgh, the project team easily installed 84 outdoor units and 425 indoor units, providing the building with a maximum capacity of 5.8 million Btus. In addition to the mechanical equipment, the Reynolds Building was also outfitted with superior controls to keep its tenants comfortable year-round. For the hotel side, specifically, the building system operators have front-end control of the entire building’s HVAC system by using our Diamond Controls™. However, nearly all rooms within the apartments and hotel utilize SmartME Remote Controllers, which allows the building to conserve energy.

Through the renovation, the Reynolds Building has been given new purpose, serving as one of the greatest places to stay or live in Winston-Salem. Once again, our VRF has proven itself to be an effective cooling and heating solution in historic renovations.

A few years ago, Dan Gainsboro, founder and principal of NOW Communities, LLC, Concord, Massachusetts, built the award-winning community of Concord Riverwalk. The West Concord, Massachusetts, development consists of 13 Zero Energy Ready Homes.

While planning the development, Gainsboro faced his largest challenge ‒ finding a system that would cool and heat the homes in an unpredictable climate while also offering impressive energy efficiency. With research and expertise from ZeroEnergy Design, Boston, Gainsboro knew our Zoned Comfort Solutions™ would keep these houses comfortable and efficient even in New England’s icy winter weather.

Gainsboro said, “Japanese-designed mini-splits are just bulletproof. They require little maintenance and are reliable. And the efficiencies!” Gainsboro also noted how year-round performance was a big consideration in the selection process. He continued, “I’ve had good luck with Mitsubishi [Electric] in the past; they’re a bit ahead of the others in terms of addressing concerns related to heating.”

Since project completion, Concord Riverwalk has received media attention across the building industry, applauding its innovative concept and exceptional performance. According to Gainsboro, the residents have also been extremely pleased, especially with their homes’ comfort and low energy costs. Gainsboro said, “I think people are generally pretty satisfied with the return-on-investment for their high-performance home. I believe one resident’s daily electricity is 25 cents a day!”

Project Profile: Stash Residence

blog_1-18-2017

When Jenny and Aaron Stash wanted to settle down in Northbrook, Illinois, a suburb of Chicago, they searched for a house that would meet their requirements. For the Stashes, that meant sustainability, high indoor air quality and energy efficiency. After an unsuccessful search, the Stashes decided to build a home of their own. They carefully designed and built a three-floor, 3,500-square-foot house and incorporated many sustainable elements into its architecture. The Stashes outfitted the home with bamboo flooring, fiber-cement siding, LED lighting and one of our extremely energy-efficient cooling and heating systems.

The Stashes called in Michael S. Kollman, AIA, LEED AP and the president of SmartHaus, Inc., Prairie View, Illinois, a high-performance home design-build company, to find an HVAC system. The selected system would need to provide year-round comfort and be energy-efficient. Kollman worked with two University of Illinois engineers to find an answer for the house. The result: our Zoned Comfort Solutions™.

Kollman said, “Mini-split heat pumps with a conditioned energy recovery ventilation system would give us all the features we wanted and the highest-obtainable indoor air quality. We also looked at geothermal, radiant and forced air systems, but because the envelope is so efficient we just didn’t need a tremendous amount of energy. Mini-splits were the perfect solution.”

The Stashes’ home qualified for LEED® Platinum certification thanks, in part, to our system’s ability to reduce distribution losses and optimize energy. In addition to helping achieve LEED certification, our system also allowed the Stashes to see a great reduction in energy usage. Compared to other houses in Illinois, the Stashes’ home uses just one-quarter of the energy each month!

Project Profile: Brannon Gardens

brannongardens

Brannon Gardens is a newly built community in the suburbs of Lexington, Kentucky, offering customizable, ranch-style homes. As residents began to move in, several complained about experiencing thermal discomfort on the bedroom level. The cause: ineffective traditional HVAC. The entire community – some already built, some just spec’d – would need to find a solution to address the zoning issues. That solution: our Zoned Comfort Solutions.

William Richmond, owner and president, Richmond Mechanical, Inc., Lexington, worked with the home builder to fix the airflow issue. Richmond came to the conclusion that dampers would not solve anything and adding a second HVAC system wasn’t practical. The project team took interest in our systems’ INVERTER technology, among many other features and benefits. For Richmond, the answer was clear: “I researched all of the brands. Mitsubishi [Electric] is the only one that goes to 13 below zero. It’s the only one that has a 3-ton air handler you can put ducts on and run to multiple rooms.”

With our Zoned Comfort Solutions, residents of the Brannon Gardens community can now achieve comfort in all parts of their homes at a lower cost of operation. Many residents are also using our kumo cloud programmable controller app, which allows them to control their indoor units remotely over their smartphone, tablet or computer.

To learn about Brannon Gardens, which will build another 200+ homes in the next four years, outfitted exclusively with our cooling and heating systems, read the entire case study here.

Project Profile: David Whitney Building

davidwhitney

In recent years, there has been an effort in Detroit to restore the city’s historic downtown area. This rehabilitation included the David Whitney Building (David Whitney), which sat vacant for 15 years prior to its recent renovation. The mixed-use building now offers luxury residences, the Aloft Detroit at the David Whitney (Aloft), a restaurant and a bar.

A challenging, yet essential component of the David Whitney’s restoration, was selecting an HVAC system that could meet the 100-year-old building’s needs. The new system needed to serve the large space without disrupting any of its historic charm.

During the planning stages, developer Vince Dattilo, vice president of construction and project management, Roxbury Group, Detroit, and his team were concerned with the high cost and feasibility of running ductwork. Variable Refrigerant Flow (VRF) technology was appealing for its avoidance of this issue, as well as its impressive efficiency and reliability. Energy modeling supported VRF as the best option: Going with VRF would bring the original $6.8 million estimate for a forced-air system down to $5 million.

The project team selected VRF from Mitsubishi Electric. In addition to solving the need for low utility costs, Mitsubishi Electric’s indoor units’ clean design contributed to maintaining the building’s architectural integrity. Further, both guests and employees of Aloft appreciate the system’s high level of consistency and ability to provide personalized comfort in each individual room. Scott Mondock, Aloft’s director of engineering, called Mitsubishi Electric VRF “probably one of the best systems I’ve ever had a chance to work with.”

St. Ignatius Loyola School, Cincinnati, is the largest private school in the state. Since its original structure dates back to the 1950s, many of the classrooms did not have air conditioning, making the warmer months unbearable. In the winter, the school’s low-pressure boiler consumed a lot of gas, and in turn, cost a lot of money to run adequately. With over 1,000 K-8 students enrolled, the school’s HVAC system needed an upgrade in both comfort and efficiency.

The new system needed to meet three objectives: flexible design, easy maintenance and improved controls for cost savings. Tim Schweikert, the school’s physical plant manager, liked Mitsubishi Electric’s Variable Refrigerant Flow (VRF) technology because it offered quiet operation and efficiency. As the only two-pipe VRF system, it would also allow for flexible design for a space-constrained building.

According to Schweikert, the VRF system has exceeded expectations: “When we compare our utility bill to the one from last year, it’s about the same. Keep in mind that we didn’t have air conditioning before and that this new bill includes at least 12 weeks of air conditioning. So it’s like we got free air conditioning.”

In addition to the school’s new cooling capabilities, the system has also performed well during one of Cincinnati’s coldest winters in 15 years. Despite temperatures dropping well below zero degrees Fahrenheit, the system kept up, providing exceptional comfort.
