Project Profile: Fogo de Chão

feb23

In recent years, Fogo de Chão® (Fogo), the famous Brazilian steakhouse, headquartered in Dallas, Texas, opened a New York City location directly across the street from the Museum of Modern Art, on W. 53rd St. between 5th and 6th Avenues. For its HVAC needs, Fogo selected our Variable Refrigerant Flow (VRF) zoning technology to ensure that guests remain comfortable while dining. Our technology offered the company cost savings over the chilled water system that was originally specified.

The original HVAC design, a water plant on the roof, posed issues of code-compliance, cost and unsightly ductwork for Fogo. The HVAC contractor on the job, Stanley Berger, CEO, Arista Air Conditioning Corp., Queens, New York, proposed VRF as the solution to avoid any issues and to offer the restaurant cost savings. Berger said, “VRF’s simultaneous cooling and heating capability means you can have heat coming from one handler, cooling from another – any combination you want. There’s tremendous energy savings to that.”

Following Berger’s proposition to use VRF, Fogo did an energy analysis to see how the technology would perform in comparison to the chilled water system. VRF dropped the current load by 300 amps, offering tremendous cost savings. However, Fogo was still curious about VRF’s operation, and was unsure if zoning would work well for the restaurant. After seeing VRF in action at multiple installation sites across New York City, Fogo was convinced.

Since installation, VRF has worked tremendously in the new location. It has allowed Fogo to take advantage of the cost savings and to offer complete comfort for dining guests.

Project Profile: Concord Riverwalk

jan26

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: Tiny Surf House

In the early 2000s, the tiny house trend hit the ground running when homeowners wanted to embrace a simplified lifestyle. As featured on HGTV’s Tiny House, Big Living, tiny house owners Mark and Jen Athanacio loved this new lifestyle because it combined affordable living and comfort in a small space. However, these advantages also came with a question – how can you adequately cool and heat a 224-square-foot house?

When the Athanacios moved from an efficiency apartment to a tiny house in Naples, Florida, they wanted an HVAC system that would provide quality cooling and heating without the stress of having to pay hefty household bills. The Athanacios worked with Speedy Air Conditioning, Inc., Naples, one of our Diamond Contractors™ to select a system that would also give them the ability to adjust airflow throughout the small space.

Limited interior space can be a challenge, but our Zoned Comfort Solutions™ proved to be a perfect fit for this tiny house. Just because the Athanacios’ cooling and heating system is small and their bills are low doesn’t mean their comfort is reduced. Talking about our M-Series system, Mark said, “It’s so quiet. I’m standing under [the indoor unit] right now and still talking on the phone! Overall, it’s just been fantastic. The system is so much more efficient and it looks so much better than window units. I don’t know why more people don’t do this.”

Project Profile: Fahnestock House

Few problems create as much of a challenge in HVAC design as small spaces. This challenge became very familiar to all involved in the renovation of Fahnestock House (Fahnestock) in Gettysburg, Pennsylvania. The building, which provides housing to the elderly and disabled, has 26 apartments ranging in size from 420 to 600 square feet. Fahnestock needed an energy-efficient HVAC system that could handle such tight spaces and long runs for copper lines due to the building’s design.

Only one system was able to meet those needs: our M-Series heat pump. Our indoor units measure only eight inches in height, allowing optimal living space for the residents. Our system also offers up to 100 feet for line sets, providing the necessary design and installation flexibility. “Of all the companies, this is the only one I could get to work. The configurations just fit perfectly,” said Contractor Ken Adams, Ken Adams Mechanical, Inc., New Oxford, Pennsylvania.

The HVAC overhaul improved more than just occupant comfort, however. Window units were replaced with air handlers installed behind the drop ceiling, improving the aesthetics of the building inside and outside. It also significantly improved the building’s efficiency, resulting in a 40 percent decrease in monthly energy bills.

Never Leave ‘Home’ Without ‘Ready’

Last month, we shared how green rating systems stack up. Now, we are focusing on just one of those ratings – Zero Energy Ready Home (ZERH).

What is a ZERH and why is it called that? The ZERH rating endorses the sustainability and high efficiency of a Zero Energy home and protects builders from false pretenses with the addition of ‘Ready.’ A ZERH is at least 40 to 50 percent more efficient than a traditional home but what separates it from a home with zero utility bills is a renewable energy system. It can almost offset its annual energy consumption but many factors can affect utility costs, such as homeowner habits, occupancy levels and adverse weather conditions.

Take the ZERH-certified Village Park Eco Home in Double Oak, Texas, for example, which saves almost $1,700 a year in utilities. Its efficiency earned the home the 2014 Housing Innovation Award and has garnered the attention of over 1,300 tourists. Builder Wayne Atkins said building the Village Park Eco Home was an easy decision and a step in the right direction. He intends on making it a Zero Energy Home to increase his savings even more. He shared, “solar may not be cost effective now but, in a few years it will be and we’ll be ready for it.”

Atkins isn’t the only one going to the greener side. More and more builders and homeowners are willing to put in a little now to get a lot out later. They’re willing to position themselves for better efficiency by making smarter choices for the home. Cooling and heating accounts for nearly half of a home’s energy consumption so, for those heading down the ZERH path, installing a high-performing HVAC system like ours would be a smart place to start.

Project Profile: Westgate Apartments, Champaign, Illinois

Westgate apartment complex, Champaign, Illinois, is a residential community of 23 two-story buildings with 380 one- and two-bedroom apartments. Developer Todd Atkins, The Atkins Group, Urbana, Illinois, acquired the property in 1997 with the knowledge that the original 1970s through-the-wall PTAC units would eventually need replacing. In 2014, after ever-increasing energy costs, resident noise complaints and maintenance staff spending up to one-third of their time repairing the outdated units, Atkins decided it was time to upgrade.

Atkins turned to ActOnEnergy® All-Electric Homes Program (AEH) offered by Ameren Illinois, a local utility company that offers energy services. AEH focuses on reducing electric consumption by replacing inefficient and outdated systems with air-source heat pumps or ductless technology. Due to Westgate’s high-use electric resistance heating, the program offered to cover 90 percent of the retrofit costs. Atkins contacted Troy Lanz, president of Champaign’s Lanz Heating & Cooling, Inc. to find an HVAC system that qualified for the program upgrades. Lanz recommended our MXZ multi-zone heat pump system for the job.

With little room for ductwork, our ductless, two-pipe systems offered the perfect solution to maximize the space. The systems’ flexible design also offered a quick and easy installation that resulted in minimal impact on Westgate residents, requiring only one day to install each apartment unit. The best result? The zone control feature allowed Westgate to save one-third on energy costs for vacant units just two months after the project’s completion.

The Most & Least Energy Expensive States

August 19_Most and Least Expensive States For Energy Costs ImageEver wonder the energy cost differentials between state lines? Differences in energy prices can have a big impact on monthly costs for homes and businesses. ECOBUILDING Pulse recently released an interactive heat map of the U.S., which shows where each state falls in terms of total energy costs. The map ranks the states based on the monthly energy consumption averages and the electricity, natural gas and fuel costs recorded in the U.S. Energy Information Administration’s 2012 Electric Sales, Revenue, and Average Price and WalletHub’s Most and Least Energy Expensive States reports.

Colorado, Washington state and Montana currently lead the nation in lowest total energy costs. New England states are some of the most expensive and Hawaii has some of the highest energy costs in the country, landing in the lists of top five states with the highest electricity and natural gas prices.

You may be surprised by the drastic differences in energy costs from state to state. The report shows that electricity costs four times more in some states than others, and natural gas costs nearly six times more in Hawaii (the most energy expensive state) than in Colorado (the state with the lowest energy costs).
