Developer chooses ductless HVAC system for the Lofts at Empire Yards

Georgia developer chooses ductless systems for their performance, quiet operation, and efficiency 'in a nice, sleek package.'

When developer Brooks Patterson, owner of Prodigy Woodworks, first came across a 120-year-old former ice and coal warehouse in Macon, Ga., he envisioned Lofts at Empire Yard as a modern, multifamily property housing 28 units.

“The neighborhood was in rough shape but had these beautiful buildings needing revitalization after 50 years of neglect,” said Patterson. “We decided to buy all of the property along the street to spaces scattered throughout and give turn into multifamily units with some retail the neighborhood new life.

“I was drawn to the Empire Coal Company building in particular for its bones and history. It was built in 1897 and a lot of the architectural elements from that period have become popular again in industrial loft apartments. These elements include beautiful, large windows, high ceilings and solid structural beams.”

HIGH CEILINGS RAISE CONCERNS

Patterson set out to renovate the building’s 65,000 sf of space into loft-style apartments, adding a pool and rooftop patios, while thoughtfully incorporating its historical design elements. But the high ceilings that Patterson knew would be aesthetically appealing to future tenants were concerning when it came to specifying mechanical systems.

“A lot of people remodel older buildings and keep the existing ductwork, but I’m not a fan of that look,” said Patterson. “I chose ductless systems because they can offer performance, quiet operation, and efficiency in a nice, sleek package. I wanted my tenants to enjoy those benefits and the low utility bills that came with them. My next step was finding the right manufacturer.”

Patterson found the solution with Mitsubishi Electric Zoned Comfort Solutions® .

CHOOSING THE RIGHT HVAC SYSTEM

Patterson didn’t have much professional experience with Mitsubishi Electric systems but had recently installed a split-ductless system in his own home and was happy with the performance. What sealed the deal on ductless was the glowing recommendation from mechanical contractor Clay Etheridge, owner of Etheridge Heating and Air, Forsyth, Ga.

“We wanted the best systems for this project, so we went back and revised our budget to put Mitsubishi Electric units in the Lofts,” said Patterson. “The upfront mechanical costs may have been higher than I’d initially planned, but Clay’s commitment to standing behind the brand gave me confidence that I’d see a return on my investment quickly. As a matter of fact, my tenants have such low energy bills that the units are already paying for themselves.”

Etheridge and his team recommended a combination of Mitsubishi Electric EZ FIT™ Recessed Ceiling Cassettes complemented by Designer Series Wall-Mounted Indoor Units.

“The ceiling cassettes were a great choice for the Lofts’ ceilings,” said Etheridge. “They fit nicely between the old building’s standard-width ceiling joists so there was no need for additional construction efforts. We also appreciated their sizing because we could place them nearly anywhere, including the corner of a room and just adjust airflow to blow in the most desirable direction. We also found that they hid wiring well, giving us a really clean-looking end result.”

The ceiling cassettes can be serviced from below, automatically simplifying any maintenance requests that might come in.

MAINTENANCE REQUESTS AT A MINIMUM

Regarding maintenance requests, there’ve have been minimal requests for service.

“In this sort of adaptive reuse project, where we take a very old building and transform it, a lot of people expect that the mechanical systems won’t be up to snuff,” said Patterson. “Even if we’ve completely gutted the place and started from scratch, they see the old industrial footprint and assume they’ll be dealing with boilers and radiators. It’s been fun to see tenants pleasantly surprised by the Mitsubishi Electric system – how well it performs, how quiet it is, and how easy it is to control.”

The easy operation is thanks to use of Mitsubishi’s kumo cloud wireless control software (https://www.mitsubishicomfort.com/kumocloud). Zoned Comfort Solutions systems can use kumo cloud to give tenants user-friendly control over their apartments’ temperature through a wall-mounted tablet or remote app. All units can be controlled as a group for universal mode operation, or independently for temperature settings. Tenants benefit from even, comfortable temperatures and reliable conditioning.

“We’ve received great feedback on how quickly the units heat the building in the winter and cool it on warm days,” said Etheridge. “The tenants and building management have expressed they are happy with performance and speed.”

Tenants also realize lower utility bills. Patterson can track the efficiency of the systems by monitoring each apartment’s energy bills.

“Sometimes the bills are as low as $45 per month in the winter,” said Patterson. “Georgia isn’t the coldest place in the world, but we see temperatures in the high 20s and low 30s that definitely make tenants want to have their heat running.”

COMFORT INSIDE AND OUT

For Patterson, the right HVAC solution would be low impact for his tenants from an aesthetic, maintenance and operational sound level standpoint. He wanted to make sure that his confidence in the indoor comfort levels also translated to outdoor amenities for his tenants.

The apartments have access to private rooftop cupolas and walkout patios. While this feature has appeal to prospective tenants, Patterson was initially concerned about noise levels from the system’s outdoor units installed there. Those concerns were quickly squashed. With the units’ whisper quiet operation, they are barely audible at 58 dB(A).
