Opened in January 2004, Brentwood is a 35,100-square-foot,
29-unit Residential Care Apartment Complex (RCAC) located in Rice
Lake, Wis. (pop. 8,500). Founded in 1864 on the site of a Menomonie
Indian village and a wild rice bed, Rice Lake is the largest
primarily retail community between Eau Claire (60 miles south),
Superior/Duluth (100 miles north), and Minneapolis/St. Paul (100
Created and owned by David and Diana Barta (Brentwood Senior
Communities, LLC), Brentwood may be the only assisted living
facility in the state with a concrete storm shelter (8-inch-thick
walls for the occasional tornado) which also serves as the facility
Designed by Rice Lake Architect DavidCramer, AIA, the current
facility occupies a "footprint" of approximately five acres out of
the total property of 32 acres, "with possible future expansion in
mind," according to Barta. The large commercial kitchen was
designed with future expansion as a possibility. Brentwood has a
staff of 16 full and part-time employees.
Brentwood HVAC System
In Brentwood's early design/planning phase, an old friend, Ervin
Dirks, Dirks Heating and Cooling, Barron, Wis. introduced Barta to
CITY MULTI® Variable Refrigerant Flow Zoning (VRFZ) systems, the
first (and only) simultaneous cooling and heating modular zoning
system in the United States, designed and manufactured by
Mitsubishi Electric HVAC.
Perfect for assisted living and long- term care facilities, Dirks
described a sophisticated, "smart" HVAC system that could provide
"whisper-quiet" personalized comfort controls in each guest room,
with a high efficiency zoning system that supplies up to 16 rooms
from one outdoor compressor. "I was attracted to CITY MULTI's
advanced heat pump INVERTER technology, efficiency, flexibility,
simultaneous cooling and heating, separate controls,
super-efficient heat pumps, and the prospects of long- term
savings," Barta said.
A Perfect Solution for Brentwood
Barta envisions the joys of the exact amount of cooling or heating
required by each zone, variable speed compressors for precise
comfort control, a constant and comfortable indoor environment, LCD
remote control for each unit, considerable cost savings and the
benefits of giving his guests their very own climate control.
Dirks Heating and Cooling installed two identical CITY MULTI
R2-Series VRFZ systems at Brentwood. Each 100,000 Btu/h outdoor
unit delivers refrigerant for cooling or heating to 14
ceiling-concealed ducted units. Mitsubishi Electric's heat pump
INVERTER technology varies the speed of the compressor in the
outdoor unit to match the load requirements in each interior space.
So, the system operates only at levels needed to maintain a
constant and comfortable indoor environment. High-efficiency
boilers have been added to provide heat when the Wisconsin winters
plunge to zero and below. CITY MULTI's advanced technology enables
the Brentwood facility to use these boilers less frequently,
providing management with considerable cost savings.
Thusfar, Barta says he is impressed with the ease and low costs of
the VRFZ system's installation. And he is looking forward to the
reduced operating costs made possible by the INVERTER- driven
technology which has the ability to cool one room and heat another
at the same time.
