19.1 Bosch Experience Center at Serenbe
(BECS) Project
Just 30 miles south of Atlanta, Georgia, there is a vibrant
community known as Serenbe, an award-winning 1,000-
acre real estate and sustainable farming development.
This eco-conscious development is the community that
Bosch chose to partner with to show homeowners
Bosch geothermal and other sustainable home products.
Serenbe is nestled in the heart of 65,000 acres of forest,
now incorporated as the City of Chattahoochee Hills,
and protected by a development plan that preserves
70 percent of the area’s green space. Serenbe expertly
integrates nature, passion, creativity, and community
into the development. In the same way, Bosch is showing
homeowners how to combine green technologies to create
an integrated solution for their homes.
The rst Bosch Net Zero Home (Fig. 152) in the US
is at Serenbe, located at 10660 Serenbe Lane, and
demonstrates the integrated systems approach by
combining the following products:
f Geothermal heating and cooling system
f Heat pump water heater
f Solar photovoltaic system
f Energy efficient home appliances
f Controls

Just as Serenbe integrates different components into
its community’s development and lifestyle, Bosch has
integrated different technologies optimally in the Bosch
Net Zero home. The home combines sustainable and
energy ef cient technologies to rst minimize energy
consumption and second, generate electricity to meet or
exceed this small consumption. This systems approach
helps homeowners reduce their monthly utility bills while
protecting the environment.
The Bosch Net Zero Home is a 1,650 square-foot structure
and features a complete suite of Bosch technologies,
such as a geothermal heat pump heating and cooling
system equipped with the optional heat recovery package
(“desuperheater”) for domestic hot water production,
solar photovoltaic panels and an electric heat pump water
heater. Bosch desires to show homeowners that no one
technology is right for everyone, but that a homeowner
should consider which products work best for their home
and look at an integrated solution.
To maintain the home’s indoor temperature at a
comfortable level, a Bosch 3-ton geothermal heat pump
system (Fig. 153) is installed in the home (TA035-1HZC).
Designed and built domestically in Ft. Lauderdale, FL., the
technology literally provides American energy from right
under your feet for heating and air conditioning for the
home. Ground and water temperatures (thermal energy)
stay relatively constant throughout the year, allowing the
system to provide extremely ef cient heating or cooling all
year long in virtually any climate. In general, geothermal
systems allow for up to 70% savings and quiet operation
compared with conventional heating and cooling systems.
