Air conditioning systems
Air conditioning systems account for
almost 50% of the energy consumption
of a modern hospital, therefore it is
important to go after a more efficient
technology for our buildings.
At Rede D'Or São Luiz, we have taken up
a cold water production center (CAG, in
Portuguese), comprised by several water
chillers and fan coils (equipment that
filter and cool the air in the room).
Efficient and low-noise equipment were
particularly chosen to make up this
cooling system. We prefer air-cooled
chillers with a system to gradually
reduce the compressor's speed, for
instance, because they offer maximum
performance during long hours of
operation. The efficiency increase with
this equipment is estimated at 30% as
well as the reduction in environmental
footprint due to lower greenhouse gas
(GHG) emissions.
Wholesale Energy Market /
Solar Energy
Rede D' Or São Luiz subscribes to the
Wholesale Energy Market in order to
develop a sustainable management
strategy, since the relocation allows the
company to purchase its energy from
renewable sources, therefore, reducing
its environmental impact.
This initiative began in 2019, with São
Lucas (SE) and UDI (MA) hospitals and
continued throughout 2020 and 2021
with Perinatal Barra and Laranjeiras
(RJ), Santa Cruz (PR), Aliança (BA),
São Carlos (CE), Balbino (RJ), Biocor
(MG), Nossa Senhora das Neves (PB)
and Novo Atibaia (SP) hospitals. In 2021,
Rede D' Or São Luiz began to relocate
21 hospital units (25 measurement
points), which corresponds to an
average of 12.89MW incentivized energy
already contracted.
Currently, 32 units are in the wholesale
energy market and 4 units under the
relocation process, expected to be
completed in 2022.
The Wholesale Energy Market is a
segment of the energy sector in which
energy is purchased and sold through
bilateral agreements under freely
negotiated conditions. In the captive
market, on the other hand, energy is
supplied by the distributors and not
directly by the energy generator. The
market's trade rules and procedures are
defined by the Electric Energy Trading
Chamber (CCEE, in Portuguese). It is
a competitive trading environment, in
which consumers classified as "free" can
purchase energy as an alternative to the
supply from the local concessionaire.
To join this market, consumers need to

comply with the requirements set forth
by law.
In 2022, we will have 36 units in the
Wholesale Energy Market (average of
18.856 MW), with the addition of four
more units (Quinta D'Or - Main Building
and Annexes, Centro Médico Caxias
D'Or and São Marcos). This means we
will have almost 50% of Rede D'Or São
Luiz hospital units under this model,
with presence in the states of Rio de
Janeiro, São Paulo, Pernambuco, Bahia,
Maranhão, Minas Gerais, Sergipe, Ceará,
Paraná and Paraíba.
