Introduction

Over the past five to seven years, server infrastructure
has transformed from an invisible electricity consumer
into a significant source of low

grade heat. According to

the International Energy Agency, the total electricity
consumption of global data centers, excluding mining,
rose to 240

340 TWh in 2022, equivalent to

approximately 1

1.5% of global generation. Meanwhile,

telecommunications networks added another 260

360

TWh (IEA, 2023). Recognizing the resource potential of
such excess heat, regulators are shifting from voluntary
to mandatory recovery mechanisms: the new German
Energy Efficiency Act requires that all data centers

commissioned after 1 July 2026 deliver at least 10 % of

their thermal output to external heat networks, rising to

20 % from 2028 (Judge, 2023). Thus, rather than viewing

IT load solely as a cooling challenge, the industry is
increasingly treating it as a marketable thermal resource
to be integrated into existing building HVAC systems and
urban heating loops.

Practical benefits of this strategy are already

measurable. In Sweden’s capital, the

Open District

Heating scheme had connected two dozen IT sites by
2022 and annually extracts enough heat to warm around

30,000 modern apartments, reducing the network’s
specific emissions by 50 g CO₂ per kWh delivered

(European Commission, 2023). For HVAC designers, this
presents a stable source of medium-temperature heat
that can be easily incorporated via plate heat

exchangers and managed by the same IoT controllers

that govern the rest of the building’s engineering

systems.

Mining farms, in particular, offer exceptionally high
heat

flux density. At the network scale, this provides a

notable contribution: Bitcoin mining consumption was
estimated by the IEA to be 110 TWh in 2022, twenty
times the 2016 level (IEA, 2023). Such concentrated
boilers are well-suited for liquid cooling: immersion
baths or coolant loops can feed radiator circuits directly,
eliminating the need for high-lift heat pumps. A pilot in
Finland

s Satakunta region demonstrated that even a 2

MW installation can supply heat to approximately
11,000 residents via the local district heating system
(Gooding, 2024).

Thus, excess heat from IT equipment

especially crypto-

mining

ceases to be a passive byproduct and becomes

an active element in low-carbon building architecture.
The following sections will examine how to select the
appropriate integration scheme for incorporating heat
into existing HVAC loops and which IoT algorithms to
employ to balance computational load against heat
consumer requirements.

Materials and Methodology

This section is based on an analysis of 24 sources,
including academic studies, industry reports, pilot
project case studies, and regulatory documents. Among
the works reviewed were global data

center

consumption and heat

recovery potential assessments

(IEA, 2023), German regulatory requirements for heat
recovery (Judge, 2023) and the EU Energy Efficiency
Directive (Uptime Intelligence, 2023), Swedish and
Finnish project experiences (European Commission,
2023; Gooding, 2024), and technical descriptions of air
and immersion cooling equipment (BitMain, 2020; Zhou
et al., 2024). Additionally, retrofit guidelines for HVAC
systems (Simmons, 2020), specifications for OPC UA and
MQTT protocols (OPC Foundation, 2024; Dave, 2024),
and research on edge+cloud platforms for predictive
control (Petri et al., 2021) were examined.

The theoretical foundation comprised assessments of
mining-module heat-flux density and their integration
into heating loops. BitMain (2020) and Zhou et al. (2024)
indicate that, in practice, immersion cooling can deliver
heat at temperatures up to 60°C. It is, therefore,
attractive for direct connections with low-temperature
systems. Alfalaval (2024) and Profile IT Solutions (2025)
provide an assessment of three topologies

series-loop, and hybrid-grid

regarding their capital and

operational expenditures. Meanwhile, AMR (2025) and
Uptime Intelligence (2023) assessed the scalability of
solutions at the building and district levels.

Methodologically, the work combines four approaches.
First, a comparative analysis of heat

extraction

schemes: contrasting air and immersion cooling, as well
as the three architectural configurations by PUE and
heat

utilization

factor

(Alfalaval,

2024;

Profile

IT

Solutions, 2025). Second, it reviews the

regulations and industrial prescriptions in scope (Judge,
2023; Uptime Intelligence, 2023; European Commission,
2023) to synthesize criteria for ethical and safe
implementation. Third, a content analysis of pilot
cases

comprising the Swedish Open District Heating

scheme (European Commission, 2023) and the Finnish
Satakunta project (Gooding, 2024)

was conducted,

which returned heat return rates as well as impacts on

CO₂ emissions. The empirical experiment then runs

modeling using a digital twin of an HVAC system and the
LightGBM algorithm (Shi et al., 2024; Zanetti et al.,
2025), as well as thermal load forecasting models and
dynamic hash rate control strategies.

Besides the technical and regulatory reviews, the
current paper provided an economic analysis of
demand-response programs (Gracia, 2022; Riot
Platforms, 2025), a review of cyber-risk based on
incident statistics (Kaspersky, 2025), and results from a
study in chip degradation under conditions of thermal
stress (El-Sayed et al., 2012).

Results and Discussion

The integration architecture comprises five interrelated
layers, each of which must simultaneously satisfy
thermal

engineering,

electrical,

and

telemetry

constraints, ensuring that the computing node's excess
heat is converted into useful thermal power for the
building without compromising controllability. This
approach requires the coordinated selection of
equipment, protocols, and algorithms, since a change in
parameters at one layer immediately affects the
balances of the others.

At the computational

source level, GPU farms and

specialized ASIC racks are distinguished. The latter
achieves a record heat-flux density: a typical Bitmain S19
Pro at a hash rate of 110 TH/s consumes approximately
3.25 kW, all of which is dissipated as heat (Bitmain,
2020). In GPU solutions, the total load is distributed
among graphics cards and fans, reducing the specific

density but providing flexibility in frequency and voltage
control. For HVAC architects, the key factor is the
method of heat extraction. With air cooling, the specific
heat flux is limited; however, immersion cooling allows
the coolant to be delivered at temperatures of up to

60 °C, which is suitable for direct connection to low

-

temperature heating circuits (Zhou et al., 2024).

The subsequent chain begins with an HVAC retrofit. In
most existing facilities, it is expedient to install plate or
rotary heat exchangers, since they do not require a

complete overhaul of shafts and can recover over 80 %

of the sensible heat from exhaust air (Simmons, 2020).
Given that the fluid temperature from immersion baths
is significantly higher than the supply temperature, a
hydraulic insert into the existing heating loop and
re

tuning of VAV fans to maintain the required airflow in

the premises are sufficient.

To render the heat flux predictable, IoT infrastructure is
integrated into the loop: temperature, flow, and
vibration sensors transmit data via OPC UA or MQTT.
OPC UA defines the address space structure and mutual
device

authentication

mechanism,

ensuring

compatibility between the OT and IT layers (OPC
Foundation, 2024). In contrast, MQTT provides a
lightweight broker for event-driven messages and is
used when minimal latency or cellular-network
operation is required (Dave, 2024). A typical gateway
consolidates both protocols and translates the data into
a format understandable by the cloud or a local
processing server.

The next level hosts the management platform, where
an edge node stores second-level telemetry series,
constructs basic digital twins, and runs optimization
algorithms. Experiments on university campuses have
demonstrated that transitioning from purely cloud-
based analytics to a distributed edge and cloud
approach reduces the HVAC peak power draw through
more accurate predictive control (Petri et al., 2021). The
digital twin enables adj

ustment of the miners’ operating

point (partially disabling ASIC units or altering GPU
frequency) just enough to keep the heat

receiver

demand and the PUE limit in balance.

The final layer comprises interfaces with BMS and
SCADA. Most modern building systems support
BACnet/IP; the BACnet-BMS market is projected to
reach USD 17 billion by 2025, with further annual growth
of 3

4%, as shown in Fig. 1 (AMR, 2025).

Fig. 1. The BACnet Building Management System Market Size (AMR, 2025)

Modbus RTU or Modbus TCP is typically adequate for
local units. Climate equipment manufacturers currently
provide gateways that enable up to 100 Modbus devices
to be linked to a single KNX or BACnet bus without
requiring any additional programming (Trane, 2023).
Findings from an API-compatibility study revealed that
REST interfaces to BMS facilitate the integration of
external IoT platforms, thereby accelerating data
delivery to analytics by nearly a factor of two when
benchmarked

against

traditional

point-to-point

mapping (Yefi et al., 2024).

Together,

these

components

form

a

closed

technological loop in which the real

time reheated

output of the miners is converted into a controllable
energy resource for the building. At the same time, open
protocols reduce integration costs and ensure solution
scalability.

At the conceptual design stage, the choice of mining-
node connection scheme to the existing HVAC system is
determined by two variables

the share of heat that the

building can accept without reconstructing the heat-
exchange loop, and the temperature level of that heat.
The revised EU Energy Efficiency Directive prioritizes
economic recovery by obliging all data centers to
recover heat whenever possible, or to demonstrate
technical infeasibility regarding heat extraction. If a data
center does not consume extracted heat, details must
be provided on its use in external systems (Uptime
Intelligence, 2023). An example system is illustrated in
Fig. 2. This, therefore, brings three basic topologies that
can scale the solution from one building up to a district
heating network, preserving controllability via the IoT
loop.

Fig. 2. Data Center Waste Heat Export to District Heating Network (Uptime Intelligence, 2023)

Parallel, or by

pass, configuration is intended for

buildings where mining can supply no more than
one

third of the peak thermal load, thereby minimizing

intervention in the primary ventilation scheme. Hot air
or fluid from the racks is routed to a heat recovery unit
and then blended into the supply duct. When demand
drops, VAV dampers automatically open the bypass, and
the system reverts to normal operation. This approach
aligns well with regulations such as the German
Energy

Efficiency

Act, which sets a target threshold for

heat reuse of 30 % from 2024 and 40 % from 2027 for

new sites (Judge, 2023). Capital expenditures are limited
to the installation of a heat exchanger and a few sensors,
making the scheme attractive for rapidly deployable
edge nodes.

The sequential, or series

loop, model is employed when

the thermal output of mining is comparable to the
facility

s requirements and the temperature regime

permits operation without a heat pump. The fluid, which
extracts up to 200 kW from each rack via direct crystal
cooling, returns directly to the building

s hydraulic

circuit after passing through a plate heat exchanger
(Alfalaval, 2024). Mechanical cooling is scarcely utilized,
and energy savings for cooling reach 98

% compared to

traditional air cooling. To maintain this regime, an IoT

platform regulates miners’ hash rate via a predictive

thermal

balance model, synchronously adjusting pump

speeds and three

way valve positions.

When the heat source must serve multiple buildings, a
cascade or hybrid

grid scheme is preferred. In this

architecture, heat from the mining module is first stored
in a buffer accumulator, after which distribution stations
deliver it through a four

pipe network to residential and

commercial buildings. A Finnish pilot provides practical
validation: a 2-MW crypto center in the Satakunta
region supplies district heating for approximately 11,000
residents by feeding thermal energy into the municipal
network (Gooding, 2024). Load distribution among
multiple consumers reduces seasonal variability but
requires additional valves, commercial metering units,
and expanded IoT-SCADA functions to balance flows in
real-time.

The final solution is selected by comparing the building’s

specific thermal load, investment constraints, and
expected equipment lifecycle. At approximately 10 MW
capacities, the shift between air and immersion cooling,
as required for a Series-Loop and a Hybrid-Grid, reduces
capital expenditure by an average of 41% with lower
annual cooling energy expenses (Profile IT Solutions,
2025). However, as the share of recovered heat
increases, the backup removal systems for thermal
network failure become more expensive. This again

increases payback periods. Therefore, facilities with a
limited thermal share more frequently adopt the parallel
bypass, whereas new or extensively modernized
buildings with high thermal loads move to the sequential
scheme, and urban clusters with developed district
infrastructure utilize cascade networks. This matrix
approach

enables

flexible

integration

of

mining

generated heat into existing HVAC landscapes

while remaining within regulatory limits for energy
efficiency and emissions.

High

level algorithms link mining

rack telemetry,

building heating parameters, and energy

market price

signals into a unified decision

making model. At its core

is a predictive thermal balance: a LightGBM
gradient

boosting model trained on two seasons of

historical data achieved a mean absolute percentage
error of 6.2

% for 15

minute heat

load forecasts (Shi et

al., 2024), enabling the operator to reduce annual
cooling electricity consumption by 12

% without

compromising indoor climate (Zanetti et al., 2025).

When forecasts indicate a mismatch between the
potential heat output of computational modules and the
required heat supply, the system regulates the hash
rate. ERCOT practice in Texas has demonstrated the
scale of this maneuver: during extreme heat, industrial
miners synchronized shutdowns, freeing over 1,000
MW

i.e., more than 1 GW

for the grid, equivalent to

approximately 1% of the state’s peak load (Gracia,

2022).

Access to demand

response programs makes such

behavior economically attractive. For example, Riot
Platforms

June

2025 report shows that participation in

ERCOT and MISO schemes yielded USD

1.8

million in

demand

response credits and USD

3.8

million in price

credits

USD

5.6

million

in

total

reducing

the

weighted average cost of electricity to 3.4

 ¢

/kWh

(Riot

Platforms, 2025). These figures define the upper

bound of savings that a predictive controller can
incorporate into its objective function alongside PUE
and heat

utilization metrics.

Finally,

service

oriented

diagnostics

close

the

equipment sustainment loop. In a case study of a major
manufacturer implementing augmented reality for step-
by-step technician guidance, repair times decreased by
30% while error rates fell by 40%, directly improving
mining-cluster availability and reducing the risk of
unexpected thermal deficits (Fatfinger, 2024).

Together, predictive forecasting, dynamic hash-rate

adjustment,

integration

with

demand-response

programs, and service-oriented diagnostics form a self-
tuning cycle that maintains thermal and energy
efficiency at levels required by modern regulations and
business metrics.

The risk landscape of integrating mining installations
into HVAC circuits extends far beyond thermal

balance

calculations:

cryptocurrency

price

fluctuations,

hardware

failures,

regulatory

constraints,

and

cyberattacks can undermine the business case even in
flawless designs. Volatility is the primary and most
obvious threat. In 2022, Bitcoin lost 65

% year

on

year

amid the Terra

USD collapse and FTX bankruptcy

the

industry

s worst annual performance since 2018

(McCarthy, 2022). To mitigate such downturns,
operators tie mining regimes to thermal and grid signals:
when coin prices are low and heat demand is high, the
farm continues operating for the heat

network contract,

generating off

exchange revenue; when excess

electricity and rising coin prices occur, a boost mode
activates, selling hash rate to the market. Cash

flow gaps

are further insured by fixing part of profits in forward
electricity contracts and cryptocurrency collar options

a practice now employed by major public miners in
North America.

Technological risk manifests in two forms. Overheating
and thermal shock cycles accelerate chip degradation. A
server-reliability study found that for every 10°C above
21°C, the lifespan of electronic components is halved (El-
Sayed et al., 2012). Immersion cooling stabilizes crystal
temperature and acts as a humidity shield. Meanwhile,
dew-point and corrosion sensors are also integrated into
the IoT loop, along with the application of a selective
conformal lacquer to the circuit boards. At the policy
level, an N + 10% spare-rack rule allows equipment to be
worked on without removing it from the building's
thermal output.

Because mining modules generate heat continuously,
non-fulfillment of requirements is liable to be fined and
may also carry a suspension in operations. Risk can be
mitigated at the feasibility stage: a digital twin of the
HVAC scheme simulates at least three heat-demand
scenarios

normal, anomalously warm season, and

network-failure emergency

and demonstrates to

regulators the ability to dissipate power safely without
overheating. Additionally, an isolated dry

cooling circuit

is reserved and automatically engaged if the fluid
temperature exceeds permissible limits.

Cyber threats are among the critical factors. In Q4 2024

alone, Kaspersky ICS

CERT recorded 107 publicly

confirmed incidents in industrial networks, 50

% of

which involved ransomware and 12

% resulting in

production

line shutdowns (Kaspersky, 2025), with most

incidents occurring in the USA, as shown in Figure

3.

Fig. 3. Countries with the highest number of reported incidents (Kaspersky, 2025)

In mining

HVAC topologies, a breach of the OT segment

entails the simultaneous loss of hash rate and thermal
generation; therefore, segmentation according to an
east

west firewall principle and Zero Trust VPNs

between layers of IIoT gateways and the BMS becomes
a mandatory requirement. ASIC firmware is stored in a
repository with integrity verification, and critical PLCs
receive a unidirectional data

diode channel to SCADA,

preventing any reverse writing. These measures,
together with regular red

team attack simulations,

reduce intrusion detection time and limit damage to the
scope of an isolated segment.

Thus, financial, technological, regulatory, and cybernetic
risks jointly define the framework for integration
architecture. It enables a highly dispersed source to
become a vital component of low-carbon systems while
still operating, by implementing specific measures and
actions, ranging from investing in crypto to multiple
layers of OT safety.

Conclusion

This study will build a detailed model of how to fit mining
installations into existing HVAC systems with IoT control
at five related levels: starting from the computational
modules that produce heat, moving through retrofit

heat-exchange loops, including a telemetry network,
using an edge-plus-cloud management platform, and
finally ending with BMS/SCADA interfaces. The key
characteristics of various equipment types are
described

from high-density ASIC rigs dissipating up to

3.25 kW per device to flexible GPU farms

and the

benefits of immersion cooling in maintaining coolant
temperatures sufficient for direct connection to low-
temperature heating systems are demonstrated.
Meanwhile, the selection of recuperators and
adaptation of VAV fans in retrofit scenarios can achieve

up to 80 % recovery of sensible heat, minimizing capital

expenditures and the risk of interference with a

building’s primary engineering infrastructure.

Analysis of the three basic integration topologies

parallel (bypass), sequential (series-loop), and cascade
(hybrid-grid)

has shown that each is optimal under

specific conditions: the building’s recoverable thermal

-

load fraction, the coolant temperature level, and the
scale of the territorial network. The bypass
configuration is ideally suited for rapid deployment at
edge sites with moderate thermal output. The series-
loop delivers maximum energy savings on mechanical
cooling at coolant temperatures up to 60°C, and the
hybrid-grid enables solution scaling to district and

municipal networks with buffer accumulators and
complex flow distribution. IIoT gateways supporting OPC
UA and MQTT, integration into BACnet/IP and Modbus
loops, and the implementation of digital twins and
LightGBM predictive models ensure precise balancing

between miners’ computational loads and heat

-sink

demands.

It is attentive not just technically, but also economically,
regulatorily,

and

cybersecurity-wise:

from

the

fluctuations in cryptocurrency prices and hardware
failures to requirements under the Energy Efficiency Act
and threats in the OT segment. The self-tuning cycle
proposed

dynamic hash-rate adjustment inclusive,

demand-response

programs,

augmented

reality

assisted service diagnostics, and multi-layered OT
protection

ensures minimized unplanned disruption

and financial losses. Ultimately, the integration of excess
heat from mining installations emerges not as a
byproduct of IT infrastructure but as an active resource
for low-carbon buildings and urban thermal networks,
capable of enhancing overall energy efficiency and
making a meaningful contribution to CO2 emissions
reduction.
