Abstract:
This article analyzes the technical and
economic feasibility of integrating energy-efficient
solutions and renewable energy sources (RES) into
architectural design in Azerbaijan. The study begins by
examining the current state of Azerbaijan's energy
sector, which is heavily reliant on natural gas-fired
thermal power plants, despite having substantial solar
and wind energy potential. The primary aim is to
identify optimal strategies for designing energy-
efficient buildings in Azerbaijan, considering climatic
conditions, available technologies, and economic
factors. The methodology involves a multi-faceted
approach: a review of passive and active energy
efficiency strategies applicable to architectural design
(including
volumetric
planning,
natural
lighting/ventilation, thermal insulation, shading,
efficient HVAC, heat recovery, and Building
Management Systems (BMS)); an assessment of
Azerbaijan's solar and wind energy potential; and a
multi-criteria SWOT analysis. Results indicate a
significant, untapped potential for solar (23,000 MW)
and wind (3,000 MW onshore, 157 GW offshore)
energy in Azerbaijan. The SWOT analysis highlights the
strong government support and favorable climate as
major strengths, while acknowledging the current low
RES penetration and a shortage of skilled professionals
as weaknesses. Opportunities include declining global
RES technology costs and a growing demand for
"green" buildings. Threats include competition from
the established fossil fuel sector and potential climate
risks. The main conclusion is that integrating RES and
energy-efficient design is not only technically feasible
but also strategically vital for Azerbaijan's sustainable
development, energy security, and environmental

protection. Recommendations are formulated to
develop an effective strategy for RES integration,
focusing on supportive policies, capacity building,
financial incentives, and public awareness campaigns.
The findings contribute to the field of sustainable
architecture by providing a context-specific analysis
and practical guidance for architects, engineers, and
policymakers in Azerbaijan and similar regions
transitioning to a low-carbon energy future. The study's
limitations include the reliance on publicly available
data and the dynamic nature of energy policy, which
requires ongoing monitoring and adaptation of
strategies. The practical implications emphasize the
need for updated building codes, training programs,
and financial mechanisms to promote widespread
adoption of energy-efficient and RES-integrated
building designs.

Introduction:
Global climate change and the depletion
of fossil fuel reserves necessitate a transition to a
sustainable energy model. A key element of this model
is increasing energy efficiency and utilizing renewable
energy sources (RES) in the construction industry.
Buildings consume a significant portion of the world's
energy and produce a substantial volume of
greenhouse gas emissions. Therefore, reducing their
energy load and decarbonizing the construction sector
are
priority
tasks
for
achieving
sustainable
development goals. In this context, architectural design
takes on special significance, serving as a tool for
creating energy-efficient and environmentally friendly
buildings
capable
of
minimizing
negative
environmental impact. Fundamental decisions that
determine
a
building's
future
operational
characteristics, including its energy consumption,
emission levels, microclimate, and user comfort, are
made at the design stage. The application of passive
and active energy efficiency strategies, as well as the
skillful integration of RES into a building's architectural
concept, can significantly reduce its environmental
footprint and provide long-term economic benefits.
Accordingly, this study is devoted to analyzing the
technical and economic indicators of integrating
energy-efficient solutions and RES into architectural
design. Its goal is to identify optimal building design
strategies, taking into account climatic conditions,
available technologies, and economic factors.
Achieving this goal involves several tasks, including
analyzing modern methods for improving building
energy efficiency, assessing the potential of using
various RES in architecture, developing a methodology
for the technical and economic justification of choosing
energy-efficient solutions and RES, and identifying
barriers and prospects for the development of
sustainable construction. The study will consider
indicators such as building energy consumption, life
cycle cost, payback period of investments in energy-
efficient technologies and RES, and environmental
indicators reflecting the building's impact on the
environment.
This study implicitly investigates several core
hypotheses related to the integration of renewable
energy sources (RES) and energy-efficient design in the
Azerbaijani construction sector. Primarily, it examines
the technical feasibility hypothesis, positing that the
country's climatic conditions and available technologies
permit the effective incorporation of RES (specifically
solar and wind) and advanced energy-efficiency
strategies into building design, leading to substantial
reductions in energy consumption. Concurrently, the
economic viability hypothesis is tested, asserting that
the long-term financial benefits of such integration,
including favorable payback periods and positive
returns on investment, outweigh potential higher initial
costs,
rendering
it
economically
justifiable.
Furthermore, the environmental benefit hypothesis is
evaluated, proposing that RES-integrated, energy-
efficient buildings will demonstrate a significantly
reduced environmental footprint, quantified by lower
greenhouse gas emissions and resource consumption,
compared to conventional building designs. A strategic
advantage hypothesis is also considered, suggesting
that a multifaceted strategy encompassing policy
support, financial incentives, and capacity-building
initiatives can effectively mitigate identified barriers
and foster widespread adoption. Finally the study tests
if passive design strategies will demonstrate a greater
return on investment when compared to active design
strategies.
Therefore,
overall,
the
research
operationalizes these hypotheses to assess the
technical
possibility,
economic
justification,
environmental benefit, and strategic achievability of a
paradigm shift towards sustainable building practices in
Azerbaijan.
The theoretical significance of the study lies in
developing scientific understanding of the relationship
between architectural design, energy efficiency, and
RES integration. The research results will supplement
the theoretical base in the field of sustainable
construction and architecture, contributing to the

formation of an integrated approach to building design,
taking into account energy, environmental, and
economic aspects. The methods developed within the
study for assessing technical and economic indicators
can be used for further scientific research in this area.
The study also contributes to the development of
architectural design theory, expanding its toolkit by
integrating the principles of energy efficiency and
sustainable development.
The practical significance is determined by the
possibility of applying the results obtained in real
design practice. The developed recommendations for
optimizing architectural solutions and integrating RES
will allow architects and engineers to design energy-
efficient and environmentally friendly buildings,
reducing their negative impact on the environment.
The application of the proposed methods of technical
and economic analysis will make it possible to
reasonably choose the most effective solutions, taking
into account the specifics of the project and climatic
conditions. The results of the study can be used in the
development
of
regulatory
and
technical
documentation and educational programs in the field
of sustainable construction. In addition, the study
contributes to raising public awareness of the
importance of energy efficiency and the use of RES in
construction.
MATERIALS AND METHODS
This study is based on an integrated approach,
combining qualitative and quantitative analysis
methods. Various sources of information were used for
data collection, including official reports from the
Ministry of Energy of the Republic of Azerbaijan,
publications from international organizations (IRENA,
IEA), scientific articles, industry reviews, and data from
open sources. Particular attention was paid to the
analysis of statistical information on electricity
production and consumption, the structure of installed
power plant capacity, the dynamics of RES
development, as well as data on climatic conditions and
the geographical location of Azerbaijan. Data on global
trends in the development of "green" energy, including
the dynamics of the levelized cost of electricity (LCOE)
for various types of RES, were used to assess the
potential of RES and their economic feasibility.
SWOT analysis and multi-criteria assessment methods
were used to analyze the technical and economic
feasibility of integrating RES into architectural design.
The SWOT analysis made it possible to identify
strengths, weaknesses, opportunities, and threats
associated with the development of RES in Azerbaijan.
Multi-criteria assessment was used to determine the
significance of various factors influencing the
effectiveness of RES integration in buildings, such as
resource potential, technological readiness, regulatory
framework,
investment
climate,
and
social
acceptability. An expert assessment of the impact and
probability of implementation was carried out for each
factor.
In addition, the study used methods of comparative
analysis to examine the experience of other countries
in the field of RES integration in architecture, as well as
forecasting methods to assess the prospects for the
development of "green" energy in Azerbaijan. The
results of the study are presented in the form of tables
and analytical conclusions, which allow for the
formulation
of
specific
recommendations
for
optimizing architectural solutions and increasing the
efficiency of RES use in the construction industry. The
integrated approach used in the study made it possible
to obtain a comprehensive assessment of the feasibility
of integrating RES into architectural design in
Azerbaijan and to develop practical recommendations
for its implementation.
RESULTS
1.Theoretical Foundations of Energy Efficiency in
Architectural Design
Energy efficiency in architectural design represents a
comprehensive approach aimed at minimizing a
building's energy consumption without compromising
comfort [1]. This approach is becoming particularly
relevant in light of growing challenges in the energy
sector that affect the environment, energy security,
and economic well-being [1]. Buildings, being a key
focus for improving energy efficiency, consume a
significant portion of energy
—
according to data from
2024, buildings in Azerbaijan consume 33.5% of the
country's total energy, which exceeds the global
average of 30% [2]. If industry and other sectors are
included in this figure, the share reaches 50% [2].
Despite the active development of Azerbaijan's energy
infrastructure between 2004 and 2014, including the
construction of 17 power plants, over 10,000 km of
power transmission lines, and more than 1,500
substations, increasing the total power generation
capacity by 2,300 MW [3], building energy consumption
remains high. Azerbaijan has been fully self-sufficient in
electricity since 2021 [4], but the majority (94%) is
produced by thermal power plants (TPPs) operating on
natural gas, highlighting the importance of developing
renewable energy sources in construction, which,
together with hydropower plants, account for only 6%
The American Journal of Applied Sciences

[5; 6]. In 2019, the installed capacity of power plants in
Azerbaijan was 7,642 MW, of which only 101 MW was
attributed to wind and solar power plants [7], indicating
significant potential for their further development in
the architectural sector. The growth in electricity
production from 25,229 million kWh in 2018 to
29,004.3 million kWh in 2022 [8; 9], as well as the
significant volume of electricity exports (2,997.5 million
kWh in 2022) [27], also demonstrate the development
of the energy sector, but simultaneously emphasize the
need for more efficient energy use in buildings to
reduce the overall load on the energy system and
decrease the environmental footprint. Therefore, the
integration of passive and active energy efficiency
strategies at the earliest stages of design is becoming
an integral part of the modern architectural process
—
this not only reduces energy consumption and CO2
emissions but also contributes to achieving sustainable
development goals.
Passive energy efficiency strategies, based on the
principles of bioclimatic architecture, represent a set of
interrelated design solutions aimed at creating a
comfortable and energy-efficient environment [18; 19]
(Table 1). These strategies involve the active interaction
of the building with the environment, using natural
resources
—
solar radiation, wind, and geothermal
energy
—
as the primary energy sources to maintain an
optimal microclimate and minimize negative impacts
[18; 19].
When applying passive strategies, optimizing space-
planning solutions becomes critically important, as the
geometry and orientation of the building significantly
influence its energy balance [20]. Taking into account
the azimuth and altitude of the sun allows not only for
maximizing passive solar gains during the cold season,
reducing the need for active heating, but also for
minimizing overheating during the summer, reducing
the load on cooling systems and, consequently, energy
consumption [20]. Choosing compact building shapes
with a low surface area-to-volume ratio (S/V) minimizes
heat loss through transmission, as confirmed by
building energy consumption modeling results using
specialized software (e.g., EnergyPlus, TRNSYS) [21; 22].
Moreover, detailed analysis of solar geometry and
shadow masks using dynamic modeling tools (e.g.,
Ecotect, DesignBuilder) allows not only for assessing
the amount of solar radiation reaching different
building surfaces throughout the year but also for
optimizing the building's placement on the site,
considering surrounding buildings and landscape, as
well as developing effective and aesthetically
integrated architectural shading strategies [23; 24].
Another important aspect of passive architecture is the
strategic design of window openings and interior
spaces to maximize the use of diffuse and reflected
daylight [25; 26]. This type of design not only
significantly reduces energy consumption for artificial
lighting but also creates a more comfortable and
productive visual environment for building occupants,
positively impacting their psychophysiological state.
Calculating the daylight factor (DF) and analyzing
daylight autonomy using professional lighting design
software (e.g., DIALux, Relux) allows for a quantitative
assessment
of
daylighting
effectiveness
and
optimization of the size, shape, and placement of
window openings [25; 26]. Furthermore, the
application of advanced lighting solutions, such as light
pipes, light wells, atriums, and systems with variable
reflective surface geometry, allows not only for
efficient distribution of daylight deep into the room but
also for the creation of unique architectural and artistic
effects [25; 26]. Moreover, integrating natural and
artificial lighting systems using light sensors, photocells,
and intelligent control systems ensures dynamic
adaptation of artificial lighting to changing natural
lighting conditions, achieving significant energy savings
[25; 26].
Finally, natural ventilation, based on the use of natural
forces
—
wind and thermal convection
—
represents an
efficient and energy-saving alternative to mechanical
ventilation systems, contributing to the creation of a
healthy and comfortable indoor microclimate [27].
Various natural ventilation strategies, such as cross-
ventilation, stack ventilation, night ventilation, and
their combinations, can be applied considering specific
climatic conditions, architectural features of the
building, and the functional purpose of the spaces [27].
To ensure the effective operation of natural ventilation
systems, it is necessary to perform detailed airflow
calculations considering local climate data and to use
modern computational fluid dynamics (CFD) modeling
methods to analyze and optimize airflow within the
building. At the same time, to create a truly
comfortable and healthy indoor environment, it is
important to consider not only quantitative airflow
rates but also qualitative microclimate parameters
—
acoustic comfort, insect protection, and draft
prevention.

Unlike passive strategies, which focus on utilizing
natural resources, active strategies involve the
application of engineering systems that allow for
precise control of microclimate parameters and
adaptation of equipment operation to changing
conditions [28]. One of the key components of active
strategies is high-efficiency heating, ventilation, and air
conditioning (HVAC) systems [29]. The use of heat
pumps with a high Seasonal Coefficient of Performance
(SCOP) and Coefficient of Performance (COP) allows for
a significant reduction in energy consumption for
heating and cooling compared to traditional systems
[30]. Geothermal systems with vertical or horizontal
heat exchangers utilize the stable ground temperature
for efficient building heating and cooling, minimizing
energy consumption from external sources [31]. Solar
collectors for water and air heating enable the use of
renewable solar energy, reducing dependence on fossil
fuels [32]. Variable Refrigerant Volume/Variable
Refrigerant Flow (VRV/VRF) systems with heat recovery
and individual temperature control provide a high level
of comfort and flexibility in managing the microclimate
in individual rooms [33]. Additionally, radiant heating
and cooling systems integrated into building structures
provide even distribution of heat and cold, increasing
energy efficiency and comfort [34].
Heat recovery is an important component of active
energy efficiency strategies, allowing for the utilization
of heat from exhaust air to preheat incoming fresh air,
thereby reducing heat losses during ventilation [35].
Different types of heat exchangers
—
plate, rotary, run-
around coil
—
provide varying heat recovery
efficiencies and are selected based on specific project
conditions [35]. The application of heat pipes and
thermal energy storage materials allows for a further
increase in heat recovery efficiency and a reduction in
energy consumption for ventilation, integrating with
HVAC systems to create an energy-efficient and
comfortable microclimate [35]. Calculating heat
recovery efficiency allows for optimizing system
operation and achieving maximum energy efficiency
[35].
Intelligent control and monitoring of all building
engineering systems are carried out using a Building
Management System (BMS) [36]. Integrated building

automation systems based on the Internet of Things
(IoT) collect and analyze data from various sensors
(temperature, humidity, CO2, illuminance) and provide
adaptive control of HVAC, lighting, and shading systems
in real-time [36]. Predictive energy consumption
modeling allows for optimizing system operation,
taking into account predicted changes in external
conditions and user needs. The BMS not only optimizes
energy consumption but also increases the comfort and
productivity of building occupants, as well as reduces
operating costs by preventing emergencies and
optimizing equipment operating modes.
Finally, energy-efficient lighting is based on the use of
high-efficiency light sources, such as light-emitting
diode (LED) lamps with high luminous efficacy, and
intelligent control systems that minimize energy
consumption for lighting [37]. Lighting control systems
with occupancy sensors, daylight sensors, and dimming
control provide automatic switching on and off of lights
and adaptation of illuminance levels to changing
conditions. Dynamic lighting, adapting to natural
lighting and human circadian rhythms, enhances
comfort and productivity. Integration of the lighting
system with the BMS allows for optimizing energy
consumption and creating an intelligent lighting control
system in the building.
DISCUSSION
Analysis of the Techno-economic Feasibility of
integrating energy-efficient solutions and renewable
energy sources into architectural design in Azerbaijan
The integration of energy-efficient solutions and
renewable energy sources (RES) into architectural
design in Azerbaijan represents not just a promising
direction, but a strategic necessity, driven both by the
significant, yet unrealized, potential of solar and wind
energy and by the global drive towards decarbonization
and economic diversification. Currently, the Azerbaijani
energy system is characterized by the dominance of
natural gas-fired thermal power plants (TPPs).
According to the report of the Ministry of Energy of the
Republic of Azerbaijan for 2022 [9], TPPs generated
27,059.1 million kWh, which accounts for more than
90% of the total electricity generation. The achieved
energy self-sufficiency is undoubtedly an important
achievement, but dependence on fossil fuels creates
environmental risks associated with greenhouse gas
emissions and other pollutants, and limits the long-
term sustainability of the energy sector in the context
of a changing climate and the global energy transition.
The transition to RES, particularly solar and wind
energy, is fully in line with global decarbonization
trends,
contributes
to
meeting
international
commitments to reduce greenhouse gas emissions, and
reduces dependence on limited natural gas reserves.
Azerbaijan possesses exceptional solar energy
potential, estimated at 23,000 MW [10], which is
comparable to the installed capacity of all the country's
power plants. The wind energy potential is also very
significant: 3,000 MW onshore and a colossal 157 GW
in the Azerbaijani sector of the Caspian Sea [11].
Effective utilization of this potential can fundamentally
transform the country's energy landscape, providing
clean and sustainable electricity generation.

The economic feasibility of integrating RES into
architecture is determined by a complex set of factors,
among which the key ones are the levelized cost of
electricity (LCOE), return on investment (ROI), the
availability of government support, and access to
financing. The global decline in the cost of solar panel
and wind turbine production technologies observed in
recent years makes RES increasingly competitive with
traditional TPPs. According to data from the
International Renewable Energy Agency (IRENA), the
LCOE for solar photovoltaic energy decreased by 85%
from 2010 to 2020, and for onshore wind energy
—
by
56% over the same period [12]. However, to assess the
economic efficiency of RES projects in Azerbaijan, it is
necessary to conduct a detailed LCOE calculation,
taking into account local conditions, such as the cost of
equipment and its delivery, installation work, operating
expenses, financing rates, access to networks, and the
availability of necessary infrastructure. Comparing the
obtained LCOE with the current electricity tariffs for
end consumers and industrial enterprises will make it
possible to determine the economic efficiency of
projects and the attractiveness of investments in
"green" energy.
The technical integration of RES into architectural
projects is a complex and multifaceted process that
requires careful analysis, planning, and the application
of
modern
technologies.
Building-integrated
photovoltaics (BIPV), solar thermal collectors for water
heating, and small wind turbines can be harmoniously
integrated into building design, providing electricity
and heat generation directly at the point of
consumption. During design, it is necessary to consider
many factors influencing the effectiveness of RES:
building orientation to the cardinal directions, the angle
of inclination of the roof or facade, shading from
surrounding buildings and trees, the availability of free
space for equipment placement, wind conditions, and
the intensity of solar radiation in the given area. To
ensure an uninterrupted energy supply, especially
during periods of low insolation or weak wind, it is
necessary to provide for energy storage systems, such
as lithium-ion or flow batteries. In addition, it is
important to ensure the compatibility of RES with the
existing building energy system, provide for monitoring
and control systems, and train personnel in the
operation and maintenance of new equipment.
Azerbaijan's favorable climatic conditions and
advantageous geographical location create excellent
preconditions for the widespread use of RES. The large
number of sunny days per year, characteristic of most
of the country, ensures high efficiency of solar power
plants. Significant wind potential, especially in the
coastal areas of the Caspian Sea and on the Absheron
Peninsula, opens up broad opportunities for the
development of wind energy. Azerbaijan's geographical
location allows for considering the export of "green"

Georgia, Russia, and Iran, which creates additional
economic incentives for the development of RES and
contributes
to
strengthening
regional
energy
cooperation. One example of such cooperation is the
project to export electricity via a submarine cable along
the bottom of the Black Sea to Romania and then to
Europe [13], which will allow Azerbaijan to become an
important player in the European "green" energy
market.
The development of RES in Azerbaijan is unthinkable
without the creation of an appropriate regulatory and
legal framework and the implementation of an active
state policy aimed at stimulating investment in this
sector. Clear and transparent rules for connecting RES
to the energy system, simplified procedures for
obtaining permits for the construction and operation of
RES facilities, mechanisms to support producers of
"green" energy, such as "green" tariffs, tax incentives,
and subsidies, as well as programs to improve energy
efficiency in construction, for example, the
introduction of "green" building standards and energy
certification of buildings, are necessary. One example
of successful government support is the construction of
the Shafag solar power plant with a capacity of 240 MW
with the participation of BP [14], which demonstrates
the attractiveness of the Azerbaijani RES market for
large international investors.
The integration of RES into architecture has not only
economic and environmental but also important social
consequences. The creation of new jobs in the
renewable energy sector, the reduction of dependence
on energy resource imports, the increase in energy
security, and the improvement of the environmental
situation positively affect the quality of life of the
population and contribute to the sustainable
development of the country. Informing the public
about the benefits of RES, increasing the level of
environmental literacy, and conducting educational
programs contribute to the formation of positive public
opinion and support for projects in the field of "green"
energy.
To assess the prospects for the integration of
renewable energy sources (RES) into architectural
design in Azerbaijan, a multi-criteria SWOT analysis was
also carried out (Table 4). This analysis made it possible
to comprehensively study the current situation and
identify the key factors influencing the development of
RES in the country. As part of the SWOT analysis,
strengths, weaknesses, opportunities, and threats
associated with the integration of RES into architecture
were assessed. Each factor was evaluated according to
two criteria: impact on RES development (on a scale of
1 to 5, where 1 is minimal impact, 5 is maximum impact)
and the probability of its realization (also on a scale of
1 to 5, where 1 is low probability, 5 is high probability).
The multiplication of these ratings gave a weighted
score reflecting the significance of each factor. Among
the strengths, the high potential of RES in Azerbaijan,
due to favorable natural and climatic conditions, as well
as active government support for the development of
"green" energy, were highlighted. As weaknesses, the
low current share of RES in the overall energy balance
and the lack of qualified personnel in this area were
noted. Opportunities included the declining cost of RES
technologies in the global market and the growing
demand for "green" buildings, and threats included
competition from traditional energy based on fossil
fuels and potential climate risks.

The SWOT analysis identified key areas for developing
renewable energy sources in Azerbaijan and integrating
them into architecture. Developing a long-term
strategy that includes specific goals, such as achieving a
30% share of RES in the energy balance by 2030 [15],
clear financing mechanisms, government support
measures and investment incentives, and international
cooperation, will allow for the effective use of existing
potential and ensure the sustainable development of
the energy sector. A phased transition to "green"
energy, starting with pilot projects and gradually
increasing the share of RES, will minimize risks, adapt
technologies to local conditions, and ensure a smooth
transition to a new energy model. Clear examples of
such projects are the construction of the 240 MW Khizi-
Absheron wind power plant [16] and the cascade of
hydroelectric power plants on the Okhchuchay River
[29], which demonstrate the practical implementation
of the RES development strategy in Azerbaijan. In
addition, an important direction is the modernization of
the existing energy infrastructure, increasing its
efficiency, and integrating it with new RES facilities.
CONCLUSION
In conclusion, the conducted research confirms the
high feasibility of integrating energy-efficient solutions
and RES into architectural design in Azerbaijan. The
analysis showed the presence of significant potential
for the development of solar and wind energy in the
country, which opens up wide opportunities for
reducing dependence on traditional energy sources
based on fossil fuels and reducing negative
environmental impacts. The identified strengths, such
as favorable climatic conditions, government support
for RES development, and the potential for exporting
"green" energy, create a solid foundation for the
successful implementation of a strategy for
transitioning to a sustainable energy model. However,
realizing this potential requires overcoming a number
of challenges related to the need to develop
appropriate infrastructure, train qualified personnel,
and attract investment.
The SWOT analysis revealed both opportunities,
related to the declining cost of RES technologies and
The American Journal of Applied Sciences

the growing demand for "green" buildings, and threats,
caused by competition from traditional energy and
potential climate risks. For the successful integration of
RES into architectural design, it is necessary to develop
a comprehensive strategy that takes into account all
identified factors and provides for measures to
neutralize or utilize them. Particular attention should
be paid to the development of the regulatory and legal
framework, the improvement of the system for
financing RES projects, and raising public awareness of
the benefits of "green" energy.
Thus, the integration of energy-efficient solutions and
RES into architectural design is a strategically important
direction for Azerbaijan, contributing to the sustainable
development of the country, reducing dependence on
fossil fuels, and improving the environmental situation.
Further research in this area should be aimed at
developing specific methodologies and tools for
assessing the technical and economic efficiency of RES
projects in buildings, as well as creating favorable
conditions for their widespread implementation in
design and construction practice. This will allow
Azerbaijan not only to effectively use its significant RES
potential but also to become a leader in the region in
the field of sustainable construction.
