Benefits of the use of thermal insulation in a naturally ventilated residenti...IJERA Editor
The use of thermal insulation is not a common practice in civil construction in Brazil. The national standard for
thermal performance and the energy efficiency labeling program do not require the use of thermal insulation in
the building envelope, even for the hottest and for the coldest regions of the country. Brazil has a temperate
climate region that covers 7.2% of its territory and contains important and populous cities. This paper explores
the benefits of the use of thermal insulation in dwellings located in that climate. A heat balance analysis was
conducted in the computational model of a naturally ventilated single-family residential building. The simulation
task was carried out in the EnergyPlus software with the use of weather files of three cities, classified as
temperate climates. The main sources of heat transfer through the building envelope were identified and
subjected to a sensitivity analysis, seeking for the building performance optimization. Simulation results shows
that thermal insulation can be applied on building walls, roof and floor, with benefits measured as a reduction in
the heating degree hours along the year. Increase in cooling degree hours during the summer could be overcome
with strategies to control the solar heat gain on windows

- Existing buildings already have embodied energy from initial construction materials. Reuse avoids adding new embodied energy of newly extracted and manufactured materials.
- Many traditional rural buildings employed passive design strategies well-suited to the local climate, like thick stone walls providing high thermal mass.
- Reuse can reduce a building's total energy needs over its lifetime by 14-30% compared to

The document concludes that applying these passive cooling strategies can significantly decrease energy demands, lower cooling loads and provide a more sustainable and comfortable living environment.
Comparison of Intelligent Façade’s Energy Efficiency in Hot and Humid Climate...paperpublications3
Abstract: Energy conservation and sustainable designs are very hot topics in the world today. Currently architects and building designers greatly influence the level of energy conservation in the world, since buildings are the highest energy consumers. Generally the use of passive heating and cooling systems has had a huge impact in energy conservation, especially in the warm and humid climate. This research will therefore focus on comparing intelligent skins (case in point: double skin façade), which are adaptive and/or responsive to the surrounding environment and how efficient they can be in their energy conservation on the principles of passive designs for warm and humid climate such as natural ventilation and free air movement, providing ample shading systems, glare control and so on.

Individuals and organizations conserve energy to reduce costs and increase economic security, while industrial and commercial users aim to maximize profits. Passive solar building design techniques allow buildings to collect, store, and distribute solar energy for heating and cooling. Responsibility for energy conservation in the UK falls primarily to the Department of Energy and Climate Change.

This study analyzes energy saving measures for housing blocks in Madrid, Spain. It evaluates adding insulation to exterior walls and replacing windows. Adding 0.04-0.06m of insulation to exterior walls provides the most savings over time. Replacing windows with double glazing also significantly reduces heat loss. Small, targeted interventions tailored to individual buildings can achieve high energy savings compared to one-size-fits-all regulations. The paper concludes these measures should be considered as alternatives in the Spanish building code to better balance energy efficiency and costs.
Cool roofs and pavements can significantly reduce energy consumption and costs for cooling buildings. Applying highly reflective materials to roofs and pavements decreases their surface temperatures, reducing the transfer of heat into buildings and the ambient air. Several pilot projects showed energy savings of up to 98% for cooling through the use of cool materials. Case studies in Greece and Jamaica demonstrated that cool roofs reduced surface temperatures by around 10°C and cooling energy demand by 17-22%. The materials provide a low-cost solution to improving thermal comfort and energy efficiency, especially in hot climates.
HIGH TEMERATURE THERMAL ENERGY STOARAGE SYSTEM APPLICATIONSijiert bestjournal
Thermal energy storage (TES) includes a number of d ifferent technologies. Thermal energy can be stored at temperatures from -40�C to more than 400�C as sensi ble heat,latent heat and chemical energy (i.e. the rmo- chemical energy storage) using chemical reactions. Thermal energy storage in the form of sensible heat is based on the specific heat of a storage medium,whi ch is usually kept in storage tanks with high therm al insulation. The most popular and commercial heat st orage medium is water,which has a number of reside ntial and industrial applications. Underground storage of sensible heat in both liquid and solid media is al so used for typically large-scale applications. However,TES sy stems based on sensible heat storage offer a storag e capacity that is limited by the specific heat of th e storage medium. Phase change materials (PCMs) can offer a higher storage capacity that is associated with the latent heat of the phase change. PCMs also enable a target- oriented discharging temperature that is set by the constant temperature of the phase change. Thermo-c hemical storage (TCS) can offer even higher storage capacit ies. Thermo-chemical reactions (e.g. adsorption or the adhesion of a substance to the surface of another s olid or liquid) can be used to accumulate and disch arge heat and cold on demand (also regulating humidity) in a variety of applications using different chemical re actants.

This document analyzes bioclimatic design strategies in vernacular architecture from regions with extreme climates in Spain. It identifies 10 such regions based on climate indices, then uses Givoni's bioclimatic charts to determine appropriate strategies. For hot summer regions, these include high thermal mass, night ventilation, natural ventilation and solar protection. For cold winter regions, strategies minimize heat loss and maximize solar gains. The analysis of traditional architecture found techniques like thick walls, small openings, local materials and adapted living practices that responded well to local climates and can inspire modern bioclimatic design.
This study evaluated cost-effective strategies to improve the energy efficiency of residential buildings in Jordan. It analyzed different energy conservation measures for buildings in three climate regions, including insulation upgrades, solar shading, double glazing windows, and HVAC and lighting system improvements. The results showed that upgrading HVAC systems and installing additional wall insulation provided the most savings. A package of upgrades including more efficient HVAC, windows, lighting, and insulation could reduce energy consumption by up to 47.6% with a payback period of 9.3 years, making it a cost-effective approach to designing more energy efficient homes.

The engineering structures of the traditional rural roads are one of the elements with greater visual impact can get to cause over the landscape. As a possible way of minimizing this impact, it`s advised to adequate the design of the new constructions to the traditional types of each region. However, the small bridges built by the “popular engineering” have been disappearing of our landscape gradually. This fact, together with the lack of specific studies on the subject, can provoke that in future we shall not be able to know the traditional constructive types characteristics of each area. The aim of this study is to determine the basic type of little bridges wich are traditional in the area of “Terra cha” (Lugo, Spain). For that, some of these engineering structures have been analysed, planned and photographed. After the analysis, it has been able to determine that the small bridges characteristics of the area are trabeated, and stony deck of one or several span.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Abstract
The objective of this study is to establish bioclimatic design strategies using the
Spanish agrarian popular architecture as a model. The bioclimatic strategies
have different purposes depending on the dominant regional climatic factor.
Spain is located within the zone of temperate climate, in particular within the
Mediterranean type. Nevertheless and in spite of their small extension, many
types of climatic areas with widely varying characteristics exists in Spain. In
this article the climatic classification proposed by the Building Technical Code
is employed. The agrarian popular architecture has responded to these different
climates applying different design strategies. By observing cases of popular
constructions, suggestions about the passive design strategies suitable for each
climatic zone are made.
Keywords: Spanish agrarian architecture, Mediterranean climate
1. Introduction.
The aim of this study is to suggest bioclimatic design strategies for the different areas of
Spain. This article is based on the climatic classification proposed by the “Building
Technical Code” that is going to take effect at an early date, replacing the current Building
Basic Regulation NBE-CT-79. The climatic classification of the Building Technical Code
divides Spain into twelve zones made by the combination of the summer and winter
conditions.
The suggestion of the suitable bioclimatic design strategies for each zone is carried out
taking into account cases of popular constructions found in bibliography. Agrarian popular
architecture has met the different climatic conditions by the implementation of design
strategies. Many years ago when the modern systems of environmental control did not
exist, man was able to found the means for the protection against inclement weather as well
as for taking advantages of natural energy. In this article the popular construction is
presented as the beginning of bioclimatic architecture. The design strategies employed in
this type of constructions are passive strategies, it is to say that these strategies do not need
the use of additional energy.
2. The climatic zones of Spain based on the Building Technical Code.
Spain is a country located in the south – west part of the European continent. It is situated
in the temperate area, between latitudes 43º47´24´´ N (Estaca de Bares) and 36º00´3´´ (
Punta de Tarifa), and between longitudes 7º00´29´´ E (Cape of Creus) and 5º36´40´´ O
(Cape of Tourinan).
The area of Spain is 580.850 km2
. It borders on Cantabrian Sea, France and Andorra to the
North, on Mediterranean Sea to the East, on Mediterranean Sea and Atlantic Ocean to the
South and on Portugal and Atlantic Ocean to the West.
2. 2
Due to its situation Spain belongs to the temperate climate area, although it is said that
Spain has a Mediterranean climate (this term is applied to the areas surrounding the
Mediterranean Sea).
Nowadays, there is no climatic classification of Spain focused on the bioclimatic
architecture. In this study the climatic classification of the Building Technical Code for the
calculation of the required thermal insulation is used.
The Building Technical Code is a group of regulations that the buildings should observe for
improving the quality. It establishes the minimum requirements related to the acoustic,
thermal and structural conditions of the building materials as well as of the installations
used in buildings. This study centres on the part of the Building Technical Code related to
the requirements for energy savings. Like in the current Building Standard (NBE-CT-79),
the upper limit of the thermal transmission coefficient depends on the climatic conditions
of the place where the building will be constructed. There are differences between the
climatic classification proposed in both Regulations. The NBE-CT-79 establishes 5
climatic zones: A,B,C,D and E1
by using different levels of degree/days during the heating
season. In the other hand, the Building Technical Code establishes 12 climatic zones by
combining the heating and cooling season conditions of the main Spanish cities (see table
1). The climatic zones are set through the climatic severities2
, there is a climatic severity
for winter and another for summer (see figure 1)

Summer climatic severity: zone 1= 0.6; zone 2= 0.6 – 0.9; zone 3= 0.9 – 1.25; zone 4> 1.25
The hottest areas are the ones with lowest winter climatic severity and highest summer
climatic severity, while the coldest areas are the ones with highest winter climatic severity
and lowest summer climatic severity.
The table 1 shows the climatic classification of all the Spanish provincial capitals.
3. Spanish popular architecture.
In order to suggest some passive design strategies for the different climatic areas defined
above, we turned to the main references about Spanish popular construction (Flores, 1974;
Claret Rubira, 1976; Feduchi, 1984; Benito, 1998; Ponga, J.C; Rodríguez, M.A, 2000). The
relationship between different construction typologies and prevailing climatic conditions
was analyzed.
The way of establishing the sustainable construction is easy: to restore the values from
traditional architecture and to make good use of the technologic advances. The features of

Zone A <= 400 annual degree/day; Zone B: from 401 to 800 annual degree/day; Zone C: from 801 to 1300
annual degree/day; Zone D: from 1301 to 1800 annual degree/day, and Zone E > 1800 annual degree/day. The
degree/days are calculated on the base 15-15 Celsius degree according to the Regulation UNE:24.046.

The climatic severity is a meteorological parameter which combines the influence of the air temperature and
the solar radiation, so that in two locations whose climatic severity is the same, the same building will have
the same energy requirements.

different world climates have formed the indigenous architectural shapes for each different
geographical location.

Besides the adaptation to the prevailing climatic conditions, there are other parameters
influencing the vernacular architectural shapes, as: topography, availability of building
materials, customs, familiar organization, and way of living of different people.
In Spain, due to its wide climatic variation, lot of traditional architectural typologies appear.
The basis of this article is the study of specific popular buildings that make use of certain
construction elements for the “protection against” or the “use of” the prevailing climatic
factors. The most important references about vernacular architecture have been revised,
focusing on the cases where the author mentions clearly the relationship between some
concrete constructive element and the climate of the place. From the whole cases found in
the bibliography, only the ones with design strategies directly related to the climatic
parameters employed in the climatic classification of the Building Technical Code
(temperature and solar radiation) were selected. Eighty nine cases of popular construction
with graphical information were analyzed and grouped by climatic zones (see table 2).

The constructive elements found in the analyzed cases try to achieve the next objectives:
• Protection against solar radiation: It is needed when the air temperature is higher
than 21º C (Olgyay, 1998), although this value varies according to the location of
the building and its final use. The constructive elements employed for the protection
against solar radiation try to avoid the overheating and the excessive natural lighting
inside the building. The solar protectors can be fixed or mobile, horizontal or
vertical, and interior or exterior. They are usually placed on the façade openings, but
in areas where solar radiation is extremely high the structural parts of the buildings
are also in the shadow. The constructive elements most usually employed to provide
shadow to the building are: wing walls, portals, window shutters, window blinds,
curtains, lattices, trees and other vegetation. In addition, there is another system
whose task is to reflect the solar radiation, so it should be considered as a strategy of
protection against solar radiation, it is the use of light colors for painting the façade.
• Use of solar radiation: Three stages are required: capture, store and distribution of
solar energy. The elements designed for the passive use of solar energy can carry
out the three stages or only some of them, in this case another part of the building
will develop the rest.
• High thermal inertia: This strategy is used in areas where the oscillation of
temperature is high during the day and during the year, as much in cold climates as
5. 5
in hot ones. The thermal inertia causes a gap and a softening of the exterior
temperature wave. An example of the use of high thermal inertia is the underground
construction.
• Protection against cold: This objective is achieved by means of constructive
elements that insulate the building from the exterior environment, as window
shutters. Although there is other elements that do not protect the building against
cold, they are characteristic of cold climates as the steep pitched roofs for avoiding
the accumulation of snow.
• Shape and location of the building: The compact shapes reduce the contact with the
exterior environment, so they are found in areas of extreme climates. On the
contrary, with extended shapes the exposed surface is higher so the contact with the
exterior environment is higher and the possibility of ventilation is increased. On the
other hand, the selection of the location of settlements has been an important task
since ancient times, the best places are the ones protected from the inclemency of
the weather and rich in natural resources.
4. Results.
The analysis carried out in this article shows that taking the vernacular architecture as the
model of bioclimatic architecture, it is only possible to make suggestions for areas wider
than the ones proposed by the Building Technical Code (CTE).
The results are showed in the next tables:

5. Conclusions.
The proposal of bioclimatic design strategies taking the vernacular architecture as a model
only allows to make a distinction between wide areas where there are important changes in
the constructive typologies. Naturally, the majority of cases of popular buildings in which
there is a clear relationship between some particular constructive element and the climate
7. 7
match with areas where the weather is hard. Popular architecture give answer to social,
cultural and economic situation of the location, as well as to the dominant climate and to
the suitability of building materials. In areas where the climate is harsh (cold or hot), the
climatic parameter is more important than the rest so the relationship between climate and
construction is more clear. In the transitional zones generalizations can not be made,
however the observation of the prevailing constructive typology in the area will help in the
establishment of some design elements for the integration of the construction on the
environment.
