This study presents a comprehensive review of various advanced methodologies that have been used to enhance the structural and thermal performance of masonry walls through innovative and sustainable retrofitting/upgrading techniques. Focusing on three primary approaches—mechanical/structural retrofitting, thermal retrofitting, and integrated (struc...

There is a pressing need to develop carbon fiber composites with sustainable fillers that enhance their strength without increasing costs or environmental impact. Such advancements would not only improve performance in high-stress applications but also align with global sustainability goals by utilizing eco-friendly materials and reducing waste. Th...

Existing masonry buildings require appropriate structural and thermal upgrading to meet structural safety and energy efficiency according to the current standards. Textile Reinforced Mortar (TRM) presents several advantages for masonry strengthening, but the production of man-made fibers is often expensive and environmentally harmful. For this reas...

Climate change not only affects the environment directly but also challenges the existence of human civilization. Changes observed in the marine environment indicate the planet’s health. Continuous ocean observations (ambient conditions, water quality, aquatic life, and disaster management) are crucial for checking and balancing climate change. Thi...

The construction and building industry is responsible for a significant amount of carbon emissions due to its high energy consumption throughout the lifecycle of buildings. Many masonry buildings were constructed without following any seismic or energy standards, making them vulnerable to both natural and man-made disasters. This paper discusses th...

Usually, man-made fibers are used in the construction and building sector for retrofitting or reinforcing purposes. However, these fibers are costly, non-biodegradable, non-recyclable, and contribute significantly to a higher carbon footprint, unlike natural fibers. Instead, jute fiber, being a bio-based natural alternative, ranks as the second mos...

The use and application of natural fiber in the Construction and Building sector is gaining momentum due to its various advantages over synthetic fibers, mainly in terms of sustainability, recyclability, and biodegradability. In this paper, two aspects of the jute fiber composite mortar have been discussed. Firstly, the effect of water on the mecha...

Sustainable building materials for integrated (structural and thermal) retrofitting are the need of the hour to retrofit/upgrade the seismic vulnerable and ill-insulated existing building stocks. At the same time, the use of natural fibers and their recyclability could help construct safer and more sustainable buildings. This paper presents three a...

Energy and water poverty are two main challenges of the modern world. Most developing and underdeveloped countries need more efficient electricity-producing sources to overcome the problem of potable water evaporation. At the same time, the traditional way to produce energy/electricity is also responsible for polluting the environment and damaging...

Both existing and new buildings affect, either directly or indirectly, our environment and eco-systems, mainly due to their contribution to the climate change. Particularly they are responsible for greenhouse gas emission, during the whole life cycle of the building. The use of sustainable materials in the con-struction sector could help in slowing...

The need for a “systemic” approach to reduce both carbon footprint and seismic vulnerability of the built environment is clearly evident nowadays. Therefore, the use of bio-based composites, is gaining consensus as a sustainable solution due to their low environmental impact and promising properties as a construction material. This paper investigat...

For ages, natural fibers have been used as building materials. In the last centuries the man-made fibers, steel and concrete have predominantly dominated construction sector. Climate change has highlighted the importance of sustainable construction that can reduce the carbon footprint and the application of green, natural, recyclable and sustainabl...

The construction sector requires a major part of the produced energy (around 36% globally) and emits the highest amount of greenhouse gases (around 39% globally). Therefore, it has an important impact on global warming and climate change. For centuries the irrational use of natural resources of non-renewable raw materials in the construction and bu...

Our research aims to achieve dual-positive effects in the presented study by raising photovoltaic (PV) panels over the water surface. With this, target experiments were primarily conducted to evaluate the efficiency increments of the PV panel while reducing its operating temperature through passive convective cooling obtained by raising it over wat...

The building sector is known to have a significant environmental impact, considering that it is the largest contributor to global greenhouse gas emissions of around 36% and is also responsible for about 40% of global energy consumption. Of this, about 50% takes place during the building operational phase, while around 10–20% is consumed in material...

Old masonry buildings represent the largest part of traditional constructions. Generally, they are both seismically vulnerable and thermally dispersive. Therefore, the need for seismic and thermal retrofitting aimed at reducing their vulnerability and environmental impact has motivated research efforts towards sustainable retrofitting solutions. Th...

This paper presents with an effective and fast approach to the optimization of the pretension forces in arched bridges with suspended deck, which makes use of the influence matrix method (IMM). The given cable-tensioning procedure leads to a linear system of equations with a reduced number of unknowns and can be effectively implemented within activ...
