The climate crisis due to global warming is intensifying, and international cooperation to curb temperature rise is underway. South Korea has set GHG reduction targets, along with systems for implementation and assessment to achieve these goals. South Korea currently applies the IPCC-Tier2 method based on fuel consumption to estimate GHG emissions at the national level. Additionally, starting in 2024, it has begun estimating GHG emissions at the level of 17 local cities. However, applying the fuel consumption-base...

We are living in an information dense world, where the sustainability is key. Even though civil engineering projects are highly technical, they require precise planning and clear communication channels to be successful and achieve this purpose. For this, in recent years, all around the world, various entities and decision boards worked to put together a set of rules to define and standardize the interaction between all the involved stakeholders (e.g. investors, designers, builders, and operators). Using the BIM (B...

An ecological approach to construction and the Green Building concept force construction processes participants to meet specific requirements. In relation to designers and making designs of buildings, the requirements to be taken into account have also been defined. Above all, social, financial, and environmental benefits throughout the entire lifecycle of a building must be taken into consideration. It is significant to choose materials that ensure the safety and durability of the structure, as well as its therma...

In 2015, the United Nations set 17 sustainable development goals to be achieved by 2030. Among them, the 11th goal is - sustainable cities and communities. Taking into account such factors as increasing urbanization, challenges of well-being in the urban environment, the imbalance of resources, the issue of sustainability of urban areas is becoming more and more relevant. It requires solutions that balances sustainable development in economic, environmental and social dimensions. Urban agriculture is a practice wi...

Changes in land use and architectural renovation are a normal process in historic urban centres, and as a consequence there are changes in the occupation of properties, such as the loss of vegetation cover and filtering soils that could be integrated into the urban green system, which is now almost entirely concentrated in the public space. In this study, a series of orthophotographs of the historic centre of the city of Loja were analysed to determine the changes in vegetation cover and its distribution among squ...

This paper explores the application of augmented reality (AR) in spatial data and 3D model visualization, particularly in the context of smart cities and campuses. The term "smart city" refers to the concept of urban planning that optimizes city space by applying digital technologies to improve the quality of life. Smart cities include innovative solutions in traffic, urban planning, energy, communications and digital management of the city and buildings to provide efficient and sustainable development. We develop...

Global biodiversity decline is dramatic. Urbanization is a global trend that is often driving biodiversity loss. At the same time urban green spaces can maintain high levels of biodiversity. However, for urban Nature-based Solutions to maintain biodiversity they have to be designed and managed with this goal in mind. Furthermore, there are certain risks to biodiversity associated with the urban green infrastructure. These risks merit consideration when urban planning is undertaken. Approaches to green infrastructu...

Even today, factories and production systems are primarily planned using established methods from lean production, developed in the 1990s, which only partially address sustainability. Industrial production significantly impacts climate change; in Germany, for instance, 70% (9.1 million TJ) of the primary energy requirement of 13 million TJ comes from industry, and around 28% of annual new land use is attributed to industrial expansion and new construction. This situation is no longer viable, given the European Com...

The high risk of natural disasters to which Ilha de Mocambique (IM) and its Buffer Zone (BZ) are naturally exposed and the demographic explosion it has suffered increased the loss of ecological wealth, biodiversity and the mischaracterization of the cultural identity it holds. Thus, there are required urgent measures for its values safeguard, preservation and valorization. The primary objective of this proposal is to improve the sustainability of IM and BZ enhancing its development trough landscape and urban plann...

Urban areas are characterized by very intense and complex interactions between built objects and natural elements, especially in terms of the impact they have on the local microclimate. One of the most important aspects of this interaction is the way in which vegetation influences incident solar radiation, which has a major impact on energy consumption, comfort and the overall sustainability of urban areas. In this study, we focus on the city of Zagreb, where we conduct a detailed analysis of the impact of urban v...

This study investigates the relationship between users- comfort and energy consumption in an educational building located in a humid continental climate. Through a year-long monitoring program, we collected data on indoor temperature, humidity, lighting levels, CO2 concentrations, and natural gas consumption. Our analysis revealed that during the heating season, the average indoor temperature was 24.03 degrees Celsius while natural gas consumption reached 41.71 megawatt-hours (MWh). By analyzing the relationship b...

The present research evaluated a facade alternative to reduce the indoor temperature of buildings in the Ecuadorian Amazon (Yantzaza, Ecuador). Three scale models were compared: one with a gabion facade and leafy vegetables (onion, lettuce, basil, chamomile, and cabbage), one with a gabion facade only, and one with a clay brick (traditional) facade. Thermal data from inside the models were analyzed in March (warmest month) and January (coldest month). The results showed that between 13:00 and 15:00 in January and ...

Urbanization is an ongoing trend. It causes various negative issues, including strain on human health and biodiversity. Cities are often subject to negative effects of climate change. Currently green and blue infrastructure are often seen as potential solutions for these problems. However, integration of topographically diverse sites and geological elements into urban landscapes is rarely considered as an important measure for addressing societal and environmental issues in cities. This can lead to lost opportunit...

Construction using 3D printer technology seems to be not just a passing trend and a growing number construction companies are approaching this new construction methodology. Although construction processes with printers are becoming standardized, it is also true that many other aspects must be considered in the design phase. Better this construction methodology becomes known, more architects and engineers will have to learn how to design these constructions, in the methods of statics, systems, etc. A very important...

For the purpose of achieving a sustainable city, there has been a significant increase in the construction of green buildings in recent years. Since these are properties with characteristics that differ from those of ordinary buildings and, therefore, few transactions of comparable properties can be collected in the market area in which they are located, it is very difficult to apply the Revealed Preference Methods for green buildings appraisal. These cases produce the same conditions common to industrial products...

Cities in the Czech Republic and nearby Central Europe usually have a very long tradition. This post shows changes in the long run in the scope and function of green and water areas in selected municipalities. Most of the cities in the region were founded in the Middle Ages, from the 10th to the 13th century. At this time, the issue of water and green cities was directed purely at the utility function of drinking water and food supply. The exception at this time was only the gardens of noble and tin buildings. Ove...
