Debido a un diseño poco reflexivo de los edificios en cuanto a los costes mantenimiento, hoy en día hay edificios extremadamente costosos en este aspecto, tanto económica como ambientalmente hablando. Con el fin de reducir estos excesos, es necesario desarrollar una base de costes con la que se puedan estimar los recursos requeridos para...

Spatial visualization skills are considered essential for a variety of professional careers, especially those related with architecture, engineering, and construction (AEC). A number of studies have proven that these skills are progressively acquired by AEC students during their years in college, being necessary specific pedagogical approaches...

Public policy in Chile proposes reaching carbon neutrality by 2050. Regarding the construction sector, the application of energy efficiency standards in public buildings has been encouraged. However, the contribution of these standards to life-cycle greenhouse gas (GHG) reduction still remains unknown. This study aims to determine the impact of...

According to numerous studies, approximately 90% of energy consumption in the life cycle of buildings occurs during the use and maintenance phase. The main aim of this study is to propose a method for the detailed calculation of costs and environmental impact corresponding to this phase,thus providing useful data for Facility Managers. The...

Evaluation of the environmental impact caused by construction materials frequently presents such obstacles as the mismatch between the construction project location and where the LCA database was made, lack of transparency, and/or the unsuitability of the data to the building project conditions, thereby making it necessary to establish a...

Due to poor design of buildings in terms of maintenance, there are a number of buildings today thatremain extremely expensive to maintain, both economically and environmentally. In order to mitigatethese overheads, the development of a cost database is needed with which the resources required to cleanand maintain buildings can be estimated....

The construction industry is currently technologically challenged to incorporate new developments for enhancing the process, such as the use of 3D printing for complex building structures,which is the aim of this brief. To do so, we show a systematic study regarding the usability and performance of mobile manipulators as ...

Se ha definido un indicador teórico del coste económico y ambiental que debe tener un edificio público en función de su uso y superficie. Se ha seguido la metodología para el cálculo de Huella Ecológica, la norma UNE-EN 15221 y el Plan General de Contabilidad de la Administración de la Junta de Andalucía y de sus Agencias Administrativas y de...

More effective construction technologies are needed nowadays in order to reduce construction energy consumption during the life-cycle of buildings. Besides which, it is necessary to consider the economic feasibility and associated costs within the framework of these alternative technologies so as to favouring their practical implementation in...

Las construcciones mediante impresion-3D pueden reducir recursos y tiempos de ejecución, impulsando la productividad y la sustentabilidad de la edificación. Si bien esta nueva tecnología se está desarrollando en distintas partes del mundo y ya hay ejemplos diversos, no se han determinado las condiciones de diseño arquitectónico con este nuevo...

The knowledge of the workspace for a robotic system on construction sites represents an essential resource to ensure the work progress, guarantee the safety of the construction tasks, and avoid robot damage. Despite the dramatic development of 3D printing technologies with robotic systems in recent years, these are still several challenges to...

La construcción impresa en 3D ha surgido recientemente como una nueva tecnología constructiva, a través de experiencias diseminadas alrededor del mundo. Este artículo revisa la documentación existente y los ejemplos de esta tecnología para caracterizar sus proyecciones potenciales, en particular, aquellas orientadas a mejorar la productividad y...

Existing tools for environmental certification of buildings are failing in their ability to reach the general public and to create social awareness, since they require not only specialized knowledge regarding construction and energy sources, but also environmental knowledge. In this paper, an open-source online tool for the estimation of the...

Integrated life-cycle assessment (LCA) tools have emerged as decision-making support for BIM practitioners during the design stage of sustainable projects. However, differences between methodologies applied for determining the environmental impact of buildings produce significant variations in the results obtained, making them difficult to be...

The construction sector is one of the most polluting industries, generating between 30% and 40% of the worldwide environmental burden in terms of raw materials, direct and indirect energy consumption, waste, and CO2 emissions. Recent advances in computer science and data management have facilitated the evaluation of present and future impacts,...

Building Simulation Software tools support designers to analyse and identify certain users´ behavioural patterns; besides, they can predict future trends about the energy demand and consumption in buildings, as well as CO2 emissions, design analysis, energy efficiency, or lighting. These tools allow to collect and report information about such...

In Spain, most businesses are medium to small size enterprises, representing 90% of the total, but there is a lack of studies of the types of building this sector uses. The main objective of this paper is to present a method for the evaluation of small industrial construction projects to facilitate the introduction of eco-efficient solutions....

Collaborative work in Building Information Modeling (BIM) projects is frequentlyunderstood as the interaction of modelers in an asynchronous way through modification requests orvia e-mail/telephone. However, alternative work methodologies based on creating a common andsynchronous environment allow solving issues instantaneously during...

Since the end of the twentieth century, discussion on dwelling rehabilitation versus its demolition and new construction has been steadily increasing in intensity, which is especially due to the necessity for the regeneration of urban centres. However, rehabilitation is not always considered the most economical solution, and demolition and new...

3D-printed construction allows elaborating building elements with diverse shapes that are digitally controlled. This paper exposes the modeling of 3D-printed curved walls through parametric programming in building information modeling (BIM) in order to support a cost-efficient building design. The advantage of using curved walls is based on the...

In the last few years, scattered experiences of the application of additive manufacturing in the construction of buildings using 3D printing with robots or automated equipment have emerged around the world. These use a variety of procedures and suggest relevant advantages for the construction industry. In order to identify the different...
