“…Without reliable integration of such siloed information, the construction industry still remains trapped in the inefficiency loop of unsustainable construction processes characterized by resource waste and poor energy efficiency [4]. With a CDE, all information silos generated by different departments can be linked together, visualized and used as an engine to power sustainable design processes [20]. The construction industry is responsible for consumption of energy in two principle ways i.e.…”

“…Though designers have very little influence on the operational energy use of a building, adopting LBD driven approaches, creates a comprehensive basis for improved decision making during the iterative processes of optimizing building designs [18]. Current research in the AEC industry is slowly emerging towards utilizing ontological knowledge representation techniques to semantically link heterogenous building information using semantic web tools [20]. With the emergence of linked building data comes a problem of handling and utilizing BIG data coherently.…”

“…With the extraordinary wealth of building data available on construction projects, it is safe to assume that many stakeholders integrate and use this data to inform important design decisions that minimize resource use during building construction and eventual operation. A survey proves otherwise that less than 50% of construction organizations highly value integrated building data in critical decision making [20]. Achieving sustainable designs entails complex and iterative processes that often overlap and can benefit greatly from LBD driven approaches [19].…”

“…For example, to minimize air conditioning costs without compromising indoor air quality requires designers to make decisions basing on past facility management data, occupant behavior data, HVAC system architecture information, building material properties, indoor envelope configurations, building sensors etc. [20]. All this data is readily available on construction projects but more often than not existing in isolated data silos where it cannot be used heuristically to efficiently optimize building designs.…”

Over the years, the construction industry has been evolving to embrace the delicate balance between buildings and a sustainable environment by optimizing resource use to create greener and more energy efficient constructions. Sustainable building design and optimization is a highly iterative and complicated process. This is mainly attributed to the complex interaction between the different heterogenous but heuristic construction processes, building systems and workflows involved in achieving this goal. Augmented Reality (AR) has rapidly emerged as a revolutionary technology that could play a key role towards improving coordination of sustainable design processes. AR makes possible the real-time visualization of a threedimensional (3D) building prototype with linked design information in a real-world environment based on a twodimensional drawing. From past research, it is evident that this technology relies heavily on a common data environment (CDE) that syncs all construction processes with their related building information in one central model. However, due to the fragmented nature of the construction industry, different domain experts generate and exchange vast amounts of heterogenous information using different software tools outside a CDE. This paper therefore investigates the performance gap that exists within Malaysia’s construction industry towards using linked building data (LBD) with AR to improve the lifecycle sustainability of buildings. The results of this study clearly delineate how current construction practices in Malaysia do not favor the use of AR however, stakeholder perception is positive towards adoption of workflows that link heterogenous building data to streamline AR with sustainable building design and construction.

Este artigo apresenta os resultados obtidos na primeira fase de desenvolvimento de uma aplicação que integra a interface de um ambiente de projeto BIM (Building Information Modeling) ao simulador acústico BRASS (Brazilian Room Acoustic Simulator). O objetivo do projeto é obter um ambiente de auralização integrado à ferramenta de concepção do projeto, buscando facilitar o trabalho de simulação acústica. Uma interface de auralização unificada evita que arquitetos e engenheiros tenham que comutar entre diversas aplicações gráficas para ouvir o resultado da simulação, facilitando a tomada de decisão projetual. Para efetuar a auralização de salas, os procedimentos de cálculo utilizados pelo simulador acústico BRASS foram implementados no aplicativo de modelagem BIM Revit, testando duas implementações: scripts programados no ambiente de programação visual Dynamo e funções programadas em C# no ambiente .NET. Como resultado da integração, são obtidos arquivos de áudio biauriculares que consideram a espacialidade do som através das funções de transferência relativas à cabeça e a visualização da posição da fonte sonora e do campo acústico, definido pelo conjunto de raios sonoros que se propagam dentro do ambiente simulado. São apontados problemas referentes ao desempenho necessário para realizar este tipo de simulações e relacionados à classificação dos parâmetros utilizados.

AEC Digital Twin Data - Why Structure Matters

With the increasing adoption of the Digital Twin concept in the construction industry in the operations and maintenance phase, researchers and practitioners are increasingly seeking suitable technological solutions for the design and construction phases. While it is widely accepted that the required platforms hosting the digital twin must be cloud-based to fulfill the requirements of ubiquitous accessibility and centralized consistency, questions regarding the need for data schema remain. Some academics argue that a structure-free organization of data is suitable for realizing digital twins and the data streams from and to the respective platform. Hands-on experience in the BIM2TWIN project supports a counter argument, i.e., that structure-free data is insufficient for most use cases around AEC Digital Twins. The sheer information complexity of construction projects requires well-defined data structures enabling unambiguous and errorless interpretation. This becomes apparent when reflecting on the well-established concept of the data-information-knowledge pyramid describing that raw data must be processed into understandable and meaningful high-level information for human decision makers, subsequently providing the basis for crossproject domain knowledge. Based on this observation, we highlight that objectoriented modeling is a widely recognized information modeling technique that facilitates the structuring of complex domain information. We compare it with ontology-based model concepts that provide a similar, yet more abstract means for information modeling.
