This study introduces a Bayesian network model to evaluate the comfort levels of occupants of two non-residential Norwegian buildings based on data collected from satisfaction surveys and building performance parameters. A Digital Twin approach is proposed to integrate building information modeling (BIM) with real-time sensor data, occupant feedbac...

Numerous buildings fall short of expectations regarding occupant satisfaction, sustainability, or energy efficiency. In this paper, the performance of buildings in terms of occupant comfort is evaluated using a probabilistic model based on Bayesian networks (BNs). The BN model is founded on an in-depth analysis of satisfaction survey responses and...

This study aims to evaluate the utilization of technology known as Digital Twin for fault detection in buildings. The strategy consisted of studying existing applications, difficulties, and possibilities that come with it. The Digital Twin technology is one of the most intriguing newly discovered technologies rapidly evolving; however, some problem...

This study proposes a novel Digital Twin framework of heating, ventilation, and air conditioning (HVACDT) system to reduce energy consumption while increasing thermal comfort. The framework is developed to help the facility managers better understand the building operation to enhance the HVAC system function. The Digital Twin framework is based on...

Detailed parametric analysis and measurements are required to reduce building energy usage while maintaining acceptable thermal conditions. This research suggested a system that combines Building Information Modeling (BIM), machine learning, and the non-dominated sorting genetic algorithm-II (NSGA II) to investigate the impact of building factors o...

The Architecture, Engineering, Construction, and Facility Management (AEC-FM) industry is increasingly affected by digital technologies that monitor sensor network data and control automation systems. Advances in digital technologies like Digital Twin offer a high-level representation of buildings and their assets by integrating the physical and di...

The building industry consumes the most energy globally, making it a priority in energy efficiency initiatives. Heating, ventilation, and air conditioning (HVAC) systems create the heart of buildings. Stable air handling unit (AHU) functioning is vital to ensuring high efficiency and extending the life of HVAC systems. This research proposes a Digi...

Building information modelling (BIM) software is increasingly being used in as a visual road design tool and offers real-time information on material demands as designs change. Life cycle assessment (LCA) is a tool that is used to measure the lifetime environmental impacts of systems, materials and processes. LCA data sets are organized according t...

This paper describes how co-operation on Research, Development, and Innovation (RD&I) between the university and the value chain within road construction has resulted in increased awareness on the responsibility public institutions have to support industry, and at the same time attend fairness and equal treatment between industrial competitors. Uni...

The Bachelor of Science education in engineering is limited by the Norwegian Ministry of Education and Research (UHR) to 180 points in the European Credit Transfer System (ECTS). A normal study progress is three years consisting of two semesters, totally 6 semesters comprising courses summarising up to 30 ECTS. In 2011 a new framework for engineeri...

This paper describes how cooperation on research, development and innovation (RD&I) between building-clients, industry, and the university was initiated and facilitated to develop (localised) capabilities. The initiator was the regional university; aiming both at supporting the societal development and benefiting engineering education. A year after...

Ultra High performance Concrete (UHPC) has been around for three decades and Elkem has been involved since the early days; first with Densit® and later with Elkem’s proprietary brand, Ceramite®, based on CA cement. In order to benefit from the concept on a larger scale, local raw materials should be used. The project described investigated this opt...
