Towards occupant-centric simulation-aided building design: a case study

ABSTRACT

This paper aims at illustrating the importance of occupant modelling for decision-making during the building design process. It identifies the energy implications of conventional ways of modelling occupants for the design of office buildings. Furthermore, it presents a step towards bridging the gap between the research efforts and conventional practices within the field of building performance simulation (BPS) aided design. The paper first describes occupant-related assumptions that were made during the design process of a case study office building, obtained via stakeholder interviews. Then, the impact of these assumptions on the design decisions is examined through a simulation-based investigation. The stakeholder interviews revealed that professionals from each design discipline made significantly different assumptions about occupants. The simulation results showed that assumptions about occupants and their behaviour impacted predicted energy savings of some design decisions by a factor of five or more.     

The story of N: a social history of the nitrogen cycle and the challenge of sustainability

The assimilation and subsequent elimination of cobalt‐60 by different marine organisms are affected by the mode of contamination: chronic or acute. Experimental cobalt‐60 Contamination of such organisms varies qualitatively and quantitatively according to whether the pollutant is transferred through the water or through the food. The concentration factor with respect to water, the transfer factor through food and the overall contamination estimate show a decrease for the highest trophic levels.     

Project Organizations as Social Networks

High-performance teams achieve outcomes that exceed the expectations of the project and often demonstrate unique or innovative approaches within a final solution. The foundation of this high performance is the ability to focus on the success of the team over individual objectives. However, the recognition of this emphasis is based on the establishment of professional trust and strong communications between the team members. The social network model of construction introduced a dual-focused approach to enhancing these elements and creating high-performance project teams. The approach emphasizes balancing both a traditional project management emphasis on efficiency of communications with a focus on the social factors that move the project team from efficient to effective. In this paper, the model is extended to present the results of four studies of organizations that are full-service engineering companies that also provide construction oversight services. The paper presents the results of these studies in terms of the social network model and the achievement of high performance in the project teams. Analytical and graphical results are presented based on social network analysis techniques to provide a multiperspective analysis of the project teams.
