building energy Simulation in real time through an open standard Interface
Energy and Buildings, 2016Co-Authors: Xiufeng Pang, Daniel Fuller, Anna Liao, Thierry S Nouidui, Michael Wetter, Philip HavesAbstract:Building energy models (BEMs) are typically used for design and code compliance for new buildings and in the renovation of existing buildings to predict energy use. The increasing adoption of BEM as standard practice in the building industry presents an opportunity to extend the use of BEMs into construction, commissioning and operation. In 2009, the authors developed a real-time Simulation framework to execute an EnergyPlus model in real time to improve building operation. This paper reports an enhancement of that real-time energy Simulation framework. The previous version only works with software tools that implement the custom co-Simulation Interface of the Building Controls Virtual Test Bed (BCVTB), such as EnergyPlus, Dymola and TRNSYS. The new version uses an open standard Interface, the Functional Mockup Interface (FMI), to provide a generic Interface to any application that supports the FMI protocol. In addition, the new version utilizes the Simple Measurement and Actuation Profile (sMAP) tool as the data acquisition system to acquire, store and present data. This paper introduces the updated architecture of the real-time Simulation framework using FMI and presents proof-of-concept demonstration results which validate the new framework.

using the Interface peclet number to select the maximum Simulation Interface width in phase field solidification modelling
Computational Materials Science, 2013Co-Authors: Hongbiao Dong, Jon DantzigAbstract:This study investigates the use of Interface Peclet number P = w/(Dl/Vtip), to determine the Interface width (w) used in phase-field Simulations, where Dl is the liquid diffusivity and Vtip is the tip velocity. The maximum Simulation Interface width (wmax) under varied growth conditions was analysed via convergence analysis and it was found that there is a limit of P for the maximum Interface width at various velocities. Converged results can be obtained only when w < wmax = 0.075Dl/Vmax where Vmax is the maximum growth velocity during transient solidification. The effect of the inclusion of finite solid diffusivity on the P limit in selecting wmax was analysed, and little influence was observed.

“Graphical” Jogthrough: expert based methodology for user Interface evaluation, applied in the case of an educational Simulation Interface
Computers and Education, 1999Co-Authors: Stavros Demetriadis, Athanasios Karoulis, Andreas PombortsisAbstract:“Walkthrough” and “Jogthrough” techniques are well known expert based methodologies for the evaluation of user Interface design. In this paper we describe the use of “Graphical” Jogthrough method for evaluating the Interface design of the Network Simulator, an educational Simulation program that enables users to virtually build a computer network, install hardware and software components, make the necessary settings and test the functionality of the network. Graphical Jogthrough is a further modification of a typical Jogthrough method, where evaluators' ratings produce evidence in the form of a graph, presenting estimated proportion of users who effectively use the Interface versus the time they had to work with it in order to succeed effectiveness. We comment on the question: “What are the possible benefits and limitations of the Graphical Jogthrough method when applied in the case of educational software Interface design?” We present the results of the evaluation session, and concluding from our experience we argue that the method could offer designers quantitative and qualitative data for formulating a useful (though rough in some aspects) estimation about the novice–becoming–expert pace that end users might follow when working with the evaluated Interface.
