Toward building energy management: Electric analog modeling for Thermal behavior simulation
2016Co-Authors: Hoang Anh Dang, Benoit Delinchant, Frédéric WurtzAbstract:The most energy in buildings is used for space cooling and heating. Thus, the Thermal analysis is necessary to reach Thermal comfort and energy efficiency in buildings. In this paper, we present a Thermal Envelope modeling based on Thermal-electrical analogy for Thermal behavior simulation. The research object is a real platform inside our laboratory building in France. To illustrate this study, two Thermal zone model represent two room of this platform, and they are surrounded by another Thermal zones of laboratory building. Their parameters have been identified from Envelope properties. Then, these models are implemented in a simple equivalent electric circuit, simulated and validated with measurement data.

OPTIMAL SIZING OF A COMPLEX ENERGY SYSTEM INTEGRATING MANAGEMENT STRATEGIES FOR A GRID-CONNECTED BUILDING
2015Co-Authors: Van Binh Dinh, Benoit Delinchant, Frédéric WurtzAbstract:This paper presents the simultaneous design and energy management of a complex energy system (heating, air conditioning, PV using battery bank) for a grid-connected building. The Thermal comfort, determined by a low order dynamic Thermal Envelope model, and the life cycle cost (LCC) will be taken into account as optimization criterions meanwhile the load demand covering requirements will be considered as a constraint. This results in the formulation of a complex optimization problem with a lot of parameters and constraints, but we will show that it can be quickly computed using a gradient based optimization approach. A study case is a building that is being constructed in South-East of France.

A new co-simulation architecture for mixing dynamic building simulation and agent oriented approach for users behaviour modelling
2013Co-Authors: Sana Gaaloul, Benoit Delinchant, Hoang Anh Dang, Ayesha Kashif, Frédéric WurtzAbstract:This paper deals with an interoperability solution based on co-simulation that ensures tools collaborative working for building's global simulation. The proposed solution couples two specialized tools from different domains and characterized by different modelling approaches in order to simulate a low energy building. A dynamic Thermal Envelope model in SIMULINK is coupled to a multi-agent based occupants' behaviour model realized in BRAHMS. The co-simulation of these two tools has been established to take advantages of their specific capabilities for a detailed simulation using physical and inhabitants' behaviour (cognitive abilities) models. This work is realized to simulate an efficient building control, taking into account the system's complexity. A co-simulation architecture based on software component standard is also proposed. The use of this technique helps to unify programming interfaces of several BPS1 tools in order to facilitate and generalize co-simulation use cases.

IECON - Software component architecture for co-simulation applied to the coupling between a building's Thermal Envelope and its inhabitant behaviour
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Co-Authors: Sana Gaaloul, Benoit Delinchant, Frédéric Wurtz, Stéphane PloixAbstract:This paper proposes a co-simulation architecture based on software component standard. It proposes a pattern to unify the co-simulation interfaces of several building energy simulation tools. It will thus facilitate and generalize the establishment of a co-simulation. Advantages of this strategy are highlighted through the coupling between the software COMFIE for Thermal Envelope simulation and the tool BRAHMS for occupant behaviour simulator, in the Matlab/Simulink environment. Linking these two tools is essential to take profit from their specific skills in each area and ensure a detailed simulation of both precise physical models and computational models of human cognitive abilities. This is needed to ensure an efficient building control taking into account the complexity of this system

SOFTWARE COMPONENTS FOR DYNAMIC BUILDING SIMULATION
2011Co-Authors: Sana Gaaloul, Benoit Delinchant, Frédéric Wurtz, Franck VerdièreAbstract:This paper describes a standard of software components for building energy and control systems modeling. This technology is well positioned to overcome the limits of existing tools and to allow better collaboration between various engineering domains coexisting in building field. A standard named ICAr is proposed in addition to the Modelica approach to ensure models interoperability. So, the strengths and lacks of the "white box" modeling based on Modelica language will be firstly discussed in order to prove the necessity to introduce the "black box" modeling based on software components and to highlight the complementarity of these two approaches via "plug'out" and "plug' in" notions . As the white modeling was standardized by defining universal languages, this work proposes a norm of software component named ICAr. So, this paper defines the specifications of the ICAr standard: inputs, outputs and interfaces for external communication. Moreover, to demonstrate the importance of this approach in building performance simulation, a Thermal Envelope will be coupled to a simple heater model in different simulation environments using a mixed approach.

Thermal tolerance of early development in tropical and temperate sea urchins: inferences for the tropicalization of eastern Australia
Marine Biology, 2014Co-Authors: Natasha A. Hardy, Miles Lamare, Sven Uthicke, Kennedy Wolfe, Symon Dworjanyn, Maria ByrneAbstract:The Thermal Envelope of development to the larval stage of two echinoids from eastern Australia was characterized to determine whether they fill their potential latitudinal ranges as indicated by tolerance limits. The tropical sand dollar, Arachnoides placenta , a species that is not known to have shifted its range, was investigated in Townsville, northern Australia (19°20′S, 146°77′E), during its autumn spawning season (May 2012). The subtropical/temperate sea urchin, Centrostephanus rodgersii , a species that has undergone poleward range expansion, was investigated in Sydney, southern Australia (33°58′S, 151°14′E), during its winter spawning season (August 2012). The Thermal tolerance of development was determined in embryos and larvae reared at twelve temperatures. For A. placenta , the ambient water temperature near Townsville and experimental control were 24 °C and treatments ranged from 14 to 37 °C. For C. rodgersii , ambient Sydney water temperature and experimental control were 17 °C, and the treatment range was 9–31 °C. A. placenta had a broader developmental Thermal Envelope (14 °C range 17–31 °C) than C. rodgersii (9 °C range 13–22 °C). Both species developed successfully at temperatures well below ambient, suggesting that cooler water is not a barrier to poleward migration for either species. Both species presently live near the upper Thermal limits for larval development, and future ocean warming could lead to contractions of their northern range limits. This study provides insights into the factors influencing the realized and potential distribution of planktonic life stages and changes to adult distribution in response to global change.

Choosing the best nature’s strategy with the highest thermodynamic potential for application in building Thermal Envelope using MCA analysis
Energy Procedia, 2018Co-Authors: Ruta Vanaga, Andra Blumberga, Julija Gusca, Dagnija BlumbergaAbstract:Abstract There is rapid growth in energy efficiency in the building sector oriented to zero energy or plus energy building concepts. Additionally building designs need to solve a complex task combining energy and environmental requirements, as well as social and economic performance requirements in one architectural object. Therefore when constructing new generation buildings, there is a necessity to seek for new strategies for inspiration. In this respect nature plays a core role for such inspiration. However, the process whereby one can integrate nature-inspired processes in building applications faces problems via the technical evaluation of such strategies. This research proposes a multi-criteria analysis methodology combining Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods in order to select the best nature-inspired strategies for climate adaptive building shells. Based on the methodology, four nature strategies are analysed regarding seven thermodynamic criteria: heat loss in the Thermal Envelope, heat loss in air exchange, Thermal inertia and solar heat gains, energy storage, energy production and changing surface characteristics. The proposed selection methodology allows architects and engineers to screen the most appropriate nature inspired strategy to be applied for energy efficiency in buildings taking into account a set of technical criteria.

First Steps to Develop Biomimicry Ideas
Energy Procedia, 2015Co-Authors: Ruta Vanaga, Andra BlumbergaAbstract:Abstract There is urgent need for new building insulation materials or building Thermal Envelope concepts while it is often economically not feasible to achieve nearly zero energy level for buildings in northern climate. The purpose of this study is to research and create solution for applicable facade system or wall construction itself that has dynamic optical and dynamic properties that will adapt to external weather conditions and will be able to react to different outdoor and indoor temperature and lighting conditions using biomimetic principles avoiding the necessity for additional energy input. The goal of such solution is to gather the energy of Sun in summer for heating in winter.
