Sequential Monte Carlo For On-Line Estimation Of The Heat Loss Coefficient, Simon Rouchier, Maria José Jiménez, Sergio CastañO
Sequential Monte Carlo For On-Line Estimation Of The Heat Loss Coefficient, Simon Rouchier, Maria José Jiménez, Sergio CastañO
International Building Physics Conference 2018
The calibration of building energy models based on in-situ sensor information is generally performed after the measurement period, using all data in a single batch. Alternatively, on-line parameter estimation proposes updating a model every time a new data point is available: this allows observing a direct relation between external events and the identifiability of parameters. The present study uses the Sequential Monte Carlo method to train a RC model, and thus estimate a Heat Loss Coefficient, and other parameters, sequentially. Results show the direct impact of solicitations (solar irradiance and indoor heat input) on this estimation, in real time. The …
Lightlearn: Occupant Centered Lighting Controller Using Reinforcement Learning To Adapt Systems To Humans, June Young Park, Thomas Dougherty, Hagen Fritz, Zoltan Nagy
Lightlearn: Occupant Centered Lighting Controller Using Reinforcement Learning To Adapt Systems To Humans, June Young Park, Thomas Dougherty, Hagen Fritz, Zoltan Nagy
International Building Physics Conference 2018
Humans spend up to 90% of their time indoors, thus building systems should maintain the indoor environment within the comfort range. In this paper, we present LightLearn, a reinforcement learning based occupant centered lighting controller. The control agent interacts with the occupant non-intrusively, learns her/his preferences, and determines actions for achieving both human comfort and energy saving. We present system hardware, control algorithm, and experimental results of LightLearn for an office space. Compared to the full (9am-5pm) and occupancy based control, LightLearn reduced 83% and 63% of operation time, respectively, by adapting to the occupant.

International Building Physics Conference 2018
The integration of a wireless-transponder system into building components (“intelligent building materials”) with built-in relative humidity and temperature sensors (RH, T) allows for a cost-efficient and non-destructive measurement of data regarding the current hygrothermal conditions of a building. Even during long-term use, quality assurance of the building system can be achieved by “looking into” the component. This supports the sustainability of the building from both a technical and an ecological point of view. In this paper, the development, the functionality and the exemplary application of Radio Frequency (RF), as well as an hygro-thermal analysis for solving the challenges of building-climatology …
A Resilient Refurbishment Project For An Italian Large Sports Hall, Renata Morbiducci, Andrea Morini, Alberto Messico, Clara Vite
A Resilient Refurbishment Project For An Italian Large Sports Hall, Renata Morbiducci, Andrea Morini, Alberto Messico, Clara Vite
International Building Physics Conference 2018
In Europe the management costs and lack of flexibility of the sports halls, built in the second half of the ‘900, brought to the progressive abandonment of many structures. In this context the environmental, social and economic sustainable aspects of a refurbishment project of an Italian large sports hall, named “Palasport”, are presented. It was designed by a group of architects and engineers and completed in 1962. It is located in the expo area of Genoa, a north Italian city, called “Fiera del Mare” and it plays a strategic role in the social community. In the past it hosted several …

Investigation Of Energy Modelling Methods Of Multiple Fidelities: A Case Study, Naveen Kumar Muthumanickam, Vaclav Hasik, Mehmet Unal, Simon W. Miller, Tina Unwalla, Melissa M. Bilec, Lisa D. Iulo
International Building Physics Conference 2018
Building energy modelling has become an integral part of building design due to energy consumption concerns in sustainable buildings. As such, energy modelling methods have evolved to the point of including higher-order physics, complex interconnected components and sub-systems. Despite advances in computer capacity, the cost of generating and running complex energy simulations makes it impractical to rely exclusively on such higher fidelity energy modelling for exploring a large set of design alternatives. This challenge of exploring a large set of alternatives efficiently might be overcome by using surrogate models to generalize across the large design space from an evaluation of …
Pareto Optimality Analysis For Evaluating The Tradeoff Between Visual Comfort And Energy Efficiency, Maryam Hamidpour, Vincent Blouin
Pareto Optimality Analysis For Evaluating The Tradeoff Between Visual Comfort And Energy Efficiency, Maryam Hamidpour, Vincent Blouin
International Building Physics Conference 2018
Architectural designs are increasingly driven by both sustainability and health, which requires evaluating the tradeoff between visual comfort and energy consumption. Lack of daylight leads to poor visual comfort and health issues but reduces heat gains, while excessive daylight may lead to over-illumination, glare, and high heat gains. Identifying the tradeoff between multiple criteria is an intricate process that requires skill and experience, especially when dealing with complex phenomena such as visual comfort. In order to facilitate this process, this paper provides two contributions: (1) the description of a new single-valued visual comfort measure, and (2) the application of the …
Dynamic Life Cycle Assessment Integrating Cultural Value, Ming Hu
Dynamic Life Cycle Assessment Integrating Cultural Value, Ming Hu
International Building Physics Conference 2018
Lack of spatial and temporal flexibility is a well-known limitation of current life cycle assessment (LCA). Exclusion of human and time consideration in LCA can also limit the potential of results. This paper explicitly proposes a dynamic life cycle framework and assessment model and demonstrated the potential importance of the method by integrating the cultural theory of risk. Cultural theory (CT) of risk was developed by anthropologist Mary Douglas and is originally a societal social anthropology approach based on the structure and functioning of groups within societies. Different society produces its own selected view of the natural environment, a view …
Passive Survivability In Residential Buildings During Heat Waves Under Dynamic Exterior Conditions, Timothy Aduralere, Jacqueline Isaacs, David Fannon
Passive Survivability In Residential Buildings During Heat Waves Under Dynamic Exterior Conditions, Timothy Aduralere, Jacqueline Isaacs, David Fannon
International Building Physics Conference 2018
The increased frequency of heat waves around the world has prompted numerous studies to improve building resilience and maintain thermal comfort in the face of extreme conditions. However, previous studies rely on the assumption of steady-state conditions, including external temperature, which limits real-world applicability, demanding a more practical perspective. This paper presents the use of recorded heat wave temperatures for a specified location to simulate the effect of extreme temperatures on the interior temperature of buildings when air conditioning is not used. The objective of this study is to determine how a building becomes uninhabitable during extreme heat and to …
Optimal Passive Design Strategies For Nearly Zero-Energy Dwellings In Different Chilean Climates Using Multi-Objective Genetic Algorithms, Daniela Besser, Frank U. Vogdt
Optimal Passive Design Strategies For Nearly Zero-Energy Dwellings In Different Chilean Climates Using Multi-Objective Genetic Algorithms, Daniela Besser, Frank U. Vogdt
International Building Physics Conference 2018
At present, most developed countries attempt to highly diminish the energy consumption of buildings towards nearly zero-energy performances. This study assesses passive design strategies by means of multi-objective optimizations with genetic algorithms, aiming to minimize the heating and cooling demand of typical single-family dwellings in Chile. The results show that the thermal transmittance and airtightness of the whole building envelope should be highly improved from the current limiting values in all assessed locations. Complementarily, strategies for managing overheating would be crucial for avoiding to shift the heating demand into cooling. With this regard, the use of thermal mass, natural ventilation …

Multiphysics Modeling Of Materials, Assemblies, Buildings And Cities, Jan Carmeliet, Jonas Allegrini, Aytac Kubilay, Dominique Derome
International Building Physics Conference 2018
There is growing evidence that heat waves are becoming more frequent under increased greenhouse forcing, associated with higher daytime temperatures and reduced night-time cooling, which might exceed the limits of thermoregulation of the human body and affect dramatically human health. Especially urban areas are affected, since these regions in addition experience an urban heat island (UHI) effect characterized by higher air temperatures compared to the surrounding rural environment. A necessary breakthrough is a shift away from a fragmented approach towards an integrated multiscale urban climate analysis. This type of research is a rather new domain of research and might be …

Studies On Novel Semiconductor Detectors And Front-End Electronics For Heavy Flavor Decay Studies, Gustavo Kertzscher
Honors Capstone Projects - All
I have studied novel semiconductor detectors designed to provide precise space point information of the trajectory of charged subatomic particles produced in high energy physics (HEP) collisions. The technological thrust aims toward maintaining good performance of these detectors in a hard radiation environment for an extended period of time. My studies approached two different types of silicon devices: a whole wafer comprised of test structures and pixel devices designed for the inner vertex detector of the BTeV experiment, and small test structures of a novel type of quasi-3D detectors developed in the context of the CERN RD50 collaboration. This collaboration …
