IBPSA University is happy to present one of the best entries of BS2019 Student Modelling Competition titled ‘PENTATHLON’. Four students from Free University of Bolzano & University of Trento will explain their entry during upcoming webinar. As part of the 16th IBPSA International Conference and Exhibition IBPSA organized a student modelling competition. The aim was to facilitate wider participation in the conference and to provide a competitive forum for student members of the building simulation community. IBPSA Newsletter Volume 29 No 1 and http://buildingsimulation2019.org/competitions contains more information about the competition.

The competition is set up as a simulation pentathlon and consists of:

1. Model and simulate the existing building;
2. Assess the buildings energy consumption and indoor environmental quality;
3. Redesign using retrofit measures to enhance the building’s performance;
4. Assess the building daylighting performance and visual comfort;
5. Optimize the building performance using previously assessed performance measures, parametric design, sensitivity analysis or multi-objective optimization.

The team vision to accomplish these five contests is to attempt the improvement of the performance of the palace, while also preserving as much as possible its artistic heritage. This has been possible implementing an optimization process that other than minimizing the energy consumption and maximizing the indoor environmental quality, minimize also the architectural impact of the retrofit. Moreover, to be consistent with the cost optimality approach suggested by the European Energy Performance of Building Directive (EPBD), the students used the net present value to guide the choice of the optimal retrofit among the Pareto front resulting from the optimization.

Jason Brown  
This webinar introduces a new approach to performance-based building design. We will first have an overview of the complex, iterative, and uncertain nature of building design and establish requirements for integrated design-and-energy- decision making. We then propose a novel systematic data-driven method, based on linear inverse modeling, that generates plausible ranges for design parameters given a preferred energy target. The application of the proposed method in a case study shows that it is capable of helping designers/users make informed decisions regarding energy performance iteratively and confidently at the early stages of building design.

Roya Rezaee is co-director of Energy Lab at Perkins+Will. She has a PhD. in High-Performance Building, with an expertise in design and different areas of building technology including energy performance, daylight performance, parametric design, building information modeling (BIM), model-based system engineering, risk assessment, and data analysis in building performance prediction.

How can we choose the building performance simulation software that helps its users make the best decisions? This webinar explores the psychology of simulation users interacting with two similar simulation tools and tracks the different patterns of design exploration, outcome, and user satisfaction that result. It focuses on the importance of accurate real-time feedback to enhance the abilities of designers and building analysts. In a study, 40 subjects with backgrounds in building design and technology completed two shading design exercises to balance glare reduction and annual daylight availability in two open office arrangements using two simulation tools with differing system response times, AcceleradRT and DIVA-for-Rhino. Subjects with access to real-time simulation feedback tested more design options, reported higher confidence in design performance and increased satisfaction with the design task, and produced better-performing final designs with respect to spatial daylight autonomy and enhanced simplified daylight glare probability.

Session-7: Learning the fundamentals of building performance simulation through an experiential teaching approach

Ian Beausoleil-
It is relatively easy to train architects and engineers to operate BPS tools and to produce results, but there is considerable evidence to show that it is quite difficult to produce accurate results, even for experienced users. I believe that BPS suffers from a credibility gap and that its full potential will only be realized once we adequately prepare users to effectively apply tools with full knowledge of their applicability, modelling limitations, and default methods and data, and provide them the skill set to scrutinize their results. An experiential approach for teaching the fundamentals of BPS through a learning spiral composed of four modes of learning has been devised. The approach and the learning outcomes that have been achieved through each of the learning modes will be demonstrated in this webinar through examples extracted from the teaching of a semester-long post-graduate course.

Ian Beausoleil-Morrison is a Professor in the Faculty of Engineering and Design at Carleton University in Ottawa (Canada), where he heads the Sustainable Building Energy Systems laboratory. He is co-founder and has been Co-Editor of the Journal of Building Performance Simulation since its establishment in 2008.

About Webinar: For energy analysts, one of the most difficult challenges is condensing a great deal of data into an intelligible format so architects can understand it. For architects, one of the challenges in working with analysts is not knowing what performance-related questions can be asked and answered. A solution that connects both of these is IBPSA USA’s Project Stasio, a crowd-sourced, a public website that connects performance questions with graphics from simulation outputs that succinctly answers the question. This webinar will offer insights into Project StaSIO!

This webinar builds on chapter 14 of the Hensen and Lamberts book and offers a treatment of the role of building automation and control strategies in the context of building performance modeling. In particular, we motivate the use of models for the advanced control of building energy systems by offering application examples employing both simple and more sophisticated building and system models for both instantaneous and predictive optimal control applications. In particular, we present the model development, calibration, and reduction process applied to any linear time invariant building energy problem using lumped parameter analysis and state space representation illustrated in the context of a low-level model predictive control task. Further, we will introduce a taxonomy of control model categories, which have been applied to a range of demand side flexibility studies including price responsive control of commercial buildings for price arbitrage, demand flexibility of commercial buildings for automatic demand response, residential building distributed MPC for feeder load shaping, and integrated end-to-end modeling of electric generation and load to assess the value of load flexibility in both a residential and a commercial context. Several application examples will be reviewed as part of the webinar.

Buildings and community energy systems continue to require increased performance, provide services to the grid, and facilitate the integration of renewable energy and waste heat sources, while providing better comfort. Consequently, their energy and control systems are becoming more integrated and complex. Arguably, current building simulation programs have not been designed with these new and emerging requirements in mind. This talk therefore present technologies and open-standards that are well positioned to address these new challenges. It will explain underlying principles for modular modeling that allows reasoning about the system as well as formal manipulations of the model to address different applications, ranging from design to verification and operation of building systems.

This talk described how HOK tracked both modeling costs and predicted energy savings for a selection of it projects over the course of several years. The results showed that energy modeling payback is typically one to two months. The cost of even extensive modeling is a fraction of the annual energy cost of a typical large building so it can pay for itself very quickly. (courtesy: IBPSA USA)

Building Simulation 2017: The Challenge of Simulating Airflow in Buildings: Lessons from Oceanography to Aerospace

by Paul Linden

Anica Landreneau  
The challenge of simulating airflow in buildings comes from the unique combination of complex geometry and boundary conditions and the intrinsic dynamics of the air flow, particularly when buoyancy force and convection are important – as they often are. The talk illustrated this challenge by describing the basic types of ventilation flows and presenting different methods to simulate them. In particular, the possibilities and limitations of various simulation techniques discussed and some outstanding issues in airflow simulation described, together with some recent laboratory experiments and simulation results.
