This webinar will introduce the book ‘Building Performance Analysis’. This book is the second book that is endorsed by IBPSA. In the webinar, the author will give an overview of the content of the book, explain how it relates to the other IBPSA book, and provide some tasters of the deeper content of the work. The work provides a theoretical foundation for building performance analysis, explores different routes to analyse performance, and discusses how performance may impact the design, construction, and operation of buildings.

Pieter de Wilde is Professor of Building Performance Analysis at the University of Plymouth in the UK. He serves on the Board of IBPSA and is Chair of EG-ICE, the European Group for Intelligent Computing in Engineering. He is a Fellow of IBPSA and CIBSE, and member of ASHRAE.

The webinar provides an overview on human thermoregulation, thermal sensation and comfort perception. Influence factors and performance indicators for the assessment of thermal comfort in uniform and non-uniform environments are summarized. Comfort modeling and its use within the simulation environment is discussed at diverse levels of detail. We close the topic with the development and test of a new thermophysiological model implemented in the acausal modeling language Modelica. In this regard, we introduce a new type of comfort assessment system that can be used for the real-time assessment of local thermal comfort.

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.

Session-12: Integrated resource flow modelling of the urban built environment

by Darren Robinson

This webinar relates to chapter 15, on integrated urban resource flow modelling. After setting the scene, in terms of the rates and consequences of urbanisation and the associated need for models to support the formulation of policies, plans and strategies to mitigate adverse consequences of urbanisation, the nature of the integrated urban modelling challenge will be described. This will consider the range of principle urban systems to be modelled and the data and computational challenges that need to be overcome in this endeavour, as we strive towards the development of comprehensive and useful urban policy and planning decision support. Alternative urban building energy modelling strategies will then be described, placing particular emphasis on city-scale building energy modelling; comparing detailed microsimulation with the simulation of and extrapolation from building typologies.

Session-13: A view on future building system modeling and simulation

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 webinar, a repeat of a keynote talk that was given at IBPSA-England’s Building Simulation and Optimization 2016 conference, makes the case for why the world needs building simulation. It then describes what we as a community need to do to rise to the challenge, and argues the need for reforming the ways in which we teach BPS.

Building Simulation 2017: The Value of Energy Modeling to Owners and Architects

by Anica Landreneau

Anica Landreneau  
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.
