About

The IBPSA-USA Research Committee promotes research activities in building performance simulation by advocating research outcomes, facilitating research exchange, and generating new research ideas and so on. There are currently three subcommittees:

Architectural Simulations Subcommittee

The major objective of the Architectural Simulations research subcommittee is to re-establish IBPSA as a “big tent” organization where various other applications of simulation in the buildings arena will have a dedicated platform. These areas include indoor air, lighting, acoustics, moisture, fire, and occupant flow, among others. This subcommittee seeks to elevate these key non-energy areas of interest, and will facilitate deeper cross-disciplinary discussions with researchers and practitioners in these areas.

Emerging Simulation Technology Subcommittee

The major objectives of the Emerging Simulation Technology research subcommittee are to identify and promote emerging hardware tools and software techniques in building simulation. It seeks to create awareness and promote use of emerging technologies within the research, industry, and government communities, and to facilitate interaction between these communities. The subcommittee takes special interest in high performance computing platforms, equation-based methods, and numerical methods suited to these platforms; however, it also seeks to identify new emerging technologies.

Urban Scale Simulation

Urban scale simulation is the modeling of resource consumption in multiple buildings or representative building types at geographic scales from the neighborhood up to the national level. The Urban Scale Simulation subcommittee aims to promote awareness and collaboration among practitioners, researchers, and other interested parties in the area of urban scale simulation. The subcommittee also provides input to IBPSA-USA in developing its broader research strategy as it relates to this specific area of building performance simulation.

Members

The research subcommittees are open to any volunteers interested in serving on them, and chair positions are open to IBPSA-USA members. Please contact us if you are interested in serving on one of the subcommittees.

Research Committee Presentations at Building Simulation 2017
August 7-9, 2017
San Francisco, California

The Research Committee presented three panel discussions at Building Simulation 2017.

Energy Modeling Output Framework; Improving Communication and Decision-Making presented by the Architectural Simulations Subcommittee. Building performance simulation reports are often unintelligible to the design team and the owner, reducing our ability to make better decisions. To address this impediment to energy efficiency, this panel convenes professionals from architectural and engineering firms to outline a process to clarify analysis intent and the expected simulation results. The result is Project STASIO.

Speakers:

Build Your Own Building Simulation Tool presented by the Emerging Simulation Technology Subcommittee. This panel discussion brings together building and urban simulation developers and accomplished users to discuss how they build tools and how you can build custom tools. When do we need customized tools? What skills and steps go into creating a trusted tool? How do tools become adopted by professions?

Speakers:

Urban Scale Modeling and Simulation for Smart City Connectivity, Sustainability and Resiliency presented by the Urban Scale Simulation Subcommittee. Buildings in cities consume 70% of electricity. Smart cities with innovative, optimized building designs and operations play a pivotal role in reducing GHG emissions and maintaining stable electric-grid operations. In this session, five speakers will present urban scale modeling and simulation projects to improve connectivity, sustainability and resiliency of cities.

Daylight Simulation: Research and Practice
October 3, 2016, 4:30-6:30 pm EDT
Room 518, Gund Hall, Harvard Graduate School of Design
48 Quincy St, Cambridge, Massachusetts

Daylight Simulation in Practice: As the building industry accrues a wide set of computational methods and metrics to evaluate daylight and glare, the useful application of these methods in design requires a more strategic mindset. The more methods that we establish, the more important it becomes to appropriately match them to the level of information known at the various stages of design. Here we will present the full range of techniques that we use to ensure daylight, visual comfort, and visual access to the outdoors at each phase of our process. Starting with simple direct sun and view studies in early design to identify suitable areas of the floor plan, we move gradually to more advanced glare and daylight autonomy simulations as we develop concepts for how occupants inhabit the space.

Daylight Simulation Research: Alstan will review five recent or ongoing research projects on daylighting and human-centric design: a new method for measuring and simulating trees, a conceptual design for active cooling in urban spaces, passive architectural design analysis in the tropics, the creation of a materials database for lighting simulation, and the development of new daylighting standards in Singapore.

Heliotropic Shading Daylighting a Rare Books Reading Room with Electrochromic Glass and Parametric Analysis: Re-purposing a long daylit atrium into a rare books reading room at Princeton University requires a high degree of solar control. After multiple iterations, the design team settled on electrochromic glazing, begetting the question of how to control over 900 tintable zones. Weissman developed an algorithm that allows the skylight to ‘follow’ the sun throughout the day and year, optimized to provide required shading for conservation criteria, and all while maintaining views. Perfectly tuned to its locale and adapted to the architecture, the pattern created by each scene state is a constantly evolving expression of the exact daylight-control needed at each moment.

Low­-Cost High­-Performance Building Simulation: Is that too good to be true?
June 28, 2016, 8-9:30 am CDT
ASHRAE Annual Conference, St. Louis

Building simulation can be used to help achieve energy efficient buildings. However, contemporary building simulation tends to be computationally intensive, which prevents building simulation from being widely applied in the real building process such as building design and operation. In this seminar, experts from both academic and industrial fields share how they improve the performance of different building simulations in terms of the computing demand and cost by taking full advance of cutting-edge computing technologies.

Simulation for Cutting-Edge Building Design
January 27, 2016, 11 am EST
ASHRAE Winter Conference

Cutting-edge simulation techniques have the power to expose design ideas that can radically reduce energy demands starting from an early point in the design process. However, integrating new simulation methods into existing design practices requires both creativity and depth of knowledge on the part of designers. This seminar brings together three experts from the industry to present how they have integrated advanced simulation techniques to increase energy efficiency, reduce resource consumption and further the design goals of a number of projects.
