Online Tech Session

Building Performance Simulation: What’s in the Black Box
Drury Crawley, Ph.D.

Over the last 50 years, building simulation has evolved into a powerful tool for evaluating the energy performance of potential or existing buildings. Building simulation allows easy comparison of the energy and environmental performance of many hundreds of design or retrofit options. This presentation provides an overview of building performance simulation fundamentals and history, Building Information Modeling, what’s in the black box of key simulation programs, as well as comparing underlying simulation methods. Because much of the data that building simulation tools require already exists in the BIM models, it’s critical that simple methods for sharing that data are available. This presentation also describes the opportunities and challenges for sharing data between BIM and SIM and demonstrates recent advances in data exchange.

He was elevated to ASHRAE Fellow in 2009 and achieved ASHRAE BEMP (Building Energy Modeling Professional) certification in October 2012. Recipient of ASHRAE Exceptional Service Award (2013), Service to ASHRAE Research Award (2012), Distinguished Service Award (2003), and Symposium Best Paper Award (1999) for “Which Weather Data Should You Use for Energy Simulations of Commercial Buildings?”

He is also active in the International Building Performance Simulation Association (IBPSA Vice President since 2018, at-large board member since 1998, Fellow in 2012, Regional Affiliate Liaison since 2006), IBPSA-USA (IBPSA-USA President since 2019, board member since 2013, vice president 2017-2019, treasurer 2013-2017), U. S. Green Building Council (USGBC, past vice chair and member, Energy & Atmosphere Technical Advisory Group; past member, Research Committee; past research Liaison), the American Institute of Architects (AIA), an Affiliate member of CIBSE, and serves on the editorial boards of three international Journals. He has written more than 125 papers and articles, testified before the U.S. Congress, lectured at more than 30 universities, and made more than 400 presentations on building energy efficiency, sustainability, and renewable energy throughout the world.

The Future of Refrigerants
Safe non-flammable low toxicity F-gases allowed for an exponential increase in the standard of living of society through increased food productivity, reduction in heat related deaths, increased worker productivity and migration of people to cities and to hotter climates.  Refrigerant safety was successfully maintained during the chlorofluorocarbon (CFC) refrigerant transition starting the 1990’s to lower ozone depleting refrigerants with the development hydrochlorofluorocarbons (HCFC’s) and hydrofluorocarbons (HFC’s) chemistries.  The orderly transition from CFCs to HCFCs and HFCs achieved a balance between the societal environmental demands for reduced ozone depletion while continuing to improve the standard of living in developing countries and minimize the societal safety impacts for everyone.

New societal environmental demands to control climate change are driving the development of new regulatory policies to restrict and lower the direct GWP (global warming potential) impact of F-gases.  These regulatory activities have driven significant refrigerant technology development activities globally as a result of climate change concerns.  Today designers are being asked to consider new lower direct GWP unsaturated hydrofluorocarbons (HFOs) refrigerants, some of which are slightly flammable under certain conditions, as well as revisiting the application of natural refrigerants, like carbon dioxide, ammonia, hydrocarbons and water.  This presentation will cover a brief history of refrigerants, how much refrigerants contribute to global warming, update the current regulatory situation, how to name and explain the new ASHARE 2L flammable classification and discuss the future challenges with the new refrigerants.  Insights will be shared into the impact on safety and other design considerations with the various refrigerants being proposed by application.
