Keynote (Intermediate)
Indoor Environmental Modeling and Covid-19

William P. Bahnfleth, Ph.D., P.E., Fellow ASHRAE, Pennsylvania State University, State College, PA
The Covid-19 pandemic has focused attention on the importance of indoor air quality in a way that no prior event during the era of building performance simulation has done. In the search for good strategies to reduce indoor infection risk, many questions have arisen that in principle could benefit from indoor environmental modeling. This presentation considers the role modeling has played in responding to the pandemic, what issues that has raised about the current state of indoor air quality modeling, and what this experience suggests as aspirations and an agenda for future development of such tools.

LowDown ShowDown (Basic)
2020 ASHRAE LowDown Showdown

Taking a page from New York City’s groundbreaking new Climate Mobilization Act that requires building owners to reduce their carbon footprint, the 2020 LDSd challenges participants to design a new building that has a low carbon or carbon neutral footprint. This year the model building will be located in New York City. Participating Teams will design a 300,000 sf, 15 story mixed-use building located anywhere in the five boroughs. The building will contain retail space, residential space and a full-service restaurant.

Reorienting to Orientation

Track: Energy Performance and System Simulation
Many architectural texts refer to building-orientation as one of the first few decisions that impacts performance of buildings.
