Ms. Landreneau is a Principal and Global Sustainable Design Director of the architecture firm HOK, and she leads their sustainable discipline and consultancy practice. Anica serves on HOK’s Board of Directors and Design Board, and is a past member of the Management and Marketing Boards. She co-authored The New Sustainable Frontier: Principles of Sustainable Development with the U.S. General Services Administration.
Anica is an advocate for the use of simulation in design, and considers it critical to HOK’s mission. Her talk will describe 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.
Professor Linden is the G.I. Taylor Professor Emeritus of Fluid Mechanics and Director of Research in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge and is also the Blasker Distinguished Professor Emeritus of Environmental Science and Engineering, Department of Mechanical and Aerospace Engineering, UC San Diego.
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 will illustrate 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 will be discussed and some outstanding issues in airflow simulation described, together with some recent laboratory experiments and simulation results.
