We are thrilled to announce Prof. Dr.-Ing. Andreas H. Holm as the opening keynote speaker for PhiusCon 2021!

Dr. Holm is a professor of building physics who currently serves as the Institute Director of the Forschungsinstitut für Wärmeschutz e. V. Munich (FIW Munich). He began his professional career 25 years ago, during which he has served as group leader in the department of hygrothermics responsible for the development of WUFI and was head of the “Indoor Environment” department within Fraunhofer-IBP.

He is chairman of the DIN committees “Thermal Insulation Materials” and “Structural Heat Protection in Building Construction,” as well as the International Standards Committee “Thermal Approach to Materials and Products” and “Test and Measurement Methods.”

During his keynote address, Dr. Holm will explore the wide range of economic consequences and opportunities in Germany since the country’s swift shift in policy related to environmental protection and fossil fuels and what a similar shift could mean for the United States. His expertise in building materials and building science make him the ideal person to discuss a topic that Jeremy Rifkin explored in 2019 as the conference’s keynote speaker and originally introduced in his book titled “The Green New Deal: Why the Fossil Fuel Civilization will collapse by 2028, and the Bold Economic Plan to Save Life on Earth.”


Technical Keynote: Julie Klump

Julie Klump_smWe are excited to announce that environmental design expert Julie Klump will be delivering the Friday technical keynote address!

Julie is Vice President for Design and Building Performance, responsible for design and energy efficiency for development projects and the owned portfolio. She assists POAH in the acquisition process with building investigation, energy budgeting, scope development and cost estimates. She works with POAH’s Development Project Managers and Asset Managers to engage the project team (architect, engineer, clerk, etc.) for rehabilitation of new acquisitions and/or POAH owned properties (including the implementation of energy efficiency programs). For new construction, she oversees design development and construction, integrating green and sustainable design. Julie authors POAH’s product and performance specification used by development and maintenance staff when selecting building materials and components. Additionally, she manages the data collection and analysis that define the efficiency efforts and serves as a subject matter expert for all aspects of building performance.

A Certified Passive House Consultant (CPHC®) and LEED-certified architect with an undergraduate degree in environmental design, Julie has worked as an architect, construction manager, owner’s project manager and Executive Director of the Texas Historical Foundation.

A graduate in Environmental Design from Texas A&M University, Julie received her Master of Architecture degree, with Certification in Historic Preservation, from the University of Texas at Austin. She has completed special studies in Art and Architecture in Florence, Italy and in Preservation/Restoration in Sebastopol, Crimea

The closing keynote speaker for PhiusCon 2021 will be none other than Dr. Joseph Lstiburek!

Joseph Lstiburek is the founding principal of Building Science Corporation. Dr. Lstiburek’s work ranges widely, from providing expert witness testimony to overseeing research and development projects, to writing for the ASHRAE Journal and buildingscience.com. Dr. Lstiburek’s commitment to advancing the building industry has had a lasting impact on building codes and practices throughout the world, particularly in the areas of air barriers, vapor barriers, and vented and unvented roof assemblies. For example, his work with industry partners through the Department of Energy’s Building America program led to significant research into the wetting and drying of walls and ultimately to a major code change relaxing the requirement for vapor barriers in the International Residential Code.

Dr. Lstiburek is also an acclaimed educator who has taught thousands of professionals over the past three decades and written countless papers as well as the best-selling Builder Guides. Fittingly, the Wall Street Journal has described him as “the dean of North American building science.” He has a joy for telling tall tales to his protégés and audiences.

Dr. Lstiburek holds a Bachelor of Applied Science in Mechanical Engineering, a Master of Engineering in Civil Engineering, and a Doctor of Philosophy (Ph.D.) in Building Science. While still an undergrad, Dr. Lstiburek worked as a residential construction manager; during his Master’s degree, he developed the Air Drywall Approach to air barriers. Other formative experiences include working on the Canada-wide Super Energy Efficient Housing R-2000 program and serving as senior engineer on commercial construction projects for Trow in Toronto. Dr. Lstiburek founded BSC in 1990 with his business partner Betsy Pettit, and he has been a key figure in establishing BSC as one of the most influential, innovative, and respected building science firms in North America.
