Joseph Lstiburek

Joseph Lstiburek (, pronounced STEE-brek) is a forensic engineer, building investigator, building science consultant, author, speaker and widely known expert on building moisture control, indoor air quality, and retro-fit of existing and historic buildings.

Lstiburek is an adjunct professor of Civil Engineering at the University of Toronto; an industry consultant specializing in rain penetration, air and vapor barriers, building durability, construction technology, and microbial contamination &mdash; and an advisor on numerous prominent building envelope failures. He consults regularly on building code and industry standards.

Widely known for his "Perfect Wall" concept, Lstiburek identified four key control layers within the building envelope (rain, air, vapor, and thermal) critical to a building's behavior, long-term performance, and viability. He is a proponent of understanding the concepts that allow older buildings to survive over time in harsh climates &mdash; and mimicking those concepts with contemporary construction.

In 2001, The Wall Street Journal called Lstiburek "the dean of North American building science."

Early career
While working towards his bachelor's degree, Lstiburek also worked as a residential construction manager for Product Design Development Corporation. After graduating he became president of Inertia Development Corporation, a company that built and tested twenty low-energy houses.

He went on to work for the Housing and Urban Development Association of Canada (HUDAC) from 1981-1982 where he was involved in the Canada-wide Super Energy Efficient Housing R-2000 program and became the Director of Research.

While studying for his master's degree, he worked at the University of Toronto Centre for Building Science and later served as president of Building Engineering Corporation, a building sciences and components company in the residential construction industry. He also briefly worked in the commercial construction industry as a senior engineer for Trow in Toronto.

After receiving his master's degree, Lstiburek worked in the United States as a consultant with Dames & Moore, a Chicago-based engineering consulting firm specializing in building sciences and construction technology.

In 1990 Lstiburek became a principal at Building Science Corporation.

Recent career
In the 1990s, Lstiburek worked with Pulte Homes to reduce utility costs of their residences by 30% without increasing construction cost or changing their size, shape or look. Lstiburek suggested five changes, and the prototype home subsequently received Nevada's home energy Five Star rating.

In 2005, with Hurricane Katrina's inundation of New Orleans, Lstiburek noted that significantly more older, elevated homes constructed with traditional, water-tolerant methods (masonry and plaster, without cavity insulation) would be able to return to service after the storm &mdash; than homes with typical newer construction (gypsum wallboard, insulation-filled cavity)." Lstiburek recommended that future flood-prone construction learn to mimic traditional drainable, dryable, water-tolerant materials.

In 2007, at MIT's Stata Center (subject of lawsuits of the building's architect and contractors), Lstiburek had observed problems during construction, noting that the building envelope's key control layers (rain, air, vapor and thermal) &mdash; were in the wrong order, causing the building to soak in its own condensation ("like your T-shirt gets sopping under a leather jacket"), causing erosion of building materials and mold, as well as causing the building to "smell like dirty socks." Lstiburek noted that "basic errors like these occur in up to 20% of all new buildings going up" from simple buildings to "soaring landmarks."

Lstiburek has been involved in the development of standards and industry resources by U.S. government agencies. He is the principal investigator for the Building Science Consortium, an industry group in the U.S. Department of Energy (DoE)'s Building America Program that encourages the development of energy efficient innovations in the homebuilding industry. He participated in a 40-city seminar tour of the United States for the EPA and BOMA. Lstiburek authored the DoE handbook on moisture control and was a special contributor to the EPA's "Building Air Quality: A Guide for Building Owners and Facility Managers."

Lstiburek is a regular speaker and presenter at industry events. He appeared on the PBS Nova program entitled "Can Buildings Make You Sick?" featuring his work on the Registry Building in Boston, MA. Lstiburek writes regularly for industry publications and has published a number of books.

In 2008, Lstiburek contributed to an article written for ASHRAE raising doubts about efficiency claims of LEED certified commercial buildings &mdash; a points-based, third-party verified industry measurement standard for building sustainability. Lstiburek, along with fellow building scientists, challenged the statistics on LEED buildings as well as comparisons used in a 2007 (and updated 2008) New Buildings Institute report. Lstiburek urged the industry to emphasize real-world, actual energy savings rather than "chasing points."

Recognition
In 2009, Lstiburek was nominated for the Hanley Award for contributions to the advancement of sustainable housing in the United States.

In 2007, the Energy & Environmental Building Association (EEBA) awarded Lstiburek a Legacy Award for the development of building performance and the science of new home construction.

In 2004, Lstiburek became an ASHRAE Fellow.

In 2000/2001 Lstiburek received an Anthony A. Woods Award, given by the Ontario Building Envelope Council (OBEC) for contributions to the design, construction and performance of the building envelope.

In 1994, the Energy & Environmental Building Association (EEBA) awarded Lstiburek a design award for his joint design effort with architect and business partner Betsy Pettit for an affordable Dallas development of heavy-insulated three-bedroom homes, maximizing solar gain, natural light and shade as well as providing appropriate ventilation.

In 1992, the Energy & Environmental Building Association (EEBA) awarded Lstiburek an Award for Technical Merit.
