Andre Desjarlais & Michael Lubliner
Oak Ridge National Laboratory & the Building Science Advisor Tool
Energy efficient & moisture durable; building envelope solutions
Good Day and welcome to IAQ Radio+ episode 684. This week we welcomed Andre Dejarlais and Mike “Luby” Lubliner for a discussion on the Oak Ridge National Laboratory (ORNL), Building Science, and the new Building Science Advisor Tool.
Nuggets mined from today’s show:
Mike Lubliner: Change is hard. Mike has learned to embrace change by: learning from his mistakes, learning from his peers and learning from mentors such as: Andre Desjarlais, Joe Lstiburek and John Straub. Mike wants to pass the knowledge on to upcoming Building Scientists.
Andre Desjarlais: ORNL is one of 20 Dept. of Energy research laboratories. ORNL began as a bombs lab, transitioned to an energy efficiency lab in the 1970s and now among other things does research on making building envelopes more durable and efficient. ORNL develops new materials, and makes its unique facilities available for use by business and industry. ORNL is funded by both public and private sources. ORNL is working to reduce your monthly electric bills.
Andre Desjarlais:
ORNL History-
1938-1941- German physicists discovered nuclear fission and were working on weaponizing it. Germany annexed Czechoslovakia which had uranium ore. Albert Einstein (a known pacifist) after urging by other German scientists to wrote President FDR a letter to encourage the US to undertake similar research. The US declined and didn’t undertake nuclear research until Pearl Harbor was attacked and the US entered WWII.
1942- Tennessee Senator Kenneth McKeller a member of the Senate Approriations Committee was asked to hide $1 billion in his budget for the purpose of building super weapons. Senator McKeller asked “where in Tennessee would you like to hide it?”. TN was an ideal location due to TVA hydroelectric power and sparse population in the event of an accident.
1947-1980- Plutonium used in nuclear weapons. The ORNL reactor was copied after WWII to provide nuclear energy. Production of nuclear isotopes for nuclear medicine.
1970s- Oil Embargo ignited interest in building energy efficiency.
Some ORNL stats:
6000 people work at ORNL.
ORNL is home to the world’s fastest computer.
ORNL’s annual budget is $1.5 billion.
ORNL hosts 3000 visiting scientists annually, some for 2 weeks others for multiple years.
ORNL is focused on: computing, materials development & education.
Andre Desjarlais and Mike Lubliner:
Our parents’ homes with plaster walls and single pane windows didn’t have moisture or durability problems. When buildings are tightened-up problems can occur when the tightening isn’t done correctly.
Building Science Adviser online tool (BSA)- Stimulating Positive Change.
Builders are averse to charge. Change involves risks. The safe bet is to continue doing what you’ve been doing. You don’t grown and improve if you only take the safe bet.
Build confidence in using new building materials and more energy efficiency designs. The Building Science Adviser tool combines all of the info from: Building Codes, Field Experience and Computer Simulations. ORNL is working in tandem with the Building American Solution Center in Washington state other DOE labs.
The BSA is a web-based expert system which combines access to consultant and expert brains into an online tool. BSA provides guidance for both new and existing buildings.

ROUND-UP
Andre Desjarlais:
Any concerns about China or other foreign countries stealing or technology? - Security at ORNL and other government labs has been stepped up. Advance background checks, more security at facility entrances, etc.
It is the hope and desire of BSA that 3rd world countries adopt the technology and build more energy efficiently. Climate and building methods are different in North America than in Europe and Asia.
• Today is the 75th anniversary of the transistor.
• When the ORNL reactor was first started it was estimated that it would take 96 hours to go critical so scientists went home. Back then there no telephones and when the gauges started redlining, a car was sent around to the homes of the scientists to advise them what was going on.
Mike Lubliner:
BSA dials down to credible information and provides positive outcomes.
