III. Afternoon Agenda/Topics:  Building Science with Joe Lstiburek:

Introduction:

Key Concepts to be covered:
  • Changes to Building Technology
  • Why We Don't Build The Way We Used To
Building once was very easy.  Blocks and stucco and plaster and
concrete were known entities and trades knew how to build with them.
We didn't have problems until we introduced thermal insulation, EIFS,
paper faced gypsum board, high efficiency cooling systems and
"hollow" assemblies constructed out of steel studs.  The basic laws
of physics will be used in this section in conjunction with the
principles of geography and climate to explain the problems now
common in the building industry.

Biologicals and Indoor Air Quality:
  • Relative Humidity
  • Mold, Mildew, Fungi, Bacteria
  • Moisture Transport Mechanisms
Microbiological contaminants are at the most basic level a moisture
problem.  Solve the moisture problem and you solve the microbial
problem.  It only gets complicated when you realize that the
microbial contaminants can make you sick.  Once a building gets
contaminated you not only have to solve the moisture problem, you
also have to get rid of the contaminants.  The clean up is often much
worse than addressing the moisture problem.

Keeping the Rain Out of Buildings
  • Drainage Planes
  • Rain, Holes and Forces
  • Traditional Stucco, EIFS, and Brick Veneer
  • Face Seal, Barrier Walls, and Rain Screen
  • Pressure Equalization and Water Managed Systems
Rain control was traditionally accomplished with mass walls - masonry
sometimes several feet thick - that provided a "hygric" buffer.
Water was absorbed and released without damage to interior and
exterior surfaces.  Things changed when wall assemblies began to be
constructed out of water sensitive materials and were hollow and
filled with insulation or air.  This section will cover the
principles of rain control for "water managed assemblies".
  • Vapor Diffusion Retarders, Air Flow Retarders and
  • Roof/Attic Ventilation
Thermal Gradients and Condensing Surfaces
Difference Between Vapor Diffusion and Air Transported Moisture
Impermeable and Permeable Sheathings
Insulating and Non-Insulating Sheathings
The Only Reason You Vent in the South is the South Lost the Civil War

Where do you put a vapor barrier?  Isn't vinyl wallpaper a vapor
barrier on the wrong side of the assembly?  This section will address
the fundamentals of wall and roof design for the south.  How to
design walls to dry to both the inside and outside will be covered.
Material choices will be presented.

IV. Evening Reception on-site

BIOs:

Joe Lstiburek, B.A.Sc., M.Eng., Ph.D., P.Eng., is a principal of Building Science Corporation. He is a forensic engineer who investigates building failures and is internationally recognized as an authority on moisture related building problems and indoor air quality. Joe is the author of the Building Guide for Cold Climates. A concise, graphically rich technical manual, it contains over 150 detailed illustrations showing the latest details and techniques to effectively implement energy and resource efficient residential construction. EEBA's new guide embodies much of what is now known about building homes that are affordable, durable, energy efficient, healthy, safe, comfortable and environmentally responsible.

Sam Rashkin, ENERGY STAR Homes National Director, Environmental Protection Agency has managed ENERGY STAR for Homes since its launch in October 1995. Under his leadership, ENERGY STAR for Homes has grown exponentially to more than 2,500 builder partners and over 330,000 labeled homes. Currently, he is preparing to introduce a new EPA Indoor Air Quality label for the housing industry. Mr. Rashkin received his Bachelor of Architecture from Syracuse University; completed Masters of Urban Planning studies at New York University; and is a registered architect in California and New York. During his 20-plus years as a licensed architect, he specialized in energy efficient design and completed over 100 residential projects. He has also been responsible for developing and implementing market development programs at the California Energy Commission. Sam has prepared hundreds of articles, technical papers, reports, and seminars; contributed to numerous books; and has appeared on television and radio covering a wide variety of energy topics.
