One of the largest contributors to energy waste in a building is heat loss or gain through walls, roofs, doors and windows. The energy efficiency of the building envelope is a major consideration in an analysis of it’s lifecycle costs. The mass of an internally insulated concrete tilt-up wall panel makes it a significant thermal reservoir having the ability to store a large amount of heat energy.
During the heating season, an internally insulated concrete tilt-up wall panel will absorb interior heat during the day, radiating the warmth back into the building’s interior during the night, the same principal in reverse holds true during the cooling season. An internally insulated concrete tilt-up wall, by storing and later releasing the energy needed for heating or cooling, delivers year-round energy benefits. The session will be an in-depth look into how an internally insulated concrete tilt-up wall can greatly improve the energy efficiency of the building envelope.
James Baty, Technical Director at Tilt-Up Concrete Association
James Baty is a partner at Sauter Baty Associates in Mount Vernon, Iowa and currently serves as Technical Director for the Tilt-Up Concrete Association. Combined with his degree (BARCH) in Architecture from Iowa State University, Mr. Baty has added a career long emphasis on thermal design efficiency and concrete construction. From 1991-2001 he served Thermomass as Technical Services Manager where he was responsible for the integration of thermal efficiency with commercial construction through engineering, design consultation and construction supervision. Since 2001, he has served the global tilt-up industry as TCA Technical Director providing guidance to both members and general industry for design, construction and performance aspects of buildings incorporating tilt-up construction. He presently serves as a primary educator to the industry and a certification examiner for the ACI/TCA Certified Tilt-Up Supervisor program. Mr. Baty has developed thermal design and engineering tools including isothermal planes analysis programs and implementation programs demonstrating the benefits of mass construction as referenced in ASHRAE 90.1. His research has involved the use of thermal modeling programs for energy-efficient design such as VisualDOE, Physibel and other mechanical engineering programs. Mr. Baty has also contributed to full-scale thermal testing of insulated concrete sandwich panel constructions with the U.S. Department of Energy (DOE) at Oak Ridge National Laboratory (ORNL). He has also been part of a research team for the performance of residential concrete foundation placements during cold weather and co-author for the resulting research report from the Concrete Foundations Association.
