Describes field measurements of thermal transmittance using portable guarded hotbox equipment on 2 types of concrete walls. Air leakage measurements of these same 2 types of concrete systems were made in the laboratory. Describes test methods. Illustrates measurement equipment and effects of infiltration diagrammatically. Concludes that it is not known how typical either wall system was, and further research is underway to evaluate other types of concrete building systems for air infiltration effects on thermal transmittance.
