BSD-109: Pressures in Buildings by Joseph Lstiburek — last modified 2008/08/20

Air flow in buildings is one of the major factors that governs the interaction of the building structure with the mechanical system, climate and occupants. If the air flow at any point within a building or building assembly can be determined or predicted, the temperature and moisture (hygrothermal or pyschometric) conditions can also be determined or predicted. If the hygrothermal conditions of the building or building assembly are known, the performance of materials can also be determined or predicted

BSD-119: Summer Condensation Problems in Ice Arenas by John Straube — last modified 2008/08/20

Ice rinks and arenas are a common building type in many communities. The trend over the last 25 years has been to operate these arenas for greater periods of the year, often throughout the summer. Also, an increasing number of such buildings are being built in areas with warm, humid summer weather. The result has been an increase in the number of reported moisture problems, most of which revolve around summer condensation. This digest will describe the causes and discuss potential retrofit solutions for summer condensation in ice arenas.
