Our home was built with a large portion of the south wall constructed as a unvented Trombe Wall. Usually a Trombe wall is depicted with vents to move the air through the wall but it turns out an unvented system has a proven track record. I’ve encountered a few nay-sayers to the Trombe wall concept but the information I’ve gathered about performance outweighs the arguments against the concept. Here is some of my research on the subject.
The most convincing paper took data from the Los Alamos experiments in the 1970’s and applied modern computer modeling with positive results for the effectiveness of a Trombe Wall system.
