Cummings, J. B.; Withers, C. R. (Energy System Laboratory (http://esl.tamu.edu), 2008-12)In a hot and humid climate such as Florida, “snowbirds” that leave their homes for extended summer periods need guidance on effective and energy efficient methods of humidity control. Experiments were performed in seven ...

Cummings, J. B.; Withers, C. R. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2000)Suspended t-bar ceilings are common in commercial buildings. Research has found that these ceilings are very leaky, and several problems arise from this. If the space above the ceiling is vented to outdoors, the entire ...

Withers, C. R.; Cummings, J. B. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2000)Recent research over the last few years is providing a better understanding about the building envelope of small commercial buildings. These buildings have very similar construction to single family residential buildings, ...

Cummings, J. B.; Tooley, J. J.; Moyer, N. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1990)Testing for duct leakage was done in 155 homes. Tracer gas tests found that infiltration rates were three times greater when the air handler was operating than when it was off. Infiltration averaged 0.85 air changes per ...

Moyer, N. A.; Cummings, J. B.; Chasar, D. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2002)Increasing enrollment in grades K-12 coupled with the spiraling costs of construction has pushed school boards to develop more cost-effective classrooms, from the perspective of initial cost, longterm energy consumption, ...

Withers, C. R. Jr.; Cummings, J. B. (Energy Systems Laboratory (http://esl.tamu.edu), 2010-08)Wind washing is a general term referring to diminished thermal control caused by air movement over or through a thermal barrier. The primary focus of this paper is towards a specific type of wind washing where wind can ...

Cummings, J. B. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1989)A methodology is presented for using tracer gas testing to detect and quantify duct leakage in homes. Since air is invisible, leakage of air from duct systems often remains undetected. Smoke sticks used in conjunction with ...
