How to Solve High Humidity in Home in Winter

This is a story about high humidity in Alex's new home in winter. The house is located in Rockville, MD. Despite numerous consultations with experts, the problem persisted, causing discomfort and energy inefficiency.
The host, an experienced energy auditor, was approached to help resolve this "Dew Point Dilemma." Through a detailed inspection involving an energy audit and the use of cutting-edge technology, the host uncovered several issues contributing to the problem, including poor insulation, unsealed air leaks, and a significant temperature clash near a bay window that led to excessive condensation.
The resolution involved upgrading insulation, sealing air leaks, bridging the temperature gap, and reducing indoor humidity levels, aligning with recommendations from Energy Star and Pepco. This comprehensive approach led to a remarkable transformation in the home's comfort and energy efficiency, resulting in a 43% reduction in air leakage and about a 40% decrease in gas usage compared to the previous year.
The episode highlights the importance of perseverance, technology, and professional audits in solving home comfort issues, encouraging listeners facing similar problems to seek a professional energy audit.
