A Building Science Dive into the Hill Country Wine Cave

The Hill Country Wine Cave, a distinctive architectural endeavor by Clayton Korte Architects, is intricately integrated into the natural landscape of the Texas Hill Country. This private subterranean structure is carved into the north face of a solid limestone hillside, designed to nearly vanish into its surroundings. Completed in 2020, the 1,405 square meter facility encompasses a tasting lounge, a bar, a restroom, and a dedicated wine cellar capable of storing approximately 4,000 bottles.

The Case for Dedicated Dehumidification In Sealed Attics

Modern building design increasingly embraces sealed attic construction as a strategy to enhance energy efficiency and improve air leakage control, particularly beneficial for the performance of HVAC ductwork. This approach, where the attic space is brought within the building's thermal and air control envelope, fundamentally alters the moisture dynamics compared to traditional vented attics. While offering significant advantages, sealed attics introduce unique moisture challenges that demand precise and active management to prevent long-term durability issues and maintain superior indoor air quality.

Rethinking Moisture Control: The Primacy of Air Tightness Over an Outdated Fixation on Vapor Barriers in Building Envelope Design

For decades, the architecture and construction community has engaged in a persistent debate surrounding the role and necessity of vapor barriers in building envelope design. This discussion, while touching on critical aspects of moisture control, has often been characterized by an overemphasis on the ability of specific materials to resist vapor diffusion, sometimes to the detriment of addressing more significant moisture transport mechanisms. Within the building science community, however, the principles governing moisture movement are largely considered settled science. It is well-established that air leakage, rather than vapor diffusion, is the predominant pathway for moisture transport through most wall assemblies.
