A Path for California Architects to Easily Achieve Title 24 and Achieve Beyond-Code Performance

California has long been at the forefront of energy efficiency in the United States compared to its 49 counterparts, with its pioneering Building Energy Efficiency Standards, commonly known as Title 24, Part 6, first adopted in 1976. These standards are not static. They undergo rigorous updates every three years, serving as a dynamic benchmark for building energy performance and a critical mechanism for reducing greenhouse gas emissions during construction and operation. This continuous evolution is a deliberate policy strategy by the California Energy Commission (CEC) to systematically integrate the latest energy-saving technologies and construction practices into the built environment.

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.
