Positive Energy's Education and Advocacy Efforts

Our comprehensive approach to MEP engineering and building science consulting is deeply rooted in a strategic vision that extends far beyond individual project delivery. Our commitment to the idea of "Healthy people, healthy planet” is unwavering. It is not just a statement, but a guiding principle that permeates our extensive education and advocacy efforts. Through the firm’s Building Science Blog and The Building Science Podcast, we aim to actively cultivate knowledge everywhere we can, demystifying complex technical concepts like indoor air quality and intricate wall assembly dynamics for architects and the broader industry. This accessible knowledge transfer empowers architects to confidently integrate advanced building science into their designs, mitigating risks and ensuring the long-term performance and durability of their projects.

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.

Marfa Ranch

The Marfa Ranch is a distinguished residential project by Lake Flato Architects, is thoughtfully situated on a low rise within the expansive, pristine desert grasslands of Marfa, Texas. This unique location, nestled between the Chihuahuan Desert and the majestic Davis Mountains, presents a challenging yet profoundly beautiful environment. The architectural design of the ranch consciously adopts a low profile, comprising eight distinct structures meticulously organized around a central courtyard. This layout, shaded by native mesquite trees, serves as a cool respite from the sun-drenched desert beyond its walls, drawing inspiration from the area's earliest regional architectural traditions. Architect Bob Harris of Lake Flato articulated that the design embodies a "deliberate quality of spareness that matches the qualities of the land," emphasizing the importance of the house maintaining a low profile to merge seamlessly with the terrain while simultaneously opening to distant views and providing crucial protection from the region's harsh winds and intense sun. This project has garnered significant recognition, including the 2022 Texas Society of Architects Design Award and its inclusion in Dezeen's Top 10 Houses of 2022.
