The Invisible Force Holding Our Buildings Back

Why aren't we building as well as we could be? The answer does not lie in a lack of technical knowledge, but in our deeply held beliefs about our place in the world. As the brilliant systems thinker from the MIT Systems Dynamics group, Donella Meadows, teaches us, our "paradigms" or worldviews are our most powerful levers for change.

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.

The Collaborative Legacy of Lake|Flato Architects and Positive Energy

The landscape of contemporary architecture is increasingly defined by the synergy between visionary design and rigorous building science. At the forefront of this evolution stands the enduring partnership between San Antonio based Lake|Flato Architects, renowned for their distinctive, context-responsive designs, and Positive Energy, an Austin, TX-based residential MEP engineering and building science firm. For over a decade, our collaboration has consistently yielded award-winning projects, particularly within the challenging environmental contexts of the Texas Hill Country and beyond. This blog post explores how our integrated approach to design has not only created beautiful and award winning architecture, but also offers invaluable lessons for the broader architectural community.

The Campsite at Shield Ranch

The Campsite at Shield Ranch was designed by our friends at Andersson / Wise. It is a 100% off-grid community designed to engage and celebrate the natural context of the ecologically diverse 6800-acre hill country sanctuary where it sits. The camp features an open-air pavilion, screened shelters, and miles of hiking trails just 22 miles from downtown Austin. Positive Energy was hired to perform MEP engineering, solar design and engineering, and Resilient Systems consulting. The Resilient Systems we master planned for the program include a 64kW architecturally integrated solar array, a 200kWh (100kW peak power capacity) backup battery array, a 60kW emergency propane genset, and we consulted with another rainwater system engineer a couple of 60k gallon rainwater collection tanks for occupancy use with TECQ compliant filtration for public consumption (as well as necessary rainwater storage for fire suppression).
