#385 Bonny Gray on Revolutionary Water Systems, Building Re-Use, and the Future of Prefab Construction

The Green Impact Report Quick take: Quick take: LEED Fellow Bonny Gray reveals how she built the world’s largest cistern under a parking garage, battles “LEED-like” terminology that’s undermining green building credibility, and why prefabricated construction might be the key to scaling sustainability.

Meet Your Fellow Sustainability Champion

Bonita Tice Gray, AIA LEED AP BD+C, is Director of Sustainability and Quality at Method Architecture and a 2022 LEED Fellow—the green building industry’s most prestigious professional designation.

Selected as one of only 20 distinguished green building professionals worldwide, Bonny has made exceptional contributions to sustainability in Texas over her decade-plus career.

Her achievements include administering diverse LEED and Austin Energy Green Building projects, serving as Author/Liaison for SXSW Eco from 2013-2016, and leading as USGBC Central Texas Co-Chair. She created the LEEDv4 Green Associate Professionals class and authored the Texas Green School Symposium.

Starting her journey in Iowa farm country with a coal-heated 1916 home, Bonny discovered her passion for architecture walking through the beautiful red brick Architecture Hall at University of Nebraska—where she was one of only two women in her graduating class.

Breaking Ground on Better Building

In this episode, Bonny Gray revolutionizes traditional construction approaches:

Key Insight #1: Massive water capture systems can solve regional scarcity challenges

The Challenge: Texas faces severe water scarcity, forcing buildings to compete for limited municipal resources
The Solution: Bonny designed the world’s largest cistern underneath a parking garage at AMD’s campus, capturing all roof and site water runoff for irrigation and cooling tower systems
ROI: This butterfly-roof design with integrated water management eliminated municipal water dependency while creating a replicable model for water-stressed regions

Key Insight #2: “LEED-like” terminology undermines legitimate green building credibility

The Challenge: Developers use “LEED-like” language to appear sustainable without third-party verification or actual performance standards
The Solution: Bonny advocates for clear binary thinking—you either have a LEED-certified building or you don’t, with no middle ground
ROI: Eliminating misleading terminology protects building owners from greenwashing liability while ensuring they capture actual energy savings and operational benefits

Key Insight #3: Prefabricated construction is the next frontier for sustainable building

The Challenge: Traditional construction creates massive waste streams and unpredictable carbon footprints
The Solution: Bonny champions pre-assembled facades, 3D-printed buildings using carbon-negative concrete, and manufactured housing approaches with precise material planning
ROI: Prefab reduces construction waste to near-zero, enables exact carbon accounting, and scales sustainable practices faster than traditional building methods

Sustainable Soundbite

Your Green Building Action Plan

Transform your next project with these steps:

This Week: Audit your current projects for misleading “green-like” or “LEED-like” language. Replace with specific, measurable sustainability claims or pursue actual certification.
This Quarter: Investigate water capture opportunities on your sites. Calculate potential cistern capacity and irrigation offset for your climate zone using Bonny’s butterfly roof approach.
This Year: Explore prefabricated building components for your next project. Research local manufacturers offering sustainable pre-assembled facades or investigate modular construction options that reduce embodied carbon.
