Built to Withstand: Eco-Friendly Construction for a Changing Southwest

The Southwest's arid climate presents unique challenges: wildfires, pests, mold, haboobs, and more. In this diverse environment, building materials must offer more than structural support—they must provide resilience. Sustainable building is essential for long-term durability and safety.​ 

For example, in California, as Los Angeles communities rebuild, construction industry experts are showing renewed interest in natural buildings that use less flammable materials. Homeowners are seeking homes that burn less easily and release fewer toxins into the air. 

As Los Angeles County Fire Chief Anthony Marrone has been telling residents, “We must manage the wildfire ecosystem…but we really need to start with structure hardening.”

1. MgO Solutions: Built for fire, mold, pests–and more

In the Southwest, wildfires are a yearly reality. Climate change only heightens the risks, adding invasive pests, mold outbreaks fueled by moisture intrusion, and extreme weather to the mix.

ZS2 Technologies' TechPanels™—made with advanced magnesium oxide (MgO)—offer a powerful response. These panels provide robust fire resistance and can withstand high temperatures from fast-moving flames. 

But the innovation doesn’t stop at fire. TechPanels™ are moisture-resistant, mitigating mold growth in humid or post-storm conditions. They naturally deter termites and pests due to their inorganic composition. Engineered to endure wind uplift and high-impact weather–including haboobs and coastal hurricanes– TechPanels™ redefine what it means to build resiliently.

2. Coatings and Sheathing: Preventing problems before they start

Mold and mildew flourish in hidden places—behind walls, beneath surfaces, wherever moisture lingers. ZS2’s TechBoards™, also made with MgO chemistry, resist moisture absorption far better than traditional gypsum boards. This makes them ideal in areas prone to humidity, storms, or hurricane-driven rains.

Their dense, non-porous surface blocks microbial growth, contributing to healthier indoor air quality–something increasingly critical as public awareness grows around building-related illnesses.

3. Steel and Sustainability: Holding strong against pests and pressure

Framing serves as the skeleton of any structure. When pests infiltrate, integrity weakens. Unlike wood, cold-formed steel framing won’t rot, warp, or fall victim to termites. These steel frames complement MgO systems, creating a strong, pest-proof, and mold-resistant envelope.

Additionally, cold-formed steel enables more precise and airtight construction, improving energy efficiency and aligning with SBS’s mission to reduce the carbon footprint of the built environment.

4. ADUs: Compact, resilient, and future-forward

Across the Southwest, Additional Dwelling Units (ADUs)—casitas, or in-law suites—are reshaping the residential landscape. These small, independent structures offer flexible living solutions for multigenerational families, aging parents, or rental income. But in regions where the land is harsh and the weather unpredictable, ADUs must be built with intention and innovation.

ZS2 Technologies’ MgO-based panels and sheathing systems bring full-spectrum protection to ADUs: fire resistance in wildfire-prone areas, mold prevention for humic climates, and pest deterrence in termite-heavy zones. Their light weight and strength also allow for quick installation on tight urban lots or rural terrain.

SBS ensures every ADU project meets or exceeds evolving green building standards–like California’s CALGreen Code and similar environmental benchmarks being adopted across Arizona and Nevada, helping communities grow sustainably and safely.

Leading the way in sustainable construction

Innovation in construction isn’t just about sleek design—it’s about adapting to a changing climate and protecting communities for generations to come. Across the Southwest, forward-thinking architects, builders, and developers are leading the charge.

At SBS, decarbonization is a core value. Every MgO board, steel frame, and system solution is part of a bigger commitment–to reduce waste, lower emissions, and fortify homes for the climate realities of today and tomorrow.
