Sustainable Materials & High-Performance Systems in Modular Construction

Audree Grubesic speaks with Heith Bibby, CEO of Mandeville Modular, in the Advancing Prefab series sponsored by Mandeville Modular. The post was published Feb 24 and is described as a 3 min read.

Building with performance and sustainability in mind

Mandeville Modular says sustainability is engineered into its system from the start. The company uses recycled components in assemblies, including drywall and structural elements.

The goal is to limit off-gassing materials and prioritize recycled inputs.

Education and system performance

The post says material performance depends on training. When new materials or components are introduced, teams are trained on:

Steel framing and composite envelopes

Mandeville Modular’s system uses a structural steel frame with light-gauge infill walls. The assemblies do not use organic materials within the structural envelope. Exterior sheathing uses composite concrete components.

Coastal and island conditions

The post mentions projects in Jamaica and the Bahamas. For high-corrosion climates, Mandeville Modular uses protective coatings on structural steel members to prevent saltwater penetration. The members are then encapsulated within exterior insulation and cladding systems.

Building codes and performance standards

Bibby says many building codes were developed around traditional construction methods, not advanced offsite systems. The post says modular systems are outperforming legacy code benchmarks in these areas:

Scaling modular construction

The steel structural system is presented as a path to taller buildings. The post says modular construction can compete at greater heights by using structural steel and light-gauge assemblies similar to those used in high-rise hotels. It mentions multifamily housing and large-scale commercial developments.

Ecosystem mindset

The discussion emphasizes collaboration among:

The post says education, communication, and shared innovation are necessary for high-performance modular systems to work at scale.

FAQs

Why are recycled materials important in modular construction?

Recycled components reduce environmental impact, limit off-gassing, improve fire performance, and create lighter, more efficient building assemblies.

What makes steel framing better than wood for modular systems?

Steel avoids mold, rot, and moisture damage and offers greater durability, structural strength, and lifecycle performance.

How does modular construction adapt to coastal environments?

Protective coatings, encapsulated structural members, and corrosion-resistant materials help modular buildings withstand saltwater and humidity exposure.
