Green Designs

As demand increases for more sustainable, environmentally friendly modular workspaces, we at Enviroplex are busy sharpening the cutting edge in green design. Flexibility, utility and cost effectiveness: combining the best values in sustainable building, our engineers deliver environmentally friendly building plans that exceed expectation. How Enviroplex Advances Green Building.

How Enviroplex Advances Green Building.

Environmentally friendly modular buildings don't require a sacrifice of aesthetics, comfort or cost effectiveness. For organizations eager to capitalize on the latest advances in sustainable building technologies, Enviroplex building designers have created a comprehensive solution that advances the environmental state of the art.

All materials used in the construction of Enviroplex modular buildings, from steel and lumber to insulation and electrical components, are sourced and purchased in the United States. Made of 70-95% already-recycled materials, all Enviroplex buildings are themselves 100% recyclable.

Available sustainability features include:

  • Solotube tubular skylights with power shades
  • Automatic light adjustment with occupancy sensors
  • Low VOC, high R-value insulation
  • High performance lighting systems
  • Certified cool roof standing seam roof
  • Dual valve water saving plumbing fixtures
  • High reflectivity/low emissivity white cool roof standing seam roof (Title 24-certified)
  • SEER 15 high efficiency HVAC system
  • Vinyl-framed, dual glaze low-e windows
  • Sustainable interior finishes
  • Design features to resist mold growth

LEED Compliant.

Enviroplex designs and fabricates environmentally sustainable modular building systems that offer complete compliance with LEED (Leadership in Energy and Environmental Design) certification standards as often as possible. Established and administered by the U.S. Green Building Council (USGBC), LEED certification provides guidance for site planning, water and energy efficiency, indoor environmental quality and sustainable use of building materials.

The goal of Enviroplex’s LEED-compliant building program is to design modular building systems that use resources more safely and efficiently, protect occupant health and offer long term environmental sustainability without sacrificing utility or cost effectiveness. For more information about our commitment to LEED building certification standards, contact our offices.
