ELFI Building Systems & Solutions

ELFI products, price methods, and processes & services are state-of-the art in the green-building construction market with many capabilities, benefits and advantages.  Including, but not limited to:

  • In combination, ELFI wall and roofing systems alone deliver annual energy savings of 40-60% or more, over traditional construction methods.
  • Integration capabilities with other environmentally friendly “like-minded systems”, beyond the already superbly insulated and light weight exterior envelope of a building, provide unlimited possibilities.
  • Construction time reduced by two-thirds with no ELFI-related waste: Builders establish ELFI component-centric buildings in one-third the time compared with traditional construction, yielding large cost reductions.
  • Our components are lightweight without compromising structural strength, easy to work with and easily transportable.
  • Because the two primary materials are steel and construction grade Expanded Polystyrene (EPS) foam, there is never a problem with termites, mold, mildew, warping, no ozone-depleting chemicals and ELFI is weatherized by design.
  • ELFI load-bearing components can be utilized up to nine stories and curtain wall to unlimited height.
  • Utilization of ELFI Systems, by design, provides and/or enhances the possibilities of energy-efficient, green and sustainable, carbon credits, green tax incentives, grants, stipends, rebates, EEM’s, alternative funding, etc…
  • All the materials and components are established and sustainable construction items. ELFI configuration, integration, process and methodology provide high-performance for every project, from basic design to net/near-zero to absolute zero-energy structures of any scope, every time.

When I was first introduced to ELFI Building Systems & Solutions (known then as ELFI Wall System), I had no idea that it was the beginning of such a unique & collaborative effort of energy-efficient, green &? sustainable technologies that goes beyond a usual business & personal pioneering vision. Immediately evident with ELFI (& George) were the shared-values to the extent of which I came to realize has no limit to what may be accomplished in the world of energy-efficiency. ELFI is truly a full-suite provider of best-in-class (and practice) products, engineering & consultative services, solutions and technology to address all structural initiatives within the energy-efficient building sector.

Building (Energy-Efficient) performance at its best! Two extremes immediately come to mind. The first was shortly after our Grand-Opening in December 2008 in Joliet. In January/February 2009, it was cold, very cold, -10 degrees Chicago winter cold! During the great response from the fine folks of Joliet and surrounding areas to our opening, we were busy, very busy, down the street and around the corner busy. At restaurant capacity and even with the doors constantly opening & closing, we had to run our air conditioner!

The second example is from when the entire strip mall was under construction, under the intense summer heat (of greater than 100 degrees & humid), under cover of only the, still open/unfinished, ELFI Wall & Roofing (panel) System. My wife (reluctantly, due to the heat and going to a construction site) and I visited the future site of the greatest Denny’s in existence (Green & Sustainable Denny’s) and we were astonished that within the “open” ELFI structure only, we found ourselves standing in a pleasant & comfortable seventy-something degree temperature. I knew at that moment that we were on to something great with the possibilities of ELFI building technologies!

Insulate tight, ventilate right. That’s an ELFI structure. That’s empirical proof that I PERSONALLY have seen and experienced; it’s undeniable, energy-efficient and true… AND IT’S GREEN & SUSTAINABLE TOO!!! -Joey Terrell
