Why ELFI

for all structural parameters, and Master Planning for large development projects, ELFI Building Systems & Solutions is a Chicago-based manufacturing, engineering and consultative integrator of energy-efficient, environmentally friendly, climate-responsive, pre-fabricated and pre-engineered, wall and roofing systems that integrate and optimize every building initiative. Our systems combine structural, load-bearing steel framing and Expanded Polystyrene (EPS) foam insulation into one product.  With energy-efficiency foremost, ELFI’s integrative component-based, system of products, methods and processes are state-of-the-art in the green-building construction market, and ELFI Systems are integratable with all efficiency-focused advanced technologies, products and systems.

builders can construct ELFI component-centric buildings in one-third the time when compared with traditional construction methods.  This results in significant on-site, time and cost savings (rapid-build technology equals faster ROI). Lightweight and easy to work with, our two main components, steel and EPS (combined), yield major benefits:  Structural integrity, no termites, mold, mildew, or warping – and, there are no ozone-depleting chemicals – and, our systems facilitate superior Indoor Air Quality (IAQ). The ELFI exterior building envelope alone delivers annual energy savings of 40-60% over traditional construction materials and methods, and by implementing our advanced methods of integrating other features and products, this will culminate in even greater savings. ELFI’s exterior envelope, with its unmatched energy-efficiency ratings, has been successfully deployed for more than 15 years in retail stores, single and multi-family residences, commercial, governmental, and specialty construction.
