Lubi Glazed Solar Siding

REPLACES commercial siding solutions with FREE solar energy - The most efficient solar air heating system ever tested!

Lubi Glazed Solar Air Heater

The Lubi wall system is a solar heating system that provides clean, renewable heat for commercial, industrial, agricultural, municipal and institutional buildings throughout the world. As an architectural siding solution, the Lubi system is the first economical solar solution that literally replaces conventional siding solutions without adding to construction budgets. That means your new building can have FREE solar energy without any capital investment - Contact Us to learn more...



The Lubi system by Enerconcept Technologies, Inc is a patented perforated glazing technology which captures solar heat to preheat large volumes of ventilation air to buildings. Released in 2010 by Enerconcept, the Lubi system was awarded the “Most Innovative Product” at AHR 2012 (American Heating Refrigeration), and has been installed on municipal, industrial, agricultural, commercial and military facilities across the world. The Lubi system is certified by both CSA (Canadian Standards Association) and SRCC (Solar Rating Certification Corporation) as the most efficient solar air heating system in the world.

It is also the first time that solar heating has been offered as an architectural design solution to buildings giving designers and engineers the freedom to challenge the boundaries of both form and function.

How it Works

 Lubi™ Solar - How it Works




The system takes any existing wall surface and turns it into a solar absorber. This absorber can be a black metal collector supplied by Enerconcept, or can be existing brick, metal or any other existing wall cladding system. Logically, the darker the material - the higher the performance.




Air Plenum: 

A series of framing members are installed to create a wall cavity where air can travel within the system. These framing members are a combination of galvanized and powder-coated perimeter framing, and extruded aluminum vertical bars. The plenum is sized to allow control of air, and is normally between 4” to 8” in depth, depending on air flow.




The systems clever design incorporates UV treated polycarbonate glazing panels which completely cover the framing system to create an enclosed air plenum/space. The sun heats through the surface of the glazing where the absorber retains this heat, creating a layer of very warm air. Unlike other glazed solar heating systems, the Lubi system has a unique patented perforation technology which allows air to pass through the surface of the collector via tiny holes in the polycarbonate surface.




Trim & Flashing: 

Once the panels are installed, the system is finished with an innovative aluminum trim system which has very similar properties to curtain wall/window wall glazing.




Air Intake: 

The Lubi wall system is connected to the fresh air intake of the building HVAC system to then behave like a supersized “solar intake louver”. When fresh air is drawn into the building in the winter, the outside ambient temperatures are raised up to 80F depending on air flow and sunlight, to drastically reduce the volume of energy required for ventilation heating.





Ideal Applications

The Lubi system is ideal for any new commercial construction project, and is extremely well suited to existing facilities such as:

  • Athletics & Health/Fitness Centers
  • Indoor Pools
  • Healthcare/Hospitals
  • Wastewater Treatment
  • Veterinary & Animal Services
  • Schools & Universities
  • Auditoriums/Stadiums
  • Agriculture
  • Auto Body, Metal Fabrication/Welding & Paint Spray Booths
  • Laboratories, Clean Rooms
  • Food Processing Plants
  • Industrial Manufacturing
  • Industrial Boiler Room Make-Up Air
  • Warehousing & Distribution Centers

Tax Credits & Rebates

The Federal Investment Tax Credit (30%) currently applies to the Lubi solar system, as well as accelerated depreciation. Local state and utility rebates may also apply – particularly in Maine and New Hampshire currently.
