About

The LubaGL system is a patented perforated solar heating technology which captures solar heat to preheat large volumes of ventilation air to the building. The collectors glazed surface allow for significant heat generation inside of the black absorber frame. The back surface of the collector uses the same perforated metal technology as the UnitAir system, to allow fresh air introduction to the system for ventilation preheating. This highly efficient system draws outside air into the system exactly where the energy is being store – amounting to much higher performance characteristics.

The LubaGL system is certified by both CSA (Canadian Standards Association) and SRCC (Solar Rating Certification Corporation) as the most efficient roof mounted 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

Components

Absorber

Much like other glazed solar collectors, the LubaGL™ system has a dark absorber surface which builds a layer of very warm air inside the plenum of the collector. The absorber or back of the LubaGL™ collector has thousands of perforations which is where fresh air is introduced into the system. This intelligent design draws the buildings ventilation air into the collector exactly where the highest concentration of heat exists. A layer of felt material is then used to help diffuse the air evenly through the plenum, while stopping radiation losses back to the outside.

 

 

Air Plenum

The collector box frame provides a 4” plenum for the heated air to travel through, which is then connected to manifold ductwork. The ductwork is connected to the outside air intake of the ventilation system. A total of eight collectors can be banked together in one row.

 

 

 

Polycarbonate

The system is covered with a UV treated double-wall polycarbonate glazing which traps the heat inside the collector, as well as insulating heat loss from the outside.

 

 

 

 

Collector Framing & Racking

The LubaGL™ system has it's own custom racking solution to support the collectors. Each module contains two rack supports, which are simply raised into the upright position on pressure treated blocking. The system rests on the roof area without any roof penetrations, and each bank of collectors are joined together using stiffener bars to create a continuous structure. Finally, the complete structure is anchored to the building at appropriate locations using airline cable and structural anchors.

 

 

Manifold Ductwork

Once each bank of collectors has been assembled into an upright position, the LubaGL system is then connected to the fresh air intake of the building HVAC system via manifold ductwork. Each bank of collectors includes a balancing key to adjust even air flow through the system.

When fresh air is drawn into the building in the winter, the outside ambient temperatures are raised up to 80F depending on 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 LubaGL solar system, as well as accelerated depreciation. Local state and utility rebates may also apply – particularly in Maine and New Hampshire currently.
