Heliostats serve many industries as a general-purpose, low-cost heat and light source. One of the simplest uses of heliostats is to provide heat and light for buildings – saving money, and often generating valuable LEED points for your green building project.

Heliostats work by reflecing sunlight onto a target with a computer-controlled mirror. Small adjustments to the mirror’s position keeps the reflection steady even as the sun moves across the sky.

Unlike Photovoltaic panels – which convert only a tiny percentage of sunlight into electricity – heliostats reflect 85%-90% of the sunlight onto their target. This means relatively few heliostats can have a large impact on a building’s energy use.

Buildings Magazine mentions LightManufacturing heliostats in their Green Facilities Issue

Each LightManufacturing H1 heliostat delivers 1300 peak watts of heat, and 115,000 lumens of light to a building – and this energy enters through existing windows and apertures. No expensive heating system modifications are required, and retrofits are simple. From single family homes to multistory office towers, most buildings can benefit from heliostats.

Compared to competing solar technologies and other energy conservation methods heliostats offer:

  • low purchase cost
  • simple installation
  • easy retrofit to existing structures
  • ideal for infill development and new construction
  • minimal impact on building systems (no need for changes to HVAC)
  • direct, quantifiable reduction of fossil fuel heating costs
  • direct, quantifiable reduction in electricity use / lighting costs
  • improved light quality and intensity
