Solar Lighting

  1. Area of Sustainability: Energy

    For most commercial buildings, lighting constitutes as the highest electricity user compared to other single uses. Additionally, many office buildings do not take advantage of daylighting, either because it is infeasible in some buildings or they don’t have the right design tools. Only employees sitting by the window receive natural sunlight. Studies show that daylight improves an occupant’s health and well being as well as productivity. An average person in the US spends over 90% indoors, without natural light.
  2. Technology Solution: Solar Lighting
  • Parans has developed a daylight system that uses fiber-optic cables that deliver natural light captured by solar roof collectors (pictured above). The sunlight collectors are designed track the sun’s movement and therefore capture maximum sunlight. The free and renewable resource that is sunlight, would therefore also lower a building’s total energy usage from lighting.
  • This technology can provide natural light to the interior of the building as well as the basement – the two areas that typically lack access natural light. This light can be distributed as Point Light, Ceiling Light and/or Wall Light.
  • Originally a Swedish company, the technology is being integrated in many parts of the world. Lumenomics has partnered with Parans and is now the US distributor of their daylight systems.
  • This system is being used in healthcare facilities like NICU at Denver’s Presbyterian St. Lukes Medical Center, at University of Arizona’s Innovative Health Sciences Building, and even in Rijnands Tunnel in Netherlands, where lighting is crucial to avoid accidents.

3. Organizational Stakeholders:

  • Owners of buildings
  • Facilities Management Team
  • Occupants of the building
  • If its not a building, but an infrastructure project like the Rijnands Tunnel, then the local government and all contractors involved

4. First 3 steps in deploying this technology in a new building (since this technology already exists):

  • Setting up an initial meeting/call with Parans to gather more information
  • Assessment of the building
  • Installation of the lighting system according to preferred lighting spread (point, ceiling and/or wall)
