U.S. DOE releases new fact sheet on light + health

Check out the new fact sheet published by the DOE.  It helps to clarify and dispel some of the myths surrounding LED lighting and its impacts on health. I think this paragraph is the perfect summary: What may be beneficial for an occupant during the day may be harmful at night, and may vary significantly between indi­viduals in a given space. Complicating things even more is the need to balance the desire for alertness with preservation of normal circadian rhythms among night-shift workers, for exam­ple. Therefore, even if a prescription for effective nonvisual stimulation is developed, implementing the solution may … Continue reading U.S. DOE releases new fact sheet on light + health

U.S. DOE SSL releases 4 SBIR grants

As part of my ongoing effort to track innovative small companies in the lighting world (see this post and this post for some more ventures), here is a release from the U.S. DOE on their latest Small Business Innovation Research grants: Four SBIR Grants Awarded for SSL Technology (FY14 Release 2 Phase I) The U.S. Department of Energy Office of Science has awarded four Small Business Innovation Research (SBIR) grants targeting advances in solid-state lighting (SSL) technology. The FY14 Release 2 Phase I awards will explore the technical merit or feasibility of an innovative concept or technology. The SBIR and … Continue reading U.S. DOE SSL releases 4 SBIR grants

project haystack

Perhaps some digital “glue” to hold the building automation world together?  Check out Project Haystack. Most of this site is for software programmers (and beyond me) but it fits nicely with my concept that the next evolution of lighting will be enabled by smart new industry standards that will drive innovation by connecting dynamic lighting systems with architects and contractors (via BIM), and the lighting specification community (via enhanced lighting system simulations). Project Haystack is an open source initiative to develop tagging conventions and taxonomies for building equipment and operational data. We define standardized data models for sites, equipment, and points related … Continue reading project haystack

how to build a circular economy

Nice article in Fast Company introducing the principles of Circular Economy strategies, mostly taken from the Ellen MacArthur Foundation. A circular economy is one where goods are restored and regenerated more widely, moving from a system of virgin inputs and piles of waste to one that returns used products to a useful state. It is also an economy that minimizes resource use by moving away from individual ownership towards more leasing, renting, and sharing. The aim is to cut environmental damage and allow companies to keep control of the value in their products. Continue reading how to build a circular economy
