Interesting material and exchanges on Green, Inc. of late:

Green technologies have always had a challenge to make a broad impact in the market–usually because of the cost and the usual extended Return of Investment (ROI). And when you factor in the cost of REPLACING the older lighting fixtures, for example, when they are still operating just fine, thank you very much, you have another hurdle.

What is encouraging is that more and more OEM’s are including the new technologies in their new products, so that concern of “wasting” a perfectly good fixture etc. does not hold the same importance as before.

Daylight harvesting (DDH), as mentioned earlier in some posts, have been adopted. I checked the Daylight Harvesting page (if they had one) and found the company mentioned before, Axis Technologies, at two OEM websites.

Apparently, that company, Axis Technologies, actually has made some inroads with Original Equipment Manufacturers (short for lighting fixture manufacturers). A subsidiary of Philips NV, Crescent/Stoneco, uses their technology for their energy saving fluorescent lighting fixtures. Another one is Simkar, a lighting fixture company around since the early 1950’s, also uses the Daylight Harvesting ballasts of Axis Technologies.

I found the two direct links on their respective websites showing that at least some OEM’s are using Daylight Harvesting in their original manufacturing of lighting fixtures. There may be others OEM’s I am not aware of. And there may be other daylight harvesting technology used by other OEM’s, but I did not find any in my search.

Daylight harvesting is just one of many energy saving ideas, but it seems like one of the easiest to adopt. Solar energy systems are understandably very expensive and the payback period can be long, depending upon the climate.

But it is looking like that in a few more years, ground breaking technology will most likely be broadly used. LEED certified buildings are getting higher rents and have a cachet in the rental markets.

Encouraging all, just would be nice to see the pace quicken.
