3 ~ Ib a 1 "This light pollution t think a {ot of people can attest in the last five to ten years has been ~ ~ ~ 2 appreciable. And was even recognized last week on a foggy night I was driving back from 3 Carrboro in the distanceaham'g It was a smallocalyddealerslhip out inlWhite Cross areanthat 4 Burlington, it can't be G 5 looked like it was some sort of major sale going on there. 6 7 "So even some small projects can really have quite an impact upon the rural 8 environment that is out there. Besides these businesses and residences, this light pollution can 9 affect the enjoyment of the night, the dark sky, enjoyment of the neighbors. You will also notice 10 that driving conditions based on inappropriate lighting can also cause hazards while driving. 11 Energy conservation, we just didn't want to limit it to light pollution we understand that in our age 12 of energy star housing where we are reducing the amount of energy necessary for housing, 13 there is also a way of reducing the amount of energy for lighting and you have noticed the 14 different color-coded lighting out there, there is yellow lights, there is the blue lights, there is the 15 white lights, there is the reddish lights. 16 17 "There are certain types of these lighting that are high-energy consumption. And what 18 we are suggesting, at least at the public hearirig stage, is the prohibition of mercury vapor 19 lighting which is as we have analyzed high energy consumption. And there is a chart which will 20 go next that just gives an exa oPl~e who ma the li l afterwardsres that are out there and some of 21 the costs that accrue to the p p P Y 22 23 ~ "Now we also understand that the costs of the initial installation is part of the capital 24 improvement and costs of providing these facilities, but also if you take a look at the cost of that 25 electric service afterwards by reducing this long term electric consumption, the need and 26 dependency on sources of electricity could be brought down. 27 28 "Also another initiative that we are taking a look at is where possible, where feasible, 29 where applicable, we are encouraging the use of solar lighting ,and solar lighting technology 30 just over the last five years has moved forward in leaps and bounds and we are interested in 31 proceeding with some sort of solar lighting application at our building in Orange County here 32 that was knocked down in a storm a few years and we are still without sign and without lighting 33 and so we hope to use and attempf some new technology for solar lighting for that sign out 34 there. This is just a quick chart of energy conservation -low pressure sodium, 35 watts, 35 annual operating costs about $19.00, high pressure sodium -75 watt fixtures, about $30.00, 36 middle halide?? - 100watt bulbs, $37.00 approximately, and mercury vapor -175 watts, 37 $67.00. 38 39 "So you can see almost 3 and'/2 times the cost of providing lighting with different types 40 of fixtures and applications. Now there is a combination- it doesn't mean that you have to 41 provide 3 and '/z times as many lighting fixtures as low pressure sodium to make the project 42 work. This is just an example of how we have done in energy conservation analysis to make 43 sure that future lights take that into consideration. The consequences we hope that the benefits 44 abound, better driving conditions still allowing for appropriate security for people that want to 45 preserve their properly, using conservation measures to reduce our dependency on electricity , 46 using these solar opportunities, supporting the dark skies initiative so people can enjoy the 47 stars out there. And also taking a look at lighting so that it is used for its intended purposes of 48 security and invisibility and using the crime prevention through environmental design 49 techniques. So those are some of the positive consequences, we did not elucidate any other 50 issues that have negative consequences. . 51
