Even simple on-the-job green initiatives carry significant environmental impact. Here are several easily implemented ones:

- Where possible print all documents double-sided
- Use recycled paper as much as possible
- Utilize paperless communications and save emails on line instead of copying them
- Encourage telecommuting by employees when feasible
- Provide indoor bicycle racks
- Have employees use non-paper cups, mugs, and dishes when at work vs. disposables
- Encourage the use of water fountains or coolers vs. single serve bottles


Starting with this article, we will be featuring "Green Tips". These are actions any business or person can adopt which will have a positive environmental impact - and keep us Eco-conscious.


- Use Cruise Control - maintaining a constant speed saves gas.
- Consider Speed Limits - speeding (as we all do) uses up more gas. Most vehicles maximize
fuel efficiency at 50 mph.
- Maintain Your Vehicle - change air filters and spark plugs on a scheduled basis.
- Remove roof racks when not using.
- Maintain proper tire pressure - low pressure costs lots in wasted fuel.
- Reduce Vehicle's Weight - remove heavy objects from trunk and rear seats, i.e. sand bags
used during the winter months.
- Consolidate Your Driving - organize your to-do list and plan ahead to minimize time and

Make no mistake, every cinema must have a video projector for pre-feature presentations, for rentals and parties, for film festivals and gaming, but you must insure (and I can't stress this strongly enough) the projector that you purchase produces on-screen image that is equal to a high definition TV image. That means purchasing a projector with enough lumens (at minimum 75 - 100 lumens per foot of image throw) and the appropriate lens necessary for the image to fill the screen.

EEC sells Christie, Sony, and Panasonic video projectors each having a large selection of projectors suitable for cinema operation. Don't make the mistake of buying a small, inexpensive consumer model from one of the big box retail stores - it won't and can't do the job.


In the article above (published in Cinema Training Central Flash #5/08) it was brought to my attention from several readers that my recommendation on lumen calculation in determining what size video projectors would be best suited for a particular auditorium and screen size was not as accurate as other calculations. This is true. I recommend the use of a simple lumen calculation based on length of image throw. Simply, throw times 75. For example: a 50 ft. throw x 75 = 3750 lumens.

A more precise calculation, as was pointed out to me, would be image height times width x 14FL (FL = foot lamberts of reflected light). For example: a 12 ft. high x 22 ft. wide image would calculate to 264 sq. ft. x 14 = 3696 lumens required. The simple throw calculation will always be higher (which in and of itself is OK) but not as precise. Where the problem may arise is when you have a situation where there is a large image and a short image throw. Then it's best to use the more precise sq. footage calculation.
