Hines is a global real estate company located in Silicon Valley.Power Efficiency Guide  The company implemented energy efficient lighting retrofits in over 200,000 square feet of its facilities, reducing its annual lighting expense by up to 70 percent and improving its lighting levels by 10 to 50 percent. The company realized a first year ROI of 31 percent on the project.Washington D.C. Office Building Annual Savings $132,750 A 12story Washington D.C. office building managed by the Stillman Group underwent an energy efficiency lighting retrofit and reduced its annual lighting expense by up to 70 percent. As an added benefit, the building also improved its lighting levels by 1050 percent. The building's management group realized a first year ROI of 80 percent on the project.

If you are wondering why you should install solar screens you might want to consider the history of how solar screens came about. The idea of a solar screen probably originated in the caveman days. When the sun became to unbearable the ancient caveman likely retreated into his shaded cave to escape the harsh effects of the sun's rays. That's so easy a caveman could do it!As history progressed and man began to build homes of logs and rocks, he designed windows into the house for ventilation and lighting, and outdoor views. Of course, those windows which were exposed to the direct sun created a lot of heat in those old homes and he designed shutters to close over the exterior of the window to mitigate the harsh sun ray's effects. When he did this, he destroyed the 3 unique benefits the windows were designed for, ventilation, light, and outward view.

History progressed and man invented cooling. Now he could put cooling in his home and open up the shutters. If the sun heated up the home too much he just turned down the thermostat to make it cooler. This felt good on the sunny side of the house but the other side of the house got too cold. So man discovered the use of curtains, shades, and blinds to filter the sun. Unfortunately, all these devices did was slow down the heat but it eventually came into the room and had to be removed by the "air conditioner".

As man became more industrialized he used more and more energy and the demand caused the cost of electricity to go higher and higher. A solution had to be found so that people could continue to have windows in their homes and buildings for lighting and outward views, not to mention some fresh air now and then! This is where the idea of a solar screen was invented. Windows had bug screens so the flying insects would not come into the house or building when the windows were opened for ventilation. Why not develop a thicker and heavier mesh to block the sun's rays from coming through the window This would still allow air to enter the open window, would let some of the sunlight in to supplement the interior lights. This was very important since it requires electricity to operate the lights, and people inside the buildings would still have an outward view!
