It was demonstrated in the 1980’s by government funded projects across the U.S. that building energy consumption reductions of 50% to 80% can readily be achieved through design at little or no additional cost. Since then countless buildings have been designed and built both in the U.S. and abroad that confirm this.
| ![]() Energy Consumption of the Mount Airy Library Compared to Similar Buildings in the Area“The daylighting design is a great success economically and visually. A typical commercial building uses about 20,000 Btu/sf annually for lighting. Mt. Airy used only 2,691, a reduction of over 86 percent”. “The bottom line is that the daylighted Mt. Airy Public Library is a low-energy use building that’s extremely attractive, aesthetically pleasing and that the people of Mt. Airy have declared, by their enthusiastic utilization of it, a runaway best seller.” Sarah Shankman |
