Thanks to Scenic Railroad for memorable day with grandson

To The Daily Sun,

Please allow me to use your paper to thank some very special people. On June 29, our granddaughter, Ella, took a great ride on the Hobo Scenic Railroad that goes along Paugus Bay. The trip could not have been nicer due to awesome, caring people in the train's crew. We want to particularly thank Engineer Tony, Conductor James, Dave and Theresa and the outstanding balloon artist. Ella enjoyed a wonderful trip along the big lake due totally to the efforts of this fine crew. The balloon artist made Ella an orange cat, just like her cat, Otis, while others did special favors for her along the way. Your hospitality made for a very enjoyable day for Ella and Grandpa.

Engineers & architects need to get with the 'green' program

To The Daily Sun,

Energy is all around us. Most of it is not carbon based. So why don't we prepare to use it with the aid of existing technology? The sun can be harnessed. At some locations it is already being done. In Seattle there is a building that employs a design of which I speak. It's called the Bullitt Center. It is described as the greenest commercial building in the world.

The building is 52,000-square-feet in size and houses several tenants. It was constructed in 2012 and features a 242 kilowatt solar photo voltaic (PV) array. In addition to providing the structures energy needs, it produces 60 percent more electricity than it uses. A common green building measurement used to describe the amount of energy a building uses annually relative to its square footage has evaluated this building. The test, Energy Use Intensity (EUI), has produced a score of 9.4 for the Bullitt Center. That translates to almost a 90 percent reduction when compared to the average building of similar size in
Seattle.

The (PV) array features 575 Sun Power panels in a 14,000-square-foot roof. The building also uses a geothermal boost for a hydronic heating and cooling system. A number of automatic systems monitor and operate within the building to enhance the maximum efficiency. For a more in-depth analysis of the building features, go to www.BullittCenter.org.

If such a building works so well in Seattle, think of how much better it would for a city like Phoenix. Engineers and architects need to get with the program when new building designs are readied for construction. They need to know what materials are available, what is the most efficient use of those materials and how to make sure builders follow design specifications. Also necessary is a new vocabulary of terms use in this cutting edge technological marvel.
Some of those essential terms are inverter, ground-source heat pump and (DNI) direct normal irradiance. For a more complete list of terms you could go to the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy web site or I will loan you a copy of “Green is Good.” It was written by Brian F. Keane and documents some of his experiences in Connecticut.

If the current administration is serious about allocating some serious money on infrastructure and power grid modifications, they should send Mr. Rick Perry, Secretary of Energy to a few cities like Seattle and Tucson. Tucson has a massive photo voltaic array capable of producing up to 5 megawatts of power. That is estimated to be enough to meet the power needs of a thousand homes. It's located under one of the approaches to the airport. Because of the noise under the glide path the array has found a perfect home.

In closing, I find it hard to believe that, given just these two examples, there is so much passion generated in reference to getting coal and oil a bigger share of the power generation marketplace.
