IST News

This November IST began the installation of flat plate domestic hot water systems on five row homes on Madison Street built by the Northeast Denver Housing Authority. These houses for low-income residences were constructed with energy conservation in mind. The addition of solar hot water heaters will provide additional relief for residents from escalating fuel bills.

Also in November, IST began work on the Garden Crossing section of the Holiday Neighborhood housing project in north Boulder. Developed by Peak Properties and designed by Downing Thorpe James, Architects, IST will pre-plumb all 55 units in the development for solar domestic hot water heating. Insulated piping and a control wire will be installed from the basement to the roof during the construction period. New owners have the option of having a complete system installed prior to move in, or having the system installed later at their convenience.

Industrial Solar Technology featured prominently in the Solar Tour of homes this October in the Boulder and Denver Metro areas. On display were recent IST installations at the Ching residence, Nederland (pool, hot water and DHW heating); the Depoyster residence, Idaho Springs (off grid photovoltaic system with solar space heating and hot water); the Levi residence, Boulder, (space and DHW heating); and, the Getliffe residence, Boulder (DHW heating). 

Though not a residence, the North Boulder Recreation Center was also on the tour. We received many visitors wishing to inspect the solar system behind the scenes and eager to learn about the other "green" features of the Center. Many thanks to Bill Boyes, Director of Facilities, City of Boulder for showing tour participants around the recreation center including adventure tours to the roof to view the large expanse of solar collectors.

In June 2003, IST started up its largest roof mounted trough system (RMT) to date at Fort Sam Houston in San Antonio. (See "About Troughs" and "Roof Trough Specs.") This system is mountedon the roof of an energy showcase building that also features a 50 kW PV system. At peak conditions, the solar RMT system delivers about 200 kW of thermal energy to a district heating loop for building DHW, space and air-conditioning reheat. IST manufactured and installed the RMT system under contract to Johnson Controls, Inc.

In 2002, also working for Johnson Controls, IST designed six separate flat plate solar systems that were installed at the Audie Murphy Veterans' Memorial Hospital, San Antonio and at the Veterans' Administration Hospital, Kerrville, Texas. These solar systems involve applications for DHW heating, hot water for a laundry, boiler feedwater heating, space heating and air-conditioning reheat. Besides designing the systems and providing installation and startup services, IST supplied flat plate solar collectors, mounting hardware, controllers and solar hot water storage tanks ranging in size from 1200 to 5400 gallons.
