| Energy Retrofits: When Is the Time to Act? By LANCE ENGLISH; VICTOR SANVIDO, PhD; and DON HARRISBERGER, PE, LEED AP; Southland Industries; Irvine, Calif. |
| Many building owners think of solar fields, cogeneration, solar hot water, and absorption chillers when they hear the words "energy savings." Although these high-profile, trendy options can reduce energy costs, they typically require substantial investments that must be financed over several years to achieve a reasonable return. Savings projections usually assume that existing mechanical systems, in conjunction with the previously mentioned technologies, are operating efficiently. History tells us that is not always the case. [MORE] |

| ASHRAE Online Courses Feature High-Performance Guidance |
| Two courses related to high-performance building design are being offered as part of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Learning Institute’s spring online series. Twelve online instructor-led short courses will run from late March through early May and are available to those interested in expanding their knowledge of the HVAC industry and keeping up to date with the latest technology. Many courses include updated material. [MORE] |
| LEED Volume Program Certifies 500th Pilot Project |
| More than 500 building projects have been certified through the LEED Volume Program since the pilot launched in 2006, according to the U.S. Green Building Council (USGBC). The program streamlines the certification process for high-volume property owners and managers, from commercial real-estate firms, national retailers, and hospitality providers to local, state, and federal governments.

| Heat-transfer fluid |
| Specially formulated for geothermal heat-pump systems, DOWFROST GEO 20 is a ready-to-use inhibited-propylene-glycol-based heat-transfer fluid. Biodegradable, the fluid has a low order of toxicity and is formulated with 20-percent propylene glycol by volume to provide high heat-transfer efficiency. The fluid also contains corrosion inhibitors that satisfy the requirements of ASTM D1384, Standard Test Method for Corrosion Test for Engine Coolants in Glassware, protecting equipment from damage or failure when used at full strength.

| Fabric-duct systems |
Featuring an in-duct cylindrical tensioning device that eliminates sagging and wrinkling, SkeleCore fabric-duct systems maintain an inflated appearance, even during idle air-handler periods. Because of the tensioning device, the popping sound often associated with equipment startup is eliminated. The systems consist of a ¾-in.-diameter, lightweight aluminum tube supporting a series of 3/16-in.-diameter powder-coated-steel connecting rings sized to administer tension on inner fabric-duct walls for a permanently inflated appearance. The backbone tubes are 6 ft long and designed to snap into the support rings and couplers with a spring-loaded, quick-connect/release mechanism. The systems are available in 15 diameters ranging from 8 to 36 in. [MORE]—DuctSox

| Condensing boilers |
Available in five models ranging from 1.5 to 3.5 million Btuh, CREST condensing boilers offer firetube technology integrated with SMART TOUCH operating controls. With thermal efficiencies of up to 99 percent, the fully modulating boilers feature a low-nitrogen-oxide combustion system with a stainless-steel heat exchanger and a dual-system burner design with a turndown ratio of up to 25-to-1. The top-mounted, single micro-metal-fiber burners serve as two combustion systems in one, each with its own blower and gas-valve assembly to power the combustion process based on demand.

| Hydrogen/refrigerant tester |
Designed to use a safe, non-toxic tracer-gas mix of 5-percent hydrogen and 95-percent nitrogen (or any gas mixture with hydrogen), the Trace300 benchtop hydrogen/refrigerant leak detector determines leak tightness. It also can be used with applications in which 100-percent hydrogen is present. The tool can detect refrigerants such as R-22, R-134a, and R-410a. [MORE]—NuvoTrace

| Duct-temperature sensors |
Featuring a Qwik Connect system that eliminates wire nuts, Qwik Series duct-temperature sensors come in three styles. The Qwik Box features a galvanized enclosure and is available in IP40- and IP54-rated models. IP54-rated, the Qwik Mini features a plastic enclosure. The Qwik Flange is available with a variable-air-volume option. All of the sensors come in a variety of negative-temperature-coefficient-thermistor or resistance-temperature-detector elements and have probe lengths from 4 to 18 in. The sensors also feature a small outdoor sensor, strap-on pipe sensor, and immersion sensor. [MORE]—Tasseron Sensors and Controls Inc.
