BioheatUSA, formerly Tarm USA, supplies high-efficiency wood and pellet boilers. The three wood-gasification boilers are designed to run at high-fire only—so as to achieve high combustion efficiency with highly variable wood fuel. For efficient wood heating during fall and spring, BioheatUSA supplies add-on hot-water storage systems. The HS Tarm Solo Innova provides efficiencies in the mid-80% range, while the baseline Solo Plus model achieves efficiencies up to 80%. The wood boiler fans draw 75W–100W. These boilers require their own chimney flue. In typical installations the existing fossil-fuel boiler is retained as back up, and the wood boiler vents into a second existing flue. BioHeatUSA is the exclusive importer and distributor of Froling and Tarm products with dealers throughout the United States and Canada.

General Panel Corporation produces an EPS-core SIP system. The company offers panels with a EPS core thicknesses of 3-5/8", 5-5/8", 7-3/8", 9-3/8", and 11-3/8" with corresponding R-values of 15, 23, 30, 38, and 46. The company produces panels in Mississippi and Tennessee.

Daikin’s Altherma is an air-source heat pump system that can provide heating, cooling, and domestic hot water. Altherma is available with split-type or outdoor-only heat pumps along with a “Hydrobox” heat exchanger that transfers heat to a hot water storage tank. These tanks come in 50- and 80-gallon options and have back-up electric heating elements. Altherma is available for heating only or for heating and cooling (where the refrigeration cycle is reversed). Altherma can be plumbed into a radiant flooring system or a hydronic fan coil unit for forced air applications and is available with a solar thermal option. Altherma uses R410a refrigerant and some units have COPs as high as 4.34 and EERs greater than 12.

The Securus ACDC12 is a solar hybrid heat-pump air conditioner and heater suitable for spaces up to 750 ft2, or to supplement a larger system. It may be connected to up to three PV panels (for a maximum total of 700W) for its primary daytime power, and then runs on standard 220VAC grid power overnight. The SEER 20 unit provides 11,000 BTU of cooling; in the winter it provides 12,000 BTU of heat in temperatures as low as 5°F.

Perlite is an amorphous volcanic rock that is expanded at very high temperatures to create a lightweight insulating material typically used for loose-fill applications. GAF adds up to 50% cellulose fibers and up to 30% asphalt to bind the perlite together in its EnergyGuard boardstock insulation for roofing applications. With inherent fire resistance and insulating value of R-2.78 per inch, EnergyGuard provides an alternative to polystyrene and polyiso boards. It is installed directly on top of a structural roof deck. GAF designed the product for use under built-up roofing or modified bitumen, so some single-ply roofing membranes may not be compatible with it. GAF offers the boards in standard 2'x2' and 4'x4' sizes and 3/4", 1-1/2", and 2" thicknesses.

Foil-Grip 1402 is a zero-VOC aluminum tape with butyl sealant for use on flexible ducts. According to the manufacturer, Foil-Grip will adhere at temperatures up to 180ºF, is rugged enough for outdoor or below-grade use, and has a 40-year service life. Foil-Grip is available in 100' rolls in widths from 2"–36".

FlexFix is a zero-VOC, oriented-polypropylene tape with acrylic sealant for use on flexible ducts. FlexFix is hand-tearable and the manufacturer claims it will adhere in temperatures from 0ºF–210ºF. FlexFix is available in 3" and 48mm widths in black and silver.

Intertape AC 698 is a zero-VOC, oriented-polypropylene tape with acrylic sealant for use on flexible ducts. AC 698 hand-tears and Intertape claims it will adhere in temperatures up to 210ºF. AC 698 is available in black, clear, silver, and red.

GreenFiber offers seven varieties of cellulose insulation, all of them containing 85% recycled paper fiber (55% post-consumer and 30% pre-consumer). The various products are designed for specific applications, including spray, blow-in, and loose-fill insulation for attics, new-construction walls, and wall retrofits. Four are low-dust formulas and three are treated only with borate.

Greenheck offers the VCD-23 and ICD-45 low-leakage control dampers. The galvanized steel CDD-23 is engineered for use in low- to medium-velocity HVAC systems; the ICD (insulated control damper) comes with a thermally broken frame that incorporates polystyrene insulation, blades insulated with polyurethane foam, and thermal breaks made from polyurethane resin. Both of these dampers are available in a wide variety of sizes.

Somfy Systems manufactures a number of different systems to motorize window coverings and help regulate solar exposure. Their products can be applied to retractable awnings, rolling shutters, exterior screens, and interior shades. The systems are programmable and remote controllable, and can also be controlled via an Internet-based interface. Research suggests that motorized and automated window coverings significantly improve the energy performance of adjustable window coverings, in both homes and commercial buildings.

Multistack MagLev flooded chillers provide cooling for offices, schools, and other large commercial buildings using compressors with shafts supported by magnetic levitation. By minimizing friction, the system improves energy efficiency and eliminates the need for mechanical seals, gears, and many other conventional components. The systems also reduce maintenance and the use of lubricating oil that tends to to contaminate the refrigerant and further reduce efficiency. Available in capacities from 70 to 1,200 tons, these units use the company’s FlexSys controllers, which can control a series of magnetic levitation compressors to create the most efficient cooling.

Crosley offers three washers—two front-load and one top-load—meeting GreenSpec criteria. The washers, with capacities of 3.3–3.9 cubic feet, have MEF ratings of 2.48–3.09, WF ratings of 3.3–3.64, and estimated annual electricity use of 83–123 kWh.

Constant airflow regulators (CAR) from American Aldes help balance ventilation in HVAC systems, minimizing the “stack effect” and other airflow problems and reducing the need for ventilation fans and the amount of energy used by heating and cooling systems. The CAR technology can be used to provide ventilation to occupied areas only and is incorporated into a number of American Aldes products used for ducts, exhaust registers, supply registers, grills, and more.

Soraa Vivid MR-16 LED luminaires are ideal for use where light quality is critical, such as art galleries or retail displays. Unlike other LEDs that use gallium nitride (GaN) crystals grown on a sapphire or silicon carbide base, Soraa uses GaN grown on a GaN base so the crystals have far fewer imperfections. Though less efficacious than some LEDs, Soraa MR-16s produce higher intensity, “full spectrum” light that rivals halogen bulbs, while operating at lower temperatures. They are available in 14-, 25-, and 36-degree beam angles.
