    SAGE Electrochromics, Inc.
    SAGE Electrochromics manufactures SageGlass, an electronically tintable exterior glazing that blocks solar heat gain while providing glare control and preserving views. SageGlass incorporates durable thin-film ceramic coatings and uses 0.28 W/ft2 to switch the glass from clear to tinted state and 0.1 W/ft2 to maintain a darkened state. Used with typical clear glass to fabricate an insulated unit, the tinting reduces the visible transmittance (Tvis) from 60% to 1%, while reducing the solar heat gain coefficient (SHGC) from 0.41 to 0.09. The company's triple-pane (Tvis 52% vs. 3%; SHGC 0.38 vs. 0.06), argon-filled and krypton-filled glazings have center-of-glass winter U-factors as low as 0.14 (R-7.1) and 0.12 (R-8.3), respectively. SageGlass can also come with a technology called LightZone, which enables one pane of glass to be tinted to different levels in three sections. SAGE is partnering with window, skylight, and curtainwall manufacturers to produce commercial and residential products that can help save energy while improving occupant comfort and control.

    Draper’s FlexWave Light Shelf is installed on windows to reflect natural light up onto ceilings, reducing glare and the need for artificial lighting. The curved, surface of FlexWave Light Shelf reflects low-angle light far into the building. They install quickly as individual units or as part of a longer continuous run, according to the company, and no tools are needed to rotate them down for cleaning.

    SunCentral’s SunBeamer 100 tracks the sun throughout the day and uses lenses to direct sunlight into building interiors. The SunBeamer can be used in skylights or tubular skylights or in combination with the company’s SunLuminaire, SunShade, and SunSpandrel products. Using this system, sunlight is directed down the exterior of the building where reflectors in the company’s SunShade reflect and concentrate the light, focusing it into the SunSpandrel and into the building. The light then travels along the SunLuminaire, that has a reflective interior that can provide daylighting up to 50 feet into the building interior. The luminaires also contain sensors and LEDs that automatically adjust interior light levels based on available sunlight.

    Okalux light-diffusing glass uses hollow capillary fibers hermetically sealed between sheets of laminated float glass. Distributed in the U.S. by Schott North America, this unique translucent glass prevents glare and shadows yet allows light to shine through while still providing U-factors as low as 0.9 for the company’s Okalux-P glazing (expect higher U-factors for the whole glazing unit). Okalux can be customized to maximize solar heat gain, sound attenuation, and UV protection for use in façades, glass roofs, partitions, and other applications.

    The Novus 300 HRV, from Zehnder America, is a high-efficiency, Passivhaus-certified heat-recovery ventilator (HRV). Based on HVI test methods, it achieves an ASEF of 94%–96% and an SRE of 90%–91%, making it the highest performing HRV in the HVI Certified Products Database. The efficiency is thanks in part to an ECM motor. The Novus 300 can move up to 177 cfm, and comes standard with a MERV 7/8 filter, but an optional MERV 13 filter is available. An optional humidity heat exchanger is also available. The Novus 300 comes with a two-year warranty.

    Soler & Palau's MixVent inline duct fans, for small- to medium-sized installations, include four models with efficiency of 4 CFM/W or greater: the TD-100x, TD-125, TD-150, and TD-200. The TD-200 pulls more than 250 CFM, as does the TD-150 on its high-speed setting; this can cause depressurization and backdrafts in other appliances, so design accordingly. MixVent fans are mounted on support brackets from which they can be rotated outward for easy cleaning.
