By Nancy Crotti The 10 ton XX packaged heat pump and three- to five-ton ZQ 14 SEER air-conditioning units feature an exact-fit replacement designed to match the footprints of other manufacturers’ units and reduce installation time, cost and complexity by eliminating the need for a curb adapter. The units can be controlled via a smartphone, tablet, laptop or remote PC. An optional fault detection and diagnostics system provides detailed alerts if issues arise. The Direct Replacement mobile app for Apple and Android devices can help in the selection process.

By Nancy Crotti These in-wall and ceiling-mount sensors use passive infrared and ultrasonic technologies to monitor virtually any area within a building. They work with any lighting type, including LED, and can be installed in retrofit and new construction. They have a 5 A electronic ballast rating, meet the NEMA 410 standard and are Title 20 compliant. They can manage lighting in partitioned bathrooms, open areas with cubicles, storage rooms and libraries. Adjustable features include PIR sensitivity, time delay (15 seconds to 30 minutes) and ambient light sensor override.

By Nancy Crotti Johnson Controls has upgraded its building automation system with graphics available across multiple mobile devices, alarm management that enables alarm prioritization for improved productivity, and better scheduling and custom trending to save time and ease troubleshooting. New reporting features make it easier to access trends, alarms, audits and data for scheduling. Spaces authorization allows tenants to access the system and see only the data they need. The system has secure password management, as well as dormant user account reporting.

By Nancy Crotti This new “cool roof” system’s white surface is designed to reduce the impact of infrared rays on building cooling requirements. The low-VOC resin membrane system is fire rated for Class A assemblies and exceeds the requirements for LEED credits. No reflective topcoat is necessary.

By Nancy Crotti SolarWindow’s transparent electricity-generating coatings can be used with glass-to-glass laminated products such as skyscraper windows, according to recent performance tests. The tests used laminated SolarWindow modules and demonstrated that the system maintained its color and clarity, and that its module seal and electricity interconnection system remained intact.

By Nancy Crotti Terralux has come out with a self-contained LED retrofit kit for 8  inch to 12 inch commercial downlights. The DVRH Retrofit Kit is designed to replace as much as 175-watt lamps and use high-intensity discharge bulbs of as much as 175 watts. The company is touting it as a solution for high ceilings, atriums and canopies that can be found in airports, convention centers, shopping malls and office buildings. The kit reuses the original downlight fixture, less the old ballast and bulb. All models are Energy Star certified as Luminaire Retrofit Kits, which qualifies them for utility…

By Nancy Crotti This system offers per-watt efficiency of as much as 177 lumens per watt while delivering between 33,000 and 68,000 Lumens. It allows customers to retrofit 750-watt to more than 1,000-watt HID lighting systems as well as 10 to 14 Lamp T5 fluorescent lighting systems while reducing energy consumption by as much as 70 percent. The modular system features wireless networking and remote-control sensors, thermal management design that reduces fixture operating temperature to enhance performance, and LED chips and drivers paired with cooler operating luminaires.

By Nancy Crotti These photovoltaic solar panels are affixed to a lightweight, adjustable aluminum frame, a setup that can be customized for roof size and structure as well as the particular solar capacities of the site. Designed with New York City residential rooftops in mind, the system can accommodate adjacent structures, foliage, roof penetrations, roof access and maximum wind and snow loads, and can expand a rooftop solar system by as much as 200 percent.

By Nancy Crotti A tool-less, hinged door allows for safe access to the six-volt NiMH battery, and 3.6-watt, adjustable LED lamp heads enable maximum on-center spacing to as far as 60 feet. A 58-degree-wide beam lens works well with lower mounting heights or shorter corridor applications. The SCL Series, designed for wall or stem mount applications, measures 9.1 inches x 5.3 inches and operates in a temperature range of 0 to 40 Celsius. The CRL Series is designed for recessed T-bar ceiling applications and lends a clean, architectural appearance.

By Nancy Crotti Sprint is a high-efficiency solar panel with an integrated racking system whose light weight allows it to be installed on commercial roofs that cannot support conventional solar systems. At 290 to 320 watts, its power capacities exceed those of conventional solar systems by as much as 20 percent. Its design requires no tools or grounding, and allows for as many as 30 percent more panels to be installed on one roof, increasing the system’s overall energy output.
