Telkonet Inc has released The EcoWave™ occupancy-based wireless unitary HVAC controller. The company says the controller is ideal for achieving the balance of energy efficiency and occupant comfort in fan coils, heat pumps, PTACs, and other unitary equipment used in spaces with unpredictable occupancy, such as hotel rooms, dormitories, residence halls, assisted living, public housing, and condominiums. It can be installed as a standalone controller or be networked with the ZigBee® based EcoSmart Intelligent Energy Management System for cloud-based total facility management.
DuctSox has introduced the OvalSox™, fabric duct designed for low clearance HVAC ventilation in industrial and commercial building applications. OvalSox, which ranges from 11 to 22 in high and 47 to 93 in wide, saves 13 to 27 in of head room versus round HVAC fabric and metal duct alternatives, according to the company. Officials also claim there is no air volume or air dispersion lost with OvalSox versus conventional duct that hangs too low and obstructs industrial overhead conveyors or high rising equipment. OvalSox is also ideal for datacenters with high rising security cages or low hung ceilings in offices and other commercial designs.
Powerhouse Dynamics has expanded the remote equipment control functionality of its enterprise energy and asset management system. In addition, the company reported that the system has been renamed SiteSage™, replacing the eMonitor™ name under which it has been known.

Mitsubishi Electric U.S. Cooling & Heating Division is now offering the CITY MULTI® VRF Dedicated Outdoor Air System. The system is designed to supply outdoor ventilation air to a building independent of the HVAC air distribution or conditioning system.
Stinger UV-C fixturing from UV Resources is designed to destroy surface microbes and degrade organic materials that impede HVAC system efficiency, as well as contribute to allergies, poor IAQ, and airborne-transmitted disease.
The High-Output DEF (Double Ended Fixture) ultraviolet lamp series from UV Resources can be easily installed in most any HVAC system to destroy coil/drain pan microbial infestations and disinfect moving air streams.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
