October 19, 2011 - To help ensure schools receive an A+ in energy efficiency, ASHRAE encourages owners, engineers, designers, architects and others on the building team to download the free “Advanced Energy Design Guide for K-12 School Buildings: Achieving 50% Energy Savings Toward a Net Zero Energy Building”. The guide is the second in a series that provides recommendations to achieve 50% energy savings when compared with the minimum code requirements of ANSI/ASHRAE/IES 90.1-2004, “Energy Standard for Buildings Except Low-Rise Residential Buildings”.Written in partnership with ASHRAE, the American Institute of Architects (AIA), the Illuminating Engineering Society (IES), the U.S. Green Building Council (USGBC) and the U.S. Department of Energy (DoE), the guide features easy-to-follow recommendations for various climate zones and how to implement tips via a series of real-life school construction case studies. Also included is information on integrated design, including best practices, as a necessary component in achieving 50% energy, and the inclusion of a performance path; specifically, offering guidance for early stage energy modelling and annual energy use targets to help with goal setting. “Advanced Energy Design Guide for K-12 School Buildings: Achieving 50% Energy Savings Toward a Net Zero Energy Building” is available as a free download at www.ashrae.org/freeaedg.
October 7, 2011 - Carrier—a global player in HVACR solutions (part of United Technologies Corp.)—introduced its Infinity gas furnace line, which promises “industry-leading energy efficiency and sound ratings”. With Greenspeed intelligence, the gas furnace line combines modulating and variable-speed technologies with a communicating control system to constantly adapt to a home’s conditions. The furnace line will deliver precise comfort with reduced energy use, boasts Carrier, and is the most energy-efficient furnace in Carrier history, with an Annual Fuel Utilization Efficiency (AFUE) up to 98%. The furnace’s quiet operation is made possible by technology that distributes heated air at the lowest possible setting for the majority of the heating season. In low-fire mode, where the furnace operates most often, sound ratings are as low as 38.4 db—less than the sound of a refrigerator, says Carrier.CARRIER
