In my May 2016 article, “The Radiant Roads to School Design,” I was in the middle of designing a building with a radiant heated and cooled slab with DOAS/openable windows for ventilation for the College of Continuing and Professional Education (CCPE) at CSU Long Beach (CSULB).
This month’s Facility File will focus on the B2B June test for the renovation of an office building located on a major corporation’s U.S. headquarters campus. The existing HVAC system to be replaced is an antiquated hot water heating system serving baseboard radiation, unit heaters, and a rooftop HVAC unit.
Samsung has launched Fresh Access™, a ventilation product line designed to bring fresh air into commercial buildings. The Fresh Access line includes three fresh air solutions that will align with ASHRAE requirements for fresh air: packaged dedicated outside air system (DOAS), split DOAS, and energy recovery ventilators (ERV).
Judges, prosecutors, law enforcement officials, and others who spend their days in and out of courtrooms in San Diego waited more than a decade for a proposed new state courthouse to become reality. According to designers on the project, their patience was rewarded.
HVAC and trade educators know the importance of students learning and working on equipment they will encounter in the field. This exact focus on experiential learning informed the plans for an expansive new trades teaching facility at Sheridan College’s Brampton, Ontario, Canada, campus.
Energy recovery, sensors, and smart deployment of other options can let a system clear the psychrometric hurdle of designing for high outdoor air requirement and high moisture levels.
Dedicated outdoor air systems (DOAS) have been available for over 20 years, with the primary benefit being the ability to decouple outdoor air tempering from conditioned space thermal loads that can be handled by separate, secondary systems.
