Codes & Standards: HVAC
The 2015 version of the International Energy Conservation Code will approve air curtains as an alternative to vestibules.
Fan efficiency grades (FEG) are a poor metric in determining the most efficient fan (in terms of actual power consumption) for a given airflow and pressure operating point. The best simple metric to ensure the lowest power consumption is the operating brake horsepower at the specified design point.
Construction and fabrication are governed and controlled by the American Society of Mechanical Engineers (ASME).
The selection process is a trade-off between the overall heat transfer coefficient, which influences the pump head on the HVAC system.
The 2013 version of ASHRAE’s indoor air quality (IAQ) standard contains several revisions to help users better meet its requirements.
Indoor air quality (IAQ) and energy management are key in K-12 schools and higher education university buildings. This information will help to provide an efficient, effective HVAC system in a school or a university building.
This example shows how upgrades were made to a deficient HVAC system in a step-by-step process.
How to select, design, and redesign lighting systems so they complement HVAC systems.
Significant changes to the 2012 International Energy Conservation Code (IECC) impact architects, engineers, code officials, and other building design professionals.
Major changes to ASHRAE Standard 90.1 include the sections on building envelope, lighting, mechanical, and energy cost budget.
