Technical Brief Details How DX AC Systems Can Meet ASHRAE IAQ and Energy Savings Standards

WOBURN, MASS. February 5, 2013 ‘ Engineers designing commercial HVAC systems for use in schools, hospitals, factories or office buildings face a host of conflicts and tradeoffs when trying to comply with both ASHRAE Standard 90.1 for Energy Efficiency and ASHRAE Standard 62.1 for Indoor Air Quality (IAQ). To help engineers achieve a successful balance between the two, a new technical brief, ‘No More Tradeoffs: Designing DX AC Systems to Meet ASHRAE’s IAQ and Energy Savings Standards is now available to download from Rawal Devices, Inc. at http://resources.rawal.com/dx-ac-technical-brief.


Over the past decades, ASHRAE 90.1 promoted energy efficiency as a predominant design factor in air conditioning equipment. Standards for building design, insulation, glass, and ventilation were affected by the amount of thermal energy brought in from the outside air. More recently, ASHRAE 62.1 emphasized IAQ requirements and focused on proper ventilation and humidity control for operations and health issues. Studies meanwhile have confirmed the problems caused by tight, energy-efficient buildings that do not have correct ventilation. As a result, engineers face a balancing act between energy savings and IAQ in AC system design.
