What are ASHRAE standards for?
ASHRAE standards and guidelines include uniform methods of testing for rating purposes, describe recommended practices in designing and installing equipment and provide other information to guide the industry.
What is the title and purpose of ASHRAE standard 62?
ANSI/ASHRAE Standards 62.1 and 62.2 are the recognized standards for ventilation system design and acceptable indoor air quality (IAQ). Expanded and revised for 2019, both standards specify minimum ventilation rates and other measures in order to minimize adverse health effects for occupants.
What does ASHRAE mean in air conditioning?
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE /ˈæʃreɪ/ ASH-ray) is an American professional association seeking to advance heating, ventilation, air conditioning and refrigeration (HVAC&R) systems design and construction.
What is ASHRAE code?
Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years. This standard provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings.
What is ASHRAE standard for outside air?
By example, the HVAC system, in a building built in 1985, could provide a maximum of 7 cubic feet per minute (CFM) per person outdoor air, while the current ASHRAE 62.1-2013 Standard requires 17 CFM per person outdoor air.
What is BTU vs ASHRAE?
BTU ASHRAE rating only considers 1 condition (80°F dry-bulb, 67°F wet-bulb). In contrast, BTU SACC rating considers 2 conditions (95°F dry-bulb and 83°F dry-bulb) while also using the weighted average (0.2 and 0.8 weighted factors) to account for other real-life conditions.
What is the difference between BTU and ASHRAE?
ASHRAE BTU is like how many BTU it actually outputs, and DOE is more like what it feels like due to the exhaust system being completely different (and less efficient) than a window unit.
When did ASHRAE standard 90 begin?
1975
The original standard, ASHRAE 90, was published in 1975. There have been multiple editions to it since. In 1999 the ASHRAE Board of Directors voted to place the standard on continuous maintenance, based on rapid changes in energy technology and energy prices.
Is ASHRAE a code?
ASHRAE Standard 90.1 defines how engineers should design buildings to achieve energy efficiency goals. In 1975, ASHRAE 90-75: Energy Conservation in New Building Design was published as the first national energy code.
What is the role of ASHRAE for ventilation?
ANSI/ASHRAE Standard 62.2-2019, Ventilation and Acceptable Indoor Air Quality in Residential Buildings, defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in residential buildings.
