Is there a code book for HVAC?
ACCA in Building Codes For years, ACCA’s technical manuals and standards have been an integral part of the national model building codes’ requirements for proper HVAC design.
How do I calculate HVAC requirements?
6 Steps to Properly Size Your HVAC Unit
- Step 1: Calculate the square footage of the area to be cooled.
- Step 2: Next, multiply the square footage obtained for each area by 25.
- Step 3: Then, add 400 for each person who works in that particular area.
- Step 4: Finally, for each window, add 1,000.
What is standard in HVAC?
Designers in the HVAC industry must be familiar with codes and standards. Standards define the industry’s agreed-upon minimum technical requirements, procedures, guidelines, and instructions for engineers, designers, or manufacturers. They also establish the industry’s minimum standard of care.
What is the difference between a standard and a code HVAC?
While a code provides requirements for the products (e.g. material performance level) and processes (i.e. methodology of the design) involved in installation, standards benefit both the contractors and engineers who employ them, and also the end user.
What is ASHRAE stand for?
ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers)
What is ARI standard?
ARI stands for “Air-Conditioning and Refrigeration Institute.” The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) was formed in 2008 after a merger of ARI and the Gas Appliance Manufacturers Association (GAMA).
Can a deck go over an AC unit?
Building A Deck Over An Air Conditioner. Sometimes an existing air conditioning unit is installed in the location where you want to build a new deck. Your best option is to move the unit to another location out of the way. This might cost you a few hundred dollars, but will save you a lot of headaches in the long run.
Can an AC unit be under a deck?

What is the difference between code and model code?
Codes are standards that are adopted by jurisdictions and are legally enforceable; however, model codes are not legally enforceable.
What is BTU DOE and BTU 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.
How many cfm do I need per room?
One cfm is needed per square foot (1 cfm/sq ft) of floor area. This is the average air quantity required for a room or an entire building. This number is based upon an averaged heat load calculation for comfort cooling.
How many cfm do I need per person?
ASHRAE (formerly called the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends (in its Standard 62.2-2016, “Ventilation and Acceptable Indoor Air Quality in Residential Buildings”) that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per …
What are AHRI standards?
Air-Conditioning, Heating and Refrigeration Institute (AHRI) standards are used worldwide to verify manufacturers’ performance claims, enabling fair product comparisons across various manufacturers. These documents direct product design and manufacturing as well as specification for product type during procurement.
