Building codes in the United States are a collection of regulations and laws adopted by state and local jurisdictions that set “minimum requirements for how structural systems, plumbing, heating, ventilation, and air conditioning (), natural gas systems and other aspects of residential and commercial buildings should be ...

3. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   A realistic indication of energy efficiency over an entire year can be achieved by using seasonal COP or seasonal coefficient of performance (SCOP) for heat. Seasonal energy efficiency ratio (SEER) is mostly used for air conditioning. SCOP is a new methodology which gives a better indication of expected real-life performance of heat pump ...

   Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:
