A measure that gauges the amount of heating or cooling needed for a building using 65 degrees as a baseline. Electrical, natural gas, power, and heating, and air conditioning industries utilize heatin [..]

Degree days are measured as the number of degrees above or below a standardized temperature on any given day. In winter, US traders track heating degree days week by week, or month by month, normally [..]

A degree day is a measure of average temperature over a day, and is usually related to a temperature threshold. For instance, an actual average temperature of 5°C on a day is 2 degree days warmer than [..]

Term created to assess and acknowledge expected demand for energy. A degree day value is the difference between a day's average temperature and a previously set temperature (in the U.S., 65 degrees Fahrenheit). Degree days above 65 degrees are called Cooling Degree Days because they are days when people are likely to use energy for air conditi [..]

A unit measuring the extent to which the daily outdoor average temperature falls below an assumed base, normally 65 F for heating. One degree-day is counted for each degree falling below (for heating) [..]

Deviation of one degree temperature for one day from an arbitrary standard, usually the long-term average temperature for a place. De Jure Segregation:

A measure of the deviation of the mean daily temperature from a given standard, with each variance from the standard during a single day recorded as one degree day. Used to estimate energy requirements for heating a building.

See "Heating Degree Days."

Used to estimate energy requirements for heating and cooling a building, this is a measure of the deviation of the mean daily temperature from a given standard, with each variance from the standard during a single day recorded as one degree day.

It gauges the amount of heating or cooling needed for a building using 65°F (18°C) as a baseline. To compute heating/cooling degree-days, take the average temperature for a day and subtract the reference temperature of 65°F. If the difference is positive, it is called a Cooling Degree Days. If the difference is negative, it is called a Heating Degr [..]

The difference between indoor design temperature and each day's average outdoor temperature. Abbreviated: DD.

A measure that gauges the amount of heating or cooling needed for a building using 65 degrees as a baseline. Electrical, natural gas, power, and heating, and air conditioning industries utilize heating and cooling degree information to calculate their needs. For more specific definitions and how to calculate degree days, see the definitions for Hea [..]

A measure of the cold weather based on the extent to which the daily average temperature falls below a reference temperature, usually 65 degrees Fahrenheit.

A measure of the need for air conditioning (cooling) based on temperature and humidity. Although cooling degree days are published for many weather stations, a specific procedure has not been generall [..]

A measure of the coldness of the weather experienced, based on the extent to which the daily mean temperature falls below a reference temperature, usually 65 degrees F.

A parameter developed by heating and cooling engineers to relate energy use to temperature.  May be indexed to any temperature; the most common is 65°F. One degree day occurs when the daily mean tempe [..]

a measure of the departure of the daily mean temperature

A measure of the departure of the mean daily temperature from a given standard. That is one degree day for each degree (Fahrenheit or Celsius) of departure above or below the standard during one day.

a measure of the departure of the daily mean temperature from the normal daily temperature; heating and cooling Degree Days are the departure of the daily mean temperature from sixty -five degrees Fah [..]

A measure of the departure of the mean daily temperature from a given standard. That is one degree day for each degree (Fahrenheit or Celsius) of departure above or below the standard during one day.

A measure of the departure of the mean daily temperature

A measure of the departure of the mean daily temperature from a given standard. That is one degree day for each degree (Fahrenheit or Celsius) of departure above or below the standard during one day.

A unit, based upon temperature difference and time, used in estimating fuel consumption and specifying nominal heating load of a building in winter. For any one day, when the mean temperature is less [..]
