Climate change is expected to decrease heating demand and increase cooling demand for buildings and affect outdoor thermal comfort. Under the unmitigated RCP8.

Degree day

As outdoor temperature goes down, the amount of energy required for heating goes up. Similarly, as outdoor temperature goes up, the energy demand for most air conditioner and refrigeration systems increases. This indicator measures changes in the average annual energy requirements for heating and cooling of similarly constructed and insulated buildings from to Results are provided for British Columbia and each of the nine terrestrial ecoprovinces. The methods used to develop this indicator and more about energy requirements for heating and cooling and other climate indicators are available in Indicators of Climate Change for British Columbia Update PDF, 4. The R code for creating the graphs presented on this page is available on GitHub.

The Estimation of Base Temperature for Heating and Cooling Degree-Days for South Korea

We apologize for the inconvenience...

The degree-day is an index number originally developed by heating, ventilation, and air conditioning engineers Houghton, The heating degree-day was developed to assess energy needs necessary to heat business buildings and private homes. The greater the range in a mean daily temperature from 65, the greater the number of heating degree-days; hence, more fuel must be expended Ahrens, The cooling degree-day is used to assess energy needs required to cool buildings and homes.

However, temperature can predict more than boom or bust. Atmospheric temperature can predict the growth rates of many plants. For this reason, growers use a concept called growing degree-days GDD , sometimes called heat units. GDD relate air temperature to plant growth, development, and maturity.

A degree day is a measure of heating or cooling. Total degree days from an appropriate starting date are used to plan the planting of crops and management of pests and pest control timing. Weekly or monthly degree-day figures may also be used within an energy monitoring and targeting scheme to monitor the heating and cooling costs of climate controlled buildings, while annual figures can be used for estimating future costs. A degree day is computed as the integral of a function of time that generally varies with temperature. The function is truncated to upper and lower limits that vary by organism, or to limits that are appropriate for climate control.
