A heating degree day (HDD) is each degree that the average daily temperature is below the base temperature (65 degrees F) is one heating degree day. A cooling de gree day (CDD) air temperature differences between the outdoors and 78 degrees F over the summer season. Heating degree days and cooling degree days are used by energy professionals around the world for several reasons. Find the degree day chart here. Oak Ridge South Jefferson Circle Oak Ridge, TN Phone

It was originally published as a Google Knol where it received the Top Viewed Knol Award and the Top Pick Knol Award. We republished it here when Google Knol was discontinued, and have made some small edits since then. From the lists, indicate the first date (month, day, and year) for which you want to calculate degree-days, and the last date (month, day, and year).
The default dates supplied by the computer are usually March 15 of the current year and the last date for which the selected station can be expected to have data. Heating and Cooling Degree Days These metrics provide a simple way to distill a year's worth of temperature data to a single Degree days book that is useful for energy estimations.
We will see that the energy to heat and cool is proportional to the heating degree days (HDD) and cooling degree days (CDD) values.
Heating degree days (HDD) are a measure of how cold the temperature was on a given day or during a period of days. For example, a day with a mean temperature of 40°F has 25 HDD. For example, a day with a mean temperature of 40°F has 25 HDD.
If the average degree day value for a given day is less than zero, just record zero, not a negative number. Finally, to keep track of degree day accumulation, keep a running total of all degree days accumulated from the first of the year. In Wisconsin, we often don’t accumulate many degree days before April 1, so if you wish to take a break.
62° and above add 6 Degree Days • 54° to 57° add 4 Degree Days • 46° to 49° add 2 Degree Days. 58° to 61° add 5 Degree Days • 50° to 53° add 3 Degree Days • 43° to 45° add 1 Degree Day.
WHAT IS A K-FACTOR. It is simply a number showing how fast a customer uses fuel. Degree Day Systems • PO Box33 Village Park Road, Cedar Grove, NJ • DEGREE. Heating Degree Day - Weather Data Depot: free downloads of. For example, let's say that over one month at one building you had heating degree days and 15 cooling degree days, totaling degree days.
Over that same month, your building u kWh. 50, kWh divided by degree days equals 97 kWh/degree day. Say a second building of comparable size consumedkWh over the same period.

Growers and landscape technicians can use the Growing Degree Day (GDD) measurement of heat to predict which insects will be active at which point.
For example, at 90 GDD, Eastern Tent Caterpillars are active. Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air heating requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.
Related measurements include the cooling degree day (CDD), which. The DayWatcher is a fully automated Degree Day System that logs Heating and Hot Water Degree Days for Fuel Delivery suppliers. It also has the ability to calculate Cooling & Growing Degree Days for Energy and Agricultural industries.

If you decide to withdraw from the ceremony during this time, your degree will be conferred at the ceremony in absentia and you will not be able to attend a future date.
Determining Heating Degree Day (HDD) The formula for determining the Heating Degree Day (HHD) is: HDD = T base-T a. To calculate HDD: Determine the base temperature or inside temperature: T base = usually 65 ° F; Find the day's average outside temperature using this formula: T a = average outside temperature = T max + T min 2; Use the HDD formula to solve: T base - T a; Note: If the T a is.F and a high of 75 degrees F, then the average temperature for the day was (45+75)/2 = 60 degrees F.
If the threshold temperature was 50 degrees F, then 10 degree days would have accumulated. Check your thermometer and make this calculation each day. Add the daily value to the total from all the previous days. You can keep up with the progress.
