Futures/Commodities Trading Strategy & Education, How to Calculate Cooling Degree Day (CDD). This package consists of the EU Strategy on adaptation to climate change (COM/2013/216 final) and a number of supporting documents. 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 … "Cooling degree days", or "CDD", are a measure of how much (in degrees), and for how long (in days), outside air temperature was higher than a specific base temperature. Example: In this case, the Average Daily Temperature is 80°F then the difference from 80°F to 65°F is 15°F. Total degree days from an appropriate starting date are used to plan the planting of crops and management of pests and pest control timing. These instruments create a risk management tool that utility, agriculture, construction, and other firms can use to hedge their activities affected by outdoor climate whether it be energy demand, growing season, or outdoor work time. There are several ways to calculate CDD. A day with a mean temperature of 80°F has 15 CDD. The evaluation found that the EU Adaptation Strategy has been a reference point to prepare Europe for the climate impacts to come, at all levels. Both cooling degree days and heating degree days are calculated by comparing the difference between the average outdoor temperature and a standard temperature, typically 65°F. It emphasized that EU policy must seek to create synergies between climate change adaptation, disaster risk reduction efforts and sustainable development to avoid future damage and provide for long-term economic and social welfare in Europe and in partner countries. EU Strategy on adaptation to climate change, Covenant of Mayors for Climate and Energy, Adaptation preparedness scoreboard country fiches. Cooling needs vary greatly depending on the geographical region. The ECA dataset contains series of daily observations at meteorological stations throughout Europe and the Mediterranean. A cooling degree day (CDD) refers to the degrees that a day's average temperature is above 65 degrees Fahrenheit, used to quantify the demand for energy. They can be computed in different ways, depending, among other things, on the specific target application and the availability of sub-daily temperature data. You must enable cookies before you can log in. Space heating and cooling is responsible for a large fraction of European energy use. This chart shows number of Cooling Degree Days in a year for the selected location and time period under the RCP 4.5 scenario. In April 2013, the European Commission adopted an EU strategy on adaptation to climate change, which has been welcomed by the EU Member States. It is the number of degrees that a day's average temperature is above 18°C. Cooling Degree-days (CDD) and Heating Degree-days (HDD) are meteorological indices defined as integrated temperature deviations from a base temperature over time.Formally, degree-days are defined as a summation of the differences between the outdoor temperature and some threshold (or reference base) temperature over a specified time period (such as at annual time scales). Heating degree days (HDDs) and cooling degree days (CDDs) are proxies for the energy demand needed to heat or cool, respectively, a home or a business. Degree days also have applications relating to plant growth ("growing degree days"). Specifically, it is the number of degrees a day's average temperature was above 65°F. Cooling degree days (CDD) are used to give an indication of the effect of outside air temperature on building energy consumption during a specified period of time. Using the information from the previous example, they could take weather data from previous years and current seasons to estimate their risk. The evaluation package comprises a Report on the implementation of the EU Strategy on adaptation to climate change (COM(2018)738), the Evaluation of the EU Strategy on adaptation to climate change (SWD(2018)461), and the Adaptation preparedness scoreboard Country fiches (SWD(2018)460). As a result of the methodological changes, the magnitudes of the trends between this version of the indicator and versions published before 2016 cannot be directly compared. HDD and CDD projections are derived from the ensemble mean of 11 high‐resolution bias‐adjusted EURO‐CORDEX simulations. The daily station normals from the National Climatic Data Center (NCDC) were corrected on June 28, 2003. The EC also supports adaptation in cities through the Covenant of Mayors for Climate and Energy initiative. Cooling degree days. Here are examples of two ways that are often used. It has been shown that well planned, early adaptation action saves money and lives in the future. Cooling Degree Day (CDD) Definition. Work specified here will require more than 1 year (from now) to be completed. The EEA is an agency of the European Union, European degree-day climatologies and trends for the period 1951–2011 (Dataset URL is not available), Changes of heating and cooling degree‐days in Europe from 1981 to 2100, GEOSTAT was launched at the beginning of 2010 by Eurostat in cooperation with the  European Forum for GeoStatistics (EFGS) , to promote grid-based statistics and more generally to work towards the integration of statistical and geospatial information in a common information infrastructure for the EU. But if the value is positive, that number represents the CDD number of that day. The units used in this indicator are heating and cooling degree days (° C*d/yr). The aggregation of regional changes in HDDs and CDDs to larger areas can be done using area weighting or population weighting (with a fixed population). Heating degree days have generally decreased and cooling degree days have generally increased throughout the North and West. That would be 8 cooling degree days (73-65). Cooling Degree Day. Cookies are not enabled. Cooling Degree Daysare a measure of the need for air conditioning (cooling) based on the extent to which the daily mean temperature rises above a reference temperature (65 F).For example, on a day when the mean outdoor temperature is 85 F, there would be 20 degree-days experienced. A moving average is a technical analysis indicator that helps smooth out price action by filtering out the “noise” from random price fluctuations. A similar measurement, heating degree day (HDD), reflects the amount of energy needed to heat a home or business. Degree days also have applications relating to plant growth ("growing degree days"). Rationale Justification for indicator selection. A cooling degree day (CDD) is a measurement designed to quantify the demand for energy needed to cool buildings. In February 2016, the Commission published an EU Strategy on Heating and Cooling, which aims to decarbonise the heating and cooling of buildings through different technologies and measures, in line with wider EU climate and energy policies. The degree days computed in real-time during Jan 12 to April 26 (2008) were erroneous due to corrupted temperature grids. DECISION No 1386/2013/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 20 November 2013 on a General Union Environment Action Programme to 2020 ‘Living well, within the limits of our planet’. Cooling degree days (CDD) are mainly used for the assessment of air conditioning systems (see Section 7.9). Spinoni et al., 2018: Changes of heating and cooling degree-days in Europe from 1981 to 2100. Degree day data is useful to indicate how seasonal weather affects building energy use, which impacts energy management, energy efficiency, and utility bill tracking. For example, from 2010 to 2013, the CDD ranged from 250 to 274 degree cooling days above normal when the U.S. saw some of its hottest summers since the mid-1980’s. These maps show the trend in heating degree days (left) and cooling degree days (right) from 1981-2100 for all EEA member and cooperating countries, based on the median of an ensemble of 11 EURO-CORDEX simulations. For all methods, if the value for any given day is less than or equal to zero, that day has zero CDD. Cooling degree days (CDD) is the terminology used to describe how much cooling is needed to maintain a certain level of indoor comfort. The evaluation also suggests areas where more work needs to be done to prepare vulnerable regions and sectors. Our low-carbon growth has long been decoupled from resource use, setting the pace for a safe and sustainable global society.’, Overview of EU sector policies in which mainstreaming of adaptation to climate change is ongoing or explored, Overview of activities of EEA member countries in preparing, developing and implementing adaptation strategies. The largest decrease occurred in northern Europe and possibly in Italy. (A daily mean temperature represents the sum of the high and the low readings divided by two.) Additional information. Space heating and cooling is responsible for a large fraction of European energy use. One of the objectives of the EU Adaptation Strategy is 'Better informed decision-making'. Evaluation of the EU Adaptation Strategy Package, Climate-ADAPT: Adaptation in EU policy sectors, Sign up to receive our news notifications. Note that this approach, being based on both minimum (Tn) and maximum (Tx) temperatures and not solely on the mean temperature (Tm), increases the accuracy of HDDs and CDDs for the purpose of gauging the impacts of climate change on energy demand, because the cooling of the environment depends more on Tx than on Tm, while Tn is more relevant for heating. Stippling depicts regions where the trend is statistically significant at the 5% level. A cooling degree day is every degree that the mean temperature is above 65 degrees during a day. Degree days reflect changes in climate and are used as a proxy for the energy demand for heating or cooling buildings. Climate simulations are associated with uncertainties related to the underlying emissions or forcing scenario, natural variability and model uncertainty. Code: nrg_chdd_a Last update: 16/06/20 Oldest data: 1979 Most recent data: 2019 Number of values: 2296 . They are used for calculations relating to the energy consumption required to cool buildings. Wilder’s DMI (ADX) consists of three indicators that measure a trend’s strength and direction. Weather derivative (futures) contracts could then be purchased to protect against significant losses if the company expected higher temperatures. This indicator uses an approach developed by the UK Met Office, which uses daily mean, minimum and maximum temperatures and does not exhibit a discontinuity. Heating and cooling degree days, 20 Nov 2012 - While CDD can describe the overall need for cooling as part of the planning for residential or commercial buildings, it is critical for the pricing of weather derivatives. However, they also depend on various other factors, such as building design and insulation, availability and type of heating and cooling systems, energy prices and income levels, and behavioural aspects. Weather future is a derivative contract where the payoffs are based on the aggregate difference in the measured weather variable over a fixed period. Heating degree days, https://www.eea.europa.eu/data-and-maps/indicators/heating-degree-days-2, European Environment Information and Observation Network (Eionet), Biodiversity Information System for Europe, European Pollutant Release and Transfer Register, Information Platform for Chemical Monitoring, Marine Water Information System for Europe, Fresh Water Information System for Europe. One caveat is that cooling degree days are extremely localized. These same could likewise be sold if the company expected significantly lower temperatures. The nominal settlement value for that month's weather derivative contract would therefore be $6,000 (300 x $20). This indicator looks at the following: Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. Both variables are derived from measurements of outside air temperature. It highlights that ‘Action to mitigate and adapt to climate change will increase the resilience of the Union’s economy and society, while stimulating innovation and protecting the Union’s natural resources.’ Consequently, several priority objectives of the 7th EAP refer to climate change adaptation. Climate Central analyzed 242 cities in the U.S. and determined that 96% experienced an increase in CDDs since the 1970s. This measure has relevance to the price of weather derivatives traded on the basis of an index made up of monthly CDD values. Heating and cooling degree days (HDD and CDD) essentially indicate how hot (or cold) it is outside for a given day and for how long it was at that temperature. It is based on the number of days where the temperature is above 65 degrees Fahrenheit, and the number of degrees above 65. It is the number of degrees that a day's average temperature is above 65o Fahrenheit (18o Celsius). The increase is most noticeable over the past few decades, suggesting that air conditioning energy demand has also been increasing recently (see Figure 1). The strategy aims to make Europe more climate-resilient. Please make sure javascript is enabled in your browser. ‘In 2050, we live well, within the planet’s ecological limits. Our prosperity and healthy environment stem from an innovative, circular economy where nothing is wasted and where natural resources are managed sustainably, and biodiversity is protected, valued and restored in ways that enhance our society’s resilience. Observed trends in heating and cooling degree days; Now I’ll show you the easy way to get heating and cooling degree day data. What cooling degree days are, and how they can help energy consumption habits Themes: Environment and energy . Previous versions of this indicator published before 2016 applied the methodology of Eurostat, which uses daily mean temperature only and has a jump discontinuity when daily mean temperature falls below the base temperature. Different definitions exist for computing HDDs and CDDs, which can lead to different magnitudes of calculated trends. Furthermore, heating is delivered to end users in different ways (individual boilers fuelled by oil, gas and coal, and electricity and district heating), whereas cooling is delivered currently almost exclusively through electricity. The evaluation package includes a Report from the Commission, a Commission Staff Working Document, the Adaptation preparedness scoreboard country fiches, and the reports from the JRC PESETA III project. They are commonly used in calculations relating to the energy consumption required to cool buildings. This web portal provides information on all adaptation activities of the European Commission. By taking a coherent approach and providing for improved coordination, it enhances the preparedness and capacity of all governance levels to respond to the impacts of climate change. So, if the high temperature for the day is 95, and the minimum is 51, the average temperature for the day is 73. In November 2018, the EC published an evaluation of the EU Adaptation Strategy. Most EU Member States have already adopted national adaptation strategies and many have also prepared action plans on climate change adaptation. Work specified here requires to be completed within 1 year from now. News releases Release calendar It can be used to filter trades or generate trade signals. Cooling Degree Day is a measure that helps to simplify the cost of projected energy consumption. Heating degree days (HDDs) and cooling degree days (CDDs) are proxies for the energy demand needed to heat or cool, respectively, a home or a business. Cooling degree days are a measure of how much (in degrees), and for how long (in days), the outside air temperature was above a certain level. In April 2013, the European Commission (EC) presented the EU Adaptation Strategy Package. Download table . Use the weather normalization data here to adjust your building's or industrial plant's energy usage data for changes in weather. Overall, cooling degree days have increased over the past 100 years. If every day in a 30-day month had an average temperature of 75o F, the month's HDD value would be 300 (10 x 30). Adaptation means anticipating the adverse effects of climate change and taking appropriate action to prevent or minimise the damage they can cause, or taking advantage of opportunities that may arise. If a given day's value is less than or equal to zero, that day has zero CDD. Subtract 65 from the average of a day's high and low temperatures. The resulting trends are considered robust in most regions, but there are open questions for some regions with poor station coverage. But if the value is positive, that number represents the CDD on that day. The heating and cooling requirements for a given structure at a specific location are considered, to some degree, proportional to the number of HDDs and CDDs at that location. from version 20.10.13, Software version: The climatological input data sets for computing past trends for HDDs and CDDs in Europe combine temperature data with daily resolution from three different station data sets — the JRC’s MARS meteorological database, the NOAA National Climatic Data Center (NCDC)’s Global Historical Climatology Network data set and the European Climate and Assessment Dataset of the Royal Meteorological Institute of the Netherlands — and from one gridded data set (E-OBS versions 17). In November 2013, the European Parliament and the European Council adopted the 7th EU Environment Action Programme (7th EAP) to 2020, ‘Living well, within the limits of our planet’.
