HEATING DEGREE DAY IN HUNGARY

Environmental Engineering and Management Journal, 2014
In Central European countries, heating represents approximately 75% of the total energy use of a residential building, with average thermal characteristics of the envelope. The expected energy use can be determined using complex simulation programs, but an easier way is to use specific degree day values.

Using modified multiple heating-degree-day (HDD) and cooling-degree-day (CDD) indices to estimate building heating and cooling loads

, 2020
There is substantial confusion in the literature concerning the appropriate reference temperatures to use for the computation of heating-degree-day (HDD) and cooling-degree-day (CDD) indices, with the former ranging from 10 to 20 °C and the latter ...

A simplified HVAC energy prediction method based on degree-day

Sustainable cities and society, 2019
A building heating, ventilation, and air-conditioning (HVAC) system consumes large amounts of energy. Energy consumption prediction is an effective strategy for operation optimization and energy management in a building. The energy consumption of an HVAC

A dataset of spatial distribution of degree-day factors for glaciers in High Mountain Asia

China Scientific Data, 2019
: The degree-day model, a widely used approach for ice and snow melt computation, rests upon a relationship between snow or ice melt and air temperature that is usually expressed in the form of positive temperature.

Degree-Day Models

1998
The development of plants and Poikilothermic (cold-blooded) animals is highly dependent on temperature. It has been said that “the hotter it is the faster they grow.” This is true, up to a point, where higher temperatures retard or even stop development. Temperature-driven models are available for a large number of plants such as corn, cotton, alfalfa,

Hand calculating degree days

Agricultural and Forest Meteorology, 1985
Abstract Degree day accumulations can be used by growers to monitor the development of biological processes and thus can be used in crop and pest management. The adoption and use of degree days by individual growers and agricultural advisors, however, has been limited partly because of computational difficulties involved in the derivation of degree ...

Degree-days in Britain

Building Services Engineering Research and Technology, 1981
Temperature records at several sites have been analysed in terms of monthly and annual degree-day values to base temperatures in the range 5 to 20°C. Results for London (Heathrow) are presented in some detail and compared with estimates made with various published procedures. The consistency across Britain of year-to-year variations is examined.

Estimating monthly degree-days

Building Services Engineering Research and Technology, 1983
A new method is proposed for the estimation of monthly degree-day values from monthly mean temperatures. This can be used to calculate figures for sites which are distant from the 17 sites in the UK for which published data are available, and to modify published figures to non-standard base temperatures.
