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.

AN IMPROVED MODEL FOR ESTIMATING DEGREE DAYS

Acta Horticulturae, 2002
Although using hourly data offers the greatest accuracy for estimating growing degree days, daily maximum and minimum temperature data are often used to estimate degree days by approximating the diurnal temperature trends. In this paper, an empirical model (TM model), recently developed for estimating hourly mean temperature, is used to calculate ...

Degday: A Program for Calculating Degree-days, and Assumptions Behind the Degree-day Approach

Environmental Entomology, 1986
A BASIC computer program (DEGDAY) for calculating degree-days on microcomputers is presented. The program calculates heating degree-days with the rectangle, triangle, and sine wave methods and calculates cooling degree days with the sine wave method. Assumptions and approximations associated with degree-day calculations are noted.

Determining degree-day thresholds from field observations

International Journal of Biometeorology, 1999
This paper compares several methods for determining degree-day (°D) threshold temperatures from field observations. Three of the methods use the mean developmental period temperature and simple equations to estimate: (1) the smallest standard deviation in °D, (2) the least standard deviation in days, and (3) a linear regression intercept.

An Explicit Distribution to Model the Proportion of Heating Degree Day and Cooling Degree Day

Communications in Statistics - Simulation and Computation, 2014
With a view to estimating the energy consumption, we derive the explicit distribution of the proportion X/(X + Y) when X and Y follow the new Bivariate Affine-Linear Exponential distribution. An application of this distribution to model the proportion of heating using the heating degree day and the cooling degree day data in the State of Alabama for ...

Characteristics of Heating Degree Days and Cooling Degree Days in Beijing During Last 50 Years

2011 Fourth International Joint Conference on Computational Sciences and Optimization, 2011
Degree-day is a quantitative index demonstrated to reflect the demand for energy to heat or cool houses and businesses. In this paper, the 18°C threshold temperature is chosen in Beijing. The homogenized mean daily temperature series during 1960-2009 in Beijing Weather Observatory is collected to calculate HDD and CDD.
