A FORTRAN program is described which uses maximum and minimum temperatures to compute heating and cooling degree days (between and below thresholds, respectively). The temperature cycle is assumed to be a sine wave in which the 1st and 2nd minimum are not necessarily the same. The method is co...
Due to climate change, the average global temperature will rise in the coming decades. This should also significantly increase the number of so-called cooling degree days. These measure the number of hours above a certain ambient temperature threshold at which a building must be cooled to keep t...
We have developed summary tables (sorted by heating- and cooling-degree-days) to estimate the potential of heat-island reduction (HIR) strategies (i.e., solar-reflective roofs, shade trees, reflective pavements, and urban vegetation) to reduce cooling-energy use in buildings. The tables provide...
In climates with less than 1000 cooling-degree-days, the electricity savings were not significantly higher than winter heating penalties. For gas-heated office buildings, simulations indicated electricity savings in the range of 1100–1500 kWh/1000 ft 2 and 360–700 kWh/1000 ft 2, for Pre-1980...
摘要: This volume provides basic mathematical formulation, program listing, input data for the subject pocket calculator energy analysis procedure. The data include solar and surface weather parameters, degree-days to variable bases, sunlit factors and earth temperature....
The analysis of the differences in degree-days and average temperatures of the heating period showed that their difference for the two periods under consideration is insignificant and the decrease in degree-days amounts to an average of 100–15°C-day across the territory of Russia and an ...
A total of 200 water spectral data were obtained over two days. The significance of these data is that, on the one hand, they can calibrate UAV data to reduce the data uncertainty caused by the atmosphere, shadow, light intensity, etc. On the other hand, collecting water samples around ...
During the tuning phase of the software procedure, it was found that for an experienced operator the same nonautomated procedure requires at least 6–8 working days. The results are returned as vectorial data, which contain not only the monetary damage for each single building, but all the ...
