Heating degree days: the basis
for successful optimization
Use: optimization of building’s energy efficiency
Heating degree days are used to calculate the impact of the climate
on a building’s energy consumption. Heating degree days in connection
with a building’s energy usage show the success of the optimization
measures taken and reveal the weak points of a plant at an early
stage. The application calculates the number of heating degree days
from the difference of daily average of outside temperature and
daily average of room temperature. If the daily average lies below
the heating limit, the day is classified as a heating day. The calcu-
lated heating degree day is added to the total number of heating
degree days and stored.
– Reference value for making consumption comparisons and basis
for energy data
– Helps reveal weak points at an early stage to support energy-
optimized building operation
Sustainable energy savings –
with Desigo
The Desigo building automation and control system controls and
monitors reliably not only the entire HVAC plant, but also all other
building systems, thus representing the brain of a building. Desigo
affords effective control as well as active optimization of energy
usage and energy costs. With innovative energy saving functions
and the versatile, proven applications, Desigo delivers sustainable
building energy savings. This is also confirmed by EN 15232 that
Desigo conforms to in the highest efficiency classes.
