Figure N10. Signature of energy and water consumption (daily data, sample taken from
BuildingEQ).
The visualizations show the following things:
The signature of district heat clearly shows the set back of heating on
■
week-ends and the changepoint (at 18°C). A maximum of the heating
power of 1300 kW (at -12°C outdoor air temperature) can be derived
from the signature. The installed power is 2200 kW, i.e. 70 % more than
the necessary power. This corresponds to possible cost savings of about
30.000 EUR/a.
The base load of power consumption is approx. 90 kW or 3 W/m²
■
respectively.
The base load of water consumption could not be explained
