Reduction on Gas Consumption

Reduction Natural Gas

� Adaptations

� Introducing day/night regime for DE building

� Switching off of heating in meeting rooms between 18:00h and 7:00h

� Switching off humidifiers in summer time

A degree-day is a measure of heating or cooling. A zero degree-day is when both heating and

cooling consumption is at a minimum, which is useful with power utility companies in

predicting seasonal low points in energy demand.

� Gas Savings

� 5.300MWh in 2007, 1563 MWh in 2013

� 70,5% savings (2007-2013)



Analysis of Cold Production

17 | Energy Savings

Analyses of Cold Production (1)

Old situation: Ice production during night, melting down during office hours


Analyses of Cold Production (2)

� Ice production during night is not efficient: only COP of 2,9

� Solution:

� use ice buffer for emergy cases and use direct chilling during day/night

� Saving on yearly base: 30.000€
