This article is part of The 100 Days Offensive. Got to Day 27 or Day 29.
Two people working 95% of the time from the home office: What is the energy impact?
On the positive side I have a home automation that gives me some data. I monitor the energy usage in 5min intervals and can compare it with the previous months. On the negative side we have the last four weeks being colder than the December, January or February and we are heating with electricity. On the positive side again, the time the heating is on (10 p.m. till 6 a.m.) does not overlap with our working hours (usually 8-12 hours between 7 a.m. and 7 p.m.).
Without spending too much time on writing software to evaluate the data, the best number I can give you are about 5 kWh per working day. That is quite a lot. But we have three large monitors running and since my working room is in the basement, the dehumidifier has to pull about additional 1.5l of water from the air per day to prevent molding. As electricity is quite expensive in Germany, this equals costs of about 30€ per month (based on 20 work days per month). I am curious what will happen when I try to deduct the costs from my next tax declaration.
