Sugar beets as a heat source

Since October 2013, VAUDE has been using certified biogas at its headquarters in Obereisenbach. This fuel is made solely from by-products of sugar production from sugar beets in Hungary.

92% renewable energy for heating

Directly at the sugar factory, biogas is physically used as process heat, reducing the amount of conventional natural gas used in the public power supply. The percentage of renewable energies in gas consumption at VAUDE in 2014 was 100%.

Because our waterproof bags production facility burned down in April 2015 due to lightning strike and was temporarily moved to a rented building, we had to use the (non-renewable) energy provided by the landlord for electricity and heating. This is one reason why our percentage of renewable energy fell to 92% in 2016.

Weather-adjusted energy consumption

In order to evaluate our thermal energy consumption independently from outside temperatures and the duration of the heating season, we align our consumption figures with the regional degree days for Ravensburg (GTZspez). This was 3,613 for 2016 according to the Ravensburg Energy Agency.

This resulted in higher weather-adjusted heating energy needs than our actual consumption – we used less energy for heating than what would be predicted from the outside temperatures.

More office space, more efficient heating

Nevertheless, our heating energy consumption did increase.
We will keep an eye on our heating energy requirements in the future and, with the help of technical measures as well as employee awareness, try to heat even more conservatively in the future.

Solar thermal energy for cyclist showering facilities

Since 2014 we have used solar thermal energy in a buffer tank for hot water, reducing our use of gas. We only supplement with gas when the cloud cover is too great and when a large number of employees take hot showers after their bike-commute to work or after sports. In 2016 we produced 590 kWh of solar energy.
