A photovaltaic roof system was installed in 2006. Solar cells are spread on an area over 1800m2 on the roof of the company. They generate an average of 100.000 kW per year. This represents a saving of over 1500 t CO2 since the solar cells have been in operation – compared to a conventional coal-fired power plant. Another comparison: 150 hectares of mixed forest absorb approximately 1500 t CO2 per year.
In 2007 the company made the adjustment from oil heating to heat pumps. Latter are being used to air-condition or to heat the building. There has not been any oil heating anymore inside the entire building ever since. Furthermore, a high number of ceiling fans ensure in the colder seasons that the heat is being pushed downwards. In the warmer seasons the ceiling fans ensure a continuous air circulation.
In the 2000s the building automation was expanded to include an automatic adjustment of the external shutters. They react according to the time of the day and the weather. Being closed during nights, they help to keep the heat in the house in the cold seasons. In the summertime they keep the warmth out. The roof-lights regulate themselves in a same way to ventilate the indoors.
The combination of these measures has reduced the power consumption by approximately 25.000 kW per year. This saves almost 30 t of CO2 emissions per year.
Furthermore investments were made by purchasing an electric car to be added to the Henninger vehicle fleet. From 2020 on, employees will have the possibility to purchase business-bicyles.
