The extension of Züblin's central office meets high structural and energy efficiency standards. The construction group was awarded the certificate in Gold by the German Sustainable Building Council (DGNB) for the extension. The BINE Projektinfo 6/2017 "Servers heat office buildings" presents the energy concept along with monitoring results for the new five-storey building.
Lighting plays crucial role in the energy balance
The office building has low heat requirements, which are almost entirely covered by waste heat from the data centre. When this supply does not suffice, a combined heat and power plant in the neighbouring building provides the required thermal energy. With an average U-value of 0.4 W/m2K, the building envelope of the reinforced concrete structure reaches the level of a passive house. The exterior walls consist of prefabricated timber frame elements, which were transported to the construction site with pre-installed windows, solar shading and a sheet metal covering, and were installed there.
Lighting often plays an important role in the energy balance of highly insulated office buildings. This also applies to the Züblin building: the lighting sometimes consumed three times as much as assumed. Floor lamps at the workplaces were largely responsible for this. As soon as an office is occupied, it causes a base load of about 30 W. The final energy consumption for heating and cooling was slightly lower than previously calculated. Online surveys showed that the users were very satisfied with the thermal comfort and light conditions regardless of the season.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
