Greenfield analysis for planned service hall
DB Schenker Rail GmbH is Europe`s leading freight railway. According to the challenging energy efficiency goals of Deutsche Bahn (German Railway), the Siemens supplier aims C02-free operation by 2050 and already offers CO2-free transportation today.
The planned new service hall on the freight railway service center site in Nuremberg needs to meet highest energy efficiency requirements in order to increase the buildings` economic efficiency. Therefore, the planning documents for the new construction were to be examined in a greenfield analysis and evaluated with regard to their energy savings potential.
Energy efficiency experts from Siemens thoroughly analyzed all planning documents and data available in the summer of 2010 to provide for the highest possible energy efficiency in comparison to best practice solutions. The planning documents were also aligned with effective norms like the German Energy Conservation Regulations (EnEV). The analysis resulted in specific suggestions on how to exploit the identified energy savings potential.
The evaluation included the building envelope as well as utilities and off-sites such as heat generation, water heating, ventilation and extraction system, compressed air production, lighting, and washing plant.
The suggested improvement measures allowed for energy efficient building planning and design, and thus, reduced energy costs in the future. The energy flows were made transparent and comply with regulations. Economic and technical key data reinforce all recommendations.
Optimum exploitation of potential for higher energy efficiency through
Inspection of the basement insulation in the workshop hall
Separate supply of hot water
Daylight-depending lighting control
Presence detector in storage and social areas as well as hallways in the event building
Speed-controlled compressors or upstream control for compressed air production
Perennial use of the compressors waste heat for water heating
Use of electronic devices in stead of pneumatic tools or dispenser pumps wherever possible
