Funding programme for projects on climate protection in the municipalities

KSI (Climate Protection Initiative): Conversion of interior illumination to LED in headquarters of Stadtwerke Energie Jena-Pößneck GmbH 
Stadtwerke Energie Jena-Pößneck GmbH participates in a funding programme for municipial climate protection projects. For more information on the programme and the project promoter Jülich, follow this link:

Duration: 01.05.2019 until 30.04.2020
(Prolongation of project due to Corona until bis 31.12.2020)

Partners: Federal ministry for Environment, Nature Conservation and Nuclear Safety due to a decision of the German Bundestag and Stadtwerke Energie Jena-Pößneck GmbH

Signature: FKZ 03K10590

Objective and content of the project:  At the Stadtwerke Energie headquarters in Jena, Rudolstädter Straße 39, the 20 year old office illumination is to be replaced by energy saving LED lamps. This change of illumination facilitates energy savings of about 80% and thus makes it possible to save approx. 37,000 kg CO2 per year. Furthermore, the electronic control will be renovated and all single control units in the office rooms will be replaced in order to bring them up to date. 

Federal Climate Protection Initiative (KSI) 
Since 2008, thanks to the Climate Protection Initiative, the Federal Ministry of Environment has been initiating and supporting various projects that contribute to the reduction of greenhouse-gas emissions. Their programmes and projects cover a broad spectre of climate protection activities: from developing long-term oriented strategies to specific support and investive funding measures. This diversity guarantees good ideas. And: The Federal Climate Protection Initiative contributes to making climate protection a local issue. Both consumers and enterprises, municipalities or educational institutions can profit from it.
