Mission Germany Lights The Way

US Consulate Hamburg is converting security lighting fixtures with halogen bulbs and voltage regulators (at 82 watts each) to OBO-approved fixtures with compact fluorescent bulbs (at 42 watts each). The change yields an annualized savings of 3,600 kWh or a 1.3% reduction in electricity consumption compared to calendar year 2009. This step builds on a total 11.9% reduction in electricity consumption achieved at the Consulate Office Building (COB) during 2009.

This change is carbon neutral because the consulate converted to a green energy utility provider on January 1, 2009 – which, coincidentally was:

• a budget neutral change, going from 9.85 € Ct./kWh to € 9.84 Ct./kWh,
• a 146-ton reduction of carbon emissions for the switch to a green source provider, and
• a 10-ton reduction of carbon emissions for the lower electrical consumption during 2009.

Via Mission Germany’s collaborative Energy Savings Initiative, post Munich is already exploring whether it can apply this approach to a similar problem of high energy consumption security lighting.
