Bloomberg – Brian Hartmann – 2010

Goals 

Brian Hartmann, a joint MBA/MS student at the Erb Institute, University of Michigan, spent the summer as a Climate Corps fellow at Bloomberg LP, a worldwide media, news, data and analytics company headquartered in New York City. Though Bloomberg had previously identified and implemented numerous energy efficiency projects around the world, Hartmann discovered various opportunities for even greater efficiency.

Solutions

Hartmann analyzed illumination in different office areas and compared his findings with OSHA standards. This allowed him to determine areas where Bloomberg could modify its current lighting situation based on recommended light levels using dimmers and sensors. Hartmann also worked with an international team to identify energy efficiency opportunities in Hong Kong. This recommendation focused on switching to lower energy use light bulbs in some office spaces. In the New York Headquarters, he recommended sealing an inefficient duct system, raising chilled water temperatures and implementing a demand controlled ventilation system.

Potential Impact

In total, he identified and analyzed projects with the potential to save Bloomberg over $1.2 million per year while lowering total energy consumption over 6.2 million kWh per year and reducing CO2 emissions by over 2,300 metric tons per year.
