Monthly monitoring and adjustment of HVAC control sequences in 2006-07 cut energy use more than 10%. Total cost savings were over $65,000, and the firm avoided more than 1 million pounds of CO2 emissions.
PES performed campus-wide energy audits and provided clear justification for HVAC system re-tuning and certain capital investents. We identified additional annual savings of more than $40,000.
PES provided independent financial and lifecycle analyses of lighting and heat pump upgrade proposals for 4 buildings, to ensure the best project choice, maximize ROI, and assure long-term operational efficiency. To date, lighting upgrades have been performed in 4 buildings, and heat pump upgrades have been completed in 2 buildings.
Ongoing Measurement + Verification
PES benchmarks and tracks monthly energy performance and savings by building, to assure client expectations are met or exceeded. Annual electricity (kWh) savings for the last 12 months ending January 2013 ranged from 20% to 42% per building.
ENERGY STAR Certification
Due to significant improvements in energy performance, 2 of the 4 buildings with retrofits qualified for the ENERGY STAR label in 2012. PES validated the buildings’ energy performance scores and managed the certification process.
Most recently, we performed a campus-wide carbon footprint, which captures these energy savings and provides a tangible measure of progress. This offers significant opportunities to demonstrate the firm’s commitment to its employees, community and customers.
