Since January 2010, Blue Ocean Energy has successfully and dramatically lowered the overall energy costs at Enfield Properties by 47% compared to 2009. This savings has been achieved only through proactive energy management, including an aggressive procurement strategy. During these 3 years, except for a skylight replacement, no money was spent on equipment upgrades.
Enfield Properties has reduced their energy costs by approximately 2/3 over the past 7 years. The initial reduction in 2007 was achieved through a number of facility upgrades, including installing a new HVAC system.
Enfield Properties is a two-story, 67, 500 square foot office facility in Houston, Texas, which was built in 1981. As the Energy Manager for Enfield Properties since 2010, Blue Ocean Energy’s challenge was to lower Enfield Properties overall energy costs.
Energy costs were soaring at Enfield Properties. The owner of Enfield Properties wanted to be proactive when it came to managing and lowering the energy costs of the facility so he employed Blue Ocean Energy.
Our strategy for achieving these savings:
Reduce the kilowatt (kWh) hours
BOE successfully lowered the overall kWh consumption by 22% over the base year 2009. This savings was achieved by ensuring that the Energy Management System, thermostat, and light schedules were corrected to reflect occupancy hours at the building. The relatively mild climate of 2012 did cause part of this reduction, but the largest savings were achieved by optimizing the HVAC and lighting schedules.
Overall demand reduction
Over the past 3 years, BOE achieved a 29% savings by focusing on demand charges. The primary focus was to mitigate peak demand by programming the Energy Management System to enhance load-shifting and the corresponding demand reduction.
Cost per unit
Enfield Properties’ cost per unit in 2009 was close to $.15 per kWh, which we managed to reduce to $.10 per kWh in 2012, for a 33% reduction. This savings was achieved by identifying Enfield Properties’ risk profile and structuring the supply contract to reflect this profile. Enfield Properties has been on a floating price for part of the year and on a fixed price for the rest of the year (from their retail electric provider).
