16 electric vehicle charging stations in Ballantyne
Uses T-8 high efficiency 28-watt light bulbs, which have a rated life that is 50% greater than the market standard and conserve 13% in energy usage
8 parking decks feature T-5 LED lamps, which consume half the wattage of fluorescents (energy saved with these lamps could power 85 homes for 365 days)
Replaced thousands of bulbs with LEDs campus-wide, significantly increasing the individual lifespan of bulbs and decreasing energy consumption by over 50%
Over 50% of parking lot pole lights (total 920) have been converted to LED with a goal of 100% by 2020
100% of building decorative pole lights have been converted to LED (over 400)
Occupancy sensors are used to control lighting in restrooms, janitor’s closets, telephone rooms and other areas
Active in Duke Energy’s Smart Energy in Offices (SEiO) campaign, dedicated to helping reduce energy consumption in office buildings through education
Uses energy efficiency building glass to minimize heat transfer into each building from direct sunlight while allowing maximum daylight to enter to reduce the load on lamp fixtures
Installed Tridium, an aggressive energy management system, in most of its buildings to examine the energy usage of outlets, lighting and core/shell HVAC energy through the use of separate meters. Monitoring enables us to make localized adjustments to conserve energy.
Uses Variable Frequency Drive in a large majority of its buildings to control motors to help gain more efficient use of energy; these are in place for the air handling units, pumps and other HVAC equipment. All water heaters are adjusted to the lowest possible temperature settings, and the hot water heaters are turned off in all unoccupied offices.
Staggered building HVAC starts to reduce demand spikes
At the LEED-certified buildings, the TPO roof systems also prevent the absorption of heat, keeping each building cool during summer months to reduce the cooling load necessary
