Accenture’s energy efficiency strategy rests on the four pillars of office selection, office improvements, smart metering and green IT. All the initiatives together focus on combining good design with more efficient operations, with machines and humans working together to make a difference.
The company leases almost all of its space around the world, which often means it has limited influence on the parts of buildings controlled by landlords. That is where intentional office selection comes in: Accenture looks for offices that can run efficiently, whether because the landlord offers tenants more freedom to act on energy efficiency or the building is environmentally certified to LEED or BREEAM standards. In large, metropolitan areas, the company prioritizes these LEED- or BREEAM-certified spaces.
When it comes time to fit out a newly-leased space—or retrofit an existing one—Accenture aims to complete the project guided by LEED and BREEAM principles. The company is also constantly looking for ways to improve its offices. That can range from implementing the latest in lighting design, including LED and Power over Ethernet (PoE) systems, to installing HVAC systems designed to minimize energy consumption while maximizing comfort, using presence detectors and set-back controls to operate at a minimum level when a space is unoccupied. In Data/Hub rooms, hot and cold aisles are introduced between IT racks to conserve energy and lower cooling costs.
By August 2014—In the early days of effective LED lighting—Accenture introduced the technology across its office portfolio in the Philippines; In 2017, the company retrofitted very large AC fans in buildings in India to electronic-commutated (EC) fans, reducing consumption enormously; in Germany and New York City, Accenture is installing Power over Ethernet (PoE) LED lights that are powered by low voltage data cables instead of conventional wiring; and mostly recently, in Spain and the US, we are installing air quality and occupancy sensors to optimize health while conserving energy. Accenture applies lessons and insights from the most promising use cases to benefit other offices around the world.
