When the owners of 221 Main wanted to sell the building they knew that their ongoing investment in smart lighting controls and the related energy savings would be a great selling point.
221 Main is a multi-tenant seventeen-floor class-A office tower. Each floor covers approximately 23,700 square feet. Adura Technologies’ wireless lighting controls have been installed in five suites in the building, covering a total of 43,300 square feet. As the building spec, Adura is proposed in the tenant improvement packages of new leases.
The 221 Main management team wanted more granular control of the building’s lighting. Previously, the building used wired occupancy sensors and had overly large sweeps. This meant that most of the building was controlled by one circuit so if there was one person in the building after the scheduled sweep, lights in most of the building would go back on.
Adura system currently controls approximately 400 light fixtures on several floors. Because the Adura system offers flexible groupings of sensors and fixtures, only 84 sensors will be needed to wirelessly control all 400 fixtures. The control strategies used in the office suites at 221 Main are occupancy detection, daylight harvesting, demand response and Task Tuning. The Adura system is currently in use in office suites for Pankow Construction, Zenith Administrators, MG Design, Triage Consulting and Hair Club for Men.
The Adura Wireless Lighting Control System has directly led to the Pankow office suite at 221 Main earning three LEED points towards a LEED Gold certification, with occupancy sensors accounting for one point and daylight harvesting earning two points. The system has contributed to other parts of the LEED certification as well. In addition to its LEED contributions and upgrades to office occupant’s comfort and safety, the system has led to an average energy savings of approximately 58 percent across the current suites.
