Achieving top-level energy performance in a multi-tenant commercial building has its challenges. Some of the best-performing commercial buildings have one important element in common: owners and tenants working together toward a unified goal of energy efficiency. However, owners and tenants face a range of barriers to meaningful coordination that delay or prevent uptake of energy efficiency and cost saving measures. As part of this session, panelists will highlight creative solutions that they have implemented to break down barriers between themselves and enable greater efficiency and sustainability improvements than either party could achieve on its own.
