How can anyone justify sustainable building retrofits in today’s market? Dana Robbins Schneider, vice president, Jones Lang LaSalle, discusses her involvement in the Empire State Building’s green retrofit and how it can serve as a model for building owners who want to achieve deep energy savings while earning a payback in five years or less. Even though funds are tight in the current economy, she argues that a realistic business case can enlighten building owners, showing them that the initial investment costs can deliver savings later down the line. Last month, she spoke at the ULI 2011 Fall Meeting about the latest technologies available to reduce costs to enhance control and performance of existing office building lighting and HVAC systems.
