Key Challenges Facing Facility Professionals

How Efficiently is Space Utilized?

• Real estate is the #2 cost, second only to payroll

• Some experts are concluding that “50% of all workspace currently goes unused”

P idi k t b t $8 000 $14 000• Providing a workspace costs between $8,000 - $14,000 per year (Gartner Group)

• Eliminating 100 workspaces saves $1 million annually

• As more workers become more mobile, reducing real estate costs is a real possibility

h i d d d h ili d• But……there is not good data today on how spaces are utilized—until Redwood

Key Takeaways

• Traditional lighting controls are not equipped to take full advantage of LEDsg

• As the market continues to adopt LED technology it’s time to look into new technologies developed specifically for LEDs

• Today’s environment provides the Perfect Storm for intelligent• Today s environment provides the Perfect Storm for intelligent building systems and smarter lighting due to:– Rising costs of energy and new energy codes– Corporate “green” and LEED building initiatives– Need for facility professionals to do more with less

• Low voltage lighting systems provide all the control and more relative to traditional systems, but also provide building intelligence tools that create additional value for building ownersowners
