Long Range Facility Planning
David Chesley PE, RCDD, LEED AP
Associate Principal / Sr. Electrical Engineer
• Track the age of mechanical & plumbing equipment to help plan for eventual replacement
• Review and modify HVAC equipment schedules
• Review and modify space heating and cooling set points
• Perform and track routine maintenance
• Track utility bills closely• Building EUI comparisons
LONG RANGE MECHANICAL PLANNING
• Learn about technical assistance programs available from utility companies and state government
• Interview building staff to identify problem areas
• Conduct a recommissioning audit to identify low cost/no cost measures to make adjustments to the building’s existing systems
• Pre-bond planning
LONG RANGE MECHANICAL PLANNING
• Look at first cost, simple payback, and life cycle costs to help prioritize and determine ROI
• Consider potential capital improvements such as changing out boilers, chillers and control systems nearing the end of their service life
• Work with the design team to find strategies with multiple benefits

LONG RANGE ELECTRICAL PLANNING
• Schedule relamping & cleaning luminaires
• Batteries: 5 to 7 year life• Thermal scan for loose
connections• Accurate records of panel
schedules• Safety first: commission arc
flash labeling
Maintenance
• High capacity floor boxes• Coordinated power and telecom
density • Busway with continuous track for
server rooms
Flexibility
LONG RANGE ELECTRICAL PLANNING
• Shift from PCs to Tablets• USB outlets• Furniture integrated solutions
LONG RANGE ELECTRICAL PLANNING
Flexibility
• Right-sizing capacity and circuit counts• The 35% rule• Surge suppression for longer equipment life• Integrating power/energy sub-meters
LONG RANGE ELECTRICAL PLANNING
Capacity and Function
• LED lighting: flexibility, not just efficiency• Digital controls: intuitive, and yes, cheaper• Auto dimming for daylighting• Manual dimming for the instructor
LONG RANGE ELECTRICAL PLANNING
Simplicity
