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
