Current Attempt in Progress
A convention center is considering the installation of occupancy sensors to reduce the cost of lighting and temperature control in
rooms that may be frequently unoccupied. 2 different sensors are being evaluated. Sensor A has a fixed delay but can cause frequent
on/off cycling of the lights, HVAC, and ventilation systems. Sensor Bis a self-optimizing sensor that uses recent room utilization to
optimize the delays resulting in higher savings and less frequent cycling of systems. There are 80 rooms in the convention center.
Installation of Sensor A in each room will cost $ 75/room and resuit in annual savings of approximately 800 kWh/room. Installation of
Sensor B in each room will cost $ 190/room and result in annual savings of approximately 900 KWh/room. The cost of electricity is $
0.03/kWh. MARR is 10%/yr. Compare the future worth of each alternative (including do nothing) over a 5-year planning horizon using
an investment portfolio approach, including residual capital in the investment pool.
