There were fluorescent light fixtures throughout the common areas in this building. The Owner should upgrade them to LEDs and where feasible to bi-level LED fixtures with occupancy sensors and light sensors.

The corridors are lit with fluorescent circle bulbs which could be upgraded to LEDs to save energy.

During the LL87 examination we measured the temperature of the domestic hot water in the sinks. Under NYC Code the temperature of DHW cannot exceed 140 F degrees. This building was in compliance.
