RAND's energy audit at 119 West 71st Street found
more than $13,000 in annual energy costs savings.
The retro-commissioning measures included tuning of the Scotch-marine steam boiler.
The lighting upgrade included replacing candelabra bulbs
in the first floor main lobby with new 5-watt LED bulbs.
The operation of the heating system controller was
