300 Madison Avenue


Designed by world-renowned architect Skidmore, Owings & Merrill, 300 Madison Avenue is nothing short of a modern architectural masterpiece. At 38 floors, 1.2 million square feet, and just one block from Grand Central Terminal, 300 Madison is a testament to the ambition of New York City. Upon its completion, owner and developer, Brookefield Properties, had one more wish: energy efficiency. Contracted to fulfill this desire, TEC Systems knew any building management system would require similar creativity and precision, and provided just the solution.

Integrating two floors of mechanical equipment with ancillary building automation components strategically installed facility wide, TEC Systems produced an all-inclusive, energy-efficient masterpiece. Utilizing Honeywell’s EXCEL® 5000 Building Management System to automate and synchronize system functionality, TEC Systems provided 300 Madison with multiple state-of-the-art heating and cooling systems for maximum savings.


    Heating: 300 Madison’s heat supply operates differently than conventional heat mechanisms. Hot water is created by shell-and-tube heat exchangers, while a pressure-reducing station produces low-pressure steam. In addition, hot water and steam also serve heating coils, located in various heating and air-handling units, such as the entrance heater.
    Cooling: TEC exchanged vertical all-air variable air-conditioners with supply-air systems outfitted with cooling coils to create dynamic airflow throughout several office spaces. In addition, fan systems were outfitted to be capable of varying designed airflow by utilizing variable speed-fan motor drives.
