• Emergency Power Fuel Systems for High Rise Technical Facilities

Urban High-Rise Building Fuel Systems

“Massive structural beams that functioned as a sort of bridge to hold up the 47-story skyscraper known as 7 World Trade Center were compromised in a disastrous blaze fed by diesel fuel, leading to the building's collapse on Sept. 11. (NY Times 02MARCH02)

The dramatic events of that day have brought renewed attention to safety in buildings. The use of diesel fuel in buildings for emergency power and boiler operations is a critical component of building safety. Sound mechanical engineering design and advanced control technologies can be applied to significantly improve current practices.

Design Considerations

The design of emergency power diesel fuel systems for high rise technical facilities is particularly challenging. These challenges are being presented with increased frequency as buildings in urban areas become more technical with a greater need for reliable power sources. Buildings of this type would include hospitals, research facilities, emergency service operations, financial operations, telecom facilities, and corporate facilities with significant computing.

The challenges stem from the highly constrained system layouts which result in separate locations for important fuel system functions. Fuel storage is typically in the basement, fuel delivery areas are at grade, and emergency generators may be on the building roof. Diesel fuel must be safely transferred through the building with fail-safe containment and overfill protection. Information on system status must be shared at the points of use and integrated with the Building Management System (BMS).
