Office

= Introduction = High-rise offices are probably the most numerous of all of DDCs portfolio. These offices will range from partial buildings to full buildings. Twenty-six of these offices are located within the five SIRR flood zones. This constitutes the second largest group after firehouses.

= Special Resilience Considerations = With the majority of high-rise offices well above flood level, floodproofing is not as high a priority as other building types with the exception of elevators.

Like other commercial buildings with flat roofs, careful consideration should be given to securing loose materials on the exterior of the building to ensure that they do not become missiles. One example of an exterior architectural element that should be secured for hurricane force wind is rooftop pavers - typical of igh rises. Special care should be taken to anchor any exterior mechanical or service equipment that is a component of communications or building services that are essential to the building's functioning.

**Power Outages** Utility systems design should be designed to accommodate power failure events that occur in any weather condition. Solar PV could run generators and emergency lighting, as well as just be a "green" source of energy throughout the year. The aftermath of Hurricane Sandy saw lower Manhattan streets filled with mobile generators with wires snaking across sidewalks. The addition of quick connects would address this issue. Lastly, CHP would be in line with the dialog now being had in NYC and the surrounding areas about setting up micro grids.

Other Upgrades
In addition to disaster resilience, attention should also be paid to everyday use. For this reason, the use of low- or no-VOC materials, water remediation, and operable windows (especially pertinent when 90% of our time is spent indoors at work).
