Community Resilience: Reliable Back- Up Power
Community Resiliency re·sil·ience ri ˈ zily ə ns/ noun noun: resilience; plural noun: resiliences 1. the ability of a substance or object to spring back into shape; elasticity. "nylon is excellent in wearability and resilience" 2. the capacity to recover quickly from difficulties; toughness. "the often remarkable resilience of so many British institutions"
USGBC Community Resiliency Priority Better implement strategies to mitigate the effect of disasters Plan and prepare for inevitable events that will come Leverage our knowledge, expertise, tools and resources to rebound smarter, stronger and greener Work with policy makers and community stakeholders to advance programs and policies that allow cities and counties to: ________________________________________
Super Storm Sandy: How Well Were We Prepared?
850 miles in diameter 8,100,000 number of homes that lost power in 17 states Death Toll approximately 125 $25 billion in lost business
Making the City of New York (or any other city; or community) More Resilient
NYC Building Resiliency Task Force – About the Task Force USGBC NY Chapter (Urban Green Council) lead the study More than 200 volunteers, 45 meetings, 5000 hrs, five (5) months Leading experts in their fields Real estate owners, property managers, architects, engineers, contractors, utility representatives, city officials, code consultants, cost estimators and attorneys
NYC Building Resiliency Task Force – Areas of Focus Stronger Buildings Backup Power Essential Safety Better Planning
Considerations in Choosing a Backup Power System Major considerations in choosing a backup power system: The reliability of energy source (solar, natural gas). The method of distribution within the building; prioritize critical loads. There is also an additional consideration that goes beyond engineering solutions: Maximize the resiliency of the primary power source ; constructed/locate it to provide reliable backup for the duration of grid failure; above flood stage.
Maximize Resiliency of Primary Backup Power Source Many undamaged buildings in New York City could not be occupied because electrical service panels and/or emergency generators were located in basements that flooded during the storm surge of Sandy.
Considerations in Choosing a Backup Power System Choose Reliable Backup Power (proven technology). Make Effective Use of Cogeneration, CHP & Solar Power During Blackouts (long term grid failures) Prioritize Needs (establish Essential Safety power requirements; identify Critical Loads) Add Permanent Hookups for Temporary Generators & Boilers (Community; Military) AND
Solar arrays and battery backups can also be used for Essential Safety systems Maintain Lighting for Emergency Exits and Paths In Multistory or Multi-Occupancy Buildings keep Stairwells and Hallways Lit
Solar arrays and battery backups can also be used for Essential Safety systems Provide Power to Water Sources not Able to Provide Water by Gravity.
Maintain Power to Essential Safety Systems Keep Gas Stations Open!! Avoid This with This
Proven Technologies: Distributed Generation (DG) Options Combined Heat and Power (CHP) Cogeneration Bio Mass / Bio Gas Steam and Gas Turbines Reciprocating Gas Engines Fuel Cells Microturbines
Proven Technologies: Microturbines
Solar Electrical Backup for Disasters? Not as Easy as You Think! USGBC Gateway Chapter Roundtable Discussion: Reliability of Solar Applications Participants included: Rep from Urban Green (NY USGBC), electrical contractors; energy consultants; reps from Solar industry (installers & suppliers) discussed: Use of Solar applications during extended power outages How do you design a solar system that could be used when not connected to the grid? What are the barriers? Cost? Technology? Political (codes, zoning)
Solar Electrical Backup for Disasters? Not as Easy as You Think! A sensible approach to emergency home backup power considers: Conserve energy; FIRST become energy efficient before deciding on back up power source Identify critical loads; install a sub-panel Install a backup transfer switch Consider installing a reliable generator; propane/natural gas. Then consider a grid tied solar energy system with battery backup
A Solar Array with Battery Backup; Picture of the Future? You Decide!
