OVERVIEW OF WHAT WE WILL COVERModern Absorption applied in Cogen or CHP or “CCHP” 

Focus on “Modern Absorption Applications” that yield the following benefits

Lower Operating CostLower Carbon FootprintsResiliency improvementsReduced use of Fossil FuelsSimple “ways to design” CHP

Is My Building a Good Candidate for CHP? 

 

Are average electricity rates more than $.07/ kWh (including generation, transmission and distribution)? 

Is there a need to reduce energy costs or minimize exposure to possible increases in electricity rates? 

Is the building located in a deregulated electricity market?  Is power reliability a concern? Would there be a substantial business, safety, or health impact if 

power went out?   Does the building operate for more than 5,000 hours/year?  Are there thermal loads throughout the year (including steam, hot water, chilled water and hot air)? 

 

 "Yes" answers to any of these questions suggest the building may be a good candidate for CHP.

STORE DESIGN CONSIDERATIONS

All Mechanical equipment on roof ( resiliency ) Gowanus canal “water management” “Beckwith relay” does not allow exporting power Transfer switches allow store to shed non-critical

loads during a “island mode operation” System was “pre-packaged and tested” FAT! FAT Made for a simple start up 24/7/365 monitoring via store BMS and CCHP

suppliers PLCs and internet. Grid independence - run business with or

without grid – product loss mitigation – keep the register ringing – be an asset to the community they serve.

CCHP TURNS ON 2/20/2014 Hi folks, Congratulations to everyone on 2 huge milestones today: we got

National Grid’s sign off and passed ConEdison’s witness test! The generators started up successfully, and we will be working tomorrow to dial in synchronicity on all systems. I appreciate everyone’s hard work to get to this point. Please let me know if you have any questions.

Thanks! J'aime Mitchell, LEED Green Associate Associate Coordinator of Construction | Green Mission Specialist

56,000-square-foot structure is 60 percent more energy efficient than the building code requires. That's right: 60 percent more efficient, making it one of the most energy efficient supermarkets in the nation, Whole Foods says.( source greenbiz.com )
