[Bldg-rate] Advanced Buildings Core Performance Guide - Steam Boilers

[Robby Oylear]

Hello all,

 

Does anyone have any experience specifying high efficiency steam boilers
to meet the Advanced Building Core Performance Guide requirements?  Table
2.9.4 lists Steam Boilers at a minimum efficiency of 89% Et.  

 

>From what I've been able to gather, high efficiency steam boilers
typically max out at 83% Ec/AFUE.  Also, in speaking with local
manufacturer's representatives, they have never seen a steam boiler
appliance achieve this level of efficiency.  Is this a mistake?  If not,
does anyone know of a product that can meet this efficiency level?

 

Any help would be appreciated.

 

Thanks,
