Hello All: 

 

-  Major objective: Goal is to save a charitable organization here in the N.E. some of their high utility costs at an adult services/senior care center that functions as  heartbeat of this major neighborhood. 

 

- Building Particulars:  Fully Functioning basement, three-story brick and steel.  Very well built c. 1939-1940. 

  Audited  building envelope.

  Required measures are being planned for implementation. 

  New operable double-sash thermally-insulated windows throughout within last 6 months. 

  New #4 oil-fueled boiler c. 1993 fully insulated. 

 

-  Methodology: calculate and/or modeling waste heat from three computer labs with two servers, extensive offices with p.c.s, faxes and floor model heavy-  duty photocopiers on two additional floors, full hot-meal (lunch) cooking kitchen with several double-sided freezers, refrigerators and icemakers.  

 

-  Process: 

   audited throughout, 

   prepared electrical appliance  database of manufacturer's MSDS wattages.

      

-  Goal: Channel all waste heat into recovery heat to work with the 8 air handlers by: 

     1. changing AHU cav to vav  

     2. adding electronic controls to monitor heat recovery and 8 AHU.  

     3. monitor end-goal performance of AHUs. 

     4. realize immediate utility bill cost savings.   

 

Working with current E-Quest. 

 

Thank you for your help.
