FW: Richard Barnett 9 East 71st Street Contact Info

Hi Stanley it was a pleasure speaking with you toda at 9 east 71st street thanks for ou time and understanding of what it takes to operate this property my office Please inform Steve Hanson of what we discussed and try to stress that August is not t ie time to o t e cooling tower and chiller installation project. looking forward to working with you .Thanks Richard Barnett.

Rich, thank you for the tour of the residence. As we discussed my recommendation for the solution to the air conditioning issues in the master bedroom and gym would be to install a seperate system for both these areas as follows:

Install a 10 ton Mitsubishi R series condensing unit on the roof of the premises. The unit is extremly quiet and has a total weight of approx. 700 lbs. The system will also contain a Branch Controller which would be located within the residence. The air handler for the master bedroom would be located in the ceiling of the electrical closet located adjacent to the Master Bedroom. A special flowbar diffuser would be installed above the existing crown moulding and the ceiling. The diffuser would be used for both suppy and return. A seperate air handler would be installed in the closet of the gym and connected to the existing grill. I am refering to the grill to the left when you are facing both closets.

At this time you are setting the chilled water discarge at 42 degrees so that the master bedroom and gym can achieve lower room temperatures than the rest of the house. By having seperate units for the critical areas of the bedroom and gym the discharge temperature of the chilled water can be raised some and it would not be necessary to reheat the air in the other rooms before it is discharged into the rooms.

I am suggesting a ten ton condenser so there will be left over capacity after the installation of the bedroom air handler and gym airhandler for future needs. You should leave the existing bedroom and gym supply air intact. Close the dampers and use the Mitsubishi system as the primary cooling or heating for those two rooms. The Mitsubishi system is capable of heating one room and cooling the other at the same time. It is also the most energy efficient product on the market. Almost every brownstone air conditioning/heating system being installed today is variable volume refrigerant systems such as Mitsubishi.

A budget price for our work excluding power wiring, general contracting work and protection would be approximatly 80 to 90 thousand dollars. A firm proposal could be prepared if you would like to pursue this further.

You had mentioned that there is a planned HVAC project for August 3 this summer and the residence would not have any air conditioning for a couple of weeks. I would strongly suggest that you delay the project so that it could be done in the fall when the house would not affected by the heat of summer. The finishes and fumishings should not be subjected to high temperatures and humidity.

If there is any additional information needed, please feel free to contact me.

Respectfully submitted, Stanley Berger
