Provided Mechanical and Electrical Engineering services for the replacement of the existing Heating, Ventilation and Air Conditioning (HVAC) system serving the historic mansion and related administration building.

The new HVAC system consisted of central heating and cooling plants with several floor and ceiling mounted air handling units located throughout the mansion and the administration building. The cooling plant included modular chillers, chilled water pumps and related underground/aboveground chilled water piping. The heating pant included gas (propane) fired heating water boilers, heating water pumps and related heating water piping.

Reportedly, the mansion was constructed more than two hundred (200) years ago and lack of the building envelope insulation created a challenge to maintain the proper temperature and humidity conditions inside the mansion which houses various historic art effects. The air handling units serving the mansion were equipped with humidifiers to address the proper humidity levels in the mansion during the heating season.

The physical restrictions imposed by the historic nature of the building also were challenging in routing ductwork/piping and selections of the air handling units, air distribution devices, etc. and needed to be closely coordinated with the historic committee representatives.

The increase in the electrical loads of the new HVAC equipment required the incoming electric service to the mansion and administration building to be upgraded. The revised electrical loads for the mansion and administration building which consisted of the new HVAC loads and other existing loads were provided to the utility company. The routing of extensive underground primary electric service was coordinated with the historic committee representative and the utility company to avoid possible historic sites.   e
