! • Preface

This study includes an engineering review of the existing mechanical heating, ventilating, and air­ conditioning systems serving five buildings located on the Western Massachusetts Hospital campus. At least, two HVAC options for each building are presented, keeping in mind the future potential uses of the buildings as expressed by the Massachusetts Department ofPublic Health.

Executive Summary.

Wozny Barbar and Associates (WB&A), partnered with Baker/WohlArchitects (BWA), have been tasked with evaluating the mechanical systems of five buildings located on the Western Massachusetts Hospital campus located at 91 East Mountain Road in Westfield, Massachusetts. The Main Hospital is a 93,000 square foot, three-story building with basement, circa 1910 that serves as a chronic care facility, with the goal to convert back to a medical facility. The unoccupied Quarry Hill dormitory consists of two-stories with basement and may be converted to a Veterans Administration dormitory with treatment, recovery, and outreach program support. The Clark building is two-stories supporting administrative services for the hospital. The Garage is an open floor plan pre-engineered metal building installed on a slab, providing maintenance for campus machinery. Finally, the Storeroom is a two-story warehouse providing storage and , shipping support. For all five buildings, the existing heating equipment consists of gas and/or f:/2 oil-fired boilers serving cast-iron radiators, unit ventilators, and unit heaters and is in average condition. This study describes the existing conditions of the mechanical systems serving each building in more detail below. Two options were considered for each building and the recommended option is discussed in detail further in this report.

Project Justification

Based on the existing equipment age, condition, code shortfalls, and a desire to upgrade the campus services offered, a study to establish a concept and baseline for equipment replacement is warranted. The systems are difficult to work on in making repairs due to the complexity and age of the distribution system, given all the temporary repairs and additiOn$ that have OCC1:11Ted over the years. Problem Statement

The existing mechanical equipment has had the minimal necessary repairs and additio~ over a number of years, with little or no documentation, maKing· further repairs dif~cult and, in some cases unsafe for the staff.

Existing Conditipns

Based on field observations, review of existing documents and discussions with building management staff, WB&A provides descriptions of the existing mechanical services for the five buildings included as pait of this report.

Main Hospital:

Heating is provided for the building by one of two dual-fuel Cleaver Brooks packaged boilers, I . • located in the basement, installed in April, 1988, with input capacity of6,277,000 Btu per hour. The boilers, fired by either natural gas or #2 fuel-oil, produce low-pressure steam.(8-pounds) that is connected to distribution piping serving cast-iron radiators and baseboard located throughout the facility. Condensate returns to a duplex condensate receiver tank where it is pumped to a 1Joiler feed tank for delivery back to the boilers to repeat the process. Each steam heating radiator and baseboard device is controlled by a thermostatic radiator valve.

Three Hurst boilers, installed in 2002, with input capacity of 420,000 Btu per hour, fired by either natural gas or #2 fuel-oil, produce medium-pressure steam (45-pounds) that is connected to distribution piping serving the kitchen and laundry. Condensate returns to a duplex condensate receiver tank where it is pumped to a boiler feed tank fot: delivery back to the :boilers to repeat the process.

Mechanical ventilation of toilet areas is provided by exhaust duct risers up to roof-mounted exhaust fans. Operable windows provide ventilation for the bedrooms.

Numerous packaged terminal air conditioners, located above the windows, provide cooling for selected bedrooms and office spaces. Several split-system air conditioning units, with roof­ mounted condensing un~ts, provide cooling for selected internal spaces.

A 20,000-gallon single-wall underground storage tallk.supplies #2 fuel-oil to the Cleaver Brooks heating boilers. The Hurst boilers are fed from the 3,000-gallon undergroUnd storage tank used to operate the Emergency Power Generators. Main Hospital Cleaver Brooks Boilers Hurst Boilers

Quarry Hill Dormitory:

Heating is provided for the building by an HB Smith packaged steam boiler installed in 1987, installed in the basement, with input capacity of 1,125,000 Btu per hour. The gas-fired boiler produces low-pressure steam that is connected to distribution piping serving cast-iron radiators and baseboard located throughout the building. Condensate returns to a duplex condensate receiver tank where it is pumped back to the boiler to repeat the process. Each steam heating radiator and baseboard device is controlled by a thermostatic radiator valve.

Preferred Solution

For all five buildings, Option 1 is the preferred recommendation for the following reasons:

~ain Hospital: The four-pipe heating and cooling system allows for heating and cooling on demand while providing humidity control. Each patient room is. provided with a thermostatically­ controlled fan-coil unit for ideal space comfort control.

Quarry Hill Dormitory: The hydronic two-pipe system provides good quality heating or cooling while utilizing a single grade-mounted chiller as opposed to several condensing units located around the perimeter of the building. Each dormitory room is provided with a thermostatically­ controlled fail-coil unit for ideal space comfort control.

Clark Building: The hydronic two-pipe system provides good quality heating or cooling while utilizing a single grade-mounted chiller as opposed to several condensing units located around the perimeter of the building. Each office space is provided with a thermostatically-controlled unit ventilator for ideal space comfort control.

Garage: The existing gas-fired Modine unit heaters are in good working order and can continue to remain in service. Adding general ventilation to the open garage area will prove to be an inexpensive improvement.

Store Building: Due to the fact that this building has a large percentage of glazing, utilizing steam in lieu ofhydronic heat is the best solution to guard against damage due to frozen pipes. Concept Design

General diagrams depicting flow diagrams ofproposed four pipe heating and cooling system, two­ pipe manual changeover system, heating-orily distribution system, and steam distribution system, are indicated on sketches attached.
