1. Baseline Facility Description

1.1 General Information

The Norfolk Country Correctional Center (NCCC) is located in Dedham, MA and opened in 1993. The campus consists of two (2) buildings – a 140,000 square foot main building with 502 beds and a 12,000 square foot Dedham Alternative Center (DAC). Additionally, there is a 2,500 square foot vehicle maintenance building adjacent to the DAC. NCCC is owned by the Commonwealth of Massachusetts and operated by the Norfolk County Sheriff’s Office. The main building consists of four (4) pods connected to the central unit. There is a control center and two levels of cells at each pod. The central unit is single story and consists of a kitchen, laundry room, administrative spaces, mechanical/back of house areas, and a gym. The gym is now being used to house additional inmates. The main building is currently over occupied and there are plans to add an additional building, potentially housing 50 inmates. There are approximately 600 inmates and 100 staff members on campus.

Figure 1.1 - Campus Layout

1.2 HVAC Systems

The main building consists of four integrated “pods” connected to the central unit. One (1) air-conditioning unit (ACU) serves each of the four pods (ACU-1 through ACU-4). There are four (4) additional ACUs (ACU-5 through ACU-8) serving administrative and office spaces in the central unit. The kitchen, laundry room, and gym are served by four (4) different Heating and Ventilation (HV) units (HV-1 through HV-4). Separate computer room air-conditioning (CRAC) systems serve the computer/IT rooms, which require cooling year round.

The DAC is served by one (1) ACU (ACU-9). The vehicle maintenance building is served by various unit heaters.

B1502090.000 2 | 7

Heating, cooling, and ventilation at the main building pods are provided by four (4) 6,700 to 12,000 CFM constant volume (CV) ACUs. Each unit consists of an outside air intake and filter, one (1) return air fan and relief air section, hot water heating coil, chilled water cooling coil, and one (1) supply fan. The hot water heating coil provides heat for hot deck operation during the winter. The chilled water cooling coil provides cooling for cold deck operation during the summer months.

ACU-5 through ACU-8

Heating, cooling, and ventilation at the main building central unit are provided by four (4) 9,500 to 11,600 CFM variable air volume (VAV) ACUs. Each unit consists of an outside air intake and filter, one (1) return air fan and relief air section, hot water heating coil, chilled water cooling coil, and one (1) supply fan. The supply fan and return fan are equipped with variable frequency drives (VFDs) that modulate the fan speed to maintain duct static pressure.

HV-1 through HV-4 – Main Building

Heating and ventilation in the main building kitchen and laundry spaces are provided by HV-1, HV-2, and HV-3.

These three (3) units are constant volume and consist of an outside air intake and filter, hot water heating coil, and supply fan.

Heating, cooling, and ventilation in the main building gym are provided by HV-4. The gym is currently being used to house approximately 70 inmates. HV-4 is consists of an outside air intake and filter, hot water heating coil, chilled water cooling coil, and a supply fan. Note that the cooling coil was added after the original construction.

AHU-1, AHU-2 and Fan Coil Units – DAC

Ventilation at the DAC is provided by two (2) constant volume air handling units (AHUs). The units consists of an outside air intake and filter, hot water heating coil, chilled water cooling coil, and supply fan. The ventilation air is delivered downstream to the corridors and fan coil units (FCUs) serving various cells and administrative spaces.

Each fan coil unit is equipped with a hot water heating coil and chilled water cooling coil.

All air handling systems are listed in Table 1.1 below:

Hot water at the DAC is circulated by two (2) 3 HP pumps (P-9A, P-9B). These pumps provide hot water to the fin tube radiators, air conditioning units, and fan coil units in the DAC. The pumps are constant volume and are energized 24/7 throughout the heating season. Pump operation is lead/lag with a manual rotation cycle to equalize run time.

There are two (2) 2 HP pumps (P-7A, P-7B) that provide hot water to the vehicle maintenance unit heaters. The pumps are constant volume and are energized 24/7 throughout the heating season. Pump operation is lead/lag with a manual rotation cycle to equalize run time.

This system is located on the second floor and consists of two (2) 300 MBH Raypack units with a 350 gallon horizontal storage tank. There are two (2) sets of paired circulation pumps; this is, one set for circulation between the heaters and storage tank, and the second set for system circulation. The system serves lavatories, showers, and one (1) commercial washing machine.

1.4 Lighting and Lighting Controls System

1.4.1 Main Building

Lighting within the central unit corridors primarily consists of 1’ x 1’ 135W metal halide fixtures. During the walkthrough, it was noted that every alternate fixture was on. Lighting within the pod corridors consists of T8 fluorescent fixtures. Lighting within the cells primarily consists of T8 fluorescent fixtures. Directly outside each cell, is a 9W compact fluorescent lamp. There are 10 high bay 250W metal halide fixtures in each of the pods. During the walkthrough, it was noted that only four (4) of the metal halide lamps were energized. There are additional metal halide fixtures in the gym.

1.4.2 DAC

Lighting with the corridors consists of 4’ T8 fluorescent fixtures with two (2) lamps per fixture. There are four (4) high bay metal halide lamps in the lobby. Each cell consists of one (1) 4’ T8 fluorescent fixture with two (2) lamps per fixture.
