systems; An emergency exhaust and make-up supply air

system is required. The exhaust/make-up system is required

to provide an emergency air flow rate that is equal to 100

times the square root of the refrigerant mass. This

emergency ventilation system is activated by an automated

leak detection and alarm system, and is separate from any

other ventilation system in the building. The detection

system shall have audible and visual alarms which shall be

tied to the building fire alarm systems. Alarms shall be

provided at each entrance to the refrigeration room and a

manual purge valve shall be provided on the exterior of the

building for fire department use. The refrigerant shall

automatically be purged if the room temperature exceeds

safe limits.

monoxide detection system.

III. Recommendations.

A. Building Heating Plant.

1. We have investigated two possible heating fuels for this building,

LP gas (propane), and No. 2 fuel oil. Based on the current and

projected costs of these two fuels, we recommend using No. 2 fuel

oil. From the October 2008, Vermont Fuel Price Report (published

monthly by the Vermont Department of Public Service), the cost of

No. 2 fuel oil is $34.15 per million BTU, while the cost of LP gas

is $42.68 per million BTU. (LP gas is currently the most costly

heating fuel.)

2. The proposed heating plant will consist of multiple modular boilers

to maximize the efficiency of operation. This system will provide

heat for the following.

Hot water coils for the heating and ventilation air handling

units. This includes the main unit for the ice rink area,

which has dehumidification capacity, and smaller units

serving the other occupied areas. To reduce the freeze risk

for the heating hot water loop serving these units, which

use outside ventilation air, the heating loop shall be a

glycol/water solution.

Terminal heating units such as fin tube radiation and unit

heaters which serve unoccupied areas without ventilation

air requirements.

Indirect fired domestic water heaters.

3. Heating load calculations will be made once the facility

dimensions and constructions means are defined. Given the total

49



heating load, the number and size of modular boilers will be

determined. The goal is provide multiple boilers for back-up

capacity and efficient heating at various part-load demands.

4. We recommend that the heating plant be served by an above

ground fuel oil tank. Tank size to be determined once the total

heating capacity is determined. The above ground storage tank will

include leak containment and will limit the potential for future

environmental contamination. A final choice of fuel tanks will be

discussed with potential fuel suppliers to determine if discounts are

available for larger deliveries.

B. HVAC System of the Ice Rink/Arena Area.

1. The ventilation system will provide the air flow rates as described

in the ventilation requirements section above. Most importantly the

humidity levels in the arena area must be maintained low enough

to prevent surface condensation, fogging, and dripping within the

structure. The air distribution ductwork system will be designed to

avoid air movement over the ice surface.

2. To accomplish this level of humidity control and maintain the

proper ventilation rates, an industrial grade desiccant dehumidifier

is recommended. This will permit year round operation of the

facility by properly eliminating humidity generated within this

space from the ice surface, the occupants, and the resurfacing

equipment, as well as the humidity introduced by the outside

ventilation air.

3. The system described above will include a modular air handling

unit equipped with fans, heating coil, desiccant dehumidifier and

reactivation heater, and if desired, capacity for a future cooling

coil. This system will be capable of maintaining the arena at 70 deg

F and 40% relative humidity during spectator attended events. For

practice events without spectators and night setback conditions, the

temperature set point can be lower (55 deg F, adjustable). The

glycol heating loop heated by the central heating plant will serve

both the main heating coil and the dehumidifier’s reactivation

section.

C. HVAC System for the Team Rooms.

1. We recommend that the heating and ventilation air provided to the

team rooms (locker/changing rooms) be provided by the arena air

handling unit with dehumidification capacity. This will avoid

introducing humid air to the skating rink from high skater traffic

flow between the rink and the team rooms.

2. Local duct mounted heating coils will used for each of the team

rooms to maintain the room temperature set point throughout the

50



occupied period of these rooms (given rink temperature will vary

with the spectator schedule).

D. HVAC System for the Front Support Areas.

1. The heating and ventilation air for the remaining portions of the

building will be provided by an energy recovery ventilation unit,

which will reduce the heating load of the outside ventilation air by

was much as two-thirds. Local duct mounted heating coils will be

provided to permit individual room control. These coils will be

supported by the glycol heating loop from the central heating plant.

E. HVAC System for the Refrigeration Room.

1. As previously described in the ventilation requirements section;

upon detection of a leak in this area, audio visual alarms will be

activated, the general building fire alarm system shall be activated

and emergency exhaust and make-up supply air fans will be

activated to purge the room. The refrigeration room doors shall be

automatically closed upon activation of the refrigerant detection

system or the fire alarm system as audio visual alarms on the

exterior side of the doors are automatically activated. The outside

location of the emergency exhaust air outlet and the make-up air

Inlet will be sited to insure no cross contamination occurs with

other ventilation system inlets/outlets. A manual fire department

external refrigeration purge system shall be provided. The

refrigerant shall automatically be purged if the room temperature

exceeds safe limits.

2. The refrigeration room will include general ventilation capacity

which will provide the normal ventilation rate as described above,

to maintain room air quality and to remove excess heat from the

room.

3. This room shall be heated by a unit heater supported by the glycol

heating loop from the central heating plant.

F. HVAC System for the Ice Resurfacer Machine Room.

1. As described in the ventilation requirements section above, this

room will be protected by a carbon monoxide detection system and

accompanying automated ventilation system. This system will

include a carbon monoxide sensor and alarm system. Upon

detection of an unsafe level of carbon monoxide within the

resurfacer room, the general building emergency alarm system

shall be activated, the room’s internal overhead door will close

(separating the resurfacer from the main arena), and exhaust air

and make-up supply air fans will be activated. A self contained

humidistat shall be utilized and connected to a local vent to

eliminate excessive moisture build-up at the ice-melt-pit. 51



2. This room shall be heated by a unit heater supported by the glycol

heating loop from the central heating plant.

E. Ice Resurfacer Machine Ice Pit System.

1. The ice resurfacer machines conduct resurfacing operations up to

15 times daily. With each operation, they are cutting/dumping

approximately 200 gallons of ice, with a daily total reaching 3,000

gallons at peak. The ice surfacer machines will dump their ice

shavings into a common pit in the Resurfacer Room. The pit will

have a snow melt system to insure the ice will have melted in the

pit before the next ice resurfacing operation. There are two options

56



for melting the ice internally. The first is to utilize a heating coil in

the pit. The heating source for this first option will be a condenser

glycol/water solution from the ice making refrigeration system.

The second option is to use a shower down system. This second

option utilizes a series of shower head to spray hot water onto the

ice shavings in the pit. A 4” drain from the pit to an exterior storm

drainage system will be required. Drains for each end of the arena

will also connect to this drain system.

F. Roof Drainage System.

1. At this point, no roof drains and interior storm drainage piping is

expected. If any roof drains are needed, there will a minimum of

two roof drains as described in the storm drainage code

requirements above. The piping will be sized in accordance with

the 2003 IPC.

FIRE PROTECTION CODE ABSTRACT & RECOMMENDATIONS


2003 International Building Code.

NFPA 13 Standard for Installation of Sprinkler Systems, 2002 Edition.

II. Requirements.

A. Building is classified as a Group A-4 assembly area by the building code,

and an automatic sprinkler system is required.

B. A wet-pipe sprinkler system is required.

C. NFPA 13 Classification – The facility minus the mechanical and

refrigeration rooms is Light Hazard, sprinkler design capacity is 0.10

GPM/square foot over 1,500 square feet area (150 GPM). Light hazard

flow duration is 30 minutes. The mechanical (boiler room) and the

refrigeration room are Ordinary Hazard, Group 1, sprinkler design capacity

is 0.15 GPM/square foot, with flow duration of 60 minutes. As long as

mechanical room and refrigeration room are separated by location or fire

rated walls, we need only consider the square footage of the larger

refrigeration room (estimated at 900 square feet). We compare the

demands for the two different hazard areas.

Light Hazard: 1,500 SF x 0.1 GPM/SF x 1.2 sprinkler head

correction = 180 GPM x 30 minutes duration x 1.1 storage

tank safety factor = 5,940 gallons of water storage.

Ordinary Hazard, Group 1: 900 SF x 0.15 GPM/SF x 1.2

sprinkler head correction = 162 GPM x 60 minutes duration

57



x 1.1 storage tank safety factor = 10,560 gallons of water

storage.

The flow rate and water storage capacity is chosen from the

more demanding requirements from the two areas. The

higher flow rate is 180 GPM (from the Light Hazard area)

and the higher water storage capacity is the 10,560 gallons

(from the Ordinary Hazard, Group 1 area).

Calculation assumptions: Roof slope does not exceed 4 in

12, as a higher slope roof requires a sprinkler flow rate

increase. Generally a hose connection flow rate is not

required in areas without fire hydrants. This assumption

will need to be verified with the local fire department and

the VT Division of Fire Safety.

D. Sprinkler system to be hydraulically designed by a NICET III sprinkler

designer or fire protection engineer.

E. Backflow prevention device is required on the sprinkler service, which

meets the standards of AWWA Manual M-14.

F. Sprinkler valves, alarms, and devices to be supervised by the building fire

alarm system. The alarm system shall meet the standards of NFPA 72, The

National Fire Alarm Code.

G. An accessible fire department connection is required for connection to the

fire suppression system.


A. We recommend installation of a wet pipe automated sprinkler system for

this facility. A hydraulic design for the water supply requirements will be

required. Based on preliminary estimates, a minimum supply rate of 180

GPM for 60 minutes will be required. Given that this site will be utilizing

well water, a fire service water storage capacity of 10,560 gallons and a

fire pump rated for 180 GPM at the calculated pressure capacity, will be

needed. A diesel powered, vertical turbine fire pump is required to draw

water from a buried water storage tank. The pump will be located in the

heated pump house above the water storage tank.

II. Requirements.

A. Building Mechanical Systems (Section 803, of the 2005 Vermont

Guidelines for Energy Efficient Commercial Construction).

1. Electric resistance heating is prohibited.

2. Calculations of heating and cooling loads. Trane Trace 700

software will be used to calculate the heating and cooling loads of

the facility. This software applies the procedures described in the

ASHRAE Fundamentals Handbook. These calculations shall

determine the size of the heating, ventilation, and air conditioning

(HVAC) systems and equipment.

3. Equipment efficiency. The equipment efficiencies shall achieve as

a minimum the standards of the equipment efficiencies tables in

the referenced energy codes. This includes all boilers and the

terminal heating units and the ice making refrigeration system.

4. HVAC controls.

Controls for each of the heating zones in the facility will be

capable of seven day programming which will allow night

setback of the temperature set point. Each heating zone will

have its own temperature sensor.

Controls of the ice rink area air handling unit will include

temperature and humidity sensing for control of the heating

and dehumidification operations. The controls for this unit

will allow event scheduling to vary heating and ventilation

for different programmed events.

The central heating boiler system will include outdoor air

reset to vary the temperature of the main glycol heating

loop in response to outdoor air temperature to achieve

operational savings.

5. Ventilation shall be provided in accordance with the 2003 IMC as
