D. Energy Baseline Assessment

D.1. INTRODUCTION

Erie International Airport is a publicly owned, primary commercial service airport that serves the aviation needs of Erie County, PA and its surrounding areas. As part of the Master Plan Update, McFarland Johnson performed an Energy Baseline assessment of the existing Passenger Terminal Building, the U.S. Customs and Border Control Building, the Airfield Maintenance and Fire Station Building and the Electrical Vault.

The passenger terminal building is the primary transition point from surface to air transportation for the airport. The original building was constructed circa 1956 and there have been several additions and renovation projects since. At its current configuration the terminal building occupies approximately 47,600 ft2. It is a steel frame, concrete block and face brick construction building with primarily double pane windows and skylights and a flat EPDM, gravel ballast roof.

The U.S. Customs and Border Control Building is an approximately 2,200 ft2 masonry / face brick construction building, with double pane windows and a flat EPDM roof. It was constructed in 1991.

The Airfield Maintenance and Fire Station Building is a 16,500 ft2 building. The building is a steel structure and concrete block with a brick facade and a flat built-up roof construction. The original portion was constructed at the same time that the passenger terminal building was built, in 1956, and has since had two additions added to it. A three-vehicle bay addition was constructed in 1988 on the south end of the building to accommodate the Airport’s ARFF vehicles, and two vehicle bays were constructed on the north end of the building for housing maintenance equipment.

The Airport is currently supplied water by the City of Erie Water Authority. A six-inch diameter water line serves the terminal complex from a water main running along West 12th Street. The passenger terminal complex is served by a six-inch diameter sanitary sewer line connected to the city’s trunk line. Natural gas is supplied to the terminal building by National Fuel Gas; a natural gas line runs from West 12th Street to the meter room on the basement floor of the terminal. GPU supplies electric power to the airport via above-ground power lines running from West 12th Street to Grant Avenue, then underground to the weather bureau, terminal building, and the remaining areas on the Airport.

D.2. PASSENGER TERMINAL BUILDING

D.2.1. Electrical Systems Description

Most of the lighting within the terminal has been upgraded to energy efficient T8 and compact fluorescent. There are still some incandescent lamps installed in downlights (café) and T12 linear

Master Plan Update

Appendix D D-2

fluorescent lamps being used in some areas in the front and back-of-house spaces (kitchen, baggage handling, airline supply spaces, offices, stairwells, cove lights behind ticketing, linear fixtures above the drop ceiling outside passenger screening). T5 fixtures have been installed in the ceiling in the area after passenger screening.

The basement lighting is a mix of T12 and T8 lamp linear fixtures (4’ and 8’ lengths) and ceramic light bases with compact fluorescent and LED bulbs installed in them. Second floor lighting is a mix of T8 and T12 recessed troffers with acrylic lenses. All lighting is controlled with manual switching except for the two restrooms in the secure side of the terminal. These lights are controlled with motion sensors w/timers. Exterior lighting is accomplished with a mix of metal halide downlights, surface mounted metal halide, and pole mounted metal halide and high pressure sodium. There are no exterior LED light fixtures.

Exit signage throughout the terminal is LED. Some of the fixtures have halogen emergency light heads installed on them, some have LED heads. Not all exit signs have emergency lighting installed. Battery tests indicated that not all of the exit signs have batteries that will operate during a power outage. Not all exit signs have battery back-up. Emergency lighting is accomplished with stand-alone emergency units and emergency ballasts installed in recessed fixtures. Emergency lighting and exit signage is powered from a Life Safety power panel which is fed from a back-up generator.

D.2.2. Mechanical Systems Description

The basement level of the terminal houses the terminal’s HVAC controls, telephone, and electrical equipment. The heat for the passenger terminal building is provided by a combination of low pressure steam boiler (Weil-McLain Model 88) and one hot water boiler (Weil-McLain Model Ultra 310). Both boilers use natural gas as the primary energy source. An third, older boiler (Weil-McLain Model LGB-9) has been abandoned in place.

The energy management system consists of a combination of electric controls (FAA offices) and pneumatic controls. The air compressor for the pneumatic controls as well as the electric controls terminal are located in the basement mechanical room. There is a wide assortment of thermostats throughout the facility characteristic of the era that they were installed, ranging from programmable thermostats to temperature sensors and traditional mercury type thermostats.

The main floor of the terminal building is served by a number of roof mounted units and is supplemented in select areas by unit heaters, cabinet unit heaters, air curtains, low intensity gas fired infrared heaters, unit ventilators and thru the window packaged air conditioning units.

The roof top units (RTU) serving the original 1956 portion of the building are providing heat by means of steam coils. Several roof top units have been added as part of addition/renovation projects. Heat from these units is provided either through hot water heating coils or natural gas furnaces. All roof top units provide cooling via packed direct expansion cooling coils. Most of the RTUs have far exceeded their useful life expectancy and should be scheduled for replacement with newer more efficient units.

Master Plan Update

Appendix D D-3

There are several, natural gas fired, domestic water heaters spread out throughout the terminal building to serve the facility’s domestic hot water needs. Public bathrooms have sensor type faucets on the lavatories and sensor flush valves on toilets and urinals.

General exhaust is provided through a number of roof exhaust fans. The Control Tower staircase is pressurized by multiple fans which are part of the smoke control system and are activated through the fire alarm panel.

The restaurant kitchen is served by a commercial range hood. There are several air curtains at the passenger departure/arrival gates intended to reduce energy loss through the open doors during these times that passengers are boarding or exiting the aircrafts. All of the air curtains are either out of order or have been disabled for various reasons.

The boiler and natural gas meters are both located on the basement level of the complex. The fire pump room and associated fire sprinkler risers and air compressor are also located in the basement in their own separate fire pump/sprinkler riser room adjacent to the mechanical room.

D.2.3. Recommendations

In order to conserve energy, it is recommended that all light fixtures utilizing incandescent, T-12, and T-8 lamps be replaced with energy efficient LED light fixtures. LED lighting utilizes approximately 20% the energy of the existing light fixtures and will provide noticeable savings to the airport. Exterior lighting on the apron and in the parking lot can also be changed out to LED light fixtures to provide additional savings.

Install low flow aerators on all lavatory faucets. A faucet aerator can be simply screwed onto the faucet head. Because the aerator limits the water flow through the faucet, water use is reduced by an average of 50% as compared to a faucet without an aerator.

Master Plan Update

Appendix D D-6

In interviewing facility personnel, it was discovered that due to maintenance issues a number of steam traps get stuck either in the open or the closed position. This results in either condensate backing up when the trap is stuck closed, therefore inhibiting the transfer of latent heat, or steam blowing through the trap when it's stuck open, leading to heating issues and waste of energy. A stuck or failed open steam trap can also cause issues with the remainder of the steam traps in the system as it may pressurize the condensate return line, therefore preventing condensate from the other traps from draining properly. Facility personnel also mentioned that whenever any major maintenance is needed the work is contracted to an outside firm or contractor. Regular equipment maintenance has a significant effect on both life expectancy and maintaining peak efficiency of equipment. It is suggested that a regular maintenance schedule is implemented and that maintenance personnel is trained in the required maintenance tasks.

The building automation system (BAS) consists of multiple iterations of various manufacturers, some parts of it original to the building. As a result, the airport is far from realizing the full potential energy savings that a properly implemented control system would offer the capability for. A complete replacement of the energy management system could prove very costly. Factoring in the age of most of the air handling equipment, that would also need to be replaced or upgraded, this type of upgrade could only be viable as part of a capital project.

D.3. U.S. CUSTOMS AND BORDER CONTROL BUILDING


The Custom’s building light fixtures are T12, recessed light fixtures (2x4 and 2x2), T-12 surface wraparound (bathrooms), with a few metal halide recessed downlights. Light fixtures are all manual control with single pole light switches.

Exit signs are old lamp style fixtures with no battery back-up. Emergency lighting is accomplished with stand-alone lighting units and battery tests indicate that these fixtures will operate during a power outage.


The building is conditioned by a pair of gas fired RTUs and miscellaneous electric terminal units, and through the window AS units. The two RTUs are controlled by programmable wall mounted thermostats.

Domestic hot water is generated by a Bradford White Model MI40T6FBN, 40 gallon, 40,000 btu/hr natural gas fired water heater. There are manual flush valves for toilets and urinals. The lavatory faucets are in fair shape and do not appear to be the low flow type.

On the building exterior it was observed that the west and south exposure window caulking has disintegrated. There are also signs of water leakage within exterior block walls, possibly from water pooling on the roof.

Master Plan Update

Appendix D D-7


The existing RTUs are past their useful life expectancy. It is recommended that funds are appropriated for the replacement of the units. Though operations and maintenance costs will be reduced, there is not a significant payback from energy savings to justify the replacement of the units before they are rendered inoperable. Replacement decision should be based on facility importance and the potential of having no heat in the building during the cold winter months if the units fail.

Replace existing lavatory faucets and shower heads with low flow fixtures to conserve water and energy. Typical payback for this type of replacement is less than a year, depending on use time of the plumbing fixtures. This is a relatively low cost measure that can be easily implemented.

It is recommended that the existing fluorescent and metal halide light fixtures be replaced with energy efficient LED fixtures. It is also recommended that automatic lighting controls be added to the offices and bathrooms. The existing exit signage shall also be replaced with LED type exit signage with battery backup.

D.4. AIRFIELD MAINTENANCE AND FIRE STATION BUILDING


The Airfield Maintenance and Fire Station Building has T8 recessed troffers in the office area and T12 linear fixtures (4’ and 8’ lengths) in the truck and maintenance bays. The old salt storage area, which is now used as a two-bay truck area has 400W metal halide light fixtures. 250W and 400W high pressure sodium fixtures are installed on the exterior of the building. Interior lighting is controlled with manual switches. Exterior lighting is controlled by photocell.

Exit signage throughout the AARF/Maintenance Garage is LED with battery back-up. Battery tests indicate that these fixtures will operate during a power outage. Emergency lighting is accomplished with standalone emergency fixtures with a mix of halogen and LED lamping. Battery testing indicated that some of these fixtures will not operate during a power outage. A 400kw generator was installed in 2008 to supply power for life safety.


The Airfield Maintenance and Fire Station Building is primarily served by multiple low intensity, gas-fired infrared heaters which are typical for this type of building use. The office area and employee is served by a packaged gas-fired RTU. The RTU and infrared heaters are controlled by programmable wall mounted thermostats.

There is a partial sprinkler system serving the mezzanine area in the building but there were no alarm devices observed, which is inconsistent with NFPA standards and International Fire Code.

There is an air compressor for used for maintenance on the stored vehicles and an emergency generator.

Master Plan Update

Appendix D D-8

The vehicle storage bays are also served by multiple exhaust fans controlled by wall mounted switches. The fans are intended to exhaust heat in the warm summer months. No carbon monoxide (CO) or nitrogen oxides (NOx) sensors were observed which are typically utilized for exhausting vehicle storage bays when potentially hazardous concentrations of CO and/or NOx are detected.

A 40 gallon, 40,000 btu/hr, natural gas fired water heater (Whirlpool Model M40T91-403) provides the domestic hot water for the facility.


It is recommended that the existing T12 and T8 light fixtures be replaced with energy efficient LED fixtures. It is also recommended that the existing metal halide and high pressure sodium light fixtures be replaced with LED type fixtures. Automatic lighting control should be added to bathrooms and break rooms to turn lighting off when the rooms are not occupied.

Emergency lighting throughout the building should be verified to be operational and non-working units should be replaced to ensure operation during times of need.

It is recommended that a CO / NOx detection system is provided for the facility and tied to the existing exhaust fans. The existing exhaust fan capacity should be reviewed for adequacy of exhaust volume capabilities.

D.5. ELECTRICAL VAULT


The vault houses all of the constant current regulators (CCR’s) for the airfield lighting. Airfield lighting has been upgraded in certain areas and is original in other areas. Runway 6/24 has all new incandescent lighting, new cable, new conduit, and new transformers and cans. Runway 2/20 is all original equipment. Taxiway ‘A’ edge lighting is LED for the extended part of the taxiway. This was done in 2012-2013. The balance of taxiway A’s lighting is original (transformers, cans, cable, conduit). Taxiway ‘C’ lighting between Taxiway ‘A’ and Runway 2/20 is new LED and transformer utilizing original cable and cans. Taxiway ‘D’ lighting between Runway 6/24 and Runway 2/20 is new LED and transformer utilizing original cable and cans. Signage on the airside is currently being changed out to LED. Twenty-three of the existing signs have yet to be changed out to LED. Existing cabling is being utilized except those signs associated with the runway. The cable feeding these signs was changed out during the runway extension project. The light fixtures in the vault building utilize T8 lamps.


N/A


The airport is currently undertaking the replacement of some of the signage light fixtures to energy efficient LED type fixtures. It is recommended that the airport continue to replace
