Background

In 2009, the City of El Paso’s Council adopted a Sustainability Plan which includes a goal to reduce the organization’s energy use by 30% by 2014. To meet this goal and revitalize city infrastructure, El Paso initiated an Energy Savings Performance Contract in 2007. Building on the momentum of the first four phases of work, which included 44 building upgrades, including renewable energy installations, HVAC upgrades, lighting retrofits, and a facility management system, the El Paso International Airport (EPIA) was an obvious next step.

Background

El Paso International Airport (EPIA) provides first-class passenger and air cargo service to the three-state and two nation region, including West Texas, Southern New Mexico and Northern Mexico. Encompassing nearly 7,000 acres of land, the airport plays a vital role in the regional transportation system, not only for aviation and airline passenger travel, but also for industrial, commercial, and cargo activity. The EPIA buildings that will be addressed include the Main Terminal, Customs & Maintenance, Warehouse I-III, and Butterfield Trail Golf Course Building.

Solutions

The EPIA had outdated HVAC equipment that increased hot and cold spots and was not very efficient or comfortable. Although the EPIA does have lots of natural light, that came with issues too. The glare and heat from the windows made areas uncomfortable during hot summer months. The EPIA project will include lighting retrofits and controls, solar window film, central plant upgrades, and installation of a facility-wide energy management system.

Solutions

The airport main terminal lighting upgrades include retrofits to more efficient lamps and ballasts; wired and wireless lighting controls; a web-based control system; and daylighting controls throughout interior spaces. HVAC improvements address the airport’s aging central plant and include three new efficient chillers and pumps; four new efficient boilers and pumps; heat exchanger upgrades; and refurbishment of the existing cooling tower. The facility energy management system will replace all pneumatic valves and controllers with direct digital controls that optimize HVAC systems and consolidate three outdated controls systems into one central dashboard.

The estimated costs and energy impacts from the planned capital investment projects are:

Other Benefits

The goals of the EPIA upgrades are to improve indoor environments for travelers and employees, improve reliability of lighting systems, run HVAC system more efficiently, and to save on utilities and operations and maintenance costs. This project is the fifth phase in the City’s Energy Savings Performance Contract with Johnson Controls. The annual energy savings from all five phases are projected to be over $2.8 million with an additional $600,000 in utility rebates from El Paso Electric.
