Raytheon Labs21 Pilot Project

David Gaudet, Raytheon

Abstract:

The Raytheon Labs21 Pilot Project is a 505,000 square-foot communication and air traffic control laboratory dedicated to research, development, and administrative activities in Marlborough, Massachusetts. The facility was built in 1987 and energy efficiency was a key design criterion. Raytheon C3I would like to further evaluate our laboratory energy usage and develop strategies to reduce electricity consumption at this site while not adversely affecting operations. A 73,000 square foot building is being constructed for satellite communications equipment testing. It is being built within the criteria of the LEEDS program and certification is being sought.

Laboratory Baseline and Post-verification Metering:
Along with HVAC systems and lighting, R&D labs for electronic equipment account for the lion's share of energy consumption. Currently, an electrical energy usage reduction campaign is being rolled out. Laboratory Management and staff are supporting this energy usage reduction program. We will present the techniques that are most successful in controlling lab electricity usage. Base line metering data has been obtained for one week of operations for each of the heavy usage labs. The management teams for operations of these labs have been briefed on methods to reduce electricity consumption. The measures are presently in the implementation phase. Post-verification metering will be compared to the baseline to demonstrate results.

Mechanical Systems:
Energy efficiency has been designed into the laboratory's mechanical systems. We will highlight this process and operation, by giving an overview of systems. Specific items to be highlighted are central cooling plant, dedicated built up penthouses with four pipe system, plate and frame heat exchanger free cooling system, energy efficient variable speed drive chillers, demand side ventilation control, energy management system controls, variable speed air-handling system, and on/off scheduling of exhaust fans.

Electrical Systems:
The lighting systems in the laboratory are controlled by a lighting control system with occupant override capabilities. Half-lighting schemes are used as well as day-lighting photocell control in glass-walled lobby areas. The fixtures themselves are T-8 and T-12 systems with electronic ballasts. We have one area that is a pilot for fixtures with on-board occupancy sensors and day-lighting control, being controlled on and off and dimmed through each occupant's computer workstation, which has been used as a model for the SatCom building lighting system.

Also, we will discuss the implementation of EnergyStar® equipment within the offices and labs as well as the implementation of sleep mode computer equipment.

Management Systems:
We will discuss the use of Envinta's One to Five Energy Management tools, Best Practices and Benchmarking tools as well as other resources made available to us through the Labs 21 Tool Kit. We are also retro-commissioning our mechanical and electrical systems, and those results will be reviewed. We are also participating in the Labs 21 Benchmarking program.

Employee Awareness:
An Employee Awareness campaign has been implemented. We use poster programs, employee suggestions, Earth Day campaign, National Energy Awareness month campaign and periodicals to get employees in the energy-conserving mode. Raytheon also has developed "REAP", or Raytheon Energy Action Program, which all of these issues fall under, complete with an identifying logo, see below. Employees can go to a web site on the Company Intranet to learn about the REAP programs. A Labs 21 web page is currently under construction here and will be highlighted in our presentation.

LEEDS Certification for SatCom Building:
The 73,000 square foot testing facility for communications satellite equipment will soon be complete. We will highlight the LEEDS commissioning and certification processes.
