Raytheon Labs21 Pilot
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.
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.
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
Also, we will discuss the implementation of EnergyStar® equipment
within the offices and labs as well as the implementation of sleep
mode computer equipment.
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
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.
