Energy Efficiency

Succeeding in our corporate sustainability goals includes improving and reducing energy use at our facilities and in our operations. We’re leveraging the same data-driven, systems-focused process MITRE uses to solve the world’s greatest problems to tackle energy efficiency challenges.

At our campus headquarters and across our IT infrastructure, office equipment, and electronics, we’re developing and delivering on the energy efficiency and conservation solutions we need to reduce emissions, lower costs, and succeed in improving our operational sustainability. 

Green Sites

MITRE operates across two primary campuses and numerous satellite offices in the United States and around the world. For the purposes of our internal sustainability goals, energy efficiency and facility sustainability at these sites are important aspects of the decision-making process—whether at a MITRE campus or a satellite office.

To meet internal standards for energy efficiency and sustainable operations, MITRE combines new construction, upgrades to existing facilities, and a “green” lease strategy for satellite offices with an eye toward reducing our impact on the environment and maximizing our contribution to the public good.

Our campuses also feature several energy conservation improvements that balance sustainability with operational performance, including:

  • State-of-the-art Johnson Controls Building Automation Systems, which monitor and control the internal environment of MITRE facilities and maximize heating and cooling efficiency.
  • White roofs, which reflect heat and limit the need for energy-intensive cooling in the summer months.
  • Motion-sensor enabled lighting, which automatically turns off office lights when unoccupied.

Building Design

Our MITRE Center was certified as one of the first LEED Silvercertified buildings in Massachusetts shortly after opening its doors in 2004. Located in Bedford, the 96,000squarefoot facility features a stateoftheart heating and cooling system designed to meet the climate control needs of our built footprint with a much lower energy impact. A solar array is also located onsite to assist in meeting the MITRE Center’s energy needs.The MITRE Center also incorporates a wide range of lighting efficiency measures inside and out. Smart lighting fixtures adjust to respond to natural daylight levelsmade even more efficient by light shelves incorporated on exteriors that direct additional daylight into spaces. Lighting efficiency extends beyond daylight hours: at night, the MITRE Center’s exterior lighting incorporates fixtures and planning designed to limit light pollution.

MITRE 4, located in McLean, is the first facility built with MITRE’s new workplace standards in mind. The 340,000squarefoot, LEED Goldcertified facility combines highrise office space with research and development labs and incorporates sustainability across its design.The facility combines systemslevel efficiency with design features that improve employees’ ability to engage with sustainable features day to day and at an individual level. Combined with lowflow plumbing, efficient light fixtures, improved irrigation, and a building skin system, MITRE 4’s highefficiency central mechanical plant reduces operations resource use across the board. A stormwater cistern on the roof provides a sustainable source for water retention and reuse on campus grounds.For employees, MITRE 4 also offers landscaped roof terraces and facilities for alternative fuel vehicleselements that encourage and incentivize more sustainable practices in daily working life.

Located on the east side of MITRE’s Bedford campus, the Laboratory Building is a LEED Silvercertified facility covering 105,000 square feetincluding 30,000 square feet of open laboratory space. The Laboratory’s design incorporates natural light across both office and laboratory space, alongside energyefficient light fixtures to reduce energy use during the day and maximize the impact of lighting solutions. Watersaving fixtures and a stateoftheart heating and cooling system round out a holistic approach to reducing the Laboratory’s emissions footprint overall. Opened in 2012, the Laboratory was constructed to replace the 1950sera “E” building as part of the campus master plan to improve operational standards at MITRE’s Bedford site. Studies of energy use at the Laboratory show a 40% improvement over the building it replaces.

Capital Improvements

M Building’s original, energyintensive pneumatic HVAC controls system dated back to the facility’s original 1991 construction. By removing the old system and replacing it with a direct digital control system in 2018, MITRE heats and cools the building more efficiently and reliablyand saves on energy costs.

By replacing campus parking lot lights with new highefficiency LED fixtures in 2017, the Bedford facilities teamreduced annual campus electricity use by 114,000 kilowatthours, saving $15,000 per year in energy and maintenance costs and improving lighting levels across all lots

After a strategic review of the McLean campus, MITRE chose to expand the campus cafeteria instead of building a new one. The original space, which could no longer accommodate the growing number of employees on campus, was reconfigured and expanded in 2017 to better serve MITRE’s workforce while limiting the environmental impact that would have come from new construction.

Green Leasing

MITRE leases space at about 30 satellite offices across the United States and around the world. To ensure MITRE’s satellite offices meet efficiency and sustainability standards that are comparable to our campuses in Bedford and McLean, the MITRE Corporate Real Estate team weighs these factors when it comes time to sign or renew leases

Energy Audit

MITRE released an RFP for a Level II ASHRAE energy audit of the McLean and Bedford campuses. Information gathered in this energy audit will create a concisereport to describe possible Energy Efficiency Measures (EEMs) including potential capital upgrades.

Green IT

Implementing a more efficient, environmentally-friendly IT infrastructure is a priority for assessing MITRE’s current operations and planning for our future needs. While green alternatives that don’t sacrifice IT performance often have higher initial costs, MITRE believes the long-term savings—and the promise of a more positive impact on the environment—are worth the investment.


To better measure the energy impact of our IT infrastructure, MITRE’s corporate IT group benchmarks total data center energy use—including equipment, heating and cooling use, and supporting electrical systems—against peer companies. MITRE is taking the same data-driven approach to maximizing IT efficiency and energy efficiency that we do with sponsor projects, and applying that data to initiatives designed to improve IT’s carbon footprint.
