- Installed additional building rooftop solar thermal hot water system.
- Installed two additional building rooftop solar photovoltaic systems.
- Awarded LEED Platinum certification for a newly constructed office building.
- Awarded LEED Gold certification for a newly constructed Data Center.
- Initiated a preferred parking program for qualifying eco-commuters. Employees with energy-efficient and earth-friendly vehicles, participants in the vanpool program, and active carpoolers have access to premium parking and electric vehicle charging stations.
- Installed numerous environmentally friendly and energy-efficient technologies in new and existing buildings.
In addition to employing various sustainability measures at its headquarters, SAS takes pride in supporting environmental education and awareness efforts. In 2011, SAS supported numerous environmental speaking engagements, visits to the SAS solar farms, companywide Earth Day celebrations, featured articles posted on the internal green website, and published white papers and webcasts. By engaging with customers, employees, industry leaders and world leaders, SAS seeks to extend the reach of its sustainability initiatives.
SAS did not receive any sanctions or fines in 2011 for noncompliance with environmental laws and regulations in the United States.
SAS continues to deliver on a commitment to customers, employees, and the environment with Building C at SAS world headquarters in Cary, NC. With minimal impact to the surrounding natural environment, this showcase of sustainability and style includes an office tower, a socially conscious café and the SAS Executive Briefing Center, which is used by customers, partners and the community.
SAS strives to be a sustainability leader by investing in innovative technologies that help minimize the environmental impacts of its business. This commitment led the design and construction decisions for Building C, resulting in LEED certification at the Platinum level by the US Green Building Council (USGBC). Built with minimal environmental impact, this “green building” was designed to consume 40 percent less energy and 50 percent less water by integrating numerous, highly efficient technologies and sustainable features, including:
- Rainwater is captured from roof drains and stored in two 20,000 gallon underground cisterns for non-potable water use in bathrooms.
- High-efficiency plumbing and electronically activated fixtures reduce employee water consumption and the amount leaving the building for wastewater treatment – resulting in 63 percent savings compared to EPA standards.
- A 655,000 gallon retention pond collects stormwater runoff to minimize erosion impact and pollution of local water sources; it also provides landscape irrigation. Building C’s design will reduce landscaping irrigation demand by at least 75 percent.
- 405 solar photovoltaic panels feed power to the building for lighting and building systems.
- A solar thermal system uses the sun’s energy to preheat the hot water supply for the cafeteria.
- To decrease the load on heating and cooling systems, fresh air is pre-conditioned with heat and humidity from the building’s exhaust air.
- With highly efficient motors to reduce energy usage, regenerative drive elevators generate electricity during their descent to help power lighting, computers and other electrical equipment.
- With high-performance spandrel glazing backed with semi-rigid insulation, exterior glass reflects a substantial amount of heat.
- A one-acre living sedum green roof minimizes stormwater runoff; it also increases the building’s insulation, absorbs CO2 and provides a natural habitat for wildlife. White reflective membranes on rooftops reflect the sun’s energy and keep the roof cool. The reflective nature of the membrane helps increase the efficiency for the solar photovoltaic systems. Green roofs significantly minimize the heat island effect – the thermal increase between developed and undeveloped areas that can cause smog and increase ambient temperatures.
- Thermal slab floor cooling uses water cooled in off-peak hours by building chillers to help maximize air conditioning efficiencies.
- Radiant floor heating is used in the atrium to maintain floor-level heat for greater occupant comfort and minimize heat loss through the roof.
- Highly efficient HVAC systems integrate economizers, enthalpy wheels, variable-speed drives, and various heat recovery systems to increase energy savings.
- Energy is saved by using T5 fluorescent and LED lighting fixtures along with individual lighting controls, motion sensors and automatic timers.
- Night light pollution is reduced by using full cut-off exterior lights and an automated system to turn off all interior lights at night.
- Designated preferred parking spaces and electric car charging stations are available for eco-commuters. Bike racks and showers encourage employees to bike to work.
- The cafeteria provides a low-carbon menu and serves locally grown vegetables from the one-acre organic culinary farm at SAS headquarters.
- The dining area’s food waste is composted and used by SAS landscapers to enrich soil throughout the SAS campus – waste vegetable oil is recycled and converted into biodiesel fuel.
- 82 percent of construction waste was diverted from the landfill.
- The Building C site preserved almost 1 million square feet of open space to help maintain local ecosystems.
- The landscape planting for the project has been developed with native plants that are predominantly medium- to highly drought tolerant.
- All trees removed from site were reused for accent walls and furniture inside the building, donated to Warmth for Wake (a seasonal energy assistance outreach program) or chipped for landscape in plant beds.
- Artisans crafted the site’s timber into the building’s indoor furniture and wall panels.
- All office furniture purchases were Green Guard Certified, but most of the building’s furniture came from employees’ previous offices, a reuse practice that minimizes waste to landfills. In addition, the majority of the new furniture was manufactured locally in North Carolina. 69 percent of wood products used in doors, casework and blocking are certified by the Forest Stewardship Council (FSC), ensuring that sustainable harvesting practices were met.
- 27 percent of materials purchased for this project came from within 500 miles of the project.
- 23 percent of materials purchased had recycled content.
- All carpet installed was Carpet and Rug Institute’s Green Label Plus certified and all composite woods were free of urea-formaldehyde, which ensured the indoor air was as free from unnecessary odors and chemicals as possible.
- CO2 sensors and demand-controlled ventilation supply outside air into the building as needed, which helps save energy while also providing optimal air quality for employees and guests.
- During construction, the contractor implemented an Indoor Air Quality Plan that addressed HVAC protection, source control, pathway interruption, housekeeping and scheduling issues.
In addition to Building C’s achievements, the newest SAS Data Center received LEED Gold Certification. SAS is also embracing LEED guidelines for remodeling and retrofitting existing buildings. In 2011, SAS registered five existing buildings for future LEED certification consideration.

Energy and Emissions
Finding ways to conserve energy and implement more energy-efficient initiatives are ongoing objectives for SAS. This year, SAS installed numerous environmentally friendly and energy-efficient technologies in new and existing buildings. The new Data Center has allowed SAS to consolidate IT equipment from other locations and retire antiquated equipment.
In 2011, SAS generated 3,833 megawatt hours of renewably sourced solar power from rooftop and ground-mounted solar installations. Three new rooftop systems were activated in 2011:
- A 169 kW photovoltaic system was installed on the office roof of Building R and will provide approximately 208,000 kWh annually for use within the building.
- A 74 kW photovoltaic system was installed on the office tower roof at Building C and will provide approximately 100,000 kWh annually for use within the building.
- Another building rooftop solar thermal hot water system was installed. Solar water heat is used on sunny days to help supply the estimated 3,000 gallons of hot water used primarily in the kitchen.
SAS continues to implement LEED guidelines and best practices in the pursuit of formal certifications for new and existing buildings, as well as leased and owned office renovations. SAS has expanded use of energy-efficient lighting technologies such as LED, fluorescent and metal halides. SAS installed two elevators with regenerative drive technologies. The elevators generate electricity on descent for use within the building. The thermal slab floor cooling system installed last year uses water cooled in off-peak hours by building chillers to help maximize air conditioning efficiencies. Radiant floor heating is used in a building atrium to maintain floor-level heat for greater occupant comfort and minimize heat loss through the roof. Highly efficient HVAC systems in several buildings integrate economizers, enthalpy wheels, variable speed drives and various heat-recovery systems to increase energy savings.

Increased energy use was due primarily to the Data Center expansion. Over the past decade, the challenge of delivering timely information to support enterprise analytics has increased exponentially. The deployment of additional computing and storage solutions, combined with IT globalization at corporate headquarters, has increased demand for energy and data center space. Existing facilities were reaching capacity and could not be efficiently expanded to maintain the high level of support expected by SAS’ customers. The solution was to design and construct a dedicated computing facility, emphasizing efficiency, flexibility and sustainability.
This past year, the new Data Center achieved an average Power Usage Effectiveness (PUE) of 1.35.
The data center industry uses the PUE calculation as a measure of efficiency. A PUE of 2.0 means that for every watt of IT power consumed, an additional watt is consumed to cool and distribute power in support of the IT equipment. A data center is more efficient when it uses less energy to run the facility than to power the IT equipment. So, the closer it gets to a PUE of 1.0, the more efficient it is.
Managing Greenhouse Gas EmissionsSAS completed the Carbon Disclosure Project (CDP) Supply Chain questionnaire related to greenhouse gas (GHG) emissions inventory and related climate change management in response to customer requests. SAS' overall score was 71 out of 100, up from 65 last year and well above the average of 51.
