FAA "SAVES" WITH "GREEN" ACQUISITION INNOVATION

# S-4-07
(graphic provided of "FAA SAVES" FLYER)
FAA not only saves on office supplies but goes "green" in its acquisition process. Is your agency looking for savings and sustainability too? Check out how FAA did it.
In 2006 the Federal Aviation Administration (FAA) awarded a new office supply contract to Office Depot that provides products at considerable cost savings.
The 5-6 million dollars per year contract is part of the FAA Strategic Sourcing for the Acquisition of Various Equipment and Supplies (SAVES) program. The mandatory nationwide contract is expected to save 30% annually or more in office supplies.
The contract language developed and implemented serves as a template for other agencies (including GSA) contemplating a similar cost-savings office supply contract. A required “green” office products component was included that allows employees access to over 1,000 items serving to fulfill FAA’s RCRA, previous EO 13101, “Greening the Government Through Waste Prevention, Recycling, and Federal Acquisition”, and now EO 13423, “Strengthening Federal Environmental, Energy, and Transportation Management” requirements.
Environmentally preferable purchases (EPP) are tracked on a monthly basis enabling a baseline to measure progress.

"SPECIAL ACHIEVEMENT"
EPA is using this project to demonstrate that sustainable design and LID can be utilized in high profile, urban sites that must pass through rigorous aesthetic design reviews. (www.epa.gov)
The U.S. Environmental Protection Agency (EPA) and U.S. General Services Administration (GSA) are demonstrating low impact development (LID) and sustainable stormwater management practices in a landscape renovation project at EPA’s Federal Triangle Headquarters in Washington, DC. Initiated in May 2001, this multi-year project involves three landscape retrofit projects at EPA’s Federal Triangle Headquarters complex.
The Federal Triangle complex’s building roofs, sidewalks, courtyards, and parking areas make the area approximately 95 percent impervious to rain. Through this green infrastructure project, however, EPA will reduce the adverse impacts of stormwater flows from the 25-acre site. The Agency also hopes to reduce the peak volume and pollutant load of its stormwater runoff and serve as a model for future LID projects nationwide.
Completed in December 2006, the 8,600-square-foot Ariel Rios South Courtyard (see diagram), at the southeast corner of Federal Triangle, is the largest phase of the demonstration project. Showcasing the sustainable strategy of addressing targeted watershed goals and objectives by using LID stormwater management techniques, the courtyard demonstrates a wide range of techniques in its 6,400 square feet of LID landscaping. Particularly, it includes two bioretention cells that provide more than 400 cubic feet of stormwater storage volume and a 1,128-gallon cistern to collect stormwater that is recycled for irrigation of the site.
Based on rainfall in 2006, it is estimated that the LID components divert approximately 70 percent of the rainwater that falls on the courtyard throughout the year from the storm sewer. It is also estimated that reusing the rainwater collected in the cistern for irrigation will, in turn, reduce the need for potable water by approximately 30 percent.
The most publicly visible phase of the project is a retrofit of the landscaping that lies at the south end of the Federal Triangle complex, on Constitution Avenue. Completed in April 2005, the area includes 1,264 square feet of bioretention cells, which provide another 400 cubic feet of stormwater storage volume. The site demonstrates how disconnection, storage, evaporation, and sustainable plantings, combined with high-efficiency irrigation systems, can be used on a large scale. EPA seized the opportunity to promote LID and proper stormwater management to passersby in this high foot traffic area and is awaiting final approval to integrate educational signage and materials on this site in Fall 2007.
The construction contract for the final phase of the project—an installation of six cisterns, with a total capacity of 6,000 gallons, in the parking garage under the EPA West Building—is to be awarded in Summer 2007. The cisterns are designed to collect runoff from the Federal Triangle complex roofs and reuse it for irrigation of a portion of the Constitution Avenue site.
Results for the entire project will not be available until the third phase of the project is complete. Using preliminary estimates from the courtyard as a guide, there is no doubt that the actual project results will indicate a substantial reduction in harmful stormwater runoff and potable water use.

EPA’s Region 8 Office, Denver, Colorado - A Sustainable Showcase

# S-16-07

In January 2007, the U.S. Environmental Protection Agency (EPA) began occupying its new Region 8 Office (see photo), located in historic, downtown Denver, Colorado. This 418,000-gross-square-foot (GSF) facility showcases an array of water and energy efficient features and sustainable design elements and serves as an example of the Agency’s commitment to designing, constructing, and operating highly sustainable buildings. Designed to achieve both the ENERGY STAR building label and U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Gold certification, the facility is expected to yield and annual energy savings of more than 35 percent over the American Society of Heating, Refrigeration and Air-conditioning Engineers, Inc. (ASHRAE) Standard 90.1-1999, saving a total of nearly 12,000 British thermal units (Btu) per GSF.
The Region 8 office is the culmination of two and a half years of careful planning and construction, including a comprehensive, two-stage design competition conducted by EPA and the General Services Administration, who will lease the building to EPA for 10 years. Acknowledging the importance of smart planning early in the process, the agencies worked with competing design teams to develop a facility that incorporates the best in overall design, work environment, performance, value, and security, while also reducing the building’s environmental impact, particularly on the surrounding Rocky Mountain region.

Taking an innovative and holistic approach, the winning design team integrated Denver’s cool climate and abundant sunshine to save energy and improve building performance.
High-efficiency, building-wide systems, such as under-floor air delivery and air-side economizers save approximately 9,600 Btu/GSF/year and also improve indoor air quality. The building incorporates extensive daylighting, which exposes 85 percent of the building to natural light. Additional sustainable features include the use of water-efficient plumbing fixtures that are expected to reduce the facility’s water consumption by 36 percent; construction materials that are made from renewable sources; and low volatile organic compound interior adhesives, paints, sealants, and caulk that will improve indoor air quality. Additionally, 80 percent of the building’s construction wastes were recycled rather than disposed of in a landfill.

Of the building’s most unique and impressive attributes is its 19,200-square-foot, three-level “green roof” –the first of its kind in Denver.
The rooftop features a 3”-4” organic soil layer and drought-resistant plants that help to reduce rooftop and building temperatures, filter air pollution, and reduce stormwater runoff by 27 percent. A 48-panel photovoltaic array, also on the roof, will contribute 10 kilowatts of green power, or nearly 14,000 kilowatt hours per year, in addition to the 4.7 million kilowatt hours of renewable energy certificates EPA purchases annually for the office.

Byron G. Rogers Federal Courthouse Renovation:

"Paving the Way for High Performance Building and Sustainable Building Practices"

# S-8-07

Public Buildings Service Rocky Mountain Region
(Byron G. Rogers Federal Courthouse Renovation)
"SPECIAL ACHIEVEMENT"
Renovating the Byron G. Rogers U.S. Courthouse (BRCH) building allowed GSA to save natural resources while making the surrounding environment healthier to tenants and the community at large. The key to the success of this project was that the project team used an integrated sustainable design approach throughout the design and construction process. They shared a vision of remodeling this building to earn a LEED-EB Gold Rating from the U.S. Green Building Council (USGBC) while recognizing the social advantage of recycling a historically significant building expected to qualify for the National Register of Historic Places. It is our responsibility as a Federal agency to invest ourselves in actions such as this project as to positively impact society and allowing the vision to manifest itself into reality.
The Byron Rogers U.S. Courthouse (BRCH) renovation project included careful integration of sustainable design features. This project was one of the first 50 projects designated as a pilot project for the U.S. Green Building Council’s (USGBC) LEED for Existing Buildings program. The Courthouse renovation project earned an official LEED-EB Pilot Gold Rating from the USGBC in 2006. This project is the first GSA-owned LEED Gold rated building and the first GSA LEED-EB rated building.
The BRCH consists of courtroom and office space on five levels and two levels of underground parking. Constructed in 1965 and designed by James Sudler Associates and Fisher and Davis, the Courthouse is considered to be a “Formalist masterpiece” by local historians. Over the past 40 years, very little has been done to upgrade the building’s systems, functions or appearance. In 2002, GSA initiated a four-year design and construction process to modernize this tired, but sturdy structure. Working with Bennett Wagner & Grody Architects, a comprehensive interior renovation was planned and executed. Results of the effort include a new public entry and lobby; complete mechanical, electrical, security and technology upgrades; full asbestos abatement; ADA compliance; renovation of offices and public spaces; courtroom upgrades; rejuvenated exterior façade and site. The courthouse is believed to have historic significance, and it is projected that once it meets the 50-year ago requirement, it will qualify for the National Register of Historic Places.
This Courthouse exemplifies what might be considered the most important sustainable strategy a project could incorporate – building reuse. It also is a national example of how agencies can meet goals outlined in Executive Order 13423: Strengthening Federal Environmental, Energy, and Transportation Management, specifically, the goal that, “new construction and major renovation of agency buildings comply with the Guiding Principles for Federal Leadership in High Performance and Sustainable Buildings set forth in the Federal Leadership in High Performance and Sustainable Buildings Memorandum of Understanding (2006), and (ii) 15 percent of the existing Federal capital asset building inventory of the agency as of the end of fiscal year 2015 incorporates the sustainable practices in the Guiding Principles.”
The building shell and structure were reused, in addition to key interior materials in the building’s lobbies and courtrooms. Program verification began in January 2002, and the building was occupied by February 2006. The project included demolition, asbestos abatement, and lead paint removal followed by renovation.

"... it demonstrates that building performance can be maximized without sacrificing beautiful architectural design or healthy and happy workforce considerations at a cost per square foot that rivals conventional building construction costs..."
In October 2006 the General Services Administration (GSA) delivered a $307 Million new home for the US Census Bureau. This magnificent state-of-the-art 1.4 million-square-foot building (along with 3,100 parking spaces in two garages) houses 6,000 employees and contains offices, an auditorium, training and conference areas, cafeterias, cafes, credit union, fitness center, library, and support space.
The GSA project team embraced the philosophy of sustainable design from the project’s inception, and directed fellow team members to incorporate LEED® Silver level elements and sustainable design principles:


  • optimizing site potential,

  • minimizing non-renewable energy consumption,

  • use of environmentally preferable products,

  • protecting and conserving water,

  • enhancing indoor environmental quality, and

  • optimizing operational and maintenance practices

into every square inch of the US Census Bureau Headquarters’ complex.


Using a sustainable design philosophy encouraged decisions at each phase of the design process to reduce negative impacts on the environment and the health of the occupants, without compromising the bottom line. This integrated, holistic approach positively impacted the team’s consideration of all phases of the complex’s life-cycle, from design to construction to commissioning to operation.
This collaborative, integrated approach resulted in the completion of a complex that is absolutely breathtaking inside and out. Even more relevant, the US Census Bureau Headquarters can serve as a model for future construction projects and substantial renovations because it demonstrates that building performance can be maximized without sacrificing beautiful architectural design or healthy and happy workforce considerations at a cost per square foot that rivals conventional building construction costs – even on a massive scale, such as this 1.4 million-square-foot building – and be built to last 100 years. In addition, after one year, another LEED review will be conducted in order to verify building performance, which is a very innovative feature which may be performed and replicated on other Government projects.
The vision, oversight, and financial commitment for a sustainable facility was initiated and continually supported by the General Services Administration (GSA). GSA collaborated with several other organizations to see this project completed. Skidmore, Owings & Merrill (SOM), the design firm, contributed the initial concepts of siting, design, and sustainable features. The detail for the design was established by HKS, the architect of record. The construction delivery and field implementation was led by Skanska USA.

GSA Mid-Atlantic Regional Energy Program Saves Energy

# S-13-07

Public Buildings Service Mid-Atlantic Region
(photo: The Edward N. Cahn Federal Building and Courthouse in Allentown, Pennsylvania, has experienced a decrease in energy consumption of 21.5% between FY05-06 due the innovative retro-commissioning program.)
The mission of the Mid-Atlantic Regional Energy Team is to continuously reduce energy consumption for the region, focusing on opportunities that are in our control, well leveraged, and are compatible with wise business practices.
As nation’s largest energy consumer, the Federal government establishes policies for improving energy management in an effort to reduce building operations costs, lower emissions that contribute to air pollution and global warming, and conserve resources.
The Public Buildings Service (PBS) strives to operate efficiently and effectively to meet these energy conservation goals which provide the best value for both customer agencies and taxpayers. By reducing energy consumption and expanding the use of renewable energy, GSA is striving nationally to reduce energy usage by 2% per year for the next 10 years for a 20% reduction, using 2003 usage data as a baseline. GSA partners on a customer-by customer basis to provide specific conservation measures in order to meet this goal.
As an overall driving goal, the region’s six field offices were challenged with achieving a 2% reduction in energy consumption over the 6-month period January 2006 - June 2006 (measured against the same 6 month period the previous year). Reviews of building operation plans to determine operational opportunities were conducted that balances consumption reduction without undo impact to our tenants. Particular focus was placed the on region’s highest energy consuming buildings.
The team worked directly with the Mid-Atlantic Region’s Public Buildings Service Field Offices to produce significant reductions in energy consumption at Federal facilities and leases under their charge. Their efforts brought about an 8.3% reduction in energy consumption in fiscal year 2006 as compared to fiscal year 2005. The consumption reduction efforts positioned the Mid-Atlantic Region 5.9% below its fiscal year 2006 energy consumption reduction performance measure target.
The operational conservation efforts exercised by the Mid-Atlantic Regional Energy Team, resulted in significant reductions in energy consumption. This initiative- which struck the balance between energy conservation and maintenance of high-service levels to the customer- is a prime example of employing sensible efficiency procedures in building operations to bring about significant reductions in energy consumption.

National 3D-4D-BIM Program Focuses on Sustainability

# S-11-07

Public Buildings Service Central Office

"... better accuracy, transparency in assumptions, and reliability in estimations of energy performance and major savings through mechanical system optimization have been realized using BIM."
GSA's National 3D-4D-BIM (Building Information Models) Program includes a focus on sustainability. Established in 2003, the Program has been recognized widely by the design and construction industry for its leadership and its mission of promoting value-adding digital visualization, simulation, and optimization technologies to increase quality and efficiency in the delivery and management of GSA’s capital assets.
What are 3D, 4D, and BIM?

3D, 4D, and BIM are innovative technologies that offer virtual design and construction during the planning phase of the project. They represent three separate, but synergistic, ways in which computer technologies can aid GSA to manage its capital assets throughout a project’s lifecycle. 3D geometric models are the geometric representation of building components and typically serve as an aid for visualization. 4D models (3D + time) include information that can inform and analyze project phasing, tenant sequencing, and construction scheduling. Building Information Models (BIMs) include 3D geometric models, with specific information on a wide range of building elements and systems associated with a building (e.g. Spaces, air handling units, and circulation zones) applicable to the full lifecycle of GSA’s facilities.


The Need for Sustainability in GSA Building Performance

GSA Public Building Service (PBS) provides and maintains quality workplaces for over a million Federal agency associates in approximately 8,500 owned or leased buildings across the United States. Through its use and management of these facilities, the Federal Government is the largest consumer of energy in the Nation, resulting in significant opportunities to reduce its resource consumption by incorporating sustainable design methodologies.


Innovation Benefits of BIM-Based Energy Analysis

One critical activity in the building design process is the prediction, analysis, and validation of building energy performance. A BIM-based model enables better, more detailed understanding of building performance (e.g. thermal behaviors of building spaces, thermal properties of walls, daylighting analysis). Once a baseline energy model is established, designers can analyze many more scenarios, as compared to the traditional 2-3 analyses.


To date, better accuracy, transparency in assumptions, and reliability in estimations of energy performance and major savings through mechanical system optimization have been realized using BIM. In one of our pilot projects, a courthouse building was analyzed at a detailed space by space level, while the traditional energy model was only capable to analyze the building using less detailed zones on each floor. The transparency of the modeling process enabled by using BIM allowed the modeling team to uncover several unreasonable assumptions that would not have been caught using the traditional energy model. The BIM-based analysis (with revised assumptions) predicted 30-50% higher energy consumption than the traditional approach, and also resulted in more consistent simulation results.
Replicating GSA Successes with Collaboration and Strategic Adoption of Technologies

To share lessons learned and promote replicability of our successes in the Regions and other organizations, GSA has developed a BIM Guide Series on best practices, a public website (www.gsa.gov/bim) with 14,000 hits and 900 BIM Guide downloads since November 2006, an internal GSA web-based portal, a community of regional BIM Champions, and national contractual language and deliverables.
