LEED® CONCEPTS IN AVIATION DESIGN The benefits of going green Leed® Concepts Building on the cornerstone of sound engineering principles, the U.S. Green Building Council (USGBC) has developed a strenuous certification program that applies specific concepts for environmentally responsible and sustainable design. Integrated Approach by Gerald Williams, P.E., LEED®AP and Karen Stelling, P.E., LEED®AP The USGBC’s Leadership in Energy and Environmental Design, or LEED®, system integrates project teams of architects, engineers, owners, contractors and operators. These teams support a holistic approach to developing high-performance and environmentally responsive building systems. LEED design improves quality of life, as most of our time is spent indoors. It also provides positive financial impacts. Multi-layered Savings LEED design produces savings through the use of modeling, building orientation and design features that optimize energy and utility system sizing and minimize waste and environmental impact. While LEED design saves money on energy and utility systems, even greater savings, often overlooked, can be found in personnel and profitability measures. Studies demonstrate improved productivity, retention and reduced absenteeism among those working in buildings incorporating LEED concepts. Stores using LEED concepts (good natural lighting, improved indoor air quality, and independent temperature and lighting controls) have also reported greater sales than traditional buildings. As a cost-cutting measure, a major retailer installed skylights at one of its “Eco Stores.” Sales numbers from that store showed sales per square foot in the daylit half of the store were significantly higher than sales in other departments. Wal-Mart has since implemented similar green design elements in other stores. 6 ( Burns & McDonnell Wide Application Burns & McDonnell professionals have applied LEED concepts to a wide range of buildings for government and private clients. For example, Burns & McDonnell was responsible for National Oceanographic and Atmospheric Administration (NOAA) and Alaska’s first LEED-certified building — a new Tsunami Warning Center. With more than 24 LEED Accredited Professionals (APs), Burns & McDonnell is committed to the LEED design process and the benefits that it brings to our clients. Our engineers continually find ways to apply LEED principles to a variety of projects, including aviation design. LEED for Aviation Providing good indoor air quality at airport terminals is a challenging task. Terminals are typically surrounded by air pollution-generating jet engines, bus engines, auto traffic, smoking zones and cooking facilities. By modeling prevailing winds, strategically locating outside air intakes and using high-efficiency and charcoal filters to capture particulate contaminants, fumes and odors, the harmful effects of pollution near airports can be significantly reduced. Natural light and exterior views create a more pleasing indoor environment. However, where security concerns prevent the use of windows, such as Transportation Security Administration (TSA) screening rooms, Burns & McDonnell architects and engineers have creatively met the challenge. Their use of translucent walls allows light to pass, but prevents direct line of sight. The result is an enhanced work environment that does not compromise security. Healthier Buildings, Healthier Balance Sheet These are just a few of the benefits of the integrated LEED design approach. High-efficiency HVAC and lighting systems reduce energy use and save on operating costs for the life of the facility. Careful material selection helps ensure that contaminants like VOCs, formaldehydes and other harmful chemicals are not introduced. The balanced use of materials with high recycled content and diversion of recyclable or reusable construction waste from landfills is a cost-effective reflection of stewardship. Building for the Future LEED APs guide the integrated team from project concept to completion. They ensure the use of proven “green” concepts to create cost-effective, sustainable buildings. As part of clients’ teams, Burns & McDonnell applies green-building design techniques to create energy-efficient and environmentally friendly facilities that will serve the needs of several generations. Energy Management with LEED By Laura Thompson, P.E., and Ed Mardiat How can air por ts trim operating costs, protect the environment and provide better ser vice? There is a way A Midwestern regional airport is taking management of its energy and operating costs to a higher level. Like many airports across the country, its facilities were built in the 1940s and 1950s, when efficiency considerations were not a factor. Additions over the years considered comfort and efficiency in terms of transportation, but didn’t include energy efficiency in the design equation. Advances in technology have created systems and equipment that are able to provide optimal comfort and operation — while achieving greater energy efficiency than the systems currently installed. These system improvements will enhance lighting, air quality, heating, air conditioning and power supply to the airport facilities — and optimize airport operations and maintenance. Burns & McDonnell will provide turnkey services to design, install and commission the improvements. As a result of these changes, Burns & McDonnell will also provide a guarantee that the energy and operational savings will entirely fund the improvements — and produce an additional cash flow for the airport annually. Burns & McDonnell is developing an energy management program to upgrade much of the equipment and energyusing systems at this airport’s facilities, incorporating LEED design components in the improvements. The program will provide a strategic capital planning tool for future maintenance and construction. 2005 ( Aviation Special Report 7
