Chapter 1: Sustainable Development – What and Why? Mission Impact Vision for Sustainable Development Sustainable Development at LANL Purpose of the LANL Sustainable Design Guide Organization of the LANL Sustainable Design Guide LANL | Chapter 1 Sustainable Development – What and Why? “It is not what we have that Los Alamos National Laboratory Sustainable Design Guide 1 will make us a great nation; it is the way in which we use it.” – Theodore Roosevelt LANL Mission Impact As the nation increases its emphasis on security, the Los Alamos National Laboratory (LANL) stands as a center of excellence, bringing forth unique facilities and capabili ties on issues of national significance. LANL’s infrastruc ture and most facilities were constructed during a period that extended from 1943 to the early 1960s. These facili ties are now being targeted for replacement. In addition, new mission assignments are demanding state-of-the- art facilities to extend capabilities for the next 50 years. LANL’s population is also aging, creating the need for significant recruitment in response to increasing retire ments. Such factors present LANL with a unique opportunity to form and foster an exceptional work environment that supports its mission and attracts and retains the people most qualified to fulfill that mission. What is an “exceptional work environment?” This work environment includes and must consider the: Individual laboratory and/or office space. Tools and equipment used by an individual and the ease of the human/machine interface. Surrounding structure or building and its created climate. Chapter 1 | Sustainable Development – What and Why? Sustainable development is “…developing the built environment while considering environmental Interstitial or common space that facilitates popula tion massing and encourages cross communication. Transportation (pedestrian and vehicular) options that provide ease of access. Natural environment in which the work environment is established. An exceptional work environment supports and encour ages interconnectedness among these elements con tributing to efficiencies and productivity. The process of Sustainable Development will be a key element to establishing LANL’s exceptional work environment. The sustainable development concept encompasses the materials to build and maintain a building, the energy and water needed to operate the building, and the ability to provide a healthy and productive environment for occupants of the building. Often, sustainable devel opment has been referred to as climate-sensitive design, whole-building design, or high-performance buildings. Much of the original work in this field was done under the auspices of passive solar design – for which LANL was a national and international leader. Los Alamos National Laboratory Sustainable Design Guide 2 responsiveness, resource efficiency, and community sensitivity.” – Sustainable Design Report for the Los Alamos National Laboratory Strategic Computing Complex, LANL document LA-UR-01-5547. LANL Chapter 1 | Sustainable Development – What and Why? Vision for Sustainable Development LANL vision for sustainable design In furthering its commitment to a safe and comfortable working environment that meets its program require ments and is responsive to environmental issues, LANL has established a vision for sustainable development. Sustainable design of LANL facilities is one of the most cost-effective strategies available for ensuring the high level of research output from the Laboratory upon which our nation depends. Buildings in the United States consume 37 percent of the nation’s primary energy. With advanced design strategies, a 50 percent reduction in energy consumption can become the stan dard practice for a new generation of buildings. Leading-edge federal buildings demonstrate that far greater reductions in energy consumption – 50 percent or more – are both possible and cost-effective. Build ings that consume fewer resources to construct and operate will have lower environmental impact than today's conventional buildings. This lower impact leads to less air and water pollution, reduced water consump tion, improved human comfort, and higher creativity, productivity, and job satisfaction for employees. As a leader in sustainable development, Los Alamos National Laboratory commits to employing design and construction approaches that maximize productivity within the built environment, minimize impact to the natural environment, and assure good stewardship of public funds and resources. Los Alamos National Laboratory Sustainable Design Guide 3 “The vision for the physical develop ment of the Laboratory is to create an exceptional work environment that supports the mission, and attracts and LANL – Site and Architectural Design Principles retains the quality personnel needed to meet the mission.” Chapter 1 | Sustainable Development – What and Why? Los Alamos National Laboratory Sustainable Design Guide 4 Project Details: ■ Project funding: GPP ■ Project description: Research and Office Building ■ Size: One story with high-ceiling bays, 10,000 square feet ■ Location: Golden, Colorado ■ Heating degree-days: 6020 ■ Cooling-degree days: 679 ■ Construction cost: $1,127,000 ■ Date completed: June 1996 ■ Energy cost savings: $3,475 per year ■ Energy cost savings: 63% over base-case building The National Renewable Energy Laboratory’s Thermal Test Facility (TTF) is an open-plan labora tory/office building designed using a high-perfor mance, whole-building approach. The building is a showcase for integrated energy-efficiency features that significantly reduce energy costs, and it is a good example of how it pays to incorporate sustain- able design features. Additional costs for the sus tainability design features increased construction costs by only 4%. The energy costs for the TTF are 63% less than a building built to the Federal Energy Code (10CFR435). The energy cost saving includes a 50% reduction in energy consumption and a 30% peak power reduction. Approximately 75% of the lighting needs are met by daylighting. The main design features that made the TTF such an efficient building are: Energy-Efficient Features: ■ Building orientation ■ Energy-efficient lighting (T-8 fluorescent) with daylighting controls ■ Energy management system ■ Daylighting ■ Overhangs and side fins to block summer sun ■ Direct/indirect evaporative cooling (two-stage evaporative cooling) ■ Low-e window glazings ■ Separate fresh air system with air-to-air heat recovery Case Study Thermal Test Facility “Sustainability is basically a concept about the interconnectedness of the environment, the economy, and social equity. It is a journey – a path forward – through which we demonstrate responsibility for our future legacy. It is a vision – an aspiration – for a better life for our children and our children’s children.” – Statement of Unity, Federal Network for Sustainability, a project of the Federal Energy Management Program, Earth Day April 22, 2002 Warren Gretz Los Alamos National Laboratory Sustainable Design Guide 5 Chapter 1 | Sustainable Development – What and Why? Sustainable Development at LANL This document provides insight and guidance for making LANL's sustainable principles and goals a reality. LANL embraces the following principles and goals to achieve its vision for sustainable development. Principles – Maximize use of natural resources in the created building environment. Minimize energy and water use and the environ mental effect of buildings. Ensure processes to validate building system func tions and capabilities for proper maintenance and operations. Goals – Integrate Sustainable Design into project develop ment and execution processes. Construct sustainable high-performance buildings that are productive, inexpensive to operate, easy to reconfigure, sparing on their use of natural resources, and inherently protective of the natural environment. Provide LANL with sustainable buildings that offer a safe and secure work environment. Provide LANL with sustainable buildings that link together to form a sustainable campus. The LANL Sustainable Design Guide describes the process of developing leading-edge energy and environ mentally sensitive buildings. Prepared by the National Renewable Energy Laboratory (NREL) in conjunction with LANL, the LANL Sustainable Design Guide demon strates how to design and construct new-generation buildings. The goals of the earlier LANL Site and Architectural Design Principles are a springboard for specific guidance for sustainable building design. Sustainable design can minimize the environmental impact of new buildings and other facilities on the LANL campus and help retain the Laboratory’s most important asset: the LANL staff. Sustainable buildings can improve the overall health, comfort, and productiv ity of building occupants. Improving human comfort in staff workspaces allows LANL to attract and retain the best and brightest workforce required to meet the Laboratory’s core missions. ■ Lower cost to maintain ■ Reduced energy to operate ■ Lower air pollution release ■ Healthier and more productive occupants ■ Greater stability of national energy supplies ■ Less material usage ■ Longer building life Why build sustainable buildings? High-performance buildings are designed and built to minimize resource consumption, to reduce life cycle costs, and to maximize health and environmental performance across a wide range of measures – from indoor air quality to habitat protection. For example, high-performance buildings can: ■ Achieve energy savings in excess of 50% compared with conventional buildings ■ Achieve higher employee productivity and longer job retention ■ Reduce water consumption, maintenance and repair costs, capital costs in many cases, and overall environmental impacts.
