Construction of Efficient, Cost-Effective and Sustainable Maintenance Facilities

The Oregon Department of Transportation (ODOT) manages about 89 maintenance stations. Many of these are reaching or beyond their life expectancy, inefficient, or functionally obsolete (e.g., unable to accommodate large modern equipment). There is an urgent need to systematically replace these buildings to support the maintenance mission of the agency. By reviewing literature, green building standards and rating systems, and other DOT regulations, and by conducting two case studies as part of an ODOT research project (SPR 792), best practices were identified to be considered when constructing new or renovating existing stations. First, optimizing building energy performance appears to be the single most important action that can result in cost savings and reduce its negative environmental impacts. To optimize energy use, it is important to perform initial commissioning of building systems ensuring that the HVAC and electrical systems (including sensors) are operating per manufacturer recommended specifications. Then, using building energy simulation tools is recommended to optimize energy performance and to identify areas where energy can be saved, or where waste energy can be harvested. Next, it was found that making improvements in sustainability metrics for materials used in the greatest quantity on a mass (or volume) basis can result in significant improvements in overall sustainability performance. Also, prioritizing the use of regional materials for the most used building materials, especially those of greatest density (e.g., concrete), can significantly reduce environmental impacts of associated transportation, as well as stimulating the local/regional economy. Finally, focusing on materials that provide synergistic benefits in energy savings was found to be important for improving the overall sustainability performance of buildings.
