Standard 90.1-1999 budget case building. The model predicted annual energy use of 226,340 kWh, or an EUI of 29.1 kBtu/ft2 · yr. After two years of operation, the project had an average annual energy use at 233,633 kWh. The energy use intensity is 30 kBtu/ft2 · yr; within 3% of the energy model prediction. (The model was not recalibrated to reflect actual operating conditions.) Because the NWMC project includes many types of uses, a comparison to a “typical” building is not straightforward. Table 1 illustrates a weighted average EUI for the types of space uses in the NWMC project compared to the 2003 CBECS averages. With an EUI of 30 kBtu/ft2 · yr, the Northwest Maritime Center ranks among the lowest energy use buildings in the country. Environmental Impacts The NWMC is located on the site of a former sawmill, a shipyard and deep draft dock, and most recently an oil terminal. The site was deemed an “intrusion” in the National Historic Landmark district, and was purchased by the citizens of Port Townsend for remediation into a community hub with public access to the shoreline. More than 2,400 tons of contaminated soil was removed to remediate the site prior to construction. In addition to the project’s energy efficiency measures, the design aimed at improving the shoreline habitat for juvenile salmon and other fish vulnerable to predators. Great care was taken in designing the new pier, which serves as the focal point of the center’s on-thewater educational programs. The new pier was constructed for moorage of larger historic vessels, the ability to attract major events, educational opportunities for children through sailing programs, and other hands-on/on-the-water events. Extending 215 ft into the bay and encompassing 4,900 ft2, the pier provides a safe place to enjoy the area’s natural beauty while learning about native flora and fauna. The pier design minimizes shading of the eelgrass planted to restore over 3,000 ft2 of shoreline habitat for the salmon fry. Eelgrass is a critical and sensitive habitat for fish (including threatened PERFORMING BUILDINGS 37 m o n t h ly E n E r g y U s E , 2 0 0 9 – 2 0 1 2 TA B L E 1 E n E r g y U s E I n t E n s I t y C o m pa r I s o n primary Uses Boat Storage (Livery) Meeting Rooms, Commercial Kitchen Chandlery (Retail Store) Boat Shop, Craft Auditorium Of ces, Classrooms, Library, Pilot House total project nWmC actual EUI Area (ft2) 2,850 3,700 4,300 6,200 9,500 2003 CBECS EUI 77 76 82 66 72 2003 CBECS Category Service (Vehicle Repair and Service, Postal Service) Education Retail Public Assembly Of ce 26,550 73.3 kBtu/ft2 · yr (CBECS weighted average) 30 kBtu/ft2 · yr (2009–2011) Summer 2012 HIGH
