- 25% reduction in impervious surfaces from the existing conditions, minimizing storm water runoff.
- On-site storm water management that removes 80% of Total Suspended Solids (TSS).
- High albedo materials cover 80% of the building roof area to minimize heat island effect.
- Preserved open space is a combination of protected existing habitat and restored native plantings.
- The building systems and envelope design account for a building energy performance that is 26% more efficient than the baseline case.
- A 40% reduction in water usage in the building is accomplished through low-flow fixtures.
- The materials used in the projects include 30% recycled content, 30% regional sourcing, and FSC certified woods.
- Interior spaces welcome daylight from window walls at two ends and ceilings sloping to a continuous light monitor (Maryland House) and a hovering clerestory pop-up (Chesapeake House).
Interstate 95 Maryland House and Chesapeake House Travel Plazas won USGBC Maryland’s 2015 Small Commercial Project award! This award was presented by USGBC Maryland Wintergreen, the organization’s annual recognition of high performance, healthy building design by USGBC Maryland region projects, businesses, and chapter members. The event was hosted at the Horseshoe Casino Baltimore in mid-February and was attended by two hundred green building professionals and leaders. See full list of winners The Maryland House and Chesapeake House Travel Plazas project scope included the redevelopment of both existing rest stops on I-95 in Maryland. The rest stop typology is inherently automobile-driven and emerged as a result of traveler dependence on the conveniences of fuel, food, and facilities. Ease of access is key and both projects are sited in gap spaces between the northbound and southbound lanes of the highway. The projects serve more than 5 million annual visitors and the project was challenged to both maintain the programmatic necessities (surface parking, large fixture counts, etc.) and promote sustainability. The design promotes sustainability through the integration of outdoor patios and paths softened by indigenous plantings and infused with interpretative site signage to engage and educate visitors about the significance and beauty of the natural landscape. The site redesign also provided opportunities for the design team to improve the surrounding habitats and watershed through a remediation and rebuilding of existing subgrade storage tanks at service stations, the introduction of engineered site design facilities, and strategically located native plantings. The team also minimized site disturbance by building on the footprint of the existing facilities. To optimize building performance for the 24 hour-a-day operations, the projects work to incorporate daylight and provide a high performance building envelope.
