Whether it’s a sprawling transportation hub or medical institute, there are many options for incorporating sustainable design into buildings. On tours of the National Cancer Institute (NCI) and the Equipment Maintenance and Transit Operations Center (EMTOC) in Maryland during this year's Better Buildings Summit, participants saw first-hand how two very different building types can achieve great gains in energy efficiency.

NCI utilizes green roofs, living walls, efficient parking facilities, and state of the art indoor lighting systems (with daylighting). The 580,000 square foot healthcare facility has achieved 57 percent energy savings from its 2007 baseline and saved over $2 million in energy costs. NCI also harvests condensate water for landscaping. The attention to the external environment extends to a storm water retention pond and a native adaptive landscape. As of 2015, the building’s ENERGY STAR score was 94, demonstrating superior energy efficiency.

During the tour of the EMCOT in Montgomery County, Md (the most highly attended tour of all tours hosted during the Summit), attendees learned the hub occupies 41.5 acres. That's a 5-building campus employing 400 staff members and providing services for over 150 trains and buses. It operates 24 hours a day, year round. EMTOC’s key energy efficiency features include daylight maximization, radiant floor heating, real-time energy monitoring, solar rooftop installations, insulation and weather stripping/sealing, compressed natural gas (CNG) compressors, and CNG buses.

Like NCI, EMTOC also pursues water efficiency measures. The facility is piloting a rain harvesting water recycling system from their 4-acre green roof, reusing rain water for toilets and bus-washing. The program has saved over $500,000 in the first year; the current bus-washing water is 70 percent recycled. The facility has installed two 20,000-gallon storage tanks, sub-metered to separate water from sewer usage
