In honor of Earth Day, here's a look at new restaurants, corporate event venues, hotels, conference centers, and private rooms across the United States and Canada that factor the environment into their design or operations. Many of these new and renovated venues have LEED certification from the U.S. Green Buildings Council or another certification group. They can accommodate groups large or small for private and corporate events, conferences, meetings, weddings, business dinners, teambuilding activities, cocktail parties, and more.

The Westin Denver International Airport hotel received Platinum LEED certification in March. One of only three hotels to achieve a Platinum rating, the hotel—which was designed by global architect Gensler and built by M.H.S.—has a design that reduces energy costs by 49 percent and energy use by 43 percent. The hotel also uses 30 percent less water than conventional designs, with features including high-efficiency mechanical systems, wall-to-wall windows in its 519 guest rooms and 35 suites, and a pre-conference foyer that maximizes daylight heat. Other sustainable design features include low-flow showerheads, demand-control ventilation, and load-shedding escalators. For meetings and events, the hotel has 37,500 square feet of space that includes 19 rooms, the largest of which holds 850 for receptions. Additionally, the hotel has a 60,000-square-foot plaza that holds as many as 2,500 for receptions.

Offering 1.4 million square feet of exhibit space, the Georgia World Congress Center in Atlanta is the largest LEED-certified convention center in the world. In March, the venue unveiled numerous energy-saving upgrades as part of its $28 million Guaranteed Energy Savings Performance Contracting (E.P.C.) project with Trane, which began in 2015. The project included replacing equipment in the convention center's Building B central plant with custom-built chillers; replacing the center's interior, exterior, and exhibit hall lighting with more energy-efficient lighting; recycling construction waste; and upgrading on-site water feature motors. The upgrades are expected to reduce the venue's carbon footprint by 39 percent annually. For events, the venue has 12 exhibit halls, 106 meeting rooms, two grand ballrooms, and a variety of outdoor spaces.

The Monterey Conference Center in Monterey, California, is slated to debut its $60 million renovation this summer. The venue, which has been closed since 2015, is aiming to earn a Platinum LEED certification as part of the city's commitment to sustainability and the environment, which includes programs such as the Green Building Ordinance, free recycling, the Commercial Food Scrap Collection Program, and the Environmentally Preferred Purchasing Policy. Once reopened, the conference center will offer 40,000 square feet of flexible meeting and event space that will accommodate as many as 3,200 standing.

The Anaheim Marriott in California debuted a newly installed commercial solar system on its roof in January. Located above the Platinum, Grand, and Marquis ballrooms, the photovoltaic system—which includes 1,805 solar modules—fuels the daily power of nearly a third of the hotel's 1,030 guest rooms. The system is projected to produce 880,000 kilowatt hours of power annually, which will reduce the hotel's yearly energy consumption equal to the elimination of greenhouse gas emissions from 131 passenger vehicles. For meetings and events, the hotel offers 44 rooms, the largest of which holds 3,515 reception-style.

Italian-American eatery Faun opened in Brooklyn, New York, in August 2016. Designed by owner and architect David Stockwell, the space was built with numerous reclaimed elements—a notable feature is a sycamore bar made from a local tree that was cut down after Hurricane Sandy. The menu, helmed by chef Brian Leth, offers dishes made with ingredients sourced from local purveyors and an on-site 950-square-foot garden that grows crab apples, cherry tomatoes, figs, a number of herbs, and more. A variety of flowers also are grown in the garden, providing a habit for butterflies and bees. The garden is fertilized with compost made from a portion of the restaurant's kitchen scraps. The space, which is available for buyouts, seats 46 inside and 50 outside.

The first LEED-certified hotel in Charleston, South Carolina, the Beach Club at Charleston Harbor Resort & Marina opened at the end of 2016. The 92-room hotel is part of the Clean Marina Initiative, as it meets the environmental performance criteria for factors such as hauling and storying boats, boat sewage collection, hazardous waste management, and used oil management. The hotel's Fish House restaurant is part of the Sustainable Seafood/SC Aquarium Good Catch Partnership, committed to serving sustainable seafood. The hotel, which also has a green linen initiative, has 40,100 square feet of indoor and outdoor space for events that accommodates as many as 1,900 standing or seats 100 for classroom-style meetings.

The 2,000-square-foot restaurant, which seats 90, offers communal seating with tables that were created locally with reclaimed wood from the family-run business Square Nail. For private dining, the restaurant offers the 10-seat Sage room and the 36-seat Celadon room.
