LEED Buildings Not Always More Efficient

Research conducted by several researchers from the National Research Council Canada—Institute for Research in Construction, Ottawa, Canada, reveals some interesting information about the energy performance of LEED buildings. The researchers conducted a re-analysis of data supplied by the New Buildings Institute and the U.S. Green Building Council. The energy use data was from 100 LEED certified commercial and institutional buildings. The data was compared to the energy use of the general U.S. commercial building stock. The researchers also examined energy use by LEED certification level, and by energy-related credits achieved in the certification process.

On average, LEED buildings used 18 to 39 percent less energy per floor area than their conventional counterparts. However, 28 to 35 percent of LEED buildings used more energy than their conventional counterparts. Further, the measured energy performance of LEED buildings had little correlation with certification level of the building, or the number of energy credits achieved by the building at design time.

The researchers concluded that, at a societal level, green buildings can contribute substantial energy savings, but further work needs to be done to define green building rating schemes to ensure more consistent success at the individual building level. While the researchers did not focus on hotels in their work, their findings should ring alarm bells for any architect, owner or developer involved in the construction of LEED-ready hotels. Energy savings are not always a given.

California Tops LEED Hotels List With Seven

by Glenn Hasek May 19, 2009 08:14
Interest in the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Certification program continues to grow with 21 hotels now certified. California, with seven hotels, is the state with the most hotels represented. The seven properties include: Hotel Carlton, San Francisco; Montage Hotel Beverly Hills; Orchard Hotel, San Francisco; The Ambrose, Santa Monica; Northstar Village Phase 3, Truckee; GAIA Napa Valley, American Canyon; and Orchard Garden Hotel, San Francisco.

So far this year, six properties have been certified. In 2008, seven earned that honor. In 2007: four. One property was certified each year from 2004 to 2006. One also earned certification in 2000. In addition to the seven California properties mentioned above, the other certified ones include: Sandpearl Resort, Clearwater, Fla.; CityFlats Hotel, Holland, Mich.; Posada Del Mike Rapu, Easter Island; Hotel Terra, Teton Village, Wyoming; Element Hotel, Lexington, Mass.; Proximity Hotel, Greensboro, N.C.; Avalon Hotel and Spa, Portland, Ore.; The Palazzo, Las Vegas; The Lodge and Spa at Callaway Gardens, Pine Mountain, Ga.; Unity Village Hotel and Conference Center, Kansas City, Mo.; Hilton Vancouver Washington; University of Maryland University College Inn and Conference Center, Adelphi, Md.; Len Foote Hike Inn, Dawsonville, Ga.; and the Kandalama Hotel, Damulla, Sri Lanka.

One property has earned LEED Platinum (Proximity), six properties have earned LEED Gold, seven have earned LEED Silver, six have earned basic certification, and one has earned LEED Bronze (Bronze category no longer available). Hundreds of other properties have registered to pursue LEED certification.
