ASHRAE’s New Publication Provides Energy Efficiency Guidance for Hotels

June 19, 2009

ASHRAE’s new publication, Advanced Energy Design Guide for Highway Lodging, contains recommendations on how to achieve 30 percent energy savings over minimum code requirements. This guidance for new hotel design is the first step toward achieving a net-zero energy hospitality facility.

“The recommendations allow the building industry to create more energy-efficient hotels while maintaining the quality and functionality of the space to provide a pleasant guest experience,” said Ron Jarnagin, chair of the committee that wrote the book, which gives architects, engineers, contractors, and other building team members the guidance they need to achieve advanced levels of energy savings without the need for detailed calculations of analyses.

The guide focuses on typical four-story (or less) hotels found along highways that have up to 80 rooms that use unitary heating and air-conditioning equipment. The recommendations in the guide are targeted for new hotels, but some design tips included can help existing hotels as well.

Suggestions in the guide include optimizing daylighting or using occupancy sensors in indoor corridors to reduce lighting costs; using compact fluorescent lighting in downlights, wall sconces, and table lamps instead of less-efficient incandescent lighting; using compact fluorescent fixtures with electric ballasts in all plug-in table and floor lamps in guest rooms, lobbies, and common areas; using low-flow shower heads and lavatory faucets; and using water-conserving commercial washers for laundering services.

The Advanced Energy Design Guide for Highway Lodging was written in partnership with the American Institute of Architects, the Illuminating Engineering Society of North America, the U.S. Green Building Council, and the U.S. Department of Energy. It is available in a free electronic download form at www.ashrae.org/freeaedg, and hard copies are also available in the ASHRAE Bookstore on the same website for $62 (or $53 for ASHRAE members).
