Grand Canyon Association Bookstore

Grand Canyon National Park, Arizona

This building, located at the Mather Point visitor orientation plaza of Grand Canyon National Park, is designated as an exemplary building by the U.S. Department of Energy. It features a passive solar heating system, a night flush cooling system and a computer controlled climatic response system. To reach the Department of Energy's "exemplary" designation level, a 70% energy reduction over a standard building was required. The energy systems were designed in conjunction with the National Renewable Energy Laboratory.

Sustainable strategies include:

The stonework on the building was scavenged from the site.

Trees were relocated rather than being removed.

A metal roof was used for longevity and recyclability; structural steel had a high-recycled content.

Concrete used had a high percentage of fly-ash content for thermal storage.

All lumber throughout the building was certified as sustainably harvested.

All construction debris was recycled.

Radiant low-energy back-up heating and low-energy evaporative backup cooling supplements the passive solar systems.

Lighting energy is limited to 1.25 watts per square foot, and high level day-lighting sensors are interlinked with artificial lighting to reduce energy usage.

All interior fixtures use FSC (Forest Stewardship Council) certified wood or strawboard.

All painted steel used zero-VOC (volatile organic compounds) paint and walls were constructed of tinted plaster.
