SUSTAINABLE CONSTRUCTION RELIES ON Shared Goals
The statistics confront us every day. In the U.S., buildings consume 72 percent of total electricity and account for 13 percent of total water use, while construction activities generate nearly 26
percent of all non-industrial waste.
Green building design and construction demand a collaborative effort dependent on shared goals of the owner,
designer and contractor. An early commitment ensures a
holistic approach, resulting in smart decisions that benefit
the triple bottom line — people, planet and profit.
Airports and their support structures provide numerous
opportunities to reduce energy, water and resource consumption in the built environment through daily operations, new construction and upgrades to existing facilities.
Since airports house nearly all types of commercial

facilities (administrative, civic, hotels, restaurants,
manufacturing, maintenance, etc.), energy reduction goals
are tangible everywhere you look.
For example, a new hangar design in the southwestern
desert incorporates passive energy conservation measures
as part of the design approach to Leadership in Energy and
Environmental Design (LEED) Gold certification through the
green building rating system developed by the U.S. Green
Building Council (USGBC). The hangar’s stepped roof provides deep overhangs that shade a series of clerestory windows to reduce solar heat gain while introducing daylight. In
a climate where the expansive hangar doors are rarely closed,
the structure integrates a 20-foot-deep canopy over the full
length of doors to shade and to prevent excessive heating of
the concrete floor, while pre-cooling outside air used for ventilation. Natural convection is promoted by locating louvers
at the high points of the roof, to exhaust the warmest air and
