We need light outdoors at night for safety, security, productivity, and enjoyment. Guidelines and technologies available today can help meet these lighting needs while providing good quality lighting that minimizes light pollution, conserves energy, and enhances community ambience, including the effect on wildlife and our view of the starry night sky.

Elevators in modern buildings are faster and more comfortable than their counterparts decades ago. But even when you are standing inside an innovative looking elevator cab, it is hard to identify the green features in the elevator and recognize their energy savings. This issue of e-News details major sustainable features in elevators and escalators and some design considerations.

On a sunny summer day, a typical roof surface can reach temperatures that are nearly 100°F above the ambient temperature. A cool roof, by contrast, stays at or near the ambient temperature due to the characteristics of its outer layer.

Using the integrated energy design approach, designers can cost-effectively lower building operating costs while improving workers' comfort and boosting productivity.

In libraries, lighting typically consumes more energy than any other end use. Consequently, the design team for the Multi-Agency Library at the College of the Desert decided to take advantage of the abundant natural light available in this desert climate to reduce energy use. This strategy directly resulted in strong architectural elements that delineate the building, making it a readily identifiable icon for the college campus and the surrounding community.

Traditionally, skylight wells in large, low-rise commercial buildings have been custom designed and site built, an expensive and labor-intensive process. This design brief explores the benefits of a better alternative: splayed modular skylight wells specifically designed for use with suspended ceilings.

Situated near a lake in the desert above the Mojave River, the new Learning Resource Center at Victor Valley Community College provides more reading and study areas, book stacks, conference rooms and offices to the college's existing library. The building's form (including its central skylight, roof monitors, and angled shading devices) provides dramatic natural lighting in the addition's reading areas.

Using fundamental components of the Daylighting Designer's Toolkit, designers can improve the visual environment, create a higher-quality space, and lower energy costs for buildings.

Not all energy-efficiency measures are appropriate for all building types, but some are especially useful for particular buildings. This Design Brief reminds designers and builders of opportunities they should consider in each of their projects.

A few building simulation runs early in a project can lead to design solutions that, though they appear simple, significantly improve building energy performance.

The new Oak Park Library in Ventura, Calif., integrates state-of-the-art energy-conserving design into a new joint-use public and high school library. The project demonstrates how to create buildings that are comfortable, environmentally responsible, and economical to operate.
