Unparalleled traditional design practices embrace site responsiveness, addressing resource conservation, erosion control, natural light, beautiful views, and weather protection. Excellent conventional practices look to local materials and construction techniques for cost effectiveness, durability, and cultural appropriateness. To manage both old and new methods, we have integrated the LEED - Leadership in Energy & Environmental Design - sustainable building system into our design processes. LEED provides a particularly useful tool for design and assessment of sustainable solutions. Because of our efforts, AHL is listed as one of the nation's Top 100 Green Design Firms, by the Engineering News Record.
