Anchorage's first LEED-certified tower transforms skyline with sustainable design innovation
At a glance
The 14-story JL Tower stands as a testament to sustainable architecture in Anchorage, Alaska. This 280,000-square-foot Class A office building combines striking design with environmental responsibility, achieving LEED Silver certification while providing premium office space with panoramic views.
The challenge
Anchorage's commercial real estate market needed a modern, sustainable office tower that could attract and retain premium tenants while setting new standards for environmental design. The project required balancing ambitious sustainability goals with the harsh demands of subarctic climate conditions. The design needed to maximize energy efficiency and occupant comfort while creating an iconic addition to the skyline. Additionally, as the first LEED-certified building in Anchorage, the project had to navigate uncharted territory in sustainable design certification for the region.
Our response
RIM Architects, now part of GHD, delivered an integrated design approach that prioritized sustainability without compromising luxury or functionality. The sweeping glass facade maximizes natural light penetration and provides stunning 360-degree views while incorporating high-performance glazing for optimal thermal efficiency. We designed flexible, virtually column-free floor plates ranging from 36 to 47 feet in depth, allowing tenants maximum adaptability. The building includes state-of-the-art amenities like a 200-person conference center, fitness facility and business center. Our team's innovative design solutions helped achieve LEED Silver certification for Core & Shell Development 2.0, establishing new benchmarks for sustainable commercial construction in Alaska.
The impact
JL Tower has redefined Anchorage's commercial real estate market while demonstrating the viability of sustainable design in subarctic conditions. The project's success inspired two tenants to pursue LEED for Commercial Interiors certification, expanding the building's environmental benefits. The tower's striking profile has become a recognized landmark, while its high-performance design delivers long-term value through reduced operating costs and enhanced occupant wellbeing. This pioneering project earned the Associated General Contractors of Alaska's 2008 Sustainability in Construction Architect Award, establishing new standards for sustainable commercial architecture in the region.
