Lane Community College Downtown Campus – Lane Community College – Eugene, Oregon

 

Energy Modeling, Analysis, and Design Assistance

 

The Lane Community College (LCC) Downtown Campus, located in Eugene, Oregon, is an 188,000 sq.ft. mixed use facility consisting of two buildings.  The Academic Building (101,000 sq.ft.) provides educational space for LCC, office space for Lane Small Business Development and retail space for the Lane Store.  The Residential Building (87,000 sq.ft) provides student housing. The project represents the commitment made by LCC to environmentally-responsive design with a special focus on energy efficiency.  The $55 million project includes a state-of-the-art LEED Platinum Academic Building serving nearly three times the number of students than the former downtown site. The Academic Building opened in January 2013. The downtown campus also includes a LEED Gold student housing complex that accommodates 256 residents. The Residential Building opening in September, 2012.

 

Solarc worked closely with SRG Partnership, Robertson Sherwood Architects, and the University of Oregon’s Integrated Design Lab providing integrated design assistance to deliver an ultra-energy efficient design that would meet the project’s budget requirements. Solarc used a whole building energy modeling software (eQuest/DOE2). Deliverables included results of loads, and energy models performed to support and inform the emergent design concepts. In addition, eQuest/DOE2 was used to model the design for LEED energy credits, and incentive applications.
