Project Information:

The Lillis Business Complex, University of Oregon
Construction cost: $28.5 million
General contractor: Lease Crutcher Lewis, Portland, Ore.

The new 145,000 square-foot building at the heart of the Lillis Business Complex will make the most of natural advantages by harnessing prevailing breezes for cooling and the sun for heat, light and electricity. The structure will be fifty percent more energy-efficient than state code requires.

The building's energy conservation measures will include carefully positioned rooms that can be used almost year-round without electric lighting; external shades and light shelves to regulate temperature; "smart" lighting that adjusts to daylight levels; and sensors that turn off lights and other non-essential items in unoccupied rooms.

An extensive ventilation system and extra thermal mass in the building's concrete structure will enable it to retain more heat on cold days and stay cool naturally through most hot days. Several photovoltaic panels will generate a projected 35 kilowatts of clean solar energy.

The building also will save water through low-flow fixtures and an "eco-roof," which will use rain to grow beneficial vegetation rather than allow it to run off.

Builders will utilize "green" components such as materials salvaged from the previous building, certified hardwoods and other sustainable resources.
