The long, barlike volume of the building is only 38 feet wide, so the interior of the single-story structure is airy and daylit from both sides. This reduces the need for artificial lighting during the day, especially in the relatively densely packed operations area, where there are no walls to inhibit daylight penetration. White walls and neutral finishes highlight the Douglas fir ceiling, which is constructed from tongue-and-groove decking over glulam beams. Often there is so much attention paid to photovoltaics or geothermal as a way of saving energy, Souza says, that low-tech solutions such as these are ignored.
