Macrina bakery owner Leslie Mackie has opened her third retail shop, but this time, she’s gone sustainable. Mackie’s hoping to secure LEED certification for the new space (on the corner of 1st Ave. South and South Holgate St.) by year end. What does that mean? From the Mackie camp: “In order to attain a Silver-level LEED (Leadership in Energy and Environmental Design) rating from the U.S. Green Building Council, Macrina had to comply with a list of requirements that includes: natural light sources and vents, certified wood, motion sensor faucets and energy efficient lighting, low VOC paints and stains, low-flush toilets and re-purposed kitchen equipment. Macrina is also lessening their footprint by purchasing green power from Seattle City Light.”The SODO cafe is currently serving just pastries and lunch. But Mackie says as soon as she’s settled, she’ll throw a weekend brunch into the mix.
