Why We're Green

Mazzetti has been designing energy-efficient buildings for almost 50 years. As sustainable design has moved into the forefront of responsible building technology, so has our reputation as sustainable design experts with recognized projects along the west coast. Mazzetti has participated in over 30 LEED® projects, ten of which are certified Gold. In addition, thirty percent of our staff is LEED Accredited.


“Mazzetti provided great value in innovation and exploration that balanced initial cost versus long term operational costs for a technically challenging and difficult project. There was a high emphasis on sustainability solutions for the building and the environment while also meeting the needs required for high acuity patients.” - Elizabeth Chaney
formerly of Lucile Packard Children’s Hospital
