Group14 provided commissioning services, EDA, and energy modeling for two office projects on Trimble’s 15-acre Westminster campus. The first project was a 124,556-SF, four-story office building, which was completed in 2013. The second project, completed in 2019, consisted of a 118,039 SF, four-story office building that connects to the first building via a pavilion and connector breezeway.

After Trimble’s second office was completed, our existing building team was hired to perform energy audits for the Westminster facilities.

Group14 was later contracted to perform a sustainability assessment for nine Trimble sites across the country. The sustainability assessment included greenhouse gas (GHG) emissions reporting and setting sustainability goals as part of the organization’s larger Corporate Social Responsibility (CSR) efforts.


The LEED Gold facility is heated and cooled by indirect/direct evaporative cooling, with heat recovery and high efficiency condensing boilers. The building is also equipped with LED lighting throughout. The energy savings measures helped reduce power costs by 33.2% when compared to a baseline facility.

The project also achieved a 20% water reduction and an energy cost savings of 28%.

Group14’s commissioning work helped achieve a 30% reduction in requests for information about building systems during construction, which resulted in finishing the engineering layout a month faster than projected.
