The Bill & Melinda Gates Foundation Headquarters
The Bill & Melinda Gates Foundation headquarters is located in downtown Seattle and is a multi-phased contiguous office campus of three buildings totaling one million SF, as well as underground parking facilities. Two of the three buildings were constructed in Phase I of the project—one of which includes a 15,000-SF visitor’s center that explains the Foundation’s work in global health, development and education. The project includes underground rainwater collection and thermal energy storage. A “green roof” structure with plant materials covers most of the lower level roof areas. Extensive landscaping with water features, sidewalks, plaza and other site work will be constructed throughout the 12-acre campus.
EEI was hired as the Commissioning Authority for this impressive LEED Platinum project. In that role, EEI provided a commissioning plan that detailed and guided the process, wrote the commissioning specifications, reviewed design and construction documents, provided functional test procedures, and performed functional testing of the following systems and equipment:
- Mechanical HVAC equipment
- Central plant equipment (heat recovery chiller, exchangers and pumps)
- Energy management and monitoring system
- Building automation system
- Domestic water, pumping and mixing systems
- Occupancy sensors
- Lighting controls and daylighting controls
- Emergency electrical systems
- Uninterruptible power systems
As a requirement of LEED certification, EEI provided the recommissioning manual that summarizes the building operations from conception through construction, EEI also provided a post-occupancy review that verified operations and resolution of all outstanding issues.
