Description

The recently completed Integrative Genomics Building (IGB) Laboratory on the Lawrence Berkeley National Laboratory (LBNL) campus, a 77,000 square foot facility consisting of wet/dry laboratories and office spaces, is helping the University of California (UC) meet aggressive sustainability goals through efficient design and prioritized ongoing operational performance. The project has eliminated onsite carbon emissions from space and water heating. Combined with passive design strategies, the IGB includes innovative elements such as heat pumps, heat recovery, radiant floors, chilled beams, integrated HVAC-lighting occupancy controls, and plug load controls. However, adding technology to the building system does not automatically result in efficient operations—high performance buildings often increase complexity, require integration of many systems, and demand additional operational resources. Using the IGB as a case study, this presentation will discuss new construction commissioning (NCCx) and ongoing commissioning (OCx) challenges in all-electric buildings. The speakers will introduce the need for a new management approach to operating buildings through an ongoing process to resolve operating problems, improve comfort, optimize energy use, and identify future retrofit opportunities.
