FlexLab - Lawrence Berkeley National Laboratory
FLEXLAB is a unique, completely customizable and configurable whole-building integrated systems test facility that was designed to study and develop systems level solutions, tools and processes for the commercial building market. Launched in July 2014, FLEXLAB has 4 testbeds focused on integrated building systems research including development and validation of simulation, design and operational software tools. Each testbed consists of two identical test cells - providing ideal conditions to conduct systems evaluations under controlled conditions. Integrated systems development and validation of related energy models requires subsystem level data on performance to enable algorithms to be fine tuned for reliable application. FLEXLAB provides energy monitoring at the device level, as well as high accuracy weather station equipment, flow measurement, and numerous temperature sensors both in the occupied space and embedded in the building structure to capture envelope performance conditions. FLEXLAB can replicate the thermal loads of almost all U.S. climate zones and provides feedback on energy performance as well as thermal and visual comfort, and other indoor environmental performance targets.

David Brower Center
The David Brower Center is a 45,000-sq. ft. 4-story office building for environmental non-profit organizations located in the heart of Berkeley. The Brower Center’s mission is to be a home for the environmental movement by advocating for the beauty, diversity, and ecological integrity of Earth. It was first occupied in May 2009 and was Berkeley’s first LEED Platinum building. The building design combines thermal mass, shading, and insulation into an efficient building envelope, daylighting and efficient lighting control strategies, and a low energy HVAC system. The primary space conditioning subsystem is hydronic in-slab radiant cooling and heating, often referred to as thermally activated building system (TABS). All cooling water in the building is provided by a cooling tower -- the building has no chillers. Ventilation air is provided by an underfloor air distribution system. An array of photovoltaic panels on the roof provides approximately 50% of the building's electricity needs.

Post-occupancy performance measurements by the Center for the Built Environment (CBE) at UC Berkeley have demonstrated excellent performance. The building's EnergyStar rating was 99 in both 2010 and 2014. The results of two occupant satisfaction surveys (2010 and 2014) showed high levels of satisfaction with all aspects of the building's indoor environment. Fred Bauman, CBE Researcher, will join the tour.

Tour #2

Stanford University - Central Plant and Engineering Quad

Thursday August 10, 2017

Bus departs hotel at 9:30PM
Returns no later than 4:00PM

Price: $60 per person, including lunch
(Limited to 50 people)

Stanford Central Energy Facility The Stanford Energy Systems Innovations project encompasses the best of both North American and European district heating and cooling system advances, with engineers, manufacturers, and constructors from both continents collaborating to develop this state-of- the- art transformation of Stanford into one of the most efficient district energy systems in the world. Aside from extremely efficient operations, sustainability features are incorporated throughout the Central Energy Facility so that it can serve as an example for generations to come.

The new Central Energy Facility (CEF) includes three large water tanks for thermal energy storage, a high-voltage substation that receives electricity from the grid, and an innovative heat recovery system that takes advantage of Stanford’s overlap in heating and cooling needs. Unlike the previous fossil-fuel- fired combined heat and power plant, the CEF is powered completely by electricity, which Stanford has committed to procure from renewable sources.

Stanford Engineering Quad
The new Stanford Engineering Quad consists of four buildings providing 600,000 square feet of flexible teaching, research, office, and social spaces. The Y2E2 building was the first of the four buildings to be completed and employs passive stack ventilation, daylighting via central atria, active chilled beam conditioning, and a host of other energy efficiencies strategies. The latter three buildings are also built to high standards and include extensive laboratory spaces. Time will also be provided to visit the adjacent historic Stanford Quad.
