The Energy Biosciences Building is home to a world-class research institute charged with developing sustainable fuel technology. Located in downtown Berkeley, this University of California Facility houses 113,000 sf of laboratories, offices and collaborative workspace for molecular and microbial biology, greenhouses, offices and workrooms for biofuels research and development. L+U developed a daylighting and lighting design tailored to the needs of intensive laboratory use while supporting the low energy requirements of LEED Platinum and the aesthetics of a visible research landmark.

SERVICES

Daylighting improves the quality of visual comfort while reducing energy use. We use scale physical models and calibrated simulations with RADIANCE software and proprietary scripts to:
• Predict and evaluate illumination levels and light distribution
• Predict and analyze luminance gradients and glare potential
• Analyze thermal and energy use implications of daylighting design
• Design and evaluate daylighting to exhibition and curatorial performance criteria
• Predict energy savings from daylight harvesting
• Coordinate daylighting and electrical lighting design
• Post-occupancy HDRI analysis of luminance and visual comfort

We provide full-service lighting design for building interiors, exteriors and landscape as well as specialized lighting for art. We work with the architect to reflect the aesthetic of the design and support the spatial experience with high performance and visually comfortable lighting.
• Specify luminaires, sources and layouts for electrical lighting
• Provide accurate renderings of lighting for evaluation
• Provide illumination levels for design evaluation as well as code requirements
• Provide lighting controls narrative and diagrams
• Arrange desk-top, lighting lab and/or in-situ mockups as appropriate to the project
• Provide aiming and lighting control observation
• Design custom fixtures
• Provide LEED credit documentation for lighting credits

Visual and thermal comfort in high-performance buildings rely on integrated glazing and curtain wall design. We use advanced simulation techniques to:
• Analyze visual performance of glazing alternatives
• Evaluate advanced glazing applications, including light redirecting glass and internal shading systems
• Predict and evaluate thermal performance of curtain wall systems
• Predict occupant comfort conditions for curtain wall alternatives
• Identify and coordinate value engineering tradeoffs for integrated high-performance facades

Effective shading reduces glare and minimizes solar heat gain without impeding the use of daylight for visual tasks. We assist the architect to design shading appropriate to the program, the climate and context of the project. We use scale physical models and calibrated models with RADIANCE software to:
• Analyze site conditions for solar access and shade potential
• Design sun control and glare control alternatives for local skies and climate conditions
• Evaluate shade alternatives for visual and thermal comfort

The laboratories and other workspaces are lit with daylight and electric light that controlled to supplement daylight. To support the demanding visual tasks of the laboratory benches, L+U designed a user-friendly task lighting strategy that provides the required high levels of illuminance but that also efficiently switches task lamps off based on occupancy. This work involved developing custom solutions, including an occupancy sensor hood to limit its field of view and a dimming sequence designed to adjust light levels unobtrusively.

Landscape features and egress paths are lit to work within the LEED dark-sky and light trespass requirements. Careful and subtle lighting at the exterior also allows the interior lighting to draw visitors into the lobby where a luminous stair provides a connection to all floors. L+U carefully tuned the light levels throughout this experience, using simulation and a full-scale physical mockup of the stairway assembly.
