At this early stage, Stanford is committed to achieving or exceeding a rating comparable to the LEED Silver rating.  Examples include preserving green space through the choice of building site, using environmentally friendly materials in the construction of the building (see table below), and driving better efficiency in the mechanical systems to save 2.5 million kWh per year (the equivalent of 375 California homes).  In addition, Stanford has set a goal of a 20% reduction on the pertinent mechanical standards for this building (20% of ASHRAE 90.1). 

  • Install a highly-efficient energy management system that will reduce energy consumption of a typical research building by approximately 25%
  • Improve freezer management by replacing old freezers, purchasing only energy-saver units, and allowing a certain fixed number of freezers in the building
  • Capitalize on natural light by installing a state-of-the-art light management system that adjusts light levels as the day progresses, thus reducing electricity use
  • Reuse and/or reclaim water by installing low-flush toilet fixtures that will be serviced by water from reclaimed sources
  • Protect, preserve or eliminate the use of water by designing thoughtful landscaping -with any water used being drawn from a gravity-fed bio-swale system located on campus

Sustainability Building Elements


  • Low flow/waterless plumbing fixtures throughout
  • Process water efficiently
  • Gray water system making use of wastewater from an adjacent facility
  • Storm water from roofs treated for water quality via vegetated swales (rather than via mechanical/constructed means)
  • Onsite storm water infiltration (rather than sent into the strom sewer)
  • Secure bicycle parking and shower/changing facilities to encourage alternative transportation


  • Optimized shading design to reduce solar heat gain
  • Window systems and ceilings designed to admit daylight and offset use of electric lighting
  • White, Energy Star compliant roofing to reflect heat from the sun, thus lowering cooling demand and mitigating the urban heat island effect

Material Impacts

The design team is proposing to use both recycled content, rapidly renewable resources and lox VOC interior materials throughout the facility.  Examples of the proposed materials include:

  • Carpet with recycled content nylon
  • Bio-based composition tile and/or recycled content floor tile, in lieu of traditional VCT
  • Recycled content terrazzo tile
  • No VOC, latex paint
  • Bamboo veneer for lab casework and interior doors with MDF core; no urea formaldehyde additives
  • FSC certified wood products where bamboo is not specified
  • PVC free shade cloth at window coverings
  • Materials that meet the 500 mile radius LEED requirement

Indoor Air Quality

  • Wind tunnel testing of building model to minimize re-entrainment of exhaust air
  • Operable windows, where practical, offset cooling and allow a diret connection with the outdoors

Mechanical Systems

  • 20% target energy reduction based on 2005 California Energy Efficiency Standards – Title 24
  • Portable measurement provisions for monitoring individual lab equipment power consumption
  • Measurement and optimization systems for building energy and water consumption

  • Permanent monitoring system
  • Provide monitoring and control of fume hoods and room pressure
  • Indoor environmental safety – fume hood commissioning, alarms
  • Increased building wall and roof insulation
  • Best available glazing systems: 0.25 to .029 Shading Coefficient
  • Variable volume laboratory air handling systems
  • Low velocity filter banks  400 ft per minute or less
  • Low pressure supply air handling systems
  • Low duct air velocities – 1500 ft per min maximum with a target of 0.06” to 0.1 range pressure drop per 100ft of duct
  • Seal all duct systems and leak test (all or spot-check) ducts
  • Variable speed pumping for Chilled Water systems
  • Variable speed pumping for Heating Hot Water system
  • Reverse-return piping
  • Premium efficiency motors
  • Use of limited combination sash fume hoods
  • Un-occupied hours setback space air change rates
  • Un-occupied hours setback temperatures
  • Chilled water temperature reset
  • Heating hot water temperature reset
  • Supply air temperature reset based on critical zone
  • Supply and exhaust duct static pressure optimization based on critical zone
  • Domestic and industrial hot water circulator scheduling for occupied hours of operation
  • Heat Recovery at exhaust system
  • Space lighting control scheduling

Electrical Systems

  • 20% target lighting energy reduction based on 2005 California Energy Efficiency Stds – title 24
  • Right-size laboratory electrical distribution panels and transformers by utilizing data obtained from comparable laboratory space
  • Permanent or portable measurement provisions for monitoring individual laboratory equipment power consumption
  • Measurement and optimization for building energy

California Energy Efficiency Standards – Title 24

The design goal is to exceed standards by at least 20%; will attain through:

  • T8 or T5 lighting at approximately 1.0 watts/SF
  • Photo sensors for daylight harvesting
  • Occupancy sensors
  • Optimum lamp/ballast combinations
  • Highly reflective surfaces for light fixture housings similar to “MIRO Micro Matt”
  • High efficiency transformers

Plumbing Systems

  • Reduce potable water usage inside the building. Low-flow fixtures are used and waterless urinals are under consideration
  • Eliminate process water usage inside the building
  • Reclaim water for toilet flushing

The campus and the design team are fully committed to meeting their respective sustainability goals.  In addition to these programs, the School of Medicine plans to manage and operate the building in a manner that reduces waste, recycles materials and reuses material where possible.

We are committed to building and operating the Lorry I. Lokey Stem Cell Research Building in an environmentally friendly manner to minimize effects on the environment.
