design, construction, and operation; and using sustainable construction materials for construction of the Medical Center. Several aspects of the overall project's design serve to reduce otherwise occurring GHG emissions. These design elements include; 1) public transportation access is available for at least two public bus lines usable by future residents and hospital staff and visitors, 2) future residential units would be provided in close proximity to employment sources, thereby creating a walk -able community that would reduce vehicle trips; and 3) Kaiser Medical Center staff, patients and visitors would be expected to take advantage of on-site retail opportunities provided as part of the project. These design measures would reduce emissions associated with vehicle trips. The Medical Center would also implement a number of GHG reduction measures, in addition to the TDM program described above, that are derived from the Green Guide for Healthcare and specifically intended to reduce GHG emissions during operations. These features include: • secure bicycle racks and/or storage, with shower and changing facilities; • energy consumption at the hospital would be reduced by at least 3.5 percent over standard energy efficiency regulations, and by 10.5 percent over regulatory requirements in all other medical buildings; • roofing materials will have a Solar Reflectance Index equal to or greater than the values listed in the Green Guide for Healthcare Credit Goals on a minimum of 75 percent of the roof surfaces; • reducing natural gas consumption by 20 percent or greater using enhanced commissioning and enhanced refrigeration; • either not using refrigerants; or selecting refrigerants and heating, ventilation, and air conditioning (HVAC) equipment that would minimize or eliminate the emission of compounds that contribute to ozone depletion and climate change; • not using fire suppression systems that contain ozone-depleting substances (CFCs, HCFCs, or Halons); • lighting controls for a minimum of 90 percent of the building occupants would be provided to enable adjustments to suit individual needs and preferences; • natural lighting would be provided according to the standards of the Green Guide for Healthcare. Artificial lighting in areas where natural lights are supplied will be combined with solar sensors so that artificial lighting is only used when needed; • all urinals (but not toilets or bed pan washers) and all hand wash sinks (but not compounding sinks, housekeeping sinks, or sinks in toilet rooms for inpatient bed rooms) would be equipped with sensor operators. These GHG reduction measures would reduce GHG emissions from construction activities, and would minimize mobile, area source, indirect electricity, and solid waste emissions. However, the nature of the proposed project is such that mitigation cannot fully address its GHG emissions. Therefore, the GHG emissions of the project and the project's contributions to global climate change would remain significant and unavoidable.
