A brief description of how green cleaning is incorporated into cleaning contracts:

As noted in the UC Sustainable Practices Policy, UC San Diego prioritizes purchasing of products that have received the following third-party certifications and ratings: GREENGUARD®, Green Seal®, UL ECOLOGO, and EPA Design for the Environment Program's Safer Choice.

Additionally, UC San Diego has recently adopted a campuswide Green Cleaning policy (included in additional documentation) that is being submitted to GBCI as campus LEED O+M Master Site credit. The policy includes specific sustainability criteria related to purchasing cleaning supplies and hand soaps that will result in the following:

- Ensure that 80% of all cleaning products, by cost, meet LEED sustainably criteria, and maintain an 80% or greater threshold when purchasing cleaning products for in the future. This will reduce the exposure of building staff and occupants to potentially hazardous chemical, biological, and particle contamination.

- Ensure that 40% (or greater) of all cleaning equipment, by number of units, meet LEED criterion for green cleaning equipment. For existing equipment that does not meet the criteria, develop a phase-out plan for its replacement with environmentally preferable products at the end of its useful life.

- Strive to follow the operating procedures that have been established for hard floor and carpet maintenance while being aware of the varying health related sensitivities of all employees.

- Select strategies to promote and improve hand hygiene.

- Administer annual staff training workshops for the proper storage, handling and use of cleaning products and equipment. Furthermore, all new employees handling cleaning products and equipment must be provided training before performing duties.

- Put in place a method for occupants to express their opinions on the effectiveness of janitorial duties. Changes should be made as necessary to maintain a level of comfort for all occupants.

- Select strategies to reduce the effects that cleaning has on energy and water usage and the introduction of toxic chemicals in to the building.

- Select and appropriately use disinfectants and sanitizers to reduce levels of chemical, biological, and particulate contamination in the building.

- Develop and implement a contingency plan to manage staffing shortages under a variety of conditions to ensure that basic cleaning services are met and critical cleaning needs are addressed. Include a process to obtain occupant and custodial staff input and feedback after contingency plans are implemented.

Of the institution's uncertified building space, what percentage of floor area is maintained in accordance with an energy management or benchmarking program? (0-100):

A brief description of the energy management or benchmarking program:

UC San Diego's energy program has been nationally recognized for its leadership and innovation in applying state-of-the-art energy management practices to minimize campus environmental impacts. The following are some examples of how we have been able to reduce our energy use and carbon emissions, despite its significant growth over the past several years:

- Since 2001 UCSD's highly efficient, ultra-low emission cogeneration plant has generated over 75% of the La Jolla campus' energy.

- Development and implementation of a comprehensive energy efficiency program that has resulted in the completion of over $100M in energy efficiency projects, saving the campus over $8M in annual energy costs.

- We’ve developed an Energy Dashboard to improve system efficiency and annually reduce:

Energy costs by $900,000
Consumption by 19 million kilowatt-hours
Greenhouse gas emissions by 9,600 metric tons

- The campus 69 KV electrical substation converts electricity from 69KV to 12KV, which is charged at a much-lower rate.

- All major campus buildings are networked to a computerized Energy Management System (EMS) that centrally controls building mechanical systems based on occupancy. The EMS is programmed to reduce energy use in buildings during nights, weekends and holidays. Simply changing campus-wide room temperature settings saves hundreds of thousands of dollars annually. The EMS also allows central plant operators to minimize energy consumption by monitoring and controlling heating, ventilating and air-conditioning equipment.

- Establishing a highly innovative, world-class microgrid and "Energy Research Park" that serves as a living laboratory for integrating cutting-edge technology into campus operations. In addition to the cogeneration plant, the microgrid includes:

- Over 2 MWs of solar generation. UCSD also has another 1 MW of solar PV installed at several off-campus sites.

- A 2.8 MW renewable energy fuel cell with a 300 ton absorption chiller that captures waste heat to provide the campus chill water loop additional cooling capacity.

- In addition to a campus 2.5 MW/5MWH advanced energy storage system, a 250 kW/500 kWh energy storage system was recently commissioned at UCSD's off-campus receiving/distribution center.

- Increasing the campus' thermal energy storage capacity from 3.8 to more than 7 million gallons of chill water.

- New EUI targets for new construction are now being developed as part of our climate action plan update.

Of the institution's uncertified building space, what percentage of floor area is maintained in accordance with a water management or benchmarking program? (0-100):

A brief description of the water management or benchmarking program:

UC San Diego updated its water action plan in December 2017. The plan lists actions already taken or to be taken in 8 categories: Housing, Industrial, Irrigation, Laboratories, Office, UC San Diego Health (La Jolla), Restaurants, and Other (including Education and Outreach). Annual potable water use and water saved is reporting to the UC Office of the President for including in the UC-wide Sustainability Annual Report.

UC San Diego is installing Sensus “smart” meters throughout campus that transmit water use data in real time to a central web interface. Access to water use data in real time enables the campus to identify areas that have water leaks and to identify areas where additional water conservation is needed. To date, 400 smart meters have been installed.
