Description of the institution’s certified green cleaning service:
A limited number of cleaning chemicals are used that have been selected for their cleaning effectiveness as well as for their low toxicity. The concentrated chemicals come in premeasured PortionPacs and most are third party certified based on their environmental attributes.
Safety data sheets (SDSs) provide detailed information on the health hazards, physical hazards, personal protective equipment, and proper emergency response measures associated with each chemical.
Each SDS is color-coded to correspond to the color of the appropriately diluted product and matches the color of the printing on the secondary-use bottle.
All Secondary containers have a designated "fill line" and must carry instructions in both English and Spanish as well as a 24 hour number for emergency response information.
Each packet of concentrate is numbered to indicate the size of the container to which the concentrate should be added.
Methods are in place for supervisors to determine if the material is mixed according to directions.
There is also a method of tracking the mixing of hazardous chemicals in various areas of the University.
Plastic bottles for cleaning fluids are refilled rather than disposed of.
Floor area of existing buildings individually assessed for energy performance:
Narrative outlining how building-level energy performance is assessed and how the results are used to improve performance:
Each building on campus is individually metered for steam, electricity, and chilled water, all of which are managed as separate utilities.
Energy Management generates monthly energy forecast reports for some 150 buildings representing about 2/3 of total campus space. Metering data and software algorithms identify higher than expected energy use by utility allowing for timely intervention. Maintenance issues are addressed through the maintenance work order system. Other continued low performers are targeted for retro-commissioning opportunities, including improved control sequences, tuning of control loops, and calibration of sensors.
Target Energy Use Intensity (EUI) metrics are under development for each building type.
Floor area of existing buildings individually assessed for indoor environmental quality (IEQ) performance:
Narrative outlining how building-level IEQ is assessed and how the results are used to improve performance:
Spaces with carbon dioxide monitors.
When CO2 levels rise in these spaces, more outdoor air is brought in.
This reduces energy consumption during unoccupied periods and helps to maintain indoor air quaity for occupants.
Floor area of existing buildings managed or individually assessed for water performance:
Online location of the institution’s minimum standards for water efficient fixtures, fittings, and equipment:
Copy of the institution’s minimum standards for water efficient fixtures, fittings, and equipment:
Narrative outlining how building-level water performance is assessed and how the results are used to improve performance:
Most buildings on campus are individually metered for water and sewer and some for reclaimed water.
The Orange Water and Sewer Authority provided the University with water analytics software, Aqua Vista, that provides interval water use data that can be trended and used for notifications, including leak detection. The software is being used to provide earlier detection of water leaks and to identify high water consumers in different user categories.
