ENERGY & WATER OBJECTIVES
- Reduce the total energy use of the jails by 10% by 2015. 20% by 2020 and 30% by 2030.
- Reduce water use 10% by 2015, 20% by 2020 and 35% by 2030.
Sustainable Jail Project objectives include reducing energy and water use in jail facilities. Energy and water utility costs are a major expense in jail operations, and jails are the largest consumers of energy and water in Multnomah County government facilities. Investments in water and energy conservation not only save money, but help mitigate against future energy cost increases, and protect the environment and public health.
- Hot water heat recovery at the jail laundry reduced energy consumption by 50%.
- Installing energy monitoring dashboard to track energy use and trends in facilities.
- Replacing inefficient lighting with energy saving high-efficiency alternatives.
- Upgrading the Justice Center chiller resulted in 30% energy efficiency improvement.
- Installing a white roof has resulted in reduced heat absorption.
- Consolidating training facilities in one building reduces fuel consumption and emissions and saves $9,000.
- Purchasing vehicles with greater fuel efficiency and reduced emissions.
- Installation of laundry facility heat and water recapture retrofit will result in $57,000 annual cost savings and 80% reduction in water consumption.
- Installation of pre-rinse spray valve on commercial kitchen sinks.
- Installation of timers on inmate’s showers and sinks.
- Installation of high efficiency shower heads in jails with a flow of two gallons per minute.
- Introduction of rain sprinkler heads to deactivate sprinklers during precipitation.
