Buildings and Grounds: Management of Energy, Water, and More

人妻诱惑's Facilities Services tracks energy usage as it impacts 人妻诱惑's carbon footprint. It seeks to properly maintain and operate equipment to reduce consumption without compromising environmental comfort. They compare the amount of energy used on an annual basis to determine how efficiently the campus is operating over time. The college implements multiple strategies to obtain efficient use and strives to continue to find opportunities to reduce energy consumption on a square-foot basis by making mechanical improvements, sequencing operations, and controlling strategies for optimum performance.

人妻诱惑 partnered with Ameresco for a comprehensive three-year energy use audit. As a result, 人妻诱惑 committed $5.4 million to implement changes to minimize energy use by maximizing equipment life and altered building management. Changes resulted in verified savings of $283,000/year for electricity, water, and natural gas.

人妻诱惑 participates in . This is a demand response program in which participants reduce or shift energy use for a few hours when demand is high—usually hot summer or cold winter days. Using less energy during these times decreases the need to buy more expensive power to meet that demand, which helps keep energy prices lower for everyone. In 2020, we shifted 18% of our energy load, using less energy when others were using more.

Commitments to sustainable practices in 人妻诱惑 buildings are evident in the following:

All building mechanical systems are linked through a central computerized energy management system for optimum natural gas savings
Low-voltage lighting, time clocks, motion detectors, and light sensors minimize electricity use
Low-flow nozzles on sinks and showers and low-volume toilets in restrooms ensure efficient water use
Considerations for lifetime efficiency in building materials and mechanical systems for new construction and upgrades
Limits on the use of air conditioning (78°F/summer) and heating (68°F/winter)
3% of our public purpose charge invested in clean wind initiatives
Use of a central boiler plant and steam tunnel for efficient heat delivery
Regularly scheduled preventative maintenance program for mechanical equipment
Use of variable frequency drives (VFDs) for new mechanical installations and replacements to increase efficiency and reduce motor load and operating costs
Conversion from pneumatics to all-digital controls
Research on energy-effective procedures and equipment upgrades
Treatment of boiler water with minimum chemistry and best recovery
Deaeration and maintenance of line conditions for optimum operation of the central steam plant
Use of only low-VOC paints
Use of natural gas in fire tube boilers that can burn oil for backup capacity when gas is curtailed
Use of biodiesel in campus boilers when required to use alternative fuel to natural gas
Use of biodiesel in grounds equipment
Use of synthetic oils for vehicles, mowers, and tractors owned by Facilities Services
Use Buckeye Eco cleaning products, which are safer for the user and the environment, by cleaning crews

人妻诱惑's Facilities Services monitors our water usage to confirm we are using it wisely. The college is fortunate to have the premier water rights on Crystal Springs, which allows us water for irrigating our 116-acre campus. This not only results in water cost savings, but also avoids reliance on the city water supply.

Stormwater management is a major concern in Portland. It rains 154 days out of the year, averaging just over 39 inches annually. Stormwater has to be transferred by an underground pipe system and goes to rivers and streams, eventually to the Willamette, then the Columbia, and eventually out to the Pacific Ocean. During high-rain events, the Willamette and Columbia rivers can exceed flood stage, causing significant erosion and other problems. Creating swales and other stormwater facilities that slow water down and keep it on site is essential in diminishing downstream flows. 人妻诱惑 has stormwater facilities on site that manages almost all the rain that falls on campus.

A campus-wide drain mapping project was completed in 2012. It was determined that most of the drains on 人妻诱惑 campus lead directly to the canyon. Unwanted contaminants can potentially follow the same path. The predominant pattern of the drain systems has a group of drains collected to one outfall. These outfalls are generally north of their field of drains. Most drains have a trap within them that collects about two or three gallons of substances lighter than water before discharging into the canyon. However, water-soluble contaminants bypass the trap system and discharge immediately. As a result, drain blocking mats were purchased and stored near all drains on campus for fast emergency access and response.

Examples of Building-Specific Efforts

New sensors triggered by carbon dioxide have been installed in buildings, such as Kaul Auditorium, to activate the heating system when people arrive. The sensors can measure the number of people in the room by the carbon dioxide they exhale and adjust the air intake accordingly.
Solar panels have been installed on the roof of the Theatre Annex to offset its energy consumption and that of the two warehouses, the Birchwood Apartments, the 人妻诱惑 College Apartments, the Health and Counseling Center, 28 West, and the Farm, Garden, and Canyon houses.
