1 2 By implementing the changes listed above1,002,417lbs of CO2,6,451lbs ofSO2and 2 3,374lbs ofNOxwill not be emitted into the environment each year. 1  PacifiCorp; 2  Phil Carver, Oregon Department of Energy

LightingObservations: Typical fixtures are 2 lamp T12 and T8 fluorescent, ceiling mount Lights were often off in unoccupied areas Some lamps were burnt out

Recommendations: Replace all incandescent lamps with compact fluorescent lamps (CFL).CFLs produce light much more efficiently than incandescent and halogen lamps. CFLs also produce less heat, an important factor to consider during the summer months. CFLs come in a widerange of spectra and intensities, so a suitable CFL can be found for almost any application. As part of the audit process, the Sustainability Office will distribute CFLs to building occupants. If you would like a CFL and have not yet received one, please contactus. Replace all T12 fixtures with twin or single T8 fixtures.T8 lamps have a higher efficacy (light output per watt) than T12’s so the same level of light can be maintained while using fewer fixtures and lamps.It is a goal of Facilities Services to replace all T12 lamps on campus, however, due to the quantity of T12’s, this will be a long process. If a department is eager to replace inefficient lighting, and is willing to participate in a costsharing mechanism, certain areas can become a priority. Please contact theSustainability Officefor more information. Report instances of improperlytimed outdoor lighting.Outdoor lighting is usually controlled by either timers or photosensors. If these controls fail, lighting will remain on even if natural light provides sufficient illumination. If you notice outdoor lighting that is improperly timed please contact theSustainability Office. Request occupancy sensors in common areas such as labs, restrooms, kitchens and copy rooms where lights are typically left on. These types of sensors are efficient and easy to install. They automatically turn off the lights if no motion is detected within a specified period of time. Detailed recommendations for specific spaces can be provided upon request. Also available are manuallyactivated switches that have a multioption timer so lights go out after the specified

amount of time. These timer switches are ideal for rooms with windows where electrical lighting may not be necessary during the day. Request delamping for areas that are overlitor areas where natural or task lighting provides sufficient illumination. Please emailsustainability@oregonstate.edufor more information on delamping procedures. Utilize natural lighting wherever possiblemany cases, natural lighting provides sufficient. In illumination for a variety of tasks. In locations where windows allow for enough light to enter the work areas, turn off lighting as it is not needed. Also, by arranging spaces and furniture throughout the building in a way that utilizes natural light to the maximum possible extent, electric lighting use is decreased and occupants achieve superior lighting levels and consistency. If necessary, use task lighting to supplement natural lighting. Request replacement or delamping of burntout fluorescent lampsincandescent. Unlike lamps, burntout fluorescents still consume energy. If the light level in the area is adequate without the lamp lit, please emailsustainability@oregonstate.edufor more information on delamping procedures. If the lamp has been out for more than two weeks and needs to be replaced, contact Facilities Services by email atFacilitiesCustomerServ@oregonstate.eduor by phone at 72969. Notes on specific areas in your building with burntout lamps are available upon request. Computers and peripherals: Observations: Many computers and monitors were observed on in unoccupied spaces Relatively few printers had standby modes enabled Most computer peripherals (speakers, external hard drives, etc.) were on in unoccupied areas

Recommendations: Turn off or standby computersat nightand have them enter standby when not in use for extended periods of time (30 minutes or longer). Standby or shut off monitors that have been inactive for 10 minutes. oOn most computers, power management options can be found under the Control Panel (from StartSettingsHere you canControl Panel). Click ‘Power Options’. designate when your monitor or computer should enter standby. oTurning a computer on and off does not damage its hardware like it once did. Most hard disks are rated at 20,000 on/off cycles. If turned on/off once a day, it would take 55 years to reach this rating number. Manually turn off cathoderay tube (CRT) monitors at nightor during prolonged downtime (10 minutes or longer). Older (pre1995) CRTs consume considerable energy even while in standby or sleep modes. In one case, we measured a 17” CRT using 58W while on and 45W in standby. Turning them off (using the hard switch) guarantees that these monitors are not drawing a large phantom load. Purchase liquid crystal display (LCD) monitorswhen replacing CRT monitors or for new workstations. LCDs use considerably less energy and cause less eye strain, and their slimmer ™ profile increases useable workspace. ConsiderEPEATor Energy Star®certified products (http://www.epeat.net/,http://www.energystar.gov/stringent energysaving and) which meet environmental criteria. Turn off printers at night (especially laser printers)that typically are on all day. Laser printers consume considerable amounts of energy even while in standby mode; according to

manufacturer’s specifications, several laser printers inventoried during the audit consume over 100W while in standby! The average standby power draw is 35W. If high volume printing is not necessary, recommend that staff use inkjet printers, which typically use considerably less energy (<5W) when in standby. Network printerswithin workgroupsso that the total number of printers can be decreased. Using the highcapacity printers to their fullest capability will save energy as well as decrease the need for purchasing numerous different print cartridges. These larger printers are also more commonly capable of printing on two sides, decreasing the volume of paper purchased. The cost of a conduit to network a printer is around $100. For more information, please contact sustainability@oregonstate.edu. Use a surge protector for computer peripherals and other accessories. While many computer peripherals like speakers, scanners and external hard drives do not use very much energy (< 5W), the accumulated energy consumption is significant. By having them all plugged in to a surge protector, not only are they protected from fluctuations in current, they also can be easily shut off at night or during extended periods of downtime. Use laptops in place of desktops when appropriate.Laptops use considerably less energy than a desktop (2030 W vs. 100150 W) and do not require an uninterruptible power supply. A laptop docking station allows for desktoplike function while at work or at home while allowing the full portability required of a laptop. Decrease time at which copiers and printer enters powersave mode to 15 minutes. Other Electrical EquipmentObservations: 201 regular size refrigerators and 39 small refrigerators were observed 36 microwaves and numerous coffeepots, space heaters and fans were noted Several rooms were observed with ovens and autoclaves turned on, but not in use Recommendations: Plug accessories into a surge protectorso they can be easily shut off at night and on weekends. Many of the accessories listed above require a constant power supply to power displays and maintain system functions. While this phantom load is usually small for an individual piece of equipment, the aggregate power consumption can be surprising. A surge protector is a safe and convenient way to protect these devices while allowing the user a fast and simple way to shut them off when they are not in use. Consolidate contents of seldomused refrigerators to reduce the number of total refrigerators.Also consider consolidating the contents of minifridges into large, shared refrigerators, which are more efficient. Small ‘mini’ refrigerators use between 200 to 300 kWh annually. A new, fullsized refrigerator uses only about 600 kWh to cool a volume many times greater.

Consider replacing fridges that are made before 1990.Due to technological advances, newer fridges are at least 50% more efficient than pre1990 models. Contact theSustainability Officefor information on rebates and incentives, as well as potential costsharing opportunities. Tips for efficient refrigerator and freezer use:oKeep fridges 2” away from the wall and cleancoils every 6 months oClean or replace gaskets on doors to maintain an effective seal oSet refrigerator temperature to 40°F and freezer to 0°F oFill empty space with jugs of water in the fridge and blocks of ice in the freezer. This minimizes the cooling loss of opening the fridge or freezer door. Consider unplugging industrial and scientific equipment when not in use.A large number of small pieces of scientific equipment appeared to be always on. Also several heating and cooling units were observed on while not in use. Small scientific equipment may not use much electricity individually (525 W) but the cumulative impact can be significant, especially in a building the size of Cordley. Larger equipment such as autoclaves and ovens use substantial amounts of energy and care should be taken to ensure these are off when not in use. Recycling Observations: Many offices and labs lacked paper and comingled recycling bins Recommendations: Ensure enough recycling bins are located to be convenient for all office occupants.Ideally, a commingled recycle bin would be adjacent to every trashcan in a common area. For more information on recycling, please visit the Campus Recycling website at http://recycle.oregonstate.edu/or contact themvia emailOther Notes: If your office space generates electronic waste,consider participating in a new electronic media recycling program offered by Campus Recycling.Items such as CDs, CD cases, 3.5” floppy discs, and audio/visual tapes are accepted. For more information on this program, contact Campus Recycling.Purchasing Recommendations: Consider Energy Star® products when replacing appliances and office equipment. These products are typically 1030% more efficient than nonrated models and the purchase price difference is oftentimes negligible. ™ Consider EPEAT certified computers and accessorieswhen purchasing new equipment. ™ EPEATevaluates products on a widerange of environmental criteria, ranging from energy consumption and materials to toxic content and endoflife management.

Paper UseObservations: Approximately 1,132 reams of white 30% recycled and 24 reams of colored 30% recycled paper are used annually in Cordley(578,000 sheets). Pleasecontact usfor department specific paper consumption information. Recommendations: On all computers, set doublesided printing as the default setting for printers with this capability. Encourage printing on clean side of singlesided paper.Add small boxes near printers containing this draft paper or leave a stack of this paper in printer bypass feeders. Consider purchasing recycled paper with a high postconsumer content (50%+)for your space. Recycled paper is compatible with all printers and costs only slightly (15%) more than virgin material, while significantly reducing the environmental impacts of printing. Heating & Cooling Observations: 10 window/personal air conditioning units were observed Many building occupants commented on inefficient and ineffective environmental controls Recommendations: During the building audit, many people commented on theinefficiency and ineffectiveness of the HVAC system.Currently an engineering consultant is evaluating Cordley Hall heating, ventilation and air conditioning (HVAC) to help alleviate this problem. In the meantime, please help us try to decrease the amount of wasted energy that contributes to the problem. Also, continue to contact Facilities Services and the Energy Management Shop so that issues with HVAC are documented. Consider alternatives to forced air space heaters.While effective in small, wellinsulated spaces with low ceilings, forced air space heaters are inefficient in areas where the warm air can easily escape or rise above the occupied zone. Alternatives allow for equal comfort while using significantly less energy. Radiant heaters use 100200W, compared to 1500W for forced air heaters, and users report increased comfort at lower air temperatures. Radiant heaters are also preferred from a fire safety standpoint. Try these energysaving tips to keep yourself comfortable: oDress appropriately for the weather: wear light, breathable clothing in summer and layer clothing during the winter oUse fans instead of AC units, and radiant heaters (which heat you and not the air) instead of space heaters oClose shades or blinds during hot days (keeps heat out) and on cold nights (keeps heat in)

In winter, limit air infiltration with a draft stopper. There are many different options, but a simple and inexpensive solution is to use a towel or a window ‘sock’ to block air from entering the space. Other options like interior storm windows are available.Contact usfor more info. Turn off exhaust fansFans consume significantin areas where they are no longer needed. amounts of energy, especially if warm building air is being vented to the outside needlessly. If a space no longer requires a high level of ventilation, please contact the Sustainability Office at sustainability@oregonstate.eduto have the fan shut off or removed. Remove personal AC units from windows during cool months.These AC units allow considerable air infiltration, increasing heating demand while providing no benefit.Water Conservation Observations: Very few hand washing sinks had aerators that limited flow to 1.0 gallons per minute (gpm), an accepted industry standard Recommendations: Request aerators to limit flow on hand washing sinks to 1.0 gpm maximum. Unless a sink is used for filling, 1.0 gpm is an adequate amount of water for hand washing while conserving water. Report leaking faucetsto theSustainability Office. A leaking faucet with 30 drips per minute can waste over a thousand gallons of water per year.
